METHOD FOR OPERATING A MEMORY BUFFER SYSTEM IMPLEMENTED AT A SENDER STATION FOR THE FAST DATA TRANSPORT OVER A COMMUNICATION NETWORK, CORRESPONDINGLY ADAPTED APPARATUS TO PERFORM THE METHOD, COMPUTER PROGRAM PRODUCT, AND COMPUTER PROGRAM
The invention relates to a method for operating a memory buffer system for the fast data transport over a communication network (30) with a reliable transport protocol working in a point-to-multipoint data transfer mode in a multi-thread environment. The invention proposes a novel meta-storage in-memory organization, which enables that concurrent memory accesses could be guaranteed without using locks, such as mutexes or semaphores. The meta-storage organization involves the use of ActiveCellsBeginDescr- and Active CellsEndDescr-descriptors and the addition of mask information (MASK) for each cell reflecting for the receiving stations (21, 22, 23) of a data transfer session in the point-to-multipoint mode, the state whether or not an acknowledgment message has been received back from the respective receiving station (21, 22, 23) for the corresponding data packet being sent over the communication network (30). The invention also proposes an enhanced ACK ARQ loss report method.
