Abstract:
A communication system for communication of data packets associated with a packet switched network, the system comprising:a remote access server comprising at least a host processor and a port processor, the port processor communicating the data packets to and from at least one communication device and at least one destination; a segmentation and reassembly device, the segmentation and reassembly device routing the data packets to and from the port processor and the at least one destination; and wherein, the host processor is coupled to the port processor and the segmentation and reassembly device and the port processor being coupled to the segmentation and reassembly device, the host processor establishing a virtual circuit between the port processor and the segmentation and reassembly device, the host processor further directing the port processor to communicate data packets to the segmentation and reassembly device via the virtual circuit, whereby the port processor and segmentation and reassembly device exchange data packets directly via the virtual circuit without per-packet handling by the host processor of all data packets provided on the virtual circuit, wherein the host processor does not process the data packets for the virtual circuit after the virtual circuit is established, wherein the virtual circuit includes a queue associated with the port processor, the queue being part of the segmentation and reassambly device.
