Title: Transmission failure recovery system in multicast transmission
Inventor: YAMADA NOBUAKI
IPC: H04L12/18
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To eliminate deviation of an information image between sending and receiving ends in a multicast transmission. SOLUTION: A sending end 1 adds a transmission number n to transmission information and sends it to receiving ends 1A, 2B,... Each receiving end holds a received transmission number n as the previous transmission number (n-1), compares the current transmission number with the previous one, decides it as normal receiving if they are continuous and updates an information image (entire) with the transmission information. When transmission numbers are not continuous, a receiving end decides them as abnormal receiving, the receiving end that decides them as abnormal receiving sends an image matching request to a sending end. The sending end receives the request and sends the latest information image to the receiving end that makes the request.  The receiving end that makes the request receives the latest information image and updates an information image (entire) which is held by the receiving end.
