故障排除和瞭解Cisco Gatekeeper頻寬管理
目錄
簡介
本檔案假設讀者對Cisco IOS®軟體閘道管理員和閘道管理員與閘道H.225註冊、准入和狀態(RAS)訊息之基本理解是熟悉的。有關詳細資訊，請參閱瞭解H.323網守。
根據H.323建議，Cisco IOS網守應支援以下H.225 RAS頻寬管理消息：
-
頻寬請求(BRQ)
-
頻寬拒絕(BRJ)
-
頻寬確認(BCF)消息
此概念可基於頻寬管理。它也可以是一個空函式，接受所有頻寬更改請求。換句話說，如果閘道管理員允許或拒絕請求，則可以使用這些消息來管理頻寬，或者直接忽略這些請求。
頻寬管理操作概述
由於頻寬限制，思科網守可以拒絕來自終端的呼叫。如果網守確定網路上沒有足夠的可用頻寬來支援呼叫，則會發生這種情況。當終端請求額外頻寬或報告用於呼叫的頻寬變化時，此功能也可在活動呼叫期間運行。
思科網守維護所有活動呼叫的記錄，以便管理其區域中的頻寬資源。在集群配置中，每設定的時間間隔交換網守更新協定(GUP)通知指示消息並攜帶關於區域的頻寬利用的資訊。此GUP消息交換允許備用網守正確管理單個區域的頻寬，即使網守在單獨的物理裝置中。
當您確定是否有足夠的頻寬來接受呼叫准入請求(ARQ)時，思科網守使用以下公式計算可用頻寬：
Available_bandwidth =(total_allocated_bandwidth)-(bandwidth_used_locally)-(bandwidth_used_by_all_alternates)。
如果可用頻寬足以進行呼叫，則返回准入確認(ACF)，否則返回准入拒絕(ARJ)。
語音網關向Cisco Gatekeeper請求頻寬時，應考慮編解碼器、第2層封裝和壓縮功能，如壓縮RTP [cRTP]。有時，這些功能在呼叫建立時沒有定義，在這種情況下，可以在呼叫建立之後向網守發出頻寬更改請求，以便調整呼叫使用的頻寬量。
註：自Cisco IOS軟體版本12.2(2)XA起，思科僅實現了在編解碼器更改時報告任何頻寬更改的功能。請參閱部分：如何從閘道觸發BRQ，以通知閘道管理員減少通話頻寬以瞭解詳細資訊。
如何在Cisco Gatekeeper上設定頻寬管理功能
自Cisco IOS軟體版本12.3(1)起，可以在Cisco Gatekeeper上設定以下型別的區域頻寬限制：
-
本地區域和指定遠端區域之間的所有H.323流量的最大頻寬。如果需要，可以為每個遠端區域分別重複此配置。
-
本地區域中單個會話允許的最大頻寬，通常用於影片應用，而不是語音
-
允許集中到所有遠端區域的所有H.323流量的最大頻寬
-
新命令bandwidth check-destination在響應ARQ之前檢查目標終端頻寬。此命令是在Cisco IOS軟體版本12.3(1)中匯入。
使用以下命令配置Cisco Gatekeeper區域頻寬：
-
bandwidth {interzone |總計 | session} {default | zone zone-name} max-bandwidth
-
bandwidth remote max-bandwidth
-
bandwidth check-destination
如需詳細資訊，請參閱bandwidth命令。
這些配置的值用於處理ARQ和BRQ。
對於ARQ，Cisco Gatekeeper從適當的區域計數器和/或遠端計數器扣除消息中指定的頻寬。如果這會導致任何計數器變為負值，則呼叫會被拒絕，並會傳送一個ARJ響應，原因為ARJ_REQ_DENIED。如果呼叫請求超過此頻寬，思科網守將返回准入拒絕(ARJ)。
當BRQ請求增加頻寬時，思科網守會根據區域和/或遠端驗證請求。如果驗證失敗，則傳送BRJ響應，原因為BRJ_INSUFFICIENT_RSC和允許的最大頻寬量。
用於顯示頻寬資訊的閘道管理員show命令
輸入show gatekeeper zone status命令以顯示所有區域的頻寬資訊。

頻寬相關RAS訊息(BRQ/BCF/BRJ)
BRQ訊息用於要求思科閘道管理員變更頻寬。程式如下：
-
思科網守通過端點識別符號驗證請求，以便在註冊資料庫中找到端點。
-
它通過使用callReferenceValue查詢呼叫記錄，以查詢與具有相同callReferenceValue的端點關聯的呼叫。
-
如果找到呼叫記錄，則它會計算頻寬的變化，然後根據需要新增或減去全域性區域頻寬。它對所有正在使用的代理或網關資源執行相同的操作。
-
將BCF或BRJ消息傳送回終端，這取決於成功或失敗。
用於報告頻寬狀態的RAS消息
Information Request Response(IRR)「Non-Standard Data」欄位還攜帶有關網關或代理上當前使用的頻寬的資訊。
如何從網關觸發BRQ以通知網守降低呼叫頻寬
在Cisco H.323網關上的Cisco IOS軟體版本12.2(2)XA之前，總是報告呼叫以要求64 kbps的頻寬。這是Cisco G.711編解碼器的單向頻寬。如果呼叫中的終端選擇使用更有效的編解碼器，則不會向思科網守報告此情況。在符合H.323版本3的Cisco H.323網關或更高版本的Cisco IOS軟體版本12.2(2)XA中，報告的頻寬是雙向的。最初，保留128 kb。如果呼叫中的終端選擇更有效的編解碼器，思科網守將收到頻寬更改通知。
注意：在全域性配置模式下使用此命令配置Cisco H.323網關，以使用報告在Cisco IOS軟體版本12.2(2)XA之前使用的頻寬行為進行區域頻寬管理：
Router(config-gateway)#emulate cisco h323 bandwidth
範例
本節涵蓋以下兩個範例：
範例 1：集群拓撲中的頻寬管理
檢視從集群中的思科網守捕獲的調試。調試顯示ARQ和ACF消息，包括呼叫所需的頻寬。收到這些消息後，思科網守會更新集群中其他網守關於此頻寬更改的資訊。

範例 2：使用BRQ報告頻寬
在遠端網守頻寬限製為144 kbps的設定中，從思科網守查詢調試。您在調試中看到，請求的ARQ的初始頻寬為128 kpbs。設定呼叫後，終端會通過BRQ消息報告頻寬的變化，並報告16 kpbs中使用的頻寬，這意味著呼叫是使用Cisco G729編解碼器設定的。然後請求另一個呼叫，並會同樣處理。
請注意，如果第二個呼叫在端點請求更改第一個呼叫的頻寬之前到達，思科網守將拒絕該呼叫，因為128+128=256 kpbs已配置大於144 kpbs。
