摘要:
In general, techniques are for providing a direct forwarding path between virtual routers within a single virtualized routing system. In one example, a method includes combining forwarding information from a plurality of virtual routers into collapsed forwarding information that comprises one or more direct forwarding paths between the respective virtual routers. The method also includes determining a direct forwarding path to an egress interface of the second virtual router, in response to receiving a network packet at an ingress interface of a first virtual router. The method also includes forwarding the network packet from the ingress interface of the first virtual router to the egress interface of the second virtual router using the direct forwarding path, wherein the network packet traverses a switch fabric directly from the ingress interface of the first virtual router to the egress interface of the second virtual router.

A device may reserve a slot for a received packet in a packet ordering queue (POQ), convey the packet to one of a plurality of threads for processing, obtain the packet from the one of the plurality of threads after the packet has been processed, organize the packet in the POQ in accordance with a position of the reserved slot, and release the packet from the POQ if the reserved slot is a head of the POQ.

A system determines a scheduling value based on a current length of a downstream queue in a network device. The system sends the scheduling value from the downstream queue to an upstream queue and schedules dequeuing of one or more data units, destined for the downstream queue, from the upstream queue based on the scheduling value.
