Current Internet transports conflate transport semantics with endpoint addressing and flow regulation, creating roadblocks to Internet evolution that the authors propose to address with a new layering model. Factoring endpoint addressing (port numbers) into a separate Endpoint Layer permits incremental rollout of new or improved transports at OS or application level, enables transport-oblivious firewall/NAT traversal, improves transport negotiation efficiency, and simplifies endpoint address space administration. Factoring congestion control into a separate Flow Layer cleanly enables in-path performance optimizations such as on satellite or wireless links, permits incremental rollout of new congestion control schemes within administrative domains, frees congestion control evolution from the yoke of "TCP-friendliness," and facilitates multihoming and multipath communication.
