One of the problems with convergence is protocol, starting with IP.

While we tend to think in terms of Internet and IP, there are alternatives. Dedicated circuits come to mind, followed by frame relay. One option that hasn't gotten much exposure but may offer some real advantages is gigabit Ethernet via fiber optics. The fiber overcomes the distance limitations associated with Ethernet. Ethernet allows for layer 2 switching versus IP based routing. From a private network perspective, this may be an ideal way of lowering overheads and improving latency and jitter issues.

The same applies to other transports such as a private radio network. The IP headers are only one solution to source and destination, and are necessary only when joining the public Internet where IPv4 is the required protocol by agreement (not technical requirement). In 1985, the choice of protocol was still being debated, and Ethernet and Token Ring were still fighting for dominance.

Moving out of IP opens up other opportunities for improved performance and efficiency in other applications besides voice.

Anyone using a Layer 2 Ethernet carrier willing to share their experiences?

Anyone interested in assistance in finding providers may PM me for specifics.
