This document discusses Tunneling, Compressing and Multiplexing Traffic Flows (TCM-TF) to more efficiently transport real-time traffic like voice and online games. It notes the inefficiency of tiny payload packets for these services. TCM-TF aims to compress and multiplex these packets to save bandwidth. It describes applying TCM-TF in multi-domain, single-domain and private scenarios. The technique uses header compression, multiplexing and tunneling layers with different options on each layer. Evaluations show TCM-TF can save over 50% bandwidth for voice calls and up to 30% for online games. Related links provide more details on TCM-TF drafts, publications and mailing list.
Influence of the Distribution of TCRTP Multiplexed Flows on VoIP Conversation...Jose Saldana
This document describes an experiment to evaluate the impact of different Tunneling Compressed RTP (TCRTP) multiplexing schemes on voice quality over IP (VoIP) under varying network conditions. The experiment multiplexed VoIP packets using TCRTP tunnels with different numbers of flows and measured the resulting voice quality using the R-factor metric. With a high-capacity router buffer, all TCRTP schemes showed step-like quality degradation as background traffic increased. With a time-limited buffer, smaller tunnels led to smoother quality decline. More flows per tunnel reduced overhead and allowed higher background traffic levels before quality dropped.

This article explores the possibility of using traffic optimization techniques within the context of the LISP (Locator/ Identifier Separation Protocol) framework. These techniques use Tunneling, Multiplexing and header Compression of Traffic Flows (TCMTF) in order to save bandwidth and to reduce the amount of packets per time unit. Taking into account that encapsulation is necessary in LISP, bandwidth can be drastically reduced in flows using small packets, which are typical of many real-time services. The ability of the LISP framework to manage the signaling of TCMTF options is also studied. An analytical expression of the savings, as a function of the different header sizes, is devised and used to calculate the maximum expected savings. Different services and scenarios of interest are identified, and this allows the consideration of tests with real traffic traces, showing the savings as a function of the multiplexing period, and demonstrating that the additional delays can be acceptable for real-time services.
