Cisco Networking:

Cisco Systems, Inc. (NASDAQ: CSCO, SEHK: 4333) is a multinational corporation with more than 63,000 employees and annual revenue of US$35 billion as of 2007. Headquartered in San Jose, California, it designs and sells networking and communications technology and services under five brands, namely Cisco, Linksys, WebEx, IronPort, and Scientific Atlanta.

Cisco Certifications:

Cisco Career Certifications are IT professional certifications for Cisco products. The tests are administered by Pearson VUE (Prometric previously administered the test; but as of 1 Aug 2007, no longer does).

There are three levels of certification:

* Associate,

* Professional, and

* Expert.

Associate certifications:

* Cisco Certified Network Associate (CCNA)

* Cisco Certified Design Associate (CCDA)

Cisco certified network associate (CCNA):

Candidates have the option of gaining the certification by passing two tests (ICND1 640-822 and ICND2 640-816), or one single test (CCNA 640-802); the two-test option has the advantage of allowing the candidate to focus on certain subjects.

The certification is valid for three years; at that time a CCNA holder must either

* re-take the CCNA or ICND exam, or

* take and pass an exam for one of the Professional (e.g., CCNP) or Specialist level certifications (excluding the sales specialist exams), or pass the CCIE written exam.

These exams are known by their corresponding numbers. When the curriculum of the exam changes the exam number also changes. The current exam number for CCNA is 640-802 (from 15 Aug 2007). New ICND Part1 (640-822 ICND1) and ICND Part2 (640-816 ICND2) available from 15 Aug 2007. Part 1 by itself will give you a CCENT.

These exams are conducted by authorized test centers at a cost of $125 USD each for the ICND1 or ICND2 exams and $150 USD for the full CCNA exam.

There is also the Cisco Networking Academy, which brings the CCNA and CCNP curricula into traditional educational institutions in over 150 countries.Students enrolled in Cisco Networking Academy can request exam vouchers that allow them to take the retired exam for an extended period of time.

Cisco Certified Design Associate (CCDA):

The CCDA certification indicates an apprentice knowledge of Cisco network design. Individuals who have earned a CCDA are capable of designing switched or routed networks consisting of LANs, WANs, and various dial services. While a CCNA certification is not required to take the CCDA exam, Cisco recommends being familiar with CCNA material. Also recommended is knowledge of BCMSN.

Professional certifications:

* Cisco Certified Network Professional (CCNP)

* Cisco Certified Design Professional (CCDP)

* Cisco Certified Internetwork Professional (CCIP)

* Cisco Certified Security Professional (CCSP)

* Cisco Certified Voice Professional (CCVP)

Cisco Certified Network Professional (CCNP):

The CCNP is considered proof of having the ability to work with medium-sized networks (between 100 and 500 end devices) and with technology such as QoS, broadband, VPNs, and security-minded features. To acquire a CCNP one must possess a CCNA certification first and then pass three or four tests, depending on the path one chooses. The four tests path requires the candidate to pass the following tests:

* 642-901 BSCI: Building Scalable Cisco Internetworks (BSCI) – Deals with routing

* 642-812 BCMSN: Building Cisco Multilayer Switched Networks (BCMSN) Deals with switching

* 642-825 ISCW: Implementing Secure Converged Wide Area Networks (ISCW) – Deals with wide area networks

* 642-845 ONT: Optimizing Converged Cisco Networks (ONT) – Deals with using Qos to tune networks to work effectively with IP Telephony.

The BSCI and BCMSN tests can be taken as one single composite test known as the 642-892 Composite which covers subjects for Building Scalable Cisco Internetworks (BSCI) and Building Cisco Multilayer Switched Networks (BCMSN).

In order to retain the certification one must either re-certify or pass one of the CCIE written exams before the Professional certification expires. Additional resources and tools to aid in preparing for the certification are available on the CCNP Prep Center.

Cisco Certified Design Professional (CCDP):

The CCDP certification is an advanced network design certification provided by Cisco Systems, Inc. Candidates for the certification are tested for advanced knowledge of Cisco devices and the way to interconnect them. This certification is considered a professional level certificate by Cisco Systems. (The CCNA and CCDA are prerequisite.)

Cisco Certified Internetwork Professional (CCIP):

The CCIP certification is a professional certification covering the end-to-end protocols used in large scale networks.

To attain this certification tests must be passed in the areas of routing, BGP, MPLS and Quality of service.

Cisco Certified Security Professional (CCSP):

The CCSP certification is an advanced network security certification. Candidates for the certification are tested for advanced knowledge of various Cisco security products.

To attain this certification several tests must be passed in the areas of VPN, IDS, PIX firewall, Secure IOS, the Cisco SAFE, as well as having a CCNA or higher level certification (e.g. CCNP or CCIP).

The common practice is to take five exams which include one elective paper. The list of exams and elective papers can be found in the Cisco website.

Cisco Certified Voice Professional (CCVP):

The CCVP is a certification covering all aspects of IP Telephony/VOIP networks and applications.

To attain this certification, five tests must be passed in the areas of Quality of service, Cisco VoIP, IP Telephony Troubleshooting, Cisco IP Telephony, and Gateway Gatekeeper.

Expert-level certifications:

The expert-level certification is the Cisco Certified Internetwork Expert (CCIE). It is the highest level of professional certification that Cisco provides. There are 5 active CCIE tracks, as shown below. As of April 6, 2008 there are 16,335 people with active CCIE certifications in the world.

Cisco began its CCIE program in 1993 originally with a two day lab, later changing it to the one day format used today. Fewer than 3% of Cisco certified individuals attain CCIE certification, and on average will spend thousands of dollars and 18 months studying before passing. Many candidates build mock-labs at home using old Cisco equipment, selling it again to other candidates after passing. Alternatively candidates may rent “rack time” online and practice lab scenarios on Cisco equipment hosted on the Internet for that purpose.

Cisco refers to the CCIE as the “most respected IT certification”, and from 2002 to 2005 it was voted as such in CertCities magazine. It has also been voted the most technically advanced IT certification by CertMag, and is generally reported as the highest salaried certification in IT salary surveys.

The CCIE is comprised of a written exam and a “lab” exam (each in the specific area of the chosen track). The written exam is required to take the lab exam, and has a cost of $315 USD per attempt. Upon passing the written exam, the candidate is qualified to have a first attempt the lab exam for 18 months. If the first attempt is unsuccessful the candidate has 3 years from the date the written exam was passed to successfully complete the lab. If a candidate does not pass the CCIE lab in that time, they must pass the CCIE written exam again before making additional attempts at the CCIE lab exam. As many attempts can be made to pass the lab exam for up to 3 years after passing the written, so long as the first attempt is within 18 months. There is a minimum waiting time between attempts of one month.

The CCIE Lab is currently $1,400 USD per attempt and are offered only at ten Cisco lab exam locations worldwide. The locations are Bangalore; Beijing; Brussels; Dubai; Hong Kong; Research Triangle Park, NC; San Jose, CA; São Paulo; Sydney; and Tokyo. Some CCIE tracks do not have lab exams available at all locations. For example, the Storage Networking lab is available only at the Research Triangle Park, NC and Brussels locations. In addition, according to a survey by Cisco the average cost to prepare for CCIE certification is $9,050 as of April 2006, spent mostly on practice equipment and self study material.This is partially offset by the increased salary the certification commands, which a March 2007 Network World article estimates at 10% – 15% over similarly experienced engineers who do not have a CCIE.

The lab is an 8-hour hands-on exam designed to demonstrate that the candidate not only knows the theory, but is also able to practice it. Many prospective CCIEs need multiple attempts to pass the lab exam.

There are no formal prerequisites for the CCIE exam, but Cisco recommends one has at least 3 – 5 years experience in networking before attempting to become a CCIE. CCIE was the first Cisco Certified qualification, and as such there were no other certifications that could be taken prior. The development of the associate and professional certifications was due to recognition of the fact that a CCIE is overkill for many networking personnel, and also for the vast majority of businesses who employ such people, and that certifications needed to be offered at lower levels. Despite the development of the lower certifications, Cisco has chosen not to make them formal requirements for the CCIE certification.

It is possible to hold multiple CCIE certifications. This is done by passing both the written and the lab exam in a particular track. As of November 14th, 2007 there are 1,344 individuals who hold multiple CCIE certifications. Of those, 210 hold three or more CCIE certifications.

* CCIE Numbering

* CCIE Routing & Switching

* CCIE Security

* CCIE Service Provider

* CCIE Voice

* CCIE Storage Networking

* CCDE

CCIE Numbering:

Upon successful completion of the hands on lab exam, a new CCIE is awarded a CCIE number. The first CCIE number allocated (in 1993) was 1024, and has increased incrementally from there. A lower number indicates that the CCIE was awarded some time back, a higher number indicated a more recently awarded certification. As of February 2008, the highest CCIE number allocated was just over 20000.

Number 1024 was allocated to the first CCIE lab location, rather than to an individual, and featured as a plaque at the entrance to the lab. Number 1025 was awarded to Stuart Biggs, who created the first written exam and first lab exam. The first person to pass both CCIE written and lab exams was Terrance Slattery, who was consulting to Cisco at the time when the lab was being devised. Terry Slattery (CCIE 1026) was therefore the first CCIE who passed both exams, and the first CCIE who was not an employee of Cisco.

Any CCIE who obtains further CCIE certifications, is not awarded any further numbers, the new CCIE certification is awarded under the same number as the original.

CCIE Routing & Switching:

The Service Provider track focuses on networking in the service provider industry. Subjects include Optical networks, DSL, WAN switching, Voice over IP, Content Networking, Broadband Cable and Metro Ethernet.

CCIE Voice:

The Voice track concentrates on voice solutions for the enterprise and includes subjects such as QoS, MGCP, Call Manager (Cisco’s VoIP PBX), Cisco Unity (Cisco’s Unified Messaging platform), Unity Express and IP Contact Center Express.

CCIE Storage Networking:

The latest addition to the CCIE certification tracks is the CCIE Storage Networking track. As the name suggests, the Storage Networking track concentrates on storage networking topics, such as Fibre Channel, iSCSI, FCIP, Intra VSAN Routing and FICON.

CCDE:

Cisco Certified Design Expert CCDE Assesses advanced Network Infrastructure Design Principles and Fundamentals for large networks. A CCDE can demonstrate an ability to develop solutions which address planning, design, integration, optimization, operations, security and ongoing support focused at the infrastructure level for customer networks.

Prerequisites for CCDE There are no formal prerequisites for CCDE certification. Other professional certifications or training courses are not required.

Recommended Training and Experience It is expected that the candidate will have an in-depth understanding of the topics in the exam blueprints, a minimum of seven years job experience, and a thorough understanding of networking infrastructure principles. Please view the written exam information page for more details.

Step One: CCDE Written Exam You must pass the two-hour, written qualification exam which covers advanced networking infrastructure design principles and concepts. Once you pass the qualification exam, you are them eligible to schedule the practical exam.

Step Two: CCDE Practical Exam The CCDE practical exam is still in development, however it will be an eight-hour exam that will test your ability to identify, manage, and create advanced solutions for large scale networks. You must pass the lab within three years of passing the written exam in order to achieve certification.

Engineering Crossing asked:


The availability of jobs for network engineers and systems administrators is expected to grow by more than 27% per year from 2004 to 2014, according to data provided by the Bureau of Labor Statistics. A network engineer may also be referred to as a network administrator, systems administrator, network analyst, network designer, network architect, WAN administrator, LAN administrator, IT systems administrator, network operations analyst, or network technician. The principal job of a network engineer is to run and oversee computer communication systems and data transfer within an organization or between companies. Computer networks are used by companies to collect and process data, access the Internet and web-based utilities, and share files and resources. The network engineer serves as both a road engineer and a police officer directing traffic on the information superhighway.

The Duties of a Network Engineer Network engineering jobs involve the designing and maintenance of both hardware and software components of computer networks. Network engineers are specialists in constructing and maintaining local area networks (LANs) or wide area networks (WANs). All of the elements within an organization’s IT system, including individual desktop PCs, file servers, mail servers, backup servers, application servers, custom-designed workstations, and more, come within the purview of the network engineer’s job.

Here are some of the tasks network engineers commonly perform:

* selection of hardware and software solutions for organizational needs

* implementation of hardware and software solutions and utilities

* testing and resolution of system issues, including compatibility issues

* analysis of organizational needs

* building IT networks to support organizational needs

* troubleshooting and ensuring smooth network operations

* upgrading equipment and systems

* maintaining network and data security

* establishing user accounts and passwords

* providing compatibility training

* documentation of problems and solutions

* analysis and design of networks

* researching objectives of new or current networks

* apprising existing networks and IT solutions

* designing networks to maximize productivity

* monitoring networks to find and establish regular behavioral patterns

* protecting and extending equipment life

* educating end users

The Skills of a Network Engineer

Network engineers must possess technical backgrounds; a systematic understanding of computer hardware, applications, and operating systems; and technical knowledge of networking hardware and software. A networking engineer generally must possess:

* an understanding of networking principles and influencing factors

* thorough knowledge of routing protocols and switching technologies

* an understanding of network security systems, strategies, and procedures (repetition)

* specific knowledge of WAN/LAN infrastructure

* a mastery of scripting languages

* expertise regarding server products and technologies

* familiarity with industry protocols

* experience with IP addressing, including subnetting

* experience with troubleshooting router, switch, and fault-tolerant or redundant environments

* hardware maintenance skills

* strong communication skills

* motivation

* decision-making ability

Working Hours and Environment

It is standard for network engineers to work around 40 hours per week. However, time spent installing new systems or conducting maintenance often extends beyond normal working hours. Network engineering jobs are usually in metro environments.

How Does One Become a Network Engineer?

Network engineers typically have IT backgrounds as well as bachelor’s degrees or higher-level educational qualifications. Certifications from institutes and organizations like Microsoft and Cisco also carry weight with employers. Engineers with different IT-related backgrounds or specializations in network design, operations, and related fields can become network engineers. Many universities and colleges offer degrees in network engineering. There are also network management and network engineering programs at various higher education institutions. Working network engineers often upgrade themselves by acquiring specialty certifications from industry organizations like Microsoft.

Prospects for Network Engineers

As mentioned earlier, job prospects for network engineers are expected to grow at a rate greater than 27% per year. The average salary of a network engineer ranges from $50,000 to $70,000 per year.

Jonathan Mac asked:


We are almost at the end of the glorious year, 2008. Everyone using the Internet would be aware of the fact that the social networking websites have gained huge popularity through this whole year. And it’s now the ideal time to make a review on the 5 best social networking sites of the year 2008. There were no much changes from the start of this year and the reigning champions are:

1. Myspace

2. Facebook

3. Bebo

4. Friendster

5. Hi5

The winner is Myspace

Almost every Internet user knows what Myspace is and more than 80% of them would have used Myspace. The key factors of the success of this social networking giant are, unique social networking web design, the easiness in sharing pictures, communicating with friends, and option to create the best customized social networking profiles. Another cool feature of myspace which we loved is the independent music bands anchored on myspace for easy music discovery. With loads of social networking features enabled through social networking softwares and all of them available for free, Myspace is the Winner.

Facebook – The contender

Facebook, yet another popular social networking website has been a serious competitor of Myspace. With the cool social networking softwares made available, facebook has become addictive to many teenagers (still no harm to them). With top notch security features, facebook is one of the most preferred social networks. So here is what holds facebook back off the winner circle. It is the limited customization options that facebook offers. However, considering all other social networking features that facebook offers, it receives the silver award. Facebook is the contender.

Bebo and Friendster – The Quickly grown Social networks

The growth of the popular social networking site- Bebo and friendster was very quick. These two social networking websites remained unknown by the start of this year and today the reached the 3rd and 4th positions of the social networking website rankings. Bebo, being bought by AOL is gaining popularity each day in the United States. Like all other social media sites, there are cool social networking softwares, personalization and privacy settings. Bebo and Friendster are in the 4th and 5th place respectively.

The rise of other social networks

The popularity of social networking has driven many people to have their own social networking website. With the social networking website design becoming easier each day, many online marketers have created their own business social networks. Though these social networking websites doesn’t appear on the top 50 rankings, they are of great use to the creators. Though these social networks, online marketers are able to promote their products, understand customer needs and get more exposure to their business. With the easiness of social networking website design we are now expecting some huge changes in the rankings of social networking websites in the year 2009.
