Link Monitoring: A Comprehensive Guide to Network Optimization
Links are the plugs, sockets, cables, and electrical signals traveling through a network. Every link implies a function. At the hardware level, electronic signals activate functions; data are read, written, transmitted, received, checked for error, etc. At the software level, instructions activate the hardware (access methods, data link protocols, etc.). At higher levels, the data transferred or transmitted may request functions to be performed (client/ server, program-to-program, etc.).
