    摘要： The invention discloses a system, a method and a device for service switching. According to the invention, the terminal device accesses multiple services via one service access point. A service switching entity is arranged to a common network element and has further access to service providers and other service access entities. The service access entity dynamically exchanges service access information with other service access entities. After resolving the access to the desired service, the service access entity dynamically exchanges the state of the service providers. Based on the exchanged information, the service access entity applies a routing algorithm that determines the route to the desired service.

    摘要： A method and a system for managing a TCAM table are disclosed. A new route is inserted into the TCAM table at an available location using an index. The new route is added into a Patricia tree organized by a mask length associated with the new route. Routes having common prefixes with the new route are searched for in Patricia trees organized by longer mask lengths and in Patricia trees organized by shorter mask lengths to locate a chain for the new route. The chain for the new route groups routes having common prefixes. The routes in the chain are sequenced in an order of longer prefix first such that a route at a top of the chain has a longest prefix. A swap of routes in the chain is performed to accommodate the new route and to maintain the longer prefix first order.
