Research Contributions
Dr. Jain is the co-inventor of the DEC-bit scheme for congestion avoidance in computer networks which has been adapted for implementation in Frame Relay networks as forward explicit congestion notification (FECN), ATMAsynchronous Transfer Mode
Asynchronous Transfer Mode is a standard switching technique designed to unify telecommunication and computer networks. It uses asynchronous time-division multiplexing, and it encodes data into small, fixed-sized cells. This differs from approaches such as the Internet Protocol or Ethernet that...
Networks as Explicit Forward Congestion Indication (EFCI), and TCP/IP networks as Explicit Congestion Notification
Explicit Congestion Notification
Explicit Congestion Notification is an extension to the Internet Protocol and to the Transmission Control Protocol and is defined in RFC 3168 . ECN allows end-to-end notification of network congestion without dropping packets. ECN is an optional feature that is only used when both endpoints...
