Hi Med,

Couple of Nits:

1)
OLD:
Likewise, 'sid' value is=09
monotonically increased by the DOTS client for each configuration=09
session, attackers replaying configuration requests with lower=09
numeric 'sid' values will be rejected by the DOTS server if it=09
maintains a higher numeric 'sid' value for this DOTS client.

NEW:
Likewise, 'sid' value is=09
monotonically increased by the DOTS client for each configuration=09
request, attackers replaying configuration requests with lower=09
numeric 'sid' values will be rejected by the DOTS server if it=09
maintains a higher numeric 'sid' value for this DOTS client.

2)
Define 'idle' time (i.e. when no attack traffic is present).
