Chapter Synopsis

Networked applications, particularly servers, must often process requests concurrently to meet their quality of service requirements. Chapter 5 describes general design tradeoffs related to concurrency alternatives. This chapter presents an overview of the synchronous event demultiplexing , multiprocessing, multithreading, and synchronization mechanisms available to implement those designs. We also discuss common portability and programming problems that arise when networked applications are developed using native C-level concurrency APIs.
