[RPRWG] Why is RPR better as layer 2 technology than ATM
I would like to see a summary of the capabilities that makes RPR a
better choice than ATM for layer 2...
I have listed the issues I believe is advantageous in the RPR
technology compared to ATM:
1. No signaling is required to set up a connection in a RPR network
(assignment of VCI and VPI identifiers in an ATM network).
2. Reuse of IPs interface to Ethernet/802.
3. Reuse of different Ethernet PHYs. Although this seems more like an
issue for completing the standard within the given time-line without
having to spend the time and money required to develop a new PHY. It
isn't possible for a RPR station to talk to an Ethernet station
without using some type of bridge/router station.
4. Layer 2 protection.
5. Spatial Reuse.
Best Regards
Fredrik
