2. Mesh Routing in IEEE

3. Comment
The concept of partial and multiple topology server needs be described in more detail

4. Suggested Remedy
Combine the subclause into the subclause and

5. Resolution (1) 6.5.2.1 Topology server 6.5.2.2 Link state registration
Allow every MPNC to serve as a local topology server, which provides the optimal route between two any source-destination pairs on the subtree consisting of its descendant MPNCs only
Link state registration
Register link state information at the ancestor MPNCs
A link cost table constructed at each MPNC
Update the routing table by Dijkstra’s algorithm
Route establishment
Optimal route is provided by the common ancestor which is closest to both the source and destination MPNCs
Route discovery/notification/formation

6. Resolution (2) Some options
Not all MPNCs necessarily operate as topology servers
The depth of subtree may be set to a certain value to limit the amount of link state information maintained by the MPNC

7. Examples Server routing with the aid of MC
Server routing without the aid of MC
