INTER-PROVIDER NETWORK ARCHITECTURE

摘要

An inter-provider network architecture system is disclosed. In particular, the system may enable a service provider network and a partner network to take advantage of each other's network cores, such that the resources of the service provider network and the partner network may be more effectively utilized to service customers of both networks. By doing so, not only can the service provider network and the partner network take advantage of each other's network resources, but they can also give each other's customers broader network reach into regions that are not typically serviced by their own networks. The service provider network may effectively accomplish this by providing a limited view of the service provider network to the partner network, or vice versa, so that traffic and data can flow between the networks without each network having to be fully aware of each other's entire network topologies.

主权项

1. An inter-provider network architecture system, comprising:
a service provider core router in a service provider network that performs operations, comprising:
transmitting an advertisement of a loopback of a service provider exchange point in the service provider network to a partner provider core router in communication with a partner provider edge router in a partner network; andtransmitting a cost metric associated with reaching the service provider exchange point in the service provider network to the partner network; and the service provider exchange point in the service provider network, wherein the service provider exchange point performs operations, comprising:
receiving an advertisement of a network prefix of a customer device in communication with a service provider edge router in the service provider network;transmitting the advertisement of the network prefix for the customer device with a label to a partner provider exchange point in the partner network, wherein the label identifies the service provider exchange point as a next hop, wherein the advertisement of the network prefix is transmitted to the partner provider edge router in the partner network; andreceiving traffic intended for the customer device if the cost metric indicates that the service provider exchange point is in a shortest path from the partner provider edge router in the partner network, wherein the traffic is received based in part on the advertisement of the loopback and the advertisement of the network prefix with the label.
