Upgrading HiPath 3000
9.2.3.2 Additional System Load
Overview
Activation of the Signaling & Payload Encryption feature has the following consequences for
the HiPath network:
● Higher bandwidth requirement due to continuous TLS sessions for:
– Connections to HFA terminals (CorNet-IP TC/TS, H.225 CS)
– Connections for SIP terminals (SIP including SDP)
– H.323 and SIP trunking connections
● Higher bandwidth requirement:
– Due to the fill and authentication algorithms used by TLS during transmission of user
data
– Due to the proprietary encryption protocols used for IPDA and CTI connections
– Due to SRTP/SRTCP
● Higher network traffic due to periodic downloads of CRL ( Certificate Revocation List) or
delta CRL by each Gateway
● Higher network traffic due to recently introduced protocols
– H.235 Annex D for DMC Slave connections
– MIKEY messages
● Additional data due to protocol extensions:
– CorNet-TC/TS plus X messages
– H.225 RAS (LEGK communication)
–CorNet NQ
Because of the many configuration options and scenarios possible, it is difficult to accurately
determine the effects of this feature on the system, that is, the additional bandwidth require-
ment and the increased data traffic volume. The following sections are intended as suggestions
on how to calculate the additional system load.
