Client-Server Design Issues

Threads in Distributed Systems

  • Multithreaded clients
    • Thread can block waiting for server response but application/process is not blocked
  • Multithreaded servers
    • Simplified server code as opposed to finite-state-machine approach that users non-blocking system calls
    • Can handle multiple client requests in parallel (while making blocking ystem calls)
    • Improved performance over iterative servers on multiprocessor systems
