Hi, Tony:
Would you like to elaborate this in more detail to show how you design the
control plane hierarchically but the traffic can be transported horizontally?
Let’s consider the following graph:
If, as you stated, we connect R1 and R7 via one link(although we will not do
so, if
Hi Tony,

data plane is necessarily hierarchical.
Since Aijun posted his question I was trying to think of such model, but
failed.
While it is easy to envision this with DV protocols say BGP - do you have
any pointer to

Well, given that we’re talking a link state protocol running SPF over a
database in O(n log n) time, it’s pretty clear that we don’t want to

Some comments on this draft:
1. The size of network is increasing, but it is becoming more flat. Is it the
right direction to make the network more hierarchical?
2. More hierarchical network means the traffic will also be traversed in
hierarchical way, is it more efficient?
3. Is there any
