Abstract
An increasing number of computers and workstations will require data communications like that of LAN-LAN interconnections. The requirement for high end-to-end throughput will be satisfied by B-ISDN, in which the ATM technique is the key technology. In B-ISDN, user data is segmented into fixed-length short packets (cells) and transferred at very high speed. The greater the amount of user data to be transmitted at one time, the more efficient the transmission has to be. Efficient error recovery is needed for the higher transmission efficiency as well as for a shorter response time, which is also a key data communication requirement.
This paper describes the functions needed for data communication in B-ISDN and classifies the error recovery methods that can be used by the end-to-end protocol for data communication. A partial-frame retransmission scheme is proposed and its performance is compared to that for selective-frame retransmission from the viewpoints of implementation complexity, efficiency, total throughput, and cell-loss probability.
A functional block model for partial-frame retransmission is proposed and it is shown that partial-frame retransmission can be implemented with little addition to the model for selective-frame retransmission.
The evaluation results show that partial-frame retransmission can provide higher efficiency for a wide variety of parameter values compared with selective-frame retransmission. They also show that partial frame retransmission reduces the cell-loss rate to less than 10% of that for selective-frame retransmission. In particular, when the incoming traffic load is relatively high, the proposed partial-frame retransmission scheme can avoid the congestion that selective-frame retransmission allows.
