Abstract:
A method implemented in a network element to determine an autonomous system (AS) path pre-pending (ASPP) vector for an AS of the network element that accounts for AS business relationship induced policies and global impact of ASPP decisions by using comparable paths between AS in a network for application of network management strategies, the comparable paths grouped by path types defined by local preference polices, the method including gathering AS level topological data for the network, categorizing AS link relationships in the topological data, computing the comparable paths for each AS pair, and applying any one of a load balancing process, back-up path provisioning process or traversal avoidance process to the comparable paths to determine an ASPP vector for the AS of the network element.
