QoS
The purpose of the Enterprise Edge QoS module is to set priorities for IP traffic and
to assign quality of service levels to critical applications and IP telephony.
The Enterprise Edge QoS module serves two primary purposes:
In a DiffServ network, QoS acts as an edge device and performs the packet
classification, marking, and prioritizing.
In a non-DiffServ or legacy network, QoS manages the WAN link bandwidth to
make sure critical voice (and optional video) packets get high priority when
crossing the slow WAN link in both directions.
Relationship between the QoS Module and the VoIP QoS Monitor
The VoIP gateway in Enterprise Edge includes a VoIP Quality-of-Service (QoS)
Monitor that periodically monitors the delay and jitter of IP networks between two
peer gateways by using a proprietary protocol. These monitoring packets are
delivered at UDP port 5000.
The mainobjective of the VoIP QoS Monitor is to allow new VoIP calls to fall back
to the PSTN if the IP network is detected as “bad”.
The QoS module discussed here complements the VoIP QoS Monitor. While the
VoIP QoS Monitor passively monitors the IP network, the QoS module actively
improves the IP network by giving VoIP packets higher priority to travel so that the
chance for the VoIP QoS Monitor to detect the connection as “bad” is reduced.
Note: For a VoIP call, if a packet passes the VoIP QoS Monitor but fails the QoS
admission control, it is delivered over IP but only as a best-effort flow.
There is no fallback to PSTN if a packet has passed the VoIP QoS Monitor
checking.
VoIP QoS Monitor packets travel at the same priority as VoIP packets, which is at
higher priority than normal IP packets. If VoIP packets travel at a premium level
but VoIP QoS Monitor packets travel at normal best-effort level, it is possible for
the VoIP QoS Monitor to report the IP network as “bad” and start fallback to the
PSTN, but the actual delay and jitter for VoIP packets are still “good” since VoIP
packets have a higher priority. To avoid this, add UDPport 5000 to the high priority
queue in all routers.
