摘要： A method, network device, and computer readable medium are disclosed. In one embodiment of the method, a data packet is received at a node within a first segment routing enabled access network. The first access network is connected, via a first area edge node, to a first area of a subdivided segment routing enabled network, and a specified destination for the data packet is reachable via a second segment routing enabled access network connected to the subdivided network. The method embodiment further includes receiving from a centralized controller a remote segment identifier stack, where the remote segment identifier stack encodes a path extending from the first area edge node to the second access network. The embodiment of the method continues with encapsulating the data packet with a full segment identifier stack comprising the remote segment identifier stack, and forwarding the encapsulated data packet toward the first area edge node.

摘要： A method, apparatus and memory for forwarding packets through a network domain containing nodes that are label distribution protocol (LDP) enabled and nodes that are segment routing (SR) enabled. In one embodiment, the method may include receiving at a hybrid node a packet with an attached segment identifier and detaching the segment identifier from the packet. This embodiment of the method continues with attaching a first LDP label to the packet after the segment identifier is detached and forwarding the packet with the attached first LDP label on a path toward a first LDP enabled node.

摘要： A method and apparatus for switching a data packet between a source and destination in a network. The data packet includes a header portion and a data portion. The header portion includes routing information for the data packet. The method includes defining a data path in the router comprising a path through the router along which the data portion of the data packet travels and defining a control path comprising a path through the router along which routing information from the header portion travels. The method includes separating the data path and control path in the router such that the routing information can be separated from the data portion allowing for the separate processing of each in the router. The data portion can be stored in a global memory while routing decisions are made on the routing information in the control path.

摘要： A method and apparatus for in-line processing a data packet while routing the packet through a router in a system transmitting data packets between a source and a destination over a network including the router. The method includes receiving the data packet and pre-processing layer header data for the data packet as the data packet is received and prior to transferring any portion of the data packet to packet memory. The data packet is thereafter stored in the packet memory. A routing through the router is determined including a next hop index describing the next connection in the network. The data packet is retrieved from the packet memory and a new layer header for the data packet is constructed from the next hop index while the data packet is being retrieved from memory. The new layer header is coupled to the data packet prior to transfer from the router.

摘要： A method for providing an early packet termination such that prior to the complete transmission of the number of cells specified in the first cell of a packet, a crossbar connection is released. The act of releasing the connection is triggered on recognition of an End of Packet bit (EOP) set in any cell of the stream. The feature can be enabled, for example, by a specific act of setting a register bit, connecting a pin to Vcc or ground or some other intentional act. The feature will default to the inactive state upon reset.
