Computer networks and the internet have dramatically changed the way we live our lives. Computers are now in constant communication with each other making possible transactions such as online shopping, seat reservation and even email.
However, all this is only possible thanks to accurate network timing and in particular the use of Network Time Protocol (NTP) used to ensure all machines on a network are running the same time.
Timing synchronization is crucial for computer networks. Computers use time in the form of timestamps as the only marker to separate two events, without synchronization computers have difficulty in establishing the order of events or indeed if an event has happened or not.
Failing to synchronize a network can have untold effects. Emails may arrive before they are sent (according to the computer’s clock), data may get lost or fail to store and worst-of-all, the entire network could be vulnerable to malicious users and even fraudsters.
Synchronization with NTP is relatively straight forward as most operating systems have a version of the time protocol already installed; however, choosing a timing reference to synchronize to is more challenging.
UTC (Coordinated Universal Time) is a global timescale governed by atomic clocks and is used by nearly all computer networks across the globe.
By synchronizing to UTC a computer network is essentially synchronizing the network time with ever other computer network in the world that uses UTC.
The internet has plenty of sources of UTC available but security issues with the firewall means the only safe method of receiving UTC is externally. Dedicated NTP time servers can do this using either long wave radio or GPS satellite transmissions.

Ten considerations when choosing a Computer Network Consultant.
In today’s increasingly complex computer age finding a great computer network consultant is imperative. The life of your business depends on it. Think about what would happen if your entire system were to crash. It could literally take years to regain all the client and product information you have worked so diligently to collect. How long would it take to get business running smoothly? “Ten considerations when choosing a computer network consultant” is a guide to selecting the right consultant in which to put your trust.
1. As with any project the first order of business is to lay out an organized plan. In order to maximize both yours and the consultant’s time, be sure to set written goals and expectations, and find a consultant who has the experience and knowledge to complete the project at hand.
2. Choose a consultant who will make the necessary time for face to face communications. This is most important at the beginning of the relationship. Much time and energy wasted can be avoided by sitting with the consultant initially for the amount of time necessary to make sure there are no misunderstandings.
3. She or he needs to be open to learning your organization’s systems, in order to make the most of its strengths and minimize its weaknesses. She or he should suggest a variety of options for improvements. Throwing the entire system out and starting over from scratch might be a quick easy way to approach your network but might not necessarily be the right solution. Find a consultant who is willing to do the work and provide you with several options.

State of the art network adapters have been manufactured to meet the needs of complex commercial and corporate computer networks. These networks not only include computers and peripheral devices such as scanners, writing pads and printers but also include more complex data storage vaults like servers. With all these advance machines and devices working together you need compatible and reliable networking systems to support this advance platform. Form the said purpose you can either install routers or you can use network cards and adapters. With both of these strategies you will get impressive performance and an acceptable data transfer rate. Network reliability and resilience is another issue that is important and must be taken into serious consideration, if you want a successful and effective computer network. To make your network effective and efficient you need to invest money and time in developing different network topologies and strategies. These decisions will affect the performance of networks directly.
Network cables are available in different construction to suit your diverse demands. Some of these cables are flexible, some are hard and cannot flex easily, some of them are resistant to network noise and some of them are resistant to fire and high temperatures. To effectively increase the network performance you can use several different network cables such as Patch cables, Ethernet crossover cables, RJ-45 connector cables, fibre optic cables and more advanced T1 and T3 lines. With these state of the art cables you can design a network that provides optimum performance under all situations.
Weak Ethernet cables and network cards will result in loss of network signals and loss of transmitted data. Data loss, file corruption, data security breach and network bottlenecks are symptoms of a weak network that is a result of faulty network strategy. To develop a perfect network you need to spend reasonable amount of time on your desk figuring out network topologies. It all depends upon the final strategy that which hardware and network cable system you are going to implement?

Things are much different than they were 10 years ago. In today’s world, Internet applications and network systems are growing increasingly complex. There are many more protocols, languages, features and capabilities than ever before, but not only this, the amount of traffic and data being pushed across the networks have increased tremendously.
As such, detecting vulnerabilities or network weaknesses can take much longer than in the past. More importantly, hackers or malicious software are utilizing a wider variety of methods that can cripple or even compromise a business’s integrity. In the past, such attacks have been utilized to bring down even the largest corporate applications and servers.
Beyond network attacks, other common problems in the IP and networking world, are server delays, server overload, application slow down, and traffic spikes.
No one is immune to these kind of network issues, but there are powerful solutions already hitting the market that can test and eliminate most network problems much earlier than previous technologies.
Any company specializing in the protection and security of network infrastructures knows that proper testing and network emulation is one of the best ways a business can prevent network outages and application failures. Almost all network issues can be prevented with the appropriate testing, know-how and equipment.
In this article we will be reviewing the two competing network testing companies, Ixia and Spirent and their respective products.
Ixia specializes in Converged IP Performance Testing with clients in over 30 countries including Network and Communication Corporations, Electronics Manufacturers, Governments, and Enterprises.
Spirent Communications is a British Telecommunications company dealing in communications and network testing.
We got our hands on a number of products from Ixia and Spirent, namely the IxChariot, IxLoad, Ix Test Conductor, and Spirent Avalanche.
