However, bandwidth capping is only one of many techniques used to reserve bandwidth for mission-critical applications. Two alternatives are (1) increasing the total amount of bandwidth, and (2) denying access to particular Internet servers. The first method is quite simple - network administrators merely obtain a higher-bandwidth link, effectively increasing the total available to all network applications. The second method, also known as ``banning'' particular Internet sites, is similar to connection-based bandwidth capping in that it restricts low-priority network traffic; however, instead of just limiting the bandwidth allocated for these connections, it prohibits any connection from the network to those servers. In other words, this is essentially a connection-based cap in which the bandwidth limit for low-priority connections is set to zero. For example, many universities have implemented bans on a popular music file-sharing service which, because of its popularity among college students, consumes a majority of the universities' available bandwidth [2]. By explicitly denying access to this service, the university can be absolutely sure that the service will no longer hinder its mission-critical network applications. While both of these alternatives are often used to reserve bandwidth for high-priority applications, bandwidth capping offers an equally effective solution with less side-effects.
