....delay and any buffer size. Two conventional analytical methods are compared with our methods. Comparison results show that our methods are more accurate. 1. Introduction Generally the throughput analysis for pure SR ARQ focuses on infinite buffer case or just provide lower bound on throughput [1 2 3 4]. In finite case the buffer size is mostly assuming to be times of packets numbers W , which is the packets permitted to be transferred in a roundtrip time [1, yI The performance for SR ARQ with different buffer appeared for the first time in [1] The performance anal sis is based on an inferior ....

The performance anal sis is based on an inferior s stem that gives a lower bound performance. Weldon presents an optimum SR ARQ scheme in [4] Pure SR ARQ is a special case of the scheme. There are also man variations of the optimum scheme [5] The performance is also anal zed based on a lower ....

....For the purpose of retransmission a selective retransmission strategy seems appropriate. Although a go back n mechanism requires very simple functionality on the part of receivers, namely no packet resequencing ability, it wastes bandwidth and increases the total transfer time in a WAN environment [17]. For multicast sessions a packet lost at a router may not be received by a subset of receivers. Hence the packet has to to be retransmitted to these receivers. There are three ways in which a lost packet may be 1 Hybrid schemes are possible where a NACK based scheme is augmented with a polling ....

.... at very high channel error rates appears very interesting [10, 11, 12, 13, 14] A significant amount of work has been done on hybrid ARQ FEC schemes using both convolutional coding and sequential decoding [15, 16, 17, 18] This paper follows the line of research that was opened up by Yu and Lin [19, 20], and by Wang and Lin [21] This line is characterized by a scheme that uses two linear codes C 0 and C 1 where C 0 is an (n; k) error detecting code and C 1 is a (2n; n) half rate invertible code, designed for error correction only. The two half codewords produced by C 1 are alternatively used ....

....processing from the rate of the channel. Selective repeat, 7,8,9] while providing improved performance, is more complex to implement, particularly in terms of memory management at the receivers since packets may arrive, and will be accepted, in any order. Many modifications have been proposed [10,11,12] to make the SR protocol feasible, but it does not appear that any lends itself to simple hardware implementation. The idea in this paper is simple. The receiver function in Go back N is easy to implement in hardware. Replicating the hardware two or more times (for example, having two FIFO buffers ....
