Troubleshooting and Understanding Cisco Gatekeeper Bandwidth Management
Available Languages
Contents
Introduction
This document assumes the reader is familiar with a basic comprehension of Cisco IOS® Software Gatekeepers and Gatekeeper to Gateway H.225 Registration, Admission, and Status (RAS) Messagings. Refer to Understanding H.323 Gatekeepers for more information.
According to the H.323 recommendation, Cisco IOS Gatekeepers should support these H.225 RAS bandwidth management messages:
-
Bandwidth Request (BRQ)
-
Bandwidth Rejection (BRJ)
-
Bandwidth Confirmation (BCF) messages
This concept can be based on bandwidth management. It can also be a null function that accepts all requests for bandwidth changes. In other words, the Gatekeeper can either use these messages to manage bandwidth if it allows or rejects requests or just ignore them.
Bandwidth Management Operation Overview
The Cisco Gatekeeper can reject calls from a terminal due to bandwidth limitations. This can occur if the Gatekeeper determines that there is not sufficient bandwidth available on the network in order to support the call. This function also operates during an active call when a terminal requests additional bandwidth or reports a change in bandwidth used for the call.
The Cisco Gatekeeper maintains a record of all active calls so that it can manage the bandwidth resources in its zone. In a cluster configuration, the Gatekeeper Update Protocol (GUP) announcement indication message is exchanged every set interval of time and carries information about the bandwidth utilization for the zone. This GUP message exchange allows the alternate Gatekeepers in order to properly manage the bandwidth for a single zone, even though the Gatekeepers are in separate physical devices.
When you decide whether there is enough bandwidth in order to accept a call Admission Request (ARQ), the Cisco Gatekeeper calculates the available bandwidth with this formula:
Available_bandwidth = (total_allocated_bandwidth) - (bandwidth_used_locally) - (bandwidth_used_by_all_alternates).
If the available bandwidth is sufficient for the call, an Admission Confirmation (ACF) is returned, otherwise an Admission Rejection (ARJ) is returned.
Voice gateways should consider codec, Layer 2 encapsulation, and compression features such as compressed RTP [cRTP] when they request bandwidth from the Cisco Gatekeeper. Sometimes these features are not defined at the time of call setup, in which case a bandwidth change request can be issued to the gatekeeper after call setup in order to adjust the amount of bandwidth the call uses.
Note: As of Cisco IOS Software Release 12.2(2)XA, Cisco has implemented only the functionality of the report of any Bandwidth changes when Codecs change. See the section: How BRQ is Triggered from the Gateway to Notify the Gatekeeper to Reduce Call Bandwidth for more information.
How to Configure the Bandwidth Management Feature on the Cisco Gatekeeper
As of Cisco IOS Software Release 12.3(1), these types of zone bandwidth limitations can be configured on the Cisco Gatekeeper:
-
The maximum bandwidth for all H.323 traffic between the local zone and a specified remote zone. If desired, this configuration can be repeated individually for each remote zone.
-
The maximum bandwidth allowed for a single session in the local zone, typically used for video applications, not for voice
-
The maximum bandwidth for all H.323 traffic allowed collectively to all remote zones
-
The new command bandwidth check-destination checks the destination endpoint bandwidth before it responds to ARQ. This command was introduced in Cisco IOS Software Release 12.3(1).
Use these commands in order to configure Cisco Gatekeeper zone bandwidth:
-
bandwidth {interzone | total | session} {default | zone zone-name} max-bandwidth
-
bandwidth remote max-bandwidth
-
bandwidth check-destination
Refer to the bandwidth command for more details.
These configured values are used in order to process ARQs and BRQs.
For an ARQ, the Cisco Gatekeeper deducts the bandwidth specified in the message from the appropriate zone counters and/or remote counters. If this causes any counter to go negative, then the call is denied and an ARJ response is sent with the reason ARJ_REQ_DENIED. If the call request exceeds this bandwidth, then the Cisco Gatekeeper returns an Admission Rejection (ARJ).
When a BRQ requests a bandwidth increase, the Cisco Gatekeeper validates the request against the zone and/or remote. If the validation fails, then a BRJ response is sent with a reason of BRJ_INSUFFICIENT_RSC and the maximum amount of bandwidth allowed.

Bandwidth Related RAS Messages (BRQ/BCF/BRJ)
The BRQ message is used in order to request a change in bandwidth from the Cisco Gatekeeper. This is the procedure:
-
The Cisco Gatekeeper verifies the request by the endpointIdentifier in order to locate the endpoint in the registration database.
-
It locates the call record through the use of the callReferenceValue in order to find a call associated with the endpoint with the same callReferenceValue.
-
If it locates the call record, it then computes the change in bandwidth, then adds or subtracts from the global zone bandwidth, as necessary. It does the same for any proxy or gateway resources in use.
-
A BCF or BRJ message is sent back to the endpoint, which depends on success or failure.
RAS Messages Used to Report Bandwidth Status
The Information Request Response (IRR) "Non-Standard Data" field also carries information about the current used bandwidth on a gateway or proxy.
How BRQ is Triggered from the Gateway to Notify the Gatekeeper to Reduce Call Bandwidth
Prior to Cisco IOS Software Release 12.2(2)XA on the Cisco H.323 Gateway, calls were always reported in order to require a bandwidth of 64 kbps. This is the unidirectional bandwidth for a Cisco G.711 codec. If the endpoints in the call chose to use a more efficient codec, this was not reported to the Cisco Gatekeeper. In the Cisco IOS Software Release 12.2(2)XA version of the Cisco H.323 Gateway or later, which conforms with H.323 version 3, the reported bandwidth is bidirectional. Initially, 128 kb is reserved. If the endpoints in the call select a more efficient codec, the Cisco Gatekeeper is notified of the bandwidth change.
Note: Configure the Cisco H.323 Gateway with this command in global configuration mode in order to use the reported bandwidth behavior used prior to Cisco IOS Software Release 12.2(2)XA for zone bandwidth management:
Router(config-gateway)#emulate cisco h323 bandwidth
Examples
This section covers these two examples:
Example 1: Bandwidth Management in a Cluster Topology
See the debugs captured from a Cisco Gatekeeper in a cluster. The debug shows the ARQ and ACF messages, which includes the bandwidth required for the call. After you receive these messages, the Cisco Gatekeeper updates the other gatekeepers in the cluster about this bandwidth change.
Note: These commands are used in order to capture this output: debug h225 asn1, debug ras, debug gatekeeper gup asn1, debug gatekeeper gup events.

Example 2: Use BRQ in Order to Report Bandwidth
Find debugs from a Cisco Gatekeeper in a setup where the bandwidth on the remote gatekeeper is limited to 144 kbps. You see in the debug that the ARQ requested is an initial bandwidth of 128 kpbs. When the call is set up, the endpoint reports the change in the bandwidth with a BRQ message and the bandwidth used in 16 kpbs, which means the call was set up with Cisco G729 codec. Then another call is requested and is treated the same.
Note that if the second call arrived before the endpoint requested the change in bandwidth for the first call, the Cisco Gatekeeper rejects that call, since 128+128=256 kpbs and that is more than 144 kpbs configured.
