A constant-time method for TCP/IP socket I/O multiplexing
Jianli Sun · International Journal of Critical Computer-Based Systems · 2011
For a given large number of N communication channels or sockets, the major challenge with I/O multiplexing is to frequently find out which R channels are ready for input and output. The computational cost of I/O multiplexing is high, and it is directly proportional to N . This paper presents an innovative method to complete TCP/IP multiplexing functionality for any number of N sockets in a small constant time.
