Efficient many-to-many real-time communication using an intelligent Ethernet switch

An Expansion Method of Reliable Data Transmission of the Short-Message Communication on Satellite Network

“…The highest digit of header in last block is set to 1, which identify the end of data pack. (11) Calculate a new block by carrying bitwise exclusive XOR operation on data blocks of which the marking number are in the range of 1 to n, and then we mark this new block as Num.0 block.…”

“…The process removes all the header of blocks, and combines all the blocks in the order of marking number from 1 to n. The integrated package is recovered. (11) Check if the data pack has been compressed. The process check if the data pack has been compressed.…”

“…[9,10] includes a bandwidth reservation scheme inside the switches without any hardware or operating system modification. Support for periodic real-time traffic on an extended switched Ethernet network, using earliest deadline first (EDF) scheduling, have been reported in [11]. A thin software layer is added between the Ethernet protocols and the TCP/IP suite in the end stations.…”

“…The switch is responsible for admission control where the feasibility analysis is made for each link and direction between the end nodes and the switch. More results on establishing real-time channels in packet switched networks and using deadline sorting in the switch to gain real-time support have been presented in [12].…”
