Optimizing multihomed ISP links

Organizations that need true high availability will find that multihoming ISP links alone will not be sufficient. They will still have to deal with link performance issues. As most organizations have already realized, adding additional bandwidth will not adequately solve the problem. Rather, it creates an endless cycle of buying extra bandwidth while receiving diminishing benefits. To add to the problem, organizations are experiencing extraordinary demand for bandwidth in an effort to deliver new IP services, without being able to affordably and effectively manage the bandwidth.

It is important to find a balance, without having to make a tradeoff between the deployment of applications and efficiently using bandwidth. The challenge comes in being able to easily manage multiple WAN links based on bandwidth costs, capacity and application usage, as well as to incrementally add bandwidth when needed to support appropriate levels of capacity. The following are two common issues to consider:

1. Prioritizing applications

IT departments continually grapple with how to affordably and efficiently prioritize various types of traffic going across their WAN network. They often have a mix of applications, some of which are bandwidth-friendly, while others hog bandwidth and degrade performance. They need a way to prioritize traffic based on the application type, user, location and link, in order to ensure that high-priority applications will always get the bandwidth they need.

2. Oversubscribing bandwidth

IT departments are continually faced with limited bandwidth capacity. Naturally, as bandwidth levels become insufficient, the performance of the applications begins to diminish. This invariably lowers user productivity and can adversely affect business revenue. IT organizations are also dealing with diverse client types (that is, PDAs, cell phones, laptops, etc.) accessing their sites. They require a bandwidth management capability that allows them the flexibility and ease-of-use to set policies to enable the appropriate levels of bandwidth to meet the needs of these diverse client devices.
