Description

一种聚合链路切换时的报文控制方法、系统和节点 A polymeric packet control method, and a system of link switching node

技术领域 FIELD

[0001] 本发明涉及分布式链路聚合组的聚合链路切换技术,尤其涉及一种聚合链路切换时的报文控制方法、系统和节点。 [0001] The present invention relates to a distributed switching LAG link aggregation technology, and particularly relates to message control method, system and a link switching node polymerization.

背景技术 Background technique

[0002] 随着宽带业务的飞速发展,网络与网络之间的互连使用得越来越多,承载了更多的业务。 [0002] With the rapid development of the interconnections between the broadband network and the network increasingly used, carrying more traffic. 网络内部根据采用的技术,均可有多种方法对链路及链路上的节点实现保护。 The internal network technology used, there may be various methods to achieve the protection of the nodes on the link and the link. 随着对流量的保护需求越来越强烈,要求越来越高,有运营商也提出了需要在网络互连区域做保护的需求。 With the protection needs of increasingly strong flow, the increasingly high demand, operators have also raised needs to be done to protect the network interconnect regional needs. 这里的保护可以通过采用端口聚合的方式来实现,常用的方式可以是端口聚合,也可以是环路保护。 Protection can be achieved here by way of polymerization and a port, the port may be a common way of polymerization, the loop may be protected. 环路保护技术受到网络拓扑的限制,对于网络互连部分采用全网连接的方式不适用。 Loop protection technology is limited by the network topology, the network interconnection part is connected by way of the whole network is not applicable. 因此,为了适用于网络与网络互连区域组网方式更加多样化,并能实现不仅对链路的保护,而且实现对边缘节点的保护,IEEE标准组织提出了扩展链路聚合,通过一种分布式的链路聚合组DRNI来实现链路和节点双冗余的网络互连保护需求,即聚合组的端点处由多个节点组成,这些节点的聚合链路组成一个聚合链路组。 Therefore, in order for network interconnection with a network area networking more diverse, and can be realized not only protects the link, but also achieve the protection of the edge node, IEEE Standards Organization extended link aggregation, by means of a distribution LAG DRNI formula to achieve dual redundant links and nodes of the network interconnection protection requirements, i.e., polymerizable by a plurality of endpoint nodes, the nodes of the aggregated links constitute a link polymerizable group. 如图1所示,链路聚合组(LAG)的两个端点A、B都有2个节点:系统1、系统2和系统3、系统4,这4个系统的多条链路聚合在一起,形成了一个聚合组LAG,通过这个LAG,能够实现链路和节点的双重保护,这里,端点A中的系统1、系统2之间通过内链链路连接,端点B的系统3、系统4之间也通过内链链路连接。 As shown, the link aggregation group (the LAG) is a two endpoints A, B has two nodes: System 1, System 2, and System 3, 4 system, a plurality of links four systems together of forming a polymerizable the LAG, the LAG through this, double protection can be achieved links and nodes, where the endpoint system a is 1, the system is connected through a chain link between the two, the terminal B 3 system, the system 4 between the inner chain link is also connected through.

[0003] 在现有标准802.1AX中,链路聚合组的每个端点仅支持单节点的情况,即只能实现单个节点上的链路聚合,形成链路聚合组LAG。 Where [0003] In the prior standard 802.1AX each endpoint supports only single link aggregation node, i.e. the link aggregation can only be achieved on a single node, forming a link aggregation group LAG. 所述802.1AX中包括一个标记(Marker)协议, 用于对聚合链路进行切换时,保证报文的有序传输,具体过程如下: The 802.1AX includes a marker (Marker) protocol is used for the polymerization of the link switching, to ensure orderly transmission of packets, the specific process is as follows:

[0004] a •对聚合链路进行切换的设备停止在所述聚合链路上发送业务报文; [0004] a • links to the polymerization apparatus for switching stop sending traffic packets over the aggregated links;

[0005] b.所述设备利用Marker协议,向所述聚合链路的对端设备发送Marker PDU,并启动定时器; . [0005] b Marker protocol using the device transmits Marker PDUs to the peer link polymerization apparatus, and starting a timer;

[0006] C.所述设备判断在定时器超时前是否收到所述对端设备的Marker Response PDU,如果收到,立即执行步骤d;如果没有收到,则默认所述对端设备已经接收到所述Marker PDU或已经丢弃所有在启动定时器之前发送的业务报文,在定时器超时时执行步骤d; [0006] C. The device determines whether it has received before the timer expires the Marker Response PDU to the remote device, if received, immediately step D; if not received, the default device has received the peer Marker PDU to the service or discard all packets have been transmitted before the timer is started, the timer times out when performing step D;

[0007] 所述定时器的定时时间尽量选择大些,保证在定时时间内,所述聚合链路上己经没有业务报文在传送。 The timing of time [0007] to select a bigger timer to ensure that within the timing of the polymeric link has no traffic in packet transmission.

[0008] d •对聚合链路进行切换的设备将所述聚合链路上的业务报文分发到新的选中(selected)状态的聚合组成员端口上。 Equipment [0008] d • links to the polymerization of the polymeric switching traffic on link packets distributed to the new selected (selected) port member state of aggregation.

[0009] 上述过程对于端点包括多个节点的情况不适用,因为这时的聚合链路切换可能是跨节点的,如果一个节点收到了Marker协议报文,例如上述过程中的Marker PDU,所述节点无法保证自身所在的端点内其他节点已经完成了对所述Marker协议报文的转发,因此也无法对对端做出Marker协议回复。 [0009] In the case of the above-described process comprises a plurality of end nodes does not apply, because the polymerization time may be cross-link switching node, if a node receives a Marker protocol packets, e.g. Marker PDUs in the above process, the node within the endpoint itself can not guarantee where the other node has completed forwarding to the Marker protocol packets, and therefore can not make a Marker agreement to end reply.
