Several current (e.g. TCP/IP, UDP/IP, SCTP/IP) and future (SONATE, NENA) service providers offer similar communication functionality but differ in quality on a variety of important criteria. As the number of service providers increases, the need to select the best service based on criteria for certain application requirements is increasing.
