Hi Adrian,


===

Section 2.2 has

   An E-Tree service has one or more Root ACs and many Leaf ACs.

I suggest that "many" is not a necessary part of the definition although it may be probable in deployments. For the definition I think you need:

   An E-Tree service has one or more Root ACs and at least one Leaf AC.
[Lucy] Since one key of E-tree service is prohibiting the communication between leaf ACs. Therefore, one leaf AC case does not make sense. How about: An E-Tree service has one or more Root ACs and at least two Leaf ACs.

Section 2.3.1 para 2

s/fame/frame/
[Lucy] will change it. Thanks.

Figure 1 shows two notations "E-Tree". The associated arrows do not make it clear what is the extent of the E-tree since the top one and the bottom one show different edge points. Can you tidy that up?
[Lucy] I'll fix it.

Regards,
Lucy
