  • Patent number: 8537840
    Abstract: In one embodiment, an angular distance calculation technique may enable an intermediate node, such as a route reflector, to render customized best path selection decisions to destination address prefixes and advertise those decisions to its intermediate peering nodes, i.e., route reflector clients, in an autonomous system of a computer network. That is, the route reflector may execute a routing protocol, such as BGP, to select and advertise a next hop (e.g., an address prefix of an egress point of the autonomous system) associated with a customized best path to a route reflector client based on an angular distance between the route reflector client and the egress point. In this manner, the route reflector client may route data traffic destined to a destination address prefix utilizing the egress point associated with the customized best path to that prefix.
