具体实施方式 Detailed ways

[0030] 为了使本发明的技术方案更加清楚明白,下面结合附图和具体实施例对本发明做进一步详细阐述。 [0030] In order to make the technical solutions of the present invention will become apparent from, the accompanying drawings and the following specific embodiments of the present invention will be further elaborated. 需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的各种方式可以相互组合。 Incidentally, in the case of no conflict, the present application examples and embodiments can be combined in various ways.

[0031] 本发明提供一种基于以太网链路级OAM优化LACP协议链路聚合的方法,包括: [0031] The present invention provides a method for link-level Ethernet OAM protocol LACP optimization based on link aggregation, comprising:

[0032] 步骤S1:处于聚合组中的端口使用LACP协议,建立聚合链路。 [0032] Step S1: The port is in use in the LACP aggregation, aggregated link establishment.

[0033] 在具体实施时,处于聚合组中的物理端口自动运行LACP协议,通过发送LACP报文在本端端口和对端端口之间进行协商:设备ID (系统优先级+系统MAC地址)小的一端被认为优,在优的一端选择端口ID(端口优先级+端口号)小的端口作为参考端口,与参考端口的key相同,且该端口的对端端口与参考端口的对端端口key值也相同的端口,选为selected端口,根据设备的聚合能力,把两端口协商一致且处于selected的端口聚合在一起,形成聚合链路。 [0033] In a specific embodiment, the physical port in the aggregation of the LACP automatic operation, by sending LACP packets negotiation between the local port and the end port: Device ID (system priority system MAC address) small end is considered excellent, select the port ID in the superior end (port priority + port number) small port as a reference port, and the reference key port of the same, and the peer port in reference peer port key port of the port values ​​are also the same port, preferably a port selected according to the aggregation capability of the device, the two-port consensus and in selected ports aggregated together to form an aggregated link.

[0034] 步骤S2 :创建业务之后,在聚合链路中的某一工作链路的两个端口上自动运行OAM协议,监测该工作链路的性能。 [0034] Step S2: After creating the service, automatically run the OAM protocol on both ports of a polymeric links working link, monitoring the performance of the working link.

[0035] 在具体实施时,链路事件包括错误符号周期事件、错误帧事件、错误帧周期事件和错误帧秒累积事件,能够达到实时监测链路性能的目的。 [0035] In a specific embodiment, link events include error events symbol period, a frame error event, the errored frame period and the second frame error accumulation event, to achieve the purpose of real-time monitoring link performance. 客户可以选择其中之一或根据实际情况利用多种事件组合来反应链路的性能参数指标。 The customer can select one or more events using a combination of performance parameters to reflect the actual situation in the link metrics.

[0036] 以错误帧事件为例: [0036] in the wrong frame event as an example:

[0037] 当N*Window监测周期内,Event次数超过规定的性能阈值PefThreshold,则链路 [0037] When the monitoring period N * Window, Event performance times exceeds a predetermined threshold value PefThreshold, the link

需要重新聚合。 We need to re-polymerization.

[0038]在一个 Window 监测时间内,RxErroredSymbol ^ Threshold, [0038] Window in a monitoring period, RxErroredSymbol ^ Threshold,

[0039]则 ErrFrameEvent = RxErroredSymbo1/ThreshoId ; [0039] the ErrFrameEvent = RxErroredSymbo1 / ThreshoId;

[0041] ErrPef+ = ErrFrameEvent ; [0041] ErrPef + = ErrFrameEvent;

[0042] 若ErrPef彡PefThreshold,则链路需要重新聚合。 [0042] When ErrPef San PefThreshold, the need to re-link polymerization.

[0043] 步骤S3 :如果监测到该工作链路的性能低于设定的性能标准,则停止该工作链路的聚合。 [0043] Step S3: If the performance monitoring of the working link is below the set of performance criteria, the polymerization is stopped the working link.

[0044] 如果工作链路的性能低于设定的性能标准,则设置该工作链路的两端端口的LACP_Enabled = FALSE,即关闭端口的LACP协议,重新建立聚合链路。 [0044] If the performance of the work link is below performance standards set, both ends of the working link is set port LACP_Enabled = FALSE, i.e. closing port LACP, to re-establish the link polymerization.

[0045] 而且,当一条链路聚合后劣化退出聚合组,如果之后确定这条链路已经恢复,则需要手动使能端口的LACP_Enabled = TRUE,使其参与链路聚合。 [0045] Further, when a deterioration of the link aggregation removed from the group, if it is determined after the link has been restored, it is necessary to manually make LACP_Enabled = TRUE on a port, so that participation in link aggregation.

[0046] 如果处于聚合链路中的所有的工作链路的性能都低于设定的性能标准,则选择性能指标衡量值错误性能(ErrPef)最小的链路作为工作链路,使能LACP_Enabled = TRUE。 [0046] If all of the properties in the polymerization of working links in the chain are below the performance standards set value is selected performance measure error performance (ErrPef) link as a minimum working link, enabling LACP_Enabled = TRUE.

[0053] 以下示例性地说明利用帧错误事件衡量聚合链路的性能: [0053] The following example illustrates the polymerization using a frame error event link performance measure:

[0054]设定 ErrFrameWindow = 60 (s), ErrFrameThreshold = 1000, PefThreshold = 8,N = 10 : [0054] setting ErrFrameWindow = 60 (s), ErrFrameThreshold = 1000, PefThreshold = 8, N = 10:
