             Summary: Initial load of topology page fetches too much information
                 Key: DISPATCH-543
                 URL: https://issues.apache.org/jira/browse/DISPATCH-543
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Console
            Reporter: Ernest Allen
            Assignee: Ernest Allen


As the topology graph is created, several entities for each router are fetched:
- .connection
- .router.link
-  .router
- .router.node
For large numbers of routers this takes a while.

Break up the creation of the topology graph. The routers and their connections to other routers can be generated using only .connection information. 

.router-link is used:
- to draw the small client circles. After the initial graph is drawn, go back and fetch the .router.link info for any router that has connections that are not "inter-router". 
- to display the popup when a client is clicked. This can quickly be fetched for the individual router when one of it's clients is clicked.
- to display the cross-section popup. This can be fetched when needed.

.router.node is used to generate the highlight line between routers. This entity can be fetched when needed.

.router is used when adding a new node. This can be fetched when needed.
