We consider a communication system in which a transmitter is connected to a receiver through parallel channels, and the Go-Back-N ARQ scheme is used to handle transmission errors. A packet error on one channel results in retransmission of packets assigned to other channels under the Go-Back-N...

The routing algorithm can be static or dynamic. The flow and congestion control in a datagram network typically use windows, as explained in Chapter 2. The windows may correspond to individual links or to end-to-end paths through the network. For instance, the HDLC (High-Level Data Link ...

writing generic algorithm (泛型编程) hiding implementation detail (隐藏具体实现)) providing interception points (提供拦截端点) writing generic algorithm 在Golang 中并不支持泛型编程。在 C++ 等高级语言中使用泛型编程非常的简单,所以泛型编程一直是 Golang 诟病最多的地方。
GC 会使用分布式终止算法(distributed termination algorithm)来检测何时不再有根标记作业或灰色对象,如果没有了 GC 会转为mark termination(标记终止); mark termination(标记终止) STW,然后将 GC 阶段转为 _GCmarktermination,关闭 GC 工作线程以及 mutator assists(协助线程); 执行清理,如 flush mcache; the sweep...
