Abstract
A method is provided of reducing traffic in or relating to a service provider network. The service provider network comprises a core packet network, a plurality of first access points () off the core network to an external packet network (), and a plurality of second access points () off the core network to local subscribers. A cache (T1, T2) is provided at each of the access points () for caching content passing through. In response to a request received from the external network () at any of the first access points () for content from a local subscriber, it is attempted to serve the request from content previously cached at that first access point () or another of the first access points (). If unable to serve the request from any of the first access point caches (T1), it is attempted to serve the request from content previously cached at the second access point () serving the local subscriber. If unable to serve the request from that second access point cache (T2) then the request is forwarded to the local subscriber.
