Dynamic Network Traffic Rerouting

RFT image

Laboratory: National Security Agency (NSA)

Technology: Network Traffic Rerouting

Opportunity: The NSA’s network traffic rerouting technology is currently at the mid-stage of development. A technical briefing is available upon request.

Details: This technology calculates a new shortest path in a network, allowing administrators to take advantage of underused links more effectively and reduce the network congestion experienced by users.

The invention has applications for providing services in networks such as MultiProtocol Label Switching (MPLS) and Generalized MPLS/Automatically Switched Optical Networks (ASON), which are governed by protocols such as the Open Shortest Path First-Traffic Engineering (OSPF-TE) and Resource Reservation Protocol (RSVP).

Benefits: Advantages of the network traffic rerouting technology include lower operating costs, more effective administration, faster performance, and system integration with existing infrastructures.


  • Wireless MESH networks
  • MultiProtocol Label Switching (MPLS)
  • Automatically Switched Optical Networks (ASON).
