Abstract:
1. A method of routing data packets in a high-speed access network infrastructure having a plurality of intermediate servers, and at least one managed access point router that interfaces with a plurality of service networks, which are external to the high-speed access network infrastructure, the method comprising: providing the plurality of intermediate servers to route local and non-local data packets within the high-speed access network infrastructure using only destination-based packet forwarding; providing the at least one managed access point server to receive only non-local packets from the plurality of intermediate servers and to route the non-local data packets to the plurality of service networks using only source address-based policy routing; assigning a network address to a customer of the high-speed access network infrastructure, the network address based on a subscription of the customer to a service network, wherein the address is assigned from a list of network addresses that are dynamically allocated only to customers of the high-speed access network infrastructure that are subscribers of the service network; receiving a local data packet from the customer at one of the plurality of intermediate servers; forwarding the local data packet within the high-speed access network infrastructure using only destination-based packet forwarding; receiving a non-local data packet from the customer at one of the plurality of intermediate servers; forwarding the non-local data packet to a managed access point router using only destination-based packet forwarding; receiving the non-local data packet at the managed access point router; comparing a source address of the non-local data packet to the list of network addresses; and forwarding the packet to a router in the service network only when the source address matches a network address from the list.
