ASON dial-up requirements
Control plane network resilience
- Should not have dependencies of signaling network with transport network
- Allows for re-use of signaling network for control of other transport networks – GMPLS principle
- Signaling network fail should not impact existing connections
- E.g., RSVP control plane failure would tear down existing connections?
Scheduled connection services
- Support for scheduled connection by different means
- Scheduling provided by user scheduler – no need for signaling
- Scheduling provided by service provider scheduler – signaling needed
- Have we discussed and examined these different aspects
- E.g., if service provider ? how to guarantee scheduled connection when network is composed of non-deterministic connection requests?
