[RPRWG] Merits of Open Loop
Folks,
As some people are busy doing simulations and writing proposals for the
San Jose meeting, I am posting this presentation early on the
reflector. It describes the merits of open loop congestion controls and
may impact some of the simulation scenarios that would be presented.
The main conclusions of the document are that:
- Congestion avoidance algorithms may lead to static partitioning of the
ring bandwidth between high and low priority traffic
- With CA it may not be possible to bound the ring access delay of high
priority traffic
- Open loop does not suffer from HOL blocking
- Open loop has relatively low configuration and operational complexity
- Open loop is not prone to tuning issues, or link aggregation, etc...
Regards, Siamack
