The basic selective-repeat ARQ scheme can achieve very high throughput. However, it encounters a resequencing problem. We analyze the average resequencing delay approximately under the assumption that the arrivals of NAK's are totally independent of the past history of the system. And, we examine its characteristics from numerical examples.
