The Phoebus project seeks to encourage a paradigm shift in the way traditional edge and backbone networks are utilized in order to improve end-to-end throughput over long distances. By augmenting the current Internet model with an additional service layer, Phoebus embeds "intelligence" in the network that allows a connection to become articulated and adapt to the environment on a segment by segment basis. The system includes a protocol and software infrastructure that addresses many of the fundamental issues in long distance data movement and allows the Internet infrastructure to evolve.

  • Allows existing applications to utilize dynamic circuit allocation with no changes.
  • Allows adaptation to segment-specific transport protocols.
  • Automatically improves end-to-end performance without extensive host tuning.


  • Phoebus is based on the Logistical Session Layer, an old page is here
