一种保护带宽资源的预留方法及系统 Reservation method and system for protection bandwidth resources

技术领域 FIELD

[0001] 本发明涉及包交换网络领域,尤其涉及一种保护带宽资源的预留方法及系统。 [0001] The present invention relates to the field of packet switching networks, and particularly to a protection bandwidth resource reservation method and system. 背景技术 Background technique

[0002] 随着数据业务量的增长和对服务质量(QoS,Quality of Service)要求的提高, 在包交换网络中,目前已采用多协议标签交换(MPLS,Multi-protocol LabelSwitch)、运营商骨干桥接技术(PBB,ftx)vider Backbone Bridge)、基于传送平面的多协议标签交换(MPLS-TP,Transport Profile for MPLS)、虚拟局域网(VLAN,Virtual Local Area Network)交换等技术来实现流量工程(TE,TrafficEngineering)。 [0002] As data traffic growth and improve the quality of service (QoS, Quality of Service) requirements, in packet-switched networks, has been using Multiprotocol Label Switching (MPLS, Multi-protocol LabelSwitch), Provider Backbone bridging (PBB, ftx) vider Backbone bridge), based on the transport plane multiprotocol label switching (MPLS-TP, Transport Profile for MPLS), virtual local area network (VLAN, virtual Local Area Network) exchange technology to achieve traffic engineering (TE , TrafficEngineering). 在传送用户数据之前, 根据用户的要求制定服务水平协定(SLA,Service Level Agreement),通过控制协议预先配置数据的转发路径,分配带宽资源,形成具有带宽等QoS保证的服务流,并且在网络资源状态发生变化时,例如出现链路故障或网络资源使用率发生变化等,进一步调整服务流的转发路径,从而满足用户的QoS要求,所以TE技术目前在运营商网络的应用越来越广泛。 Prior to communicating user data, to develop the user's request service level agreement (SLA, Service Level Agreement), through a control protocol pre-configured forwarding path data, allocate bandwidth, form the service flow has a bandwidth QoS guaranteed and the network resource when the state changes, such as link failure or network resource usage changes, and further adjustment path forwarding service flow to meet the QoS requirements of users, so TE technology is more and more widely in the application of the operator's network. 高带宽、高可用性日益成为包交换网络最重要的特征,链路聚合技术是满足网络高带宽和高可用性的一项重要技术。 High bandwidth, high availability packet-switched network is becoming the most important characteristics, link aggregation technology to meet the high-bandwidth network and an important technique for high availability.

[0003] 链路聚合技术,是指将两台设备间的数条物理链路组合成逻辑上的一条链路,该链路称为一条聚合链路,在逻辑上是一个整体,对于其它设备而言是一条链路,屏蔽了内部的组成和传输数据的细节,具体在IEEE 802. 3ad协议中有规定的描述。 [0003] link aggregation technology, refers to a number of the physical link between the two devices into logical link, the link is referred to an aggregated link is logically a whole, to other devices For a link in the shielding composition and internal details of data transmission, particularly in the IEEE 802. 3ad predetermined protocol is described.

[0004] 显然,链路聚合技术能达到简化网络拓扑的目的;并且,聚合内部的物理链路能共同完成数据收发任务并相互备份,只要还存在能正常工作的成员链路,故障链路上的数据流会切换到其它正常工作的成员链路,整个聚合链路就不会失效,从而在聚合链路内部达到保护业务的目的。 [0004] Obviously, link aggregation technology can achieve a simplified network topology; and, inside of the polymerization can be physical link together to complete tasks and mutual backup data transceiver, as long as there are members of the link, the link failure can work normally on the data stream is switched to the normal operation of the other members of the link, the link will not be the entire polymerization fail to achieve the purpose of service protection within the aggregate link.

[0005] 为了能够有效的根据服务流的不同级别对业务进行保护,专利申请号为EP1921808,发明名禾尔为Preemptive transmis sion protection scheme for dataservices公开了一种方法:在由多个成员链路构成的聚合链路上,根据业务类型,将不同的业务映射到不同的成员链路上,并根据业务类型为业务分配工作带宽资源和保护带宽资源;聚合链路中包括至少一个工作链路和至少一个备份链路,工作链路承载高优先级的业务,备份链路承载低优先级的业务;当工作链路故障时,能够将高优先级的业务从故障链路上切换到备份链路上传送。 [0005] In order to effectively protect the business flows according to different levels of service, Patent Application No. EP1921808, Seoul to names Wo invention Preemptive transmis sion protection scheme for dataservices discloses a method: constituted by a plurality of link members the aggregated link, according to service type, different services mapped to different members of the link, and traffic distribution according to the service type of the operating bandwidth and the protection bandwidth resource; polymeric link comprising at least one working link and at least a backup link, working link carry high priority traffic, low-priority backup link bearer traffic; when the working link failure, high priority traffic can be switched from the failed link to the standby link upload give away. 该专利申请的技术方案能通过服务流的优先级高低和预先预留资源对服务流实现有效的保护,但缺点是该方案没有对聚合链路的保护带宽资源的预置方式进行说明,也没有提供如何泛洪聚合链路的带宽资源信息、采用何种策略来预留保护带宽资源的相关实现方案。 Aspect of this patent application by the priority level of the service flow and the previously reserved resources to achieve effective protection of the service flow, but the drawback is that the program preset mode polymerizable no protection bandwidth link will be described, there is no how to provide flood information link aggregation bandwidth resources, what strategies employed to protect the reserve related to implementation of bandwidth resources.

具体实施方式 detailed description

[0040] 本发明的基本思想是:根据聚合链路的成员链路的带宽使用信息和所述聚合链路上承载的待建服务流的带宽信息,选择承载待建服务流的成员链路,并为待建服务流预留保护带宽资源。 [0040] The basic idea of ​​the present invention are: the use of information according to the bandwidth of the link members of the aggregated link bandwidth information and services to be built flow carried on the polymeric link, the link member selected bearer service flow to be built, and to reserve bandwidth resources to be built to protect the service flow.

[0041] 下面通过附图及具体实施例对本发明再做进一步的详细说明。 [0041] By following drawings and specific embodiments of the present invention do further described in detail.

[0042] 本发明是对聚合链路的保护带宽资源进行预留的方法,使用该方法的触发条件可以是信令请求、网管配置请求等。 [0042] The present invention is a polymeric protection bandwidth reserved link method, the method using the trigger condition may be a signaling request, and other network configuration request. 本发明中的服务流的标识可以是标签交换路径(LSP, Label Switch Path)、VLAN、介质访问控制(MAC,MediaAccessControl)、VLAN+MAC 等标识对应的各种服务流。 Identifying service flow in the present invention may be a label switched path (LSP, Label Switch Path), VLAN, medium access control (MAC, MediaAccessControl), VLAN + MAC and other service flow corresponding to the identifier.

[0043] 在本发明中的服务流用“SFlow”表示,当服务流个数不止一个时,用“Sf lows”表示。 [0043] In the present invention, the service flow with "SFlow" means that when more than one service flow number, by "Sf lows" FIG. 此外,为避免用户数据包传递中发生错序,本发明中的每个LSP不能同时跨多个成员链路传送,这样,未预留最大LSP带宽应是所有成员链路未预留带宽中的最大值。 Further, in order to avoid sequence errors occurred in the user data packet transfer, in the present invention across each LSP can transmit a plurality of link members such that the maximum LSP bandwidth should not be reserved for all the members of the link bandwidth unreserved maximum.

[0044] 图1是本发明保护带宽资源的预留方法的实现流程示意图,如图1所示,该方法包括以下步骤: [0044] FIG. 1 is a process implemented method for protection bandwidth reserved resources according to the present invention, a schematic diagram, shown in Figure 1, the method comprising the steps of:

[0045] 步骤101,根据聚合链路的成员链路的带宽使用信息和该聚合链路上承载的待建服务流的带宽信息,选择承载待建服务流的成员链路; [0045] Step 101, using the bandwidth of the link members of the link aggregation information and the information to be built aggregate bandwidth bearer service flows on a link, selecting a bearer service flow to be built in the link member;

[0046] 具体的,聚合链路的端点收到网管的建立信令后,根据信令携带的路由信息,确定待建SFlow经过的自身所在的聚合链路;当待建SFlow通过该聚合链路时,聚合链路的端点计算该聚合链路的每条成员链路的带宽使用信息,该带宽使用信息指的是成员链路的可用带宽的大小;计算完成后,聚合链路的端点的链路管理模块根据其上承载的待建SFlow的带宽信息和聚合链路的成员链路的带宽使用信息,在聚合链路的多条成员链路中选出一条成员链路作为该待建SFlow的承载链路。 [0046] Specifically, after the endpoint receives aggregated link establishment signaling network, according to the routing information carried in signaling, determining the link itself to be built where the polymerization SFlow elapsed; when SFlow be built by this polymerization link endpoint, calculating aggregation link bandwidth utilization information for each of the link members of the aggregated link, the bandwidth available bandwidth information refers to the size of the link member; completion of the calculation, the polymeric chain end of a link road information according to the bandwidth management module member link to be built SFlow bandwidth information and links the polymerization carried thereon, as the link is selected to be a member of the plurality of members built SFlow aggregated link in bearer link.

[0047] 步骤102,为待建服务流预留保护带宽资源; [0047] Step 102, the bandwidth of the reserved resources for the protected service flow to be built;

[0048] 具体的,在为待建SFlow选出承载链路后,为先选择聚合链路中的另一条成员链路作为待建SFlow的保护链路,并在该保护链路上为待建SFlow预留保护带宽资源;如果预留保护带宽资源失败,执行步骤103,如果预留保护带宽资源成功,执行步骤104。 [0048] Specifically, after the bearer links is selected SFlow be built, as the first link member selected polymeric another link to be built as a protection link SFlow and on the protection link is to be built SFlow reserved protection bandwidth resources; if protection bandwidth reserved resource fails, step 103, if the reserved protection bandwidth resources successfully, step 104 is performed.

[0049] 步骤103,为已经存在的服务流重新选择承载链路,并重新为待建服务流预留保护带宽资源,结束当前处理流程; [0049] Step 103, to re-select a bearer link existing service flow, and re-protection bandwidth to reserve resources for the service flow to be built, ending the current process;

[0050] 具体的,当为待建SFlow预留保护带宽资源失败时,聚合链路的端点的链路管理模块会发起一次负载均衡调整,将已经存在的SFlow在聚合链路的成员链路内进行调整, 重新为已经存在的SFlow选择承载链路,选择完毕后重新为待建SFlow预留保护带宽资源, 如果本次预留保护带宽资源成功,则结束流程;如果本次预留保护带宽资源仍然不成功,则停止为待建SFlow预留保护带宽资源,继续待建SFlow的配置; [0050] Specifically, when the failure to protect the reserved bandwidth resources to be built SFlow, aggregated link endpoint management module will initiate a link load balancing adjustment, within existing SFlow member of an aggregated link adjust, re-select the bearer link to existing SFlow, selected after completion of re-reserved protection bandwidth resources for SFlow to be built, if this protection bandwidth resources reserved successful, the process ends; if this protection bandwidth resources reserved still unsuccessful, then stop to be built SFlow reserved protection bandwidth resources, continue to be built SFlow configuration;

[0051] 这里,继续待建SFlow的配置属于现有技术,此处不再赘述;对于预留保护带宽资源失败的待建SFlow,表明聚合链路无法为其提供保护带宽资源,如果此后承载该待建SFlow的成员链路发生故障,可以通过重路由等方式进行解决,关于解决方案属于现有技术,此处不再赘述。 [0051] Here, to continue to be built belongs to the prior art configuration SFlow, is not repeated here; for protection bandwidth reserved resources fail to be built SFlow, indicated that the polymerization can not provide protection link bandwidth, if the carrier thereafter to be built SFlow member link fails, it can be resolved by re-routing, etc., on solutions to existing techniques is not repeated here.

[0052] 步骤104,重新计算聚合链路的带宽; [0052] Step 104 recalculates the bandwidth aggregation link;

[0053] 具体的,当为待建SFlow预留保护带宽资源成功时,聚合链路的端点的链路管理模块根据聚合链路的成员链路的带宽使用信息,重新计算聚合链路的最大可预留LSP带宽,并泛洪计算出来的最大可预留LSP带宽。 [0053] Specifically, when the reserved protection bandwidth resources successfully SFlow to be built, the aggregated link end of a link management module member link information based on the bandwidth of the aggregated link, the link is re-calculated maximum polymerized LSP reserved bandwidth and flooding calculated maximum reservable LSP bandwidth.

[0054] 上述方法是针对的情景是:不需要在网络中泛洪聚合链路的保护类型,直接由聚合链路的端点为待建SFlow选择成员链路和预留保护带宽资源;因此该方法中无论聚合链路是无保护还是共享保护的保护类型,都能够为待建SFlow预留保护带宽资源。 [0054] The method for the scenario are: no need to flood the network link protection type of the polymerization, it is built SFlow select members and link resources reserved protection bandwidth directly from the endpoint of the aggregated links; thus this method whether in the aggregated link is unprotected or protected by a shared type of protection, we are able to reserve bandwidth resources for the protection SFlow to be built. 同时,本发明还提供一种针对保护类型是共享保护的聚合链路的保护带宽资源的预留方法,该方法只需要在步骤101之前增加下述内容,其他步骤同步骤101至步骤104 ; Meanwhile, the present invention also provides a method for protecting the reserved bandwidth resource is a shared protection type of protection against aggregation links, which only need to add the following content before step 101, step 101 with the other steps to step 104;

[0055] 在步骤101之前增加步骤:配置聚合链路的保护类型为共享保护,并在网络中泛洪聚合链路的保护类型; [0055] increase before step 101: the configuration of the link protection type polymerization shared protection, and flooding the network link protection type of the polymerization;

[0056] 具体的,在网管上可以配置聚合链路的保护类型,保护类型包括共享保护和无保护;聚合链路的保护类型配置完毕后,控制平面在网络内部对该聚合链路的保护类型进行泛洪; [0056] Specifically, the polymerization can be configured in the network link protection type, protection types include shared protection and unprotected; Once configured, the link protection type of polymerization, the internal network control plane link protection type of the polymerization flooding;

[0057] 如果聚合链路的保护类型是共享保护,则还需要在网管上设置该聚合链路的成员链路的固定预留作为保护带宽资源的带宽的百分比,该百分比大于O且小于100%,同时在对该聚合链路的保护类型进行泛洪时,泛洪带宽还需要减去上述预留的带宽的百分比;如果聚合链路的保护类型是无保护,这里不需要为待建SFlow预留带宽,泛洪带宽为未预留最大LSP带宽。 [0057] If the polymerization of the link protection type is a shared protection is required to reserve a fixed member disposed links of the polymeric network in the guard bandwidth as a percentage of bandwidth resources, the percentage is greater than O and less than 100% while when the link protection type of polymerization flooding, flooding the bandwidth required by subtracting the percentage of the bandwidth reservation; If the polymerization of the link protection type is unprotected, there is no need to be pre-built SFlow stay bandwidth flooding unreserved bandwidth is the maximum LSP bandwidth.
