Thanks for the update. We had a mini design summit on ECS last week. The plan is to have a running version in two weeks. Given your questions, it is a good idea that we write down the design soon so that we can all work together.
@Shu/Junzhuo: I believe that you are leading the ECS design. Can you write down the discussion soon so that we can discuss with Tamim and others.

Could you please advise me if I have understood ECS correctly?
I was told, in the first step, we calculate the shortest hop-count assuming that the link metric is 1. Do we just implement a shortest-path algorithm for the topology graph based on the data from TopologyManager?
Next step is to figure out a natural interface, in ODL, to configure link metrics and compute routing cost. Do we design a YANG model to configure link properties (link cost metrics)? Currently I don't see link properties (such as delay, bandwidth) in NodeConnector or TopologyUserLinkConfig. Am I missing anything? Do we have to design a data structure to store the cost metric for each link?
Which version of ODL do I look into? I don't see TopologyManager code in the Lithium release. I only see the class files. Am I missing anything? However I see the TopologyManager in Hydrogen release.
Looking forward to your suggestions.
