Network Traffic Control

The Network Traffic Control mechanism controls the level of UDP packets generated by the system. It
regulates a set of queuing systems and mechanisms by which UDP packets are received and transmitted
to the network router.
During a conference blast-out UDP packets can cause overloads on the network. MCU bandwidth usage
can increase to above the designated conference participant line rate settings, causing network bandwidth
issues such as latency and packet loss.
Three Network Traffic Control Flags are used to control the Network Traffic mechanism:
● ENABLE_TC_PACKAGE -
When the flag is set to NO (default), Network Traffic Control is disabled on the Collaboration Server.
Set the flag to YES to enable Network Traffic Control.
● TC_BURST_SIZE -
This flag regulates the Traffic Control buffer or max burst size as a percentage of the participant line
rate. In general, higher traffic rates require a larger buffer. For example, if the flag is set to 10 and the
participants line rate is 2MB, then the burst size is 200Kbps.
Default = 10
Flag range: 1-30.
● TC_LATENCY_SIZE -
This flag limits the latency (in milliseconds) or the number of bytes that can be present in a queue.
Default = 500
Flag range: 1-1000 (in milliseconds).
SIP Proxy Failover With Polycom® Distributed Media
Application™ (DMA™) 7000
Collaboration Server systems that are part of a RealPresence DMA system environment can benefit from
the RealPresence DMA system's SIP Proxy Failover functionality.
SIP Proxy Failover is supported in the RealPresence DMA system's Local Clustering mode with redundancy
achieved by configuring two DMA servers to share a single virtual IP address.
The virtual IP address is used by the Collaboration Server as the IP address of its SIP Proxy.
