Joel,

For your last unresolved comment, the following text is added to explain the 
TN-1 in the Figure 1:

“Figure 1 below shows an example of a portion of workloads belonging to one 
tenant (e.g., TN-1) are accessible via a virtual router connected by AWS 
Internet Gateway; some of the same tenant (TN-1) are accessible via AWS vGW, 
and others are accessible via AWS Direct Connect. The workloads belonging to 
one tenant can communicate within a Cloud DC via virtual routers (e.g., vR1, 
vR2).”

Thank you.

Linda

Figure 1 in section 4.1 could use some clarification.  It is unclear if the two 
TN-1 are the same networks, or are intended to be different parts of the tenant 
network.  And similarly for the two TN-2.  It is also unclear why the top 
portion is even included in the figure, since it does not seem to have anything 
to do with the data center connectivity task?  Wouldn't it be simpler to just 
note that the diagram only shows part of the tenant infrastructure, and leave 
out irrelevancies?
[Linda] The two TN-1 are intended to be different parts of one single tenant 
network.  Is adding the following good enough?
“TN: Tenant Network. One TN (e.g., TN-1) can be attached to both vR1 and vR2.”
<jmh>While that at least makes meaning of the figure clear, I am still left 
confused as to why the upper part of the figure is needed.</jmh>
<ld> mainly to show that one Tenant can have some routes reachable via Internet 
GW and others reachable via Virtual GW (IPsec). And routes belonging to one 
Tenant can be connected by vRouters </ld>
<jmh2>You may want to think about ways to better explain your point, since I 
missed it. </jmh2>
