Abstract	We propose BANANAS a connectionless framework for both intra domain and inter domain tra c engineering TE in the Internet The key contributions of this framework are a it allows the source to discover multiple paths and decide on how to split tra c among paths assuming simple for warding extensions in a subset of routers b it does not require signaling or high per packet overhead c it enables an incremental upgrade strategy for both intra domain OSPF and inter domain BGP routing to support TE capabilities d in a fully upgraded network every source can control how tra c is mapped to paths and therefore network wide tra c engineering objectives can be achieved A path to a destination address is parsimoniously speci ed in a xed length PathID eld in the packet header PathID is the sum of link weights on the path or the sum of Autonomous System AS numbers for inter domain paths This encoding allows e cient connectionless for warding without using a signaling protocol We describe extensions to OSPF and BGP to support the proposed framework We propose a simple multi path computation algorithm under partial upgrade assumptions discuss traf c splitting techniques and forwarding extensions An ns based simulation is used to demonstrate the framework and performance improvements
