> --------------------------------------------------

> Key: DISPATCH-169
> URL: https://issues.apache.org/jira/browse/DISPATCH-169
> Project: Qpid Dispatch
> Issue Type: Sub-task
> Components: Router Node
> Reporter: Ted Ross

>
> The current router design does message routing synchronously with the receipt of delivered messages. The proposed improvement will put a FIFO for deliveries on the incoming links (only for links used for message-routing, not routed-links). This has the following benefits:
> - A credit loop can be established for the producer such that back-pressure prevents the FIFO from exceeding a defined limit.
> - Messages that cannot be routed, or that are lost due to topology change can be resent from the ingress link without the involvement of the attached client.
> - Routing can be moved to a single thread thus eliminating lock contention on the route table.
