[chord] Number of nodes in a Chord ring?

[Hai Dao Le]

Hi,

How to know the exact number of nodes in a Chord ring? I am running
Chord in my slice which includes all nodes in Planetlab. If I use
"devel/vis", I see the number is about 250. If I use "devel/walk", the
number of nodes is different for each node I point to (some node reports
75, another: 190, another: 315, ...). Which method is more correct? Is
there another way?

Thanks in advance,

Hai
