A.2 Proof of Theorem 10.2
Let the new session request arrive at the admission scheduler at time t during group
v new =
tG
/
T F
. Then due to clock jitter, the current group at other servers can range from
. To guarantee that the assigned group has not started in
any of the servers implies assigning a group larger than the largest current group in any of
the servers, i.e. s new =
( t
τ
) G
/
T F
to
( t
+ τ
) G
/
T F
( t
+ τ
) G
/
T F +
1. Applying the inequality
x
+
y
x
+
y
we
have
s new
tG
/
T F + τ
G
/
T F +
1
(10.51)
Substituting into
v new we have s new v new + τ
G
/
T F +
1 and the results follows.
