父子对等组之间的关系

遇到一个问题：超级结点和边缘结点都加入对等组P
超级结点在对等组P中启动汇聚服务
边缘结点连接到超级结点

此时边缘结点（创建）加入P的子对等组C

问题：超级结点是否有必要也创建或加入对等组C
以保证边缘结点在对等组C中的通信

No. RDVs are scoped per peergroup. This means that
if you create a sub-peergroup this group can have
a new set of rendezvous that are indepent of the
NetPeergroup (root peergroup) RDVs. While your
peer connect to the sub-group RDVs, it will remain
connected to the NetPeerGroup RDVs. You can
explore this within the JXTA shell using the
chpgrp command to switch the peergroup context and
check the output of the "rdvstatus" command.

For the NetPeergroup you want to be an
edge, for the remaining sub-peergoups you should
let your peer (if you have good connectivity) dynamically
act as a RDV via the auto-RDV election
option.
