Description

在集中管理网络中根据优先级发送带宽请求
技术领域
本发明一般涉及通过集中管理网络的视频、电话和数据系统，并且更具体地涉及请求带宽以供通过网络传输视频、电话和数据分组的领域。
背景技术
诸如电缆调制解调器、通过因特网协议的语音(VoIP)网关、媒体终端适配器(MTA)以及机顶盒之类的网络设备通常是到分组传送所需要的物理电话和/或视频装置的接口。当前，这些网络设备为连接到网络设备的电话、计算机或电视机所生成的视频、语音和数据分组提供服务质量(QoS)。
由于接入网络中的分组拥塞，QoS被用来为视频、语音和数据分组动态地创建传送保障。更具体地，QoS在集中管理的接入网络中被用来确保某些分组的低等待时间和有保证带宽。网络设备在发送分组之前从管理接入网络的设备请求带宽。因此，管理接入网络的设备根据所请求分组的优先级(即，所请求分组的QoS)来授予带宽。QoS优先级通常在从0至N的范围，其中，N指示最关键分组。然而，传统地，网络设备，例如电缆调制解调器、机顶盒、MTA等都在预定时段期间请求带宽，这导致带宽请求间的冲突。另外，所有网络设备在预定时段期间同时进行请求而不管优先级如何，从而使得优先级为N的请求可能与优先级低于或高于N的请求相冲突。因此，需要使得能够在集中管理的接入网络中根据请求的优先级来进行带宽请求以避免请求分组冲突的系统和方法。

具体实施方式
可以在宽带通信系统的背景中来理解本发明的优选实施例。然而，注意，本发明可以以许多不同形式来体现，并且不应当解释为局限于这里所阐述的实施例。因此，希望这里给出的所有示例是非限制性的，并且被提供用于辅助阐明对本发明的描述。
本发明致力于允许网络设备基于分组的QoS优先级来请求带宽的系统和方法。分组的QoS优先级主要是由网络运营商确定的，并且取决于许多变量，例如订户数目和网络中使用的装置。根据本发明，系统中的网络设备根据调度图(scheduling map)来请求带宽。调度图被下载到所有网络设备中，该调度图给出了在请求时段内用于请求与分组优先级相对应的带宽的具体时间。然后，各个网络设备查阅调度图以便确定请求时段期间中用于发送请求分组的具体时间。重要地，由于随后网络设备在请求时段的不同时间发送请求，因此消除了或者显著减少了冲突。另外，在不同时间期间针对关键优先级分组的带宽请求可以被成组在一起，以确保关键分组请求不与较低优先级的分组请求相冲突。
图1图示出了用于发送视频、语音和数据分组的集中管理接入网络。受管理的接入网络设备105负责提供设备之间的连接，所述设备提供了媒体、信令、配置(provisioning)和QoS。例如，呼叫管理服务器(CMS)110经由受管理的接入网络设备105接收作出呼叫的请求。CMS 110然后发起并处理与该呼叫有关的信号。电缆调制解调器终端系统(CMTS)115利用线缆数据服务接口规范(DOCSIS)协议来管理通过受管理的接入网络100的会话。CMTS 115负责确保网络100上的所有电缆调制解调器(CM)保持同步。通常，光学节点120接收从CMTS 115接收的光信号，并且将这些信号转换为电信号。可以存在数个光学节点，使数个CM组125、130、135耦合到这些光学节点之一的输出。示出了CM组135内的一个订户的示例。RF分路器145将向机顶盒150和电缆调制解调器155提供信号的下游信号分离开。机顶盒150可以连接到电视机或者用于显示视频/音频信号的其它观看设备。另外，机顶盒150可以包括发送反向分组的反向发送器或电缆调制解调器。电缆调制解调器155对提供给所耦合的电话和/或计算机的信号进行过滤。通常，所有网络设备150、155都具有允许在网络设备150、155与受管理的接入网络设备105之间交互地发送分组的双向能力。此外，如所提到的，这些分组中的一些具有取决于应用的关联QoS优先级。
图2是图示出QoS优先级示例的表。在此示例中，0优先级表示尽力而为(best effort)。这可以被保留用于因特网浏览。其它较低优先级包括可以用于标准或业务关键性分组的1-3。在此示例中，较高优先级是优先级4-6，其中，优先级4是用于流传输多媒体和语音的受控制负荷，优先级5用于视频(例如，交互式媒体)，并且优先级6用于语音呼叫。优先级7可用于保留流量。如所提到的，这些QoS优先级可由网络运营商来配置。
图3是由受管理的接入网络100内的设备采取的、用于请求带宽以发送分组的一连串步骤。在步骤305，CMTS 115分配预定时段供CM组125、130、135内的所有CM请求带宽。在此时间期间，在步骤310，准备发送与视频、语音和/或数据相关联的分组的每个CM发送表明与分组相关联的某种优先级的请求。如果来自一个CM的请求与来自另一CM的请求相冲突，则在步骤315，这两个CM在请求时段内根据内部算法躲避(back off)较短时间，以试图避免进一步的冲突。在躲避时间之后，这两个CM重新发送请求。在步骤320中，一旦CMTS 115接收到请求，CMTS 115就根据所指定的分组优先级向作出请求的CM分配带宽。例如，如果CM请求用于优先级为4的分组的带宽，则CMTS在向请求了用于具有优先级0的分组的带宽的CM分配带宽之前，为此CM分配带宽。
图4图示出了向受管理接入网络中的特定网络设备授予专用带宽的示例。为了避免分组冲突，一些运营商可以选择向诸如CM之类的特定网络设备给予频谱内的专用带宽，以便在任意时间发送分组。在此情况中，CM A被指派为独占地在BW1内发送分组。CM A经由受管理的接入网络和设备420向CMTS 415发送分组。此外，CM B和CM C被指派为分别独占地在BW2和BW3内发送分组。为CM指派独占带宽避免了与其它CM的任何冲突；然而，这需要网络少有的大量带宽，并且在CM不使用带宽时则带宽被浪费。
图5是根据本发明包括了用于发送请求的系统和方法的受管理接入网络的示例。为了解决上述问题，本发明继续使所有CM组125、130、135内的所有网络设备在同一时段期间并且在相同频率带宽中发送请求。然而，网络设备根据分组的优先级在该时段内的指定时间期间发送请求。例如，分组的优先级可以在下面的优先级范围中变化：由连接到计算机的第一CM/MTA 505生成的优先级为3的电子邮件分组、由连接到电视机和相机的机顶盒设备510生成的优先级为5的流传输视频分组、由连接到电话的第二CM/MTA 515生成的优先级为6的语音信号，以及由连接到计算机的第三CM/MTA 520生成的优先级为0的因特网浏览分组。根据本发明，网络设备505、510、515、520将根据所生成的分组的QoS，在请求时段内的特定时间期间向CMTS 525发送请求。
图6是根据本发明由受管理接入网络内的设备采取的、用于请求带宽以发送分组的一连串步骤。最初，在步骤605，CMTS 525向接入网络中的所有网络设备发送用于基于所配置的分组QoS优先级进行请求调度的映射消息(map message)。网络设备将请求调度存储在存储器中以供将来参考。在步骤610，CMTS 525随后分配一时段(例如每5秒分配100微秒(μs))供网络设备请求带宽。在所分配的请求时间期间并且根据所存储的请求调度，在步骤615，想要发送优先级为4-7的分组的网络设备可以在所分配请求时间(即，100μs)内的第一时段期间发送请求分组，并且在步骤620，想要发送优先级为0-3的分组的网络设备可以在请求时间内的第二时段期间发送请求分组。通常，由于所发送的大多数请求分组的优先级较低，因此，可以将第二时段进一步拆分为第三和第四时段。还可以减少第一时段以使得更多时间被分配给任何其它时段从而确保较少的分组冲突。
图7图示出了在网络设备可以根据分组优先级请求带宽的请求时间内的示例时段。根据本发明，CM在指定带宽内(例如10MHz处)发送请求。CM然后经由受管理的接入网络100向CMTS 525发送请求。在所指定的请求时间(例如每5秒的100μs)期间，CM根据优先级和调度图发送请求。例如，对QoS优先级为4-7的分组带宽的请求可以在第一个50μs 730期间发送。此后，对QoS优先级为0-3的分组带宽的请求可以在第二个50μs 735期间发送。如前所述，可以通过下载详细描述了新的调度的另一映射消息，来在任意时刻改变时间段以适应请求分组量的改变。
因此，提供了使得能够基于所生成分组的QoS优先级来发送请求的系统和方法。将会理解，可以预想实现本发明的其它实施例，例如，使用全软件的实施例或者添加了针对另外的特征和服务的实施方式的实施例。
