Abstract: A route for a data unit through a network may be defined based on a number of next hops. Exemplary embodiments described herein may implement a router forwarding table as a chained list of references to next hops. In one implementation, a device includes a forwarding table that includes: a first table configured to store, for each of a plurality of routes for data units in a network, a chain of links to next hops for the routes; and a second table configured to store the next hops. The device also includes a forwarding engine configured to assemble the next hops for the data units based on using the chain of links in the first table to retrieve the next hops in the second table and to forward the data units in the network based on the assembled next hops.

Abstract: A network device receives a packet with a multicast nexthop identifier, and creates a mask that includes addresses of egress packet forwarding engines, of the network device, to which to provide the packet. The network device divides the mask into two portions, generates two copies of the packet, provides a first portion of the mask in a first copy of the packet, and provides a second portion of the mask in a second copy of the packet. The network device also forwards the first copy of the packet to an address of a first egress packet forwarding engine provided in the first portion of the mask, and forwards the second copy of the packet to an address of a second egress packet forwarding engine provided in the second portion of the mask.

Abstract: A network device may receive user datagram protocol (UDP) packets associated with an internet protocol (IP) session. The network device may apply a first firewall filter by setting one or more bits of each UDP packet to particular bit values to allow each UDP packet to be identified in association with the first firewall filter. The network device may update, each time a UDP packet is received, a first packet counter to account for a total number of UDP packets to which the first firewall filter has been applied. The network device may provide each UDP packet to another network device. The other network device may update a second packet counter. The network device and the other network device may provide the first packet counter and the second packet counter to a server device to cause the server device to determine packet loss information for the IP session.
