IDIPS: ISP-Driven Informed Path Selection

This draft describes a simple network-based protocol to facilitate Path Selection and to improve traffic engineering capabilities in multihomed corporate networks. With this protocol, any network device that requires to select a path among a list of different paths asks a Traffic Engineering service called IDIPS (ISP-Driven Informed Path Selection) to obtain an ordered list of the possible paths. The ordering is constructed according to policies and performance requirements of both the host and network provide
