Abstract:  As Internet traffic becomes increasingly diverse, comprising such applications as online gaming, high-definition video streaming, VOIP, and videoconferencing, the proportion of real-time traffic to elastic traffic (such as text and static images) continues to increase. It is almost a tautology to discuss the continuing exponential increase in Internet traffic, as well as the importance of Internet access to daily life. Currently the Internet provides limited capability to adapt to current multimodal network requirements, not to mention increased demand. Internet routing is based on a best-effort, single-shortest-path, destination-based paradigm, which inherently restricts the ability to accommodate heterogeneous Quality of Service (QoS) needs and the ability to take full advantage of network capacity.

We introduce the partially ordered Internet--a conceptually new way of looking at Internet routing. The partially ordered Internet could provide QoS solutions and increased network capacity naturally and automatically. Changing Internet routing to a partially-ordered paradigm could enable true, multi-metric, multiple-path Quality of Service routing. We take the first step towards implementing this new paradigm by determining the properties required to guarantee that partially ordered, multiple metric forwarding paths are guaranteed best and loop-free.
