I looked at the document and there are a few very basic things I
wanted to state that need to be added:

1. There needs to be a capability exchange from the Execution node to
the Manager node.
2. Scalability issues will occur if keepalives all go to the manager
node. In my view there can be a heirarchy of keepalives.
3. There should be a heirarchy of manager nodes too, considering the
number of Execution nodes that need to be managed. So there should be
a messaging exchange allowed between Manager and Manager node.
4. All TLV and headers should have length of 16 bits atleast. 8 bits
is not scalable at all with the amount of information that is there.
5. There needs to be authentication in the packets to provide some security.
6. There needs to be async messaging allowed both from server to
client and client to server.
7. There is already a PCE framework that exists. We need to look at
it. It is used for simialr purposes in a TE network.
