简介

本文假设读者熟悉思科IOSï ¿  ½软件网守和网守基本理解对网关H.225注册、接纳和状态(RAS)消息传送。有关详细信息,请参阅了解 H.323 网守

根据H.323建议, Cisco IOS网守应该支持这些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

此概念可以根据带宽管理。它可以也是接受所有要求带宽更改的零函数。换句话说,网守能任一使用这些消息管理带宽,如果准许或拒绝请求或者忽略他们。

带宽管理操作概述

Cisco网守能拒绝从终端的呼叫由于带宽限制。这能发生,如果网守确定没有在网络的充足的带宽联机为了支持呼叫。当终端请求额外的带宽或报告在用于呼叫时的带宽上的一个变化此功能也运行在激活的呼叫期间。

Cisco网守保持所有激活的呼叫记录,以便能管理带宽资源在其区域。在集群配置中,关守升级协议(GUP)通知指示消息被交换每个集合间隔时间并且传播关于带宽利用率的信息区域的。此GUP消息交换允许备选网守为了适当地管理单区域的带宽,即使网守在独立的物理设备。

当您决定是否有足够的带宽为了接受呼叫许可请求(ARQ), Cisco网守计算与此公式的可用的带宽:

Available_bandwidth = (total_allocated_bandwidth) - (bandwidth_used_locally) - (bandwidth_used_by_all_alternates)。

如果可用的带宽为呼叫是满足的,接纳确认(ACF)返回,否则准入拒绝(ARJ)返回。

当他们请求带宽从Cisco网守时,语音网关应该考察编码、第2层封装和压缩功能例如压缩RTP [cRTP]。有时这些功能没有在呼叫建立时定义,在带宽更改请求可以发出到网守情况下,在呼叫建立为了调节呼叫使用的相当数量带宽后。

注意: 自Cisco IOS软件版本12.2(2)XA,当编码更改时, Cisco实现所有带宽更改报告的仅功能。请参阅部分:BRQ如何从网关被触发通知网守减少呼叫带宽欲知更多信息。

如何配置在Cisco网守的带宽管理功能

自Cisco IOS软件版本12.3(1),区域带宽限制的这些类型在Cisco网守可以配置:

  • 所有H.323流量的最大带宽本地区域和一个指定的远程区域之间。如果需要,此配置可以为每个远程区域单个被重复。

  • 为单个会话允许的最大带宽在本地区域,典型地使用视频应用,不语音

  • 集体所有H.323允许的流量的最大带宽到所有远程区域

  • 在响应对ARQ前, new命令带宽检查目的检查目的地端点带宽。此命令在Cisco IOS软件版本12.3(1)介绍。

请使用这些命令为了配置Cisco网守区域带宽:

  • 带宽{区域之间|总计|会话} {默认|区域区域名称}最大带宽

  • 带宽遥控最大带宽

  • 带宽检查目的

    欲了解更详细的信息参考bandwidth命令

这些配置值用于为了处理ARQ和BRQs。

对于ARQ, Cisco网守从适当的区域计数器和远程计数器扣除在消息指定的带宽。如果这导致其中任一与相反去负值,则呼叫拒绝,并且ARJ答复用原因ARJ_REQ_DENIED传送。如果呼叫请求超出此带宽,则Cisco网守返回准入拒绝(ARJ)。

当BRQ请求带宽增加时, Cisco网守验证请求区域和远程。如果验证发生故障,则BRJ答复用BRJ_INSUFFICIENT_RSC原因和允许的最大带宽量传送。

网守显示用于的命令显示带宽信息

输入show gatekeeper zone status命令为了显示所有区域的带宽信息。

带宽相关的 RAS 消息 (BRQ/BCF/BRJ)

BRQ消息用于为了请求在带宽上的一个变化从Cisco网守。这是程序:

  1. Cisco网守由endpointIdentifier验证请求为了找出在注册数据库的终端。

  2. 它通过使用callReferenceValue查出呼叫记录为了查找呼叫关联与终端与同样callReferenceValue。

  3. 如果它查出呼叫记录,然后计算在带宽上的变化,则从全局区域带宽添加或减少,如所需要。它为所有代理或网关资源执行同样在使用中。

  4. BCF或BRJ消息被退还的对终端,取决于成功或失败。

用于报告带宽状态的 RAS 消息

信息请求响应(IRR) " Non-Standard Data "字段也传播关于当前使用的带宽的信息在网关或代理。

BRQ 是如何从网关被触发以通知网守减少呼叫带宽

在Cisco H.323网关的Cisco IOS软件版本12.2(2)XA之前,呼叫总是报告为了要求带宽64 Kbps。这是思科G.711编码的单向的带宽。如果在呼叫的终端选择使用更有效的编码,这未报告给Cisco网守。在Cisco IOS软件版本12.2(2)XA. Cisco H.323网关或者以后版本,遵守H.323版本3,报告的带宽双向。最初, 128 kb保留。如果在呼叫的终端选择更有效的编码, Cisco网守通知带宽更改。

注意: 配置Cisco H.323网关同此in命令全局配置模式为了使用在Cisco IOS软件版本12.2(2)XA之前使用的报告的带宽行为区域带宽管理:

Router(config-gateway)#emulate cisco h323 bandwidth

示例 1:带宽管理在集群结构里

请参阅从集群的一个Cisco网守捕获的调试。调试表示ARQ和ACF消息,包括为呼叫要求的带宽。在您收到这些消息后, Cisco网守更新在集群的其他网守关于此带宽更改。

示例 2:请使用BRQ为了报告带宽

查找从一个Cisco网守的调试在远程关守的带宽对144 Kbps被限制的设置的。您在调试看到ARQ请求的是起始带宽128 kpbs。当呼叫设置时,终端报告在带宽上的变化与BRQ消息,并且用于16 kpbs的带宽,含义呼叫设置思科G729编码。然后另一呼叫请求和被处理同样。

请注意,如果第二次呼叫到达了,在终端请求在带宽上的变化第一个呼叫的前,呼叫,因为128+128=256 kpbs,并且是超过配置的144 kpbs的Cisco网守拒绝。
