本文档假设读者熟悉Cisco IOS®软件网守和网守对网关H.225注册、准入和状态(RAS)消息的基本理解。有关详细信息,请参阅了解 H.323 网守。
根据H.323建议,Cisco IOS网守应支持以下H.225 RAS带宽管理消息:
带宽请求(BRQ)
带宽拒绝(BRJ)
带宽确认(BCF)消息
此概念可以基于带宽管理。它也可以是一个空函数,接受所有带宽更改请求。换句话说,如果网守允许或拒绝请求或仅忽略请求,则可以使用这些消息管理带宽。
由于带宽限制,思科网守可以拒绝来自终端的呼叫。如果网守确定网络上没有足够的可用带宽来支持呼叫,则可能会发生这种情况。当终端请求额外带宽或报告用于呼叫的带宽变化时,此功能也在活动呼叫期间运行。
思科网守维护所有活动呼叫的记录,以便管理其区域中的带宽资源。在集群配置中,网守更新协议(GUP)通告指示消息每隔设置的时间间隔交换一次,并传送有关该区域的带宽利用率的信息。此GUP消息交换允许备用网守正确管理单个区域的带宽,即使网守位于单独的物理设备中。
当您决定是否有足够的带宽来接受呼叫准入请求(ARQ)时,Cisco网守使用以下公式计算可用带宽:
Available_bandwidth =(total_allocated_bandwidth)-(bandwidth_used_locally)-(bandwidth_used_by_all_all_alternates)。
如果可用带宽足以用于呼叫,则返回准入确认(ACF),否则返回准入拒绝(ARJ)。
当语音网关向Cisco网守请求带宽时,应考虑编解码器、第2层封装和压缩功能,如压缩RTP [cRTP]。有时,在呼叫建立时未定义这些功能,在这种情况下,在呼叫建立后可以向网守发出带宽更改请求,以调整呼叫使用的带宽量。
注意:自Cisco IOS软件版本12.2(2)XA起,思科仅实施了编解码器更改时任何带宽更改报告的功能。请参阅部分:如何从网关触发BRQ以通知网守减少呼叫带宽以获取详细信息。
自Cisco IOS软件版本12.3(1)起,可在Cisco网守上配置以下类型的区域带宽限制:
本地区域和指定远程区域之间所有H.323流量的最大带宽。如果需要,可以为每个远程区域单独重复此配置。
本地区域中单个会话允许的最大带宽,通常用于视频应用,而不是语音
所有H.323流量允许到所有远程区域的最大带宽
新命令bandwidth check-destination在响应ARQ之前会检查目的终端带宽。此命令在Cisco IOS软件版本12.3(1)中引入。
使用以下命令配置Cisco网守区域带宽:
bandwidth {interzone |总计 | session} {default | zone zone-name}最大带宽
bandwidth remote max-bandwidth
bandwidth check-destination
有关详细信息,请参阅bandwidth命令。
这些配置的值用于处理ARQ和BRQ。
对于ARQ,Cisco网守从相应的区域计数器和/或远程计数器扣除消息中指定的带宽。如果这导致任何计数器变为负数,则呼叫被拒绝,并且ARJ响应被发送,原因为ARJ_REQ_DENIED。如果呼叫请求超过此带宽,则Cisco网守返回准入拒绝(ARJ)。
当BRQ请求带宽增加时,思科网守根据区域和/或远程验证请求。如果验证失败,则发送BRJ响应,原因是BRJ_INSUFFICIENT_RSC和允许的最大带宽量。
输入show gatekeeper zone status命令以显示所有区域的带宽信息。

BRQ消息用于请求从Cisco网守更改带宽。这是程序:
Cisco网守通过endpointIdentifier验证请求,以便在注册数据库中查找终端。
它通过使用callReferenceValue查找呼叫记录,以便查找与具有相同callReferenceValue的终端关联的呼叫。
如果找到呼叫记录,则会计算带宽变化,然后根据需要从全局区域带宽中添加或删除带宽。它对任何正在使用的代理或网关资源都执行相同操作。
BCF或BRJ消息将发回终端,具体取决于成功或失败。
Information Request Response(IRR)“Non-Standard Data”字段还传送有关网关或代理上当前已使用带宽的信息。
在Cisco H.323网关上的Cisco IOS软件版本12.2(2)XA之前,始终会报告呼叫,以便需要64 kbps的带宽。这是Cisco G.711编解码器的单向带宽。如果呼叫中的终端选择使用更高效的编解码器,则不会向Cisco网守报告。在符合H.323版本3的Cisco IOS软件版本12.2(2)XA或更高版本的Cisco H.323网关中,报告的带宽是双向的。最初,保留128 kb。如果呼叫中的终端选择更高效的编解码器,则Cisco网守会收到带宽更改通知。
注意:在全局配置模式下使用此命令配置Cisco H.323网关,以便使用在Cisco IOS软件版本12.2(2)XA之前使用的报告带宽行为进行区域带宽管理:
Router(config-gateway)#emulate cisco h323 bandwidth
本节介绍以下两个示例:
请参阅从集群中的Cisco网守捕获的调试。调试显示ARQ和ACF消息,包括呼叫所需的带宽。收到这些消息后,思科网守会更新集群中其他网守关于此带宽更改的信息。
注意:以下命令用于捕获此输出:debug h225 asn1、 debug ras、 debug gatekeeper gup asn1、 debug gatekeeper gup events。

在远程网守的带宽限制为144 kbps的设置中,从思科网守查找调试。您在调试中看到,ARQ请求的初始带宽为128 kpbs。呼叫建立后,终端会报告带有BRQ消息的带宽变化和16 kpbs中使用的带宽变化,这意味着呼叫是使用Cisco G729编解码器建立的。然后请求另一个呼叫,并得到相同的处理。
请注意,如果第二个呼叫在终端请求更改第一个呼叫的带宽之前到达,则思科网守会拒绝该呼叫,因为128+128=256 kpbs且配置的带宽大于144 kpbs。
