When your car starts to get sluggish you pop the bonnet and check the individual components underneath. So why is it that when our networks start to run slow the components are often the last thing consideredWe take the blame off the network itself by giving you 1. When most peoples idea of a network was a workgroup LAN, it either worked or it didnt. If it didnt, the most likely causes were a crashed server or a disconnected co axial cable. Todays enterprise networks are far more complex, with more potential sources of failure or degradation, and a wide variety of different traffic types competing for scarce resources. One effect of this complexity is that there are many different components that can be managed, supplemented, replaced, or just plain tweaked in order to get the performance levels required. We trawled the industry and have come up with 1. Understand your network. Without having an understanding of whats actually happening on your network, you are likely to fail at any attempt to address performance issues. Peter Prichard, marketing director Asia Pacific at Compuware, says people tend to blame the network for poor performance, but the PCs and servers can also be the cause. The first thing to do is make sure the network really is the problem, Prichard says. Even if its not the network, IT spends a lot of time proving its not. Tools such as Compuwares Vantage suite can isolate problems such as a slow client, excessive latency on a WAN link, or poorly written SQL on a back end server. An application might be developed on a LAN and then deployed over a WAN with disappointing results due to an excessive number of database calls. This sort of analysis may reveal things you didnt know about your network, such as a 1. Mbps WAN link when youre paying for 2. Mbps, says Peter Owen, territory manager at Packeteer. Collecting the right information also lets you take an active stance, identifying and dealing with problems before they impact on users. Many people will blindly add bandwidth in an attempt to solve a perceived problem this tends to be one of the biggest mistakes people make, Prichard says. Youve got to have facts application based facts, he says. David Gibb, technical consultant with Vanco Australasia agrees. He says that what may dramatically improve performance in one environment could hinder performance in another. Scott Atkinson, managed LAN services practice leader at Netforce, points out, there are a variety of free, cheap, and expensive tools that singly or in combination can show whats happening and why.

MRTG Multi Router Traffic Grapher, a free utility from http people. A network analyser itself will only show the aggregate traffic, and wont deliver the information you need. Prichard says to start with the premise that the application is king, rather than checking individual aspects of the infrastructure. Lorenzo Modesto, general manager at Bulletproof Networks, says this monitoring should be accompanied by alerting. Once the monitor is tuned to avoid false positives, an appropriate person should be automatically alerted when an unusual event occurs. SMS is absolutely perfect for that, he says. When it comes to things such as radio frequency, monitoring is important for good wireless LAN performance, says Mark Hayes, manager of consulting and solutions at CSC. The RF environment is not static, he says. According to Hayes, a WLAN coming online on a close neighbours premises can affect the performance of your network. Quality of service and packet shaping. One way of improving perceived performance is to ensure that the most important applications get priority. Typically, applications are allocated to classes of service typically platinum, gold, silver, and bronze, and then policies are set for each class. For example, platinum traffic might be guaranteed at least 5. Three or four categories are typical, says Danny Price, solutions manager at Vanco Australasia, but some organisations use as many as six. A larger number is too hard to manage, he says. Some category decisions are easy, such as blocking or severely limiting peer to peer file sharing, says Owen. Packeteers software supports auto discovery and auto configuration, after which priorities can be fine tuned to suit the needs of the organisation. The traffic shaping capabilities of routers are generally all that you need to get you started, says Atkinson. A lot of places dont take the basic steps. If further improvements are needed, the Packeteer Packet. Shaper is a good product, he says. Hayes warns that people dont always understand the impact of packet shaping, which can be negative if not done correctly. We understand the applications and how to configure the Packeteer devices to provide the appropriate performance for the applications along with detailed reports that the network administrator needs, Hayes says. Path optimisation can be used in conjunction with service classes, says Steve Wastie, director of strategic alliances at Peribit. For example, two sites might be connected by frame relay plus a higher bandwidth VPN link via an ISP. ERP traffic might always be sent by frame relay, while internal e mail goes across the VPN as long as the latency does not exceed 2. This makes good use of the infrastructure, and is a critical enabler for us, Wastie says. Vasona Networks works with global mobile network operators to deliver better subscriber experiences over better utilized network resources. Modesto points out that you may need to shop around among providers or get an expert to point you in the right direction to get a WAN link with the characteristics needed for your application to work at peak performance. Price says that where multiple carriers are involved say one in Australia, another handling international traffic and the third within the US or Europe its important to ensure that the different classes of service are correctly aligned for optimum performance. In particular, real time traffic must be kept in the top class all the way through the infrastructure. CompressionYoure always going to have a bandwidth limitation, says Wastie. Changes such as the perceived need for disaster recovery, ever growing Power. Point decks and the tension between increasingly distributed staff and increasingly centralised infrastructure soak up previously spare bandwidth, while locations in rural areas and hard to service facilities such as oil rigs will always have limited bandwidth. Where this is the problem, compression could be the answer. Modern compression algorithms, including those used by Peribit and Packeteer, are able to recognise patterns in very large data streams perhaps weeks apart. This gives better results than traditional algorithms that use a limited window, perhaps as small as 1. Mbit of data. Compression is actually a combination of compression and caching, says Owen. He says Packeteer uses four different algorithms to suit the requirements of different applications. Iti Fitter Books Pdf. For example, file transfers can benefit from relatively slow but thorough compression, while packets for a transactional application should be handled as fast as possible. Having TCP rate control and the level of compression handled by one appliance by far provides the best value in terms of optimising the network, says Owen. The functions can work against each other if they are separated, and the most aggressive application will still win. Correctly implemented, compression can increase the throughput as much as fourfold, he says. Protocol acceleration.
