Abstract: A software agent generates packet sessions and hands off the task of generating and routing the packets to a programmable hardware logic block, such as a packet processor. The software agent provides entries in one or more tables that are subsequently used by the packet processor to generate and route the packets. During a first stage, the packets are generated at an ingress pipeline. The packets are then transferred to an egress pipeline from which pipeline the packets are reinjected back into the ingress pipeline. During the second stage and at the ingress pipeline, routing information, representative of a network layer or a tunnel, to which the packets are to be routed, are added to the packets. The packets are then forwarded to the egress pipeline and subsequently routed to a next hop or tunnel leading to the packets' respective destination addresses.

Abstract: A method and apparatus of a network element that keeps a port of the network element up in a split port configuration is described. In an exemplary embodiment, the network element receives an indication of a link loss on a receive interface of the port, wherein the port includes the receive interface and a transmit interface. In addition, the receive interface is coupled to a first device over a first link, and the transmit interface is coupled to a second device over a second link. Furthermore, the network element performs an operation of the port such that a link coupled to a transmit interface of the port remains up. The network element additionally suppresses receive faults that are received on the receive interface.
