Lucent Technologies Release 8.2 Capacities and Performance, For C-LAN Number of Sockets Required

D Capacities and Performance

The following table gives the number of sockets (connections) needed for IP softphones and H.323 trunks.

For C-LAN		Number of Sockets Required
Number of sockets per	=	3 (1 DCP + 2 H.323)
road-warrior application		2 (1 DCP + 1 H.323 with tunneling)
(The H.323 sockets are held up
while registered if the endpoint is
administered as a Permanent user or
while the call is active if administered
as an As Needed user)
Number of sockets per	=	1 (while registered)
telecommuter application
Number of sockets per Native	=	1 per call with tunneling
Mode station		2 per call without tunneling
Number of sockets per H.323 Tie	=	sharing & tunneling: 1 /sig grp (default)
trunk		sharing, no tunneling: 1 /sig grp + 1/call
(the numbers depend on whether
signaling groups are shared by trunks		no sharing, tunneling: 1 /call
and whether tunneling is used)		no sharing, no tunneling: 2 /call
Number of sockets per H.323	=	2 (while on call)
DID trunk

As a worst-case example of these limits, assume 1000 active H.323 endpoints, each requiring 3 C-LAN connections and G.723 codec processing. This configuration would require 3x1000/508 = 6 C-LANS and 1000/22 = 46 MedPros.
