摘要： Systems and related methods are described for handling one or more resource requests. A protocol engine receives a resource request in accordance with a prescribed protocol, and a classification engine determines a desired class of service for the request. An analysis engine optionally analyzes the request, and, responsive thereto, determines a desired sub-class of service for the request. A policy engine then allocates a resource to the request responsive to one or both of the desired class of service, and the desired sub-class of service.

摘要： A network switch includes a first content addressable memory (CAM), a second CAM, a binding lookup table (BLT), and a packet manager. The BLT extracts two sets of header information from ingressing packets. The first set is applied the first CAM to retrieve a service policy index. The second set of header information is applied to the second CAM to determine whether a connection already exists. If a connection exists, a flow transmission control block (fTCB) pointer is retrieved from the second CAM. Otherwise, if there is no current connection for the packet, a check is made of the service policy index to determine the level of service associated with the packet. Based on the assigned service level, a new fTCB pointer is retrieved, or alternatively, client and server TCB pointers are retrieved. The packet manager then processes the packet according to which TCB pointer is retrieved.
