Definitions
- the present invention relates to a communication technology, and in particular, to a resource management method, system, and network device. Background technique
- IPTV video is a high-bandwidth service and does not allow packet loss.
- the network bandwidth especially the user link bandwidth, is generally very limited.
- resource management must be deployed in the network. , RM) and Connection Admission Control (CAC) functions.
- the IPTV service includes two services: multicast/broadcast video (such as BTV) and unicast video (such as V0D). Since the multicast and unicast service modes are very different, the implementation of the CAC function is different: The multicast CAC is generally completed locally at the access node (Acce ss Node , AN ), and the AN determines whether the user link bandwidth satisfies the request. Add the bandwidth requirement of the channel, or judge whether the number of channels the user joins exceeds the maximum number of restrictions. If the CAC fails (the bandwidth is insufficient or exceeds the maximum number), the user's channel join request is rejected.
- BTV access node
- V0D unicast video
- the unicast CAC function is generally performed by an independent RM server.
- the RM understands the network topology and manages the end-to-end bandwidth from the unicast video server to the user. Therefore, when the user requests the unicast video service, the service server sends the RM server. The resource is requested, and the RM server determines that the end-to-end bandwidth is satisfied, and returns a resource request result, and the service server determines whether to accept the service according to the resource request result.
- resources are reserved for the multicast service and the unicast service on the user link, and are not occupied by each other.
- the local multicast CAC function is completed by the AN, and the RM completes the end-to-end CAC function from the unicast video server to the user.
- the unicast CAC and multicast CAC functions are independent of each other and do not affect each other and remain consistent with the existing network.
- the multicast service and the unicast service cannot share the bandwidth resources, which is a waste of bandwidth resources.
- the application scenario of the solution is limited, and it is only suitable for scenarios where the user link bandwidth is sufficient.
- the AN when a user joins a certain channel, the AN actively sends the channel information that the user joins, directly to the RM or by the BNG (Broadband Ne twork Ga teway, the broadband network gateway sends the RM, judged by the RM Whether the user link bandwidth meets the requirements, and if the demand is not met, notify the AN. Reject user join request.
- This type of multicast user joins the information, and the RM performs CAC processing uniformly, so that the multicast and unicast implementation modes are unified.
- the implementation of the solution is complicated, and the multicast service has a higher switching frequency than the unicast service.
- the frequent switching channels of a large number of TV users may cause a large amount of information interaction, and the performance requirements of the AN are very high; and the multicast service channel switching needs to interact with the RM. , Long switching time, poor user experience.

Description
一种资源管理方法、 系统和网络设备
技术领域
本发明涉及一种通信技术,尤其涉及一种资源管理方法、系统和网络设备。 背景技术
IPTV视频是高带宽消耗的业务, 并且不允许丟包, 而网络带宽尤其是用户 链路带宽一般都非常有限, 为保证视频业务有效开展, 保证业务质量, 必须 在网络中部署资源管理 ( Resource Management , RM ) 和连接接纳控制 ( Connec t ion Admi s s ion Cont ro l , CAC )功能。
在 IPTV业务中, 包括组播 /广播视频 (如 BTV )和单播视频 (如 V0D ) 两种 业务。 由于组播和单播业务模式差别很大, 其 CAC功能的实现也有所不同: 组播 CAC—般在接入节点 (Acce s s Node , AN )本地完成, 由 AN判断用户链 路带宽是否满足请求加入频道的带宽需求, 或判断用户加入的频道数是否超 过了限制的最大数量, 如果 CAC失败(带宽不足或超过了最大数目) , 拒绝用 户的频道加入请求。
单播 CAC功能一般由独立的 RM服务器完成, RM了解网络拓朴, 管理着从单 播视频服务器到用户的端到端的带宽, 因此可以在用户请求单播视频业务时, 由业务服务器向 RM服务器请求资源, RM服务器判断端到端的带宽满足情况, 返回资源请求结果, 业务服务器根据资源请求结果决定是否接纳业务。
在现有的一种方案中, 在用户链路上, 为组播业务和单播业务分别预留资 源, 互不占用。 由 AN完成本地组播 CAC功能, RM完成单播视频服务器到用户的 端到端 CAC功能。 该方案单播 CAC和组播 CAC功能独立, 互不影响, 且保持和现 网一致。 但是, 组播业务和单播业务不能共享带宽资源, 造成带宽资源浪费; 而且, 该方案应用场景受限, 只适合用户链路带宽足够的场景。
在现有的另一种方案中, 用户加入某个频道时, AN主动上 用户加入的频 道信息, 直接发给 RM或由 BNG ( Broadband Ne twork Ga teway , 宽带网络网关 发给 RM, 由 RM判断用户链路带宽是否满足需求, 如果不满足需求, 则通知 AN
拒绝用户加入请求。这种由 ΑίΟ^艮组播用户加入信息,由 RM统一进行 CAC处理, 使组播和单播实现方式统一。 但该方案实现复杂, 而且组播业务比单播业务 切换频率大, 大量电视用户的频繁切换频道会导致大量的信息交互, 对 AN的 性能要求非常高; 而且组播业务频道切换需要和 RM交互, 切换时间长, 用户 体验差。

下面结合具体应用场景进一步描述本发明实施例的实现过程。
参见图 2所示的用户点播单播 V0D业务流程。 用户设备 UE可点播单播 V0D业 务, 也可以收看组播电视业务。
步骤 201-202 : 当 UE点播的单播 V0D业务时, 向 Server (服务器)发送单播 业务请求 (uni ca s t reques t ) , Server接收到 UE发送的单播业务请求, 根据 用户的单播业务请求向 RM发送资源请求以为该 UE请求点播单播 V0D业务的资 源;
步骤 203-204 : RM接收到来自 Server的资源请求, 进行汇聚网的 CAC计算, 完成汇聚网的 CAC计算后, 向接入点 AN发送资源请求, 请求用户链路资源; 步骤 205-206 : 接入点 AN根据接收到的资源请求 (re source reque s t ) , 确定该 UE请求点播单播 V0D业务, 接入点 AN进行本地 CAC计算, 确定本地带宽 足够, 预留出相应带宽, 并向 RM发送申请成功响应消息 (resource rep ly ) ; 步骤 207-208 : RM接收到来自 AN的申请成功响应消息, 向 Server发送申请
成功响应 ( resource reply ) , Server接收到 RM发送的申请成功响应, 向用 户设备返回业务成功响应; Server接纳用户的单播 V0D申请, 开始提供服务。
步骤 209-215: 当用户结束 V0D点播业务时,用户设备 UE通知 Server结束 V0D 业务, Server向 RM发送资源释放请求, RM更新资源数据, 发送资源释放请求 给 AN, AN释放单播资源, 更新资源数据, 返回响应, RM响应 Server资源释放。
参见图 3所示的用户点播单播 V0D业务流程。
步骤 301-302 : 用户通过用户设备 UE点播单播 V0D业务时, 用户设备 UE向 Server发送单播业务请求 ( uni cas t reques t ) , Server接收到 UE发送的单播 业务请求, 根据用户的单播业务请求向 RM发送资源请求以为该 UE请求点播单 播 V0D业务的资源;
步骤 303-304: RM接收到来自 Server的资源请求, 进行汇聚网的 CAC计算, 完成汇聚网的 CAC计算后, 向接入点 AN发送资源请求, 请求用户链路资源; 步骤 305-307 : 接入点 AN根据接收到的资源请求 (resource reques t ) , 确定该 UE请求点播单播 V0D业务, 接入点 AN进行本地 CAC计算, 确定本地带宽 不够;
接入点 AN发现此时有组播业务在线, 于是向连接到该接入点的用户设备 UE 发送组播成员查询消息 ( mul t i cas t membership query ) , 并接收各用户设 备 UE返回的成员响应消息 ( membershi p reply ) ;
其中, 接入点可向用户发送通用组查询或者特定组查询消息, 如果用户没 有响应, 或响应的频道数小于系统记录的频道, 认为某些频道离开报文丟失, 停止转发相应的组播节目, 释放该组播节目占用的资源, 将释放的资源预留 给单播业务;
步骤 308-309 : 接入点 AN根据接收到各成员返回的响应消息确定是否有组 播用户不在线, 如果有则将不在线用户占用的资源释放; 并向资源管理 RM功 能发送申请成功响应 ( resource reply ) 消息;
步骤 310-311 : RM接收到来自接入点 AN的申请成功响应消息, 向 Server发
送申请成功响应 ( re source rep ly ) ; Server收到来自 RM的申请成功响应 ( resource rep ly ) , 向用户设备发送单播业务接纳消息, Server接纳用户 的单播 V0D申请, 开始提供服务。
参见图 4所示的用户设备点播单播 V0D业务流程。
步骤 401-402 : 用户通过用户设备 UE点播单播 V0D业务时, 用户设备 UE向 Server发送单播业务请求 ( uni ca s t reques t ) , Server接收到 UE发送的单播 业务请求, 根据用户的单播业务请求向 RM发送资源请求以为该 UE请求点播单 播 V0D业务的资源; 其中, 资源请求消息中携带了单播视频所需带宽和持续时 间;
步骤 403-404 : RM接收到来自 Server的资源请求, 进行汇聚网的 CAC计算, 完成汇聚网的 CAC计算后, 向接入点 AN发送资源请求, 请求用户链路资源; 其 中资源请求消息中携带了单播视频所需带宽和持续时间;
步骤 405-406 : 接入点 AN根据接收到的资源请求 (re source reque s t ) , 确定该 UE请求点播单播 VOD业务, 接入点 AN进行本地 CAC计算, 确定本地带宽 足够, 预留出相应带宽, 并向 RM发送申请成功响应消息 (resource rep ly ) ; 另外, 接入点还启动保护定时器, 定时器持续时间 (时长)可取单播视频所 需时间, 也可根据一定需要在单播视频所需时间基础上取加权, 如保证用户 视频完整性取时长大于单播视频所需时长, 或者根据用户点播需要取部分时 长;
其中,预留带宽,发送响应消息和启动定时器并没有严格的时间先后顺序。 步骤 407-408 : RM接收到来自 AN的申请成功响应消息, 向 Server发送申请 成功响应 (resource rep ly ) , Server接纳用户的单播 V0D申请, 向用户设备 发送单播业务接纳消息, 开始提供服务。
步骤 409 : 在接入点上, 某些情况下, Server或 RM出现异常, 没有发送资 源释放消息, 当 AN的定时器超时时, AN释放预留给单播的资源。 釆用这种方 式, 既可以防止由于 Sever或 RM异常导致资源无法及时释放导致浪费, 也可便
于运营商对网络业务流量的管理。
参见图 5所示的用户设备加入组播业务流程。
步骤 501-508为用户通过用户设备 UE点播单播 V0D业务过程, 与上述图 2中 步骤 201 - 208过程基本相同;
步骤 509表示在某些情况下, Server或 RM出现异常, 没有发送资源释放消 息。
步骤 51 0: 用户通过用户设备 UE请求加入组播频道;
步骤 51 1-51 3 : 接入点 AN接收到加入组播频道请求, 进行 CAC计算, 发现带 宽不足, 另外接入点发现此时有单播业务在线, 接入点 AN向 RM发送查询消息, 查询单播业务状态; 接入点 AN等待接收 RM返回的响应; 其中, RM可根据本地 信息或者向 Serve r查询该用户单播业务的在线情况返回该单播业务状态; 步骤 514-515 : 接入点 AN根据 RM返回的响应确定单播业务状态, 如果该单 播业务已经不在线, AN释放单播资源, 满足组播业务需求, 并向用户设备 UE 返回组播业务接纳消息。
上述应用场景的网络设备可以是数字用户线接入复用器 DSLAM等宽带接入 设备; 用户设备 UE (或者用户驻地设备 CPE )可为手机、机顶盒( s e t-top-box , STB ) 、 计算机(PC ) 、 家庭网关 (home ga teway , HGW )等, 用户可以通过 上述用户设备 UE可实现多种业务, 如点播单播视频业务(如 V0D ) , 组播视频 业务(如 BTV ) , I P多媒体业务, 视频电话业务等。 网络侧其它存储有该业务 状态的设备可以为独立的资源管理 RM服务器, 也可以为业务服务器等。 上述 方法中的用户设备 UE可以直接连接到宽带接入设备, 也可通过中间网关设备 间接连接到宽带接入设备。
釆用本发明实施例提供的方案, 在宽带接入设备上统一对用户线路资源进 行资源接纳控制, 本发明实施例沿袭现有方案在宽带接入设备实现组播业务 CAC控制, 保证组播业务切换及时满足用户体验, 并在宽带接入设备上实现单 播业务 CAC控制, 使得组播业务和单播业务能够互为感知, 对共享用户链路资
源进行有效管理。 在本发明实施例中, 在用户点播单播 V0D的时候, 由宽带接 入设备实现用户线路的 CAC控制, 还可通过资源管理 RM服务器实现汇聚网的 CAC控制, 只有宽带接入设备和资源管理 RM服务器才有通信, 由于 V0D业务使 用频度低, 不像组播视频业务(如 BTV ) 大量的频道切换, 所以宽带接入设备 和资源管理 RM服务器之间的消息数量少, 而且 V0D业务的响应时间要求比组播 视频业务低, 不需要特别快。 因此, 该方案对宽带接入设备没有过高的性能 要求, 易于实现。
虽然通过实施例描绘了本发明, 但本领域普通技术人员知道, 在不脱离本 发明的精神和实质的情况下, 就可使本发明有许多变形和变化, 本发明的范 围由所附的权利要求来限定。
