Packets are routed from at least one internet protocol (IP) address in accordance with border gateway protocol (BGP); while carrying out the routing in accordance with the border gateway protocol (BGP), at least one border gateway protocol (BGP) attribute associated with the at least one internet protocol (IP) address is noted. A firewall policy is applied to the packets from the at least one internet protocol (IP) address based on the at least one border gateway protocol (BGP) attribute associated with the at least one internet protocol (IP) address. Techniques may be implemented, for example, on a router or on a separate firewall device coupled to a router.

Firewall access control with border gateway protocol attributes

A replicator is configured to be coupled to a first packet-based network, and a packet analysis module and a router are coupled to the replicator. The router is configured to be coupled to a second packet-based network. The replicator receives packets from the first packet-based network, passes the packets to the router, and passes a copy of the packets to the packet analysis module. The packet analysis module identifies, in a set of customers of the second packet-based network, a top usage subset. The top usage subset includes those of the customers who are using more bandwidth of the second packet-based network than other ones of the customers. The top usage subset includes at least two of the customers. The packet analysis module identifies, at an entry point of the second packet-based network, routes of packets destined for the top usage subset. The router discards a predetermined percentage of the packets destined for the top usage subset. The predetermined percentage is determined in order to reduce bandwidth utilization of the second packet-based network by a desired amount. The predetermined percentage is identical for all of the customers in the top usage subset.

Destination based methodology for managing network resources

A system and method for providing premium transport in a DOCSIS-compliant cable network. An edge server in a DOCSIS-compliant cable network maintains a list of preferred content providers (PCPs). For each PCP, the PCP list comprises matching criteria. The edge server monitors the header of incoming packets for the matching criteria. A packet that matches the matching criteria is modified by the edge server causing the packet to be associated with a 'premium' downstream service flow. Packets sent in response to a 'preferred' packet are parsed by a cable modem and routed upstream according to a &#x201c;premium&#x201d; upstream service flow.
