Description
The traffic shaping function estimates the
parameters of the incoming traffic. If the incoming
traffic exceeds the defined parameters, Branch
Gateway can drop the packets or mark them as
low-priority.
Branch Gateway can map several PPP sessions to
a single E1/T1 interface.
–
–
Enables full 2.048 Mbps bandwidth usage.
Supported over channelized, fractional, or unframed
E1/T1 ports or over a Universal Serial Port
interface.
The following Frame Relay LMI types are
supported:
• ANSI (Annex D)
• ITU-T:Q-933 (Annex A0)
• LMI-Rev1
• No LMI
Supported between any type of Serial Layer 2
interface.
Dynamic CAC provides enhanced control over the
WAN bandwidth. When Dynamic CAC is enabled on
an interface, Branch Gateway tells the MGC to
block calls when the interface bandwidth is
exhausted.
Branch Gateway uses Weighted Fair VoIP Queuing
(WFVQ) as the default queuing mode for WAN
interfaces. WFVQ combines weighted fair queuing
(WFQ) for data streams and priority VoIP queuing to
provide real-time responses required for VoIP.
Branch Gateway also supports the VoIP Queue and
Priority Queue legacy queuing methods.
