Abstract:

A method is provided for allocating bandwidth to a subscriber in a service provider domain that is part of a packet switched network such as the Internet, for example. In accordance with the method, a number of shares of bandwidth are assigned to the subscriber based on an agreement between the subscriber and a service provider. A subscriber identifier and the number of shares assigned thereto are distributed to the routers in the domain of the service provider. The routers will in turn allocate bandwidth to packets they receive based on the number of shares assigned to the subscriber transmitting or receiving the packet. The subscriber may include one or more different user terminals that aggregate traffic onto a single datastream. The shares assigned to the user may denote absolute amount of bandwidth, or alternatively, may denote a relative bandwidth allocation.

Abstract:

In an arrangement where a plurality of cache servers are interconnected to form a virtual cache, each cache server includes a selection module and a caching module. The selection module determines whether the cache server can service an incoming request for information, whether the request ought to be directed to another one of the cache servers, or whether the request be routed to the site from whence the information is requested. In making this determination, in accordance with one embodiment, the module consults a table that associates sites or/and sub-sites with specific ones of the cache servers. In another embodiment, the determination is made by translating the address of the site, or sub-site, or web page that is requested; for example, with a hash function. The caching module determines whether a request for information from a particular site will be cached in the cache server of the caching module, if it is not already being cached by one of the cache servers. The determinations made by the caching module comport with the determinations made by the selection module.
