The Diameter Signaling Controller Old Wine in a New Bottle?
Since the advent of switches in telecommunication networks, there has been the need for a way to ‘signal’ the switch to appropriately route the call. In the early days this was done in-band along with the ‘voice path’. However, that was very slow and resource intensive, so in the 1970’s the researchers at Bell Laboratories came up with the brilliant idea to separate the voice and the signaling network. This led to the growth of the signaling network, a low-capacity, low-latency and high-speed network exclusively for sending signaling traffic.
