Description

_种业务流量的泛洪方法和设备 _ Kinds of traffic flooding method and apparatus

技术领域 FIELD

[0001] 本发明涉及通信技术领域,特别涉及一种业务流量的泛洪方法和设备。 [0001] The present invention relates to communication technologies, particularly to a traffic flooding method and apparatus.

背景技术 Background technique

[0002] 当今大多数企业网络及其数据中心跨越了多个位于不同地理位置的物理站点,并在这些站点部署类似的业务。 [0002] Most of today's enterprise networks and data centers across multiple physical sites located in different geographical locations, and deploy a similar business in these sites. 为了对数据中心资源进行整合、降低管理成本,通常会对数据中心的资源进行虚拟化。 In order to consolidate data center resources, reduce management costs and resources typically have data centers to be virtualized. 数据中心的虚拟化技术主要包括网络虚拟化、存储虚拟化和服务器虚拟化这三方面内容。 Data center virtualization technology including network virtualization, storage virtualization and server virtualization these three aspects. 其中,服务器虚拟化是通过专用的虚拟化软件(如VMware)在一台物理服务器上虚拟出多台虚拟机,每台虚拟机都独立运行,拥有自己的操作系统、应用程序和虚拟硬件环境(包括虚拟的CPU、内存、网卡等)。 Among them, through a dedicated server virtualization is virtualization software (such as VMware) virtualizes multiple virtual machines on a single physical server, each virtual machine can run independently, with its own operating system, applications, and virtual hardware environment ( including virtual CPU, memory, network card, etc.). 为了实现站点间的资源动态调配和管理, 虚拟机在数据中心的不同站点之间要能够自由迀移。 In order to achieve dynamic allocation and management of resources between sites, between different virtual machines in the data center site to be able to move freely Gan. 如图1所示,为现有技术中的一种虚拟机迀移场景的示意图。 As shown in FIG. 1, a schematic view of the prior art to shift the scene of one virtual machine Gan. 虚拟机可以在Site(站点)1的服务器ServeK服务器)1和Site2的服务器Serverf之间进行迀移。 Virtual machines can) be Gan shift between 1 and Site2 server Serverf in Site (Site) server ServeK server 1. 由于虚拟机迀移过程对用户透明,不能改变IP地址,否则用户的访问流量会中断,所以必须在分布于异地的站点之间实现二层网络互联。 Because virtual machines Gan shift process transparent to the user, can not change the IP address, otherwise the user traffic will be interrupted, it is necessary to implement Layer 2 network interconnection between sites located in different places.

[0003] EVKEthernet Virtualization Interconnect,以太网虚拟化互联)是一种先进的"MAC in IP"技术,是一种基于IP核心网的二层VPN(Virtual Private Network,虚拟专用网络)技术。 [0003] EVKEthernet Virtualization Interconnect, Ethernet Virtualization Interconnection) is an advanced "MAC in IP" technology, is an IP-based core network Layer VPN (Virtual Private Network, virtual private network) technology. 它可以基于现有的服务提供商网络和企业网络,为分散的物理站点提供二层互联功能。 It can be based on existing service provider and enterprise networks, providing Layer 2 communication capabilities for distributed physical site. EVI只是在站点的边缘设备上维护路由和转发信息,无需改变站点内部和IP核心网络的路由和转发信息。 EVI just maintain the site on the edge of the device routing and forwarding information, without changing the internal routing and IP core network sites and forwarding information.

[0004] 如图2所示,为现有技术中的一种EVI组网结构的示意图。 [0004] As shown in FIG 2, EVI networking structure diagram of a prior art is. 部署EVI后的网络由以下三部分组成: EVI network after deployment consists of the following three parts:

[0005] 站点网络:通过一台或者多台边缘设备连接到核心网络的具有独立业务功能的二层网络,通常由单个企业管理控制,主要由主机和交换设备组成。 [0005] Internet site: to the core network through an edge device or a plurality of layer 2 network having a separate business function, usually controlled by a single enterprise management, mainly by the host and switching devices.

[0006] EVI网络:站点边缘设备之间建立的虚拟网络,提供站点网络之间的二层互联。 [0006] EVI network: the site is established between the virtual network edge devices, providing Layer 2 communication between the network of sites. 通过EVI网络在站点之间相互通告连接到边缘设备的所有主机和设备的MAC地址,将多个站点互联形成更大的二层转发域。 Notice each edge device is connected to the network via EVI sites between the MAC addresses of all hosts and devices, the plurality of sites interconnected to form larger Layer 2 forwarding domain.

[0007] IP核心网络:主要由IP路由设备组成、提供站点网络之间三层互联的网络。 [0007] IP core network: mainly composed of IP routing equipment, to provide three-site network interconnection between networks.

[0008] 通过EVI网络可以实现VLAN(Virtual Local Area Network,虚拟局域网)流量在不同站点之间的扩展(例如:将站点Sitel中VLAN10的流量扩展到站点Site2和Site3),EVI 网络承载了站点间扩展VLAN的二层流量。 [0008] may be implemented VLAN (Virtual Local Area Network, VLAN) traffic between different sites extended EVI through a network (e.g.: Sitel in the extended site-to-site traffic VLAN10 Site2 and Site3), EVI network carrying the inter-site extended Layer 2 traffic VLAN.

[0009] EVI技术具有如下优点: [0009] EVI technology has the following advantages:

[0010] 站点间相互独立:站点间二层互联后,某个站点的故障(如广播风暴)不会传递到其它站点,不同站点的拓扑互不影响和依赖。 Between [0010] independently of one another site: Layer 2 communication between the sites, a site failure (broadcast storm) is not transmitted to the topology of the site do not affect each other, and dependent on different sites.

[0011] 技术要求低:只要求服务提供商网络支持IP即可,无其它特殊技术要求。 [0011] the technical requirements of the low: only require Internet service providers to support IP, no other special technical requirements.

[0012] 高可靠性:使用多归属来提供站点的冗余接入,并具有在站点间避免流量环路的机制。 [0012] High Reliability: the use of multiple home access sites to provide redundancy and to have a mechanism to avoid the flow loop between sites.

[0013] 高链路使用效率:站点之间的组播和广播流量得到充分的优化从而节省带宽,在有冗余链路时可以实现负载分担。 [0013] high link efficiency: multicast and broadcast traffic between the sites to be fully optimized to conserve bandwidth, when the redundant links to implement load balancing.

[0014] 灵活性:站点间二层互联不依赖于站点的拓扑结构,对站点拓扑结构没有特殊要求。 [0014] Flexibility: Layer 2 communication between sites is not dependent on the topology of the site, no special requirements for the site topology.

[0015] 运营维护简单、成本低廉:只需要在站点边缘部署一个或多个支持EVI功能的设备,企业网络和服务提供商网络无需做任何变动。 [0015] operation and maintenance simple, low cost: only need to deploy one or more devices support EVI functions in edge sites, corporate networks and Internet service providers do not need to make any changes. 并且站点边缘设备上的配置简单,部署过程对流量转发不产生影响。 And configure the device on the edge of the site is simple, deployment of traffic forwarding no effect.

[0016] 缺省情况下,边缘设备对于未知地址的帧(包括未知单播帧和未知组播帧)只在VLAN内的站点内部接口上进行泛洪,不会泛洪到其它站点。 [0016] By default, the edge device for the unknown frame address (including an unknown unicast frames and multicast frames) only in the VLAN flooding the internal interface on the site, is not flooded to other sites.

[0017] 对于某些特定的数据中心业务,以特定的目的MAC地址来标识其业务流量,该MAC 地址永远不会作为数据帧的源MAC地址,不能通过EVI IS-IS协议在边缘设备之间进行通告。 [0017] For certain data center business, a particular destination MAC address to identify its traffic, the MAC address as the source MAC address will never be data frames, can not be between EVI IS-IS protocol edge device advertise. 为了保证这类业务的流量在站点间的互通,可以配置选择性泛洪的MAC地址,当报文的目的MAC地址匹配该MAC地址时,报文可以通过EVI隧道泛洪转发到其它站点。 In order to guarantee traffic service interworking between such sites may be selectively flooding MAC address of the packet when the destination MAC address matches the MAC address, the packet can be forwarded to other sites through the tunnel EVI flooding. 这种MAC被称为选择性泛洪的MAC地址。 This is called MAC address MAC selective flooding.

[0018] 在实现本发明实施例所提出的技术方案的过程中,发明人发现现有技术存在以下不足: [0018] In the implementation of the technical solutions proposed in the embodiment of the present invention, the inventors have found that the prior art has the following disadvantages:

[0019] 当本端站点边缘设备配置泛洪MAC后,业务流量的目的MAC地址匹配该MAC地址时, 会被泛洪到其他所有具有相同激活VLAN的远端站点边缘设备。 When [0019] When the local station MAC flooding edge device configuration, traffic destination MAC address matches the MAC address will be flooded to all other sites distal edge devices having the same activation VLAN. 即使远端站点边缘设备并没有提供这个服务的能力,也会接收到此业务流量,占据了不必要的带宽,影响远端站点边缘设备正常的业务通信。 Even if the remote site capability edge equipment does not provide this service, you will receive this traffic, accounting for unnecessary bandwidth, affecting the normal edge of the remote site equipment business communications.

具体实施方式 detailed description

[0036] 如背景技术所述,在现有技术方案中,业务流量会被泛洪到其他所有具有相同激活VLAN的远端站点边缘设备,在该远端站点边缘设备并没有提供这个服务的能力的情况下,这样的转发显然是没有必要的,因此,这样的转发占据了不必要的带宽,影响远端站点边缘设备正常的业务通信。 [0036] As described in the background, in the prior art embodiment, the traffic will be flooded to all other remote sites to activate with the same VLAN edge devices and the remote site edge device does not provide the ability to service under the circumstances, this is obviously not necessary to forward, therefore, such a forwarding occupy unnecessary bandwidth, affecting normal business communication with a remote site edge devices.

[0037] 为了解决这样的问题,本发明实施例提出了一种业务流量的泛洪方法,主要解决实现EVI网络中业务流量按需向特定站点(或特定站点的某个接口)进行泛洪,也就是说只向能提供业务服务的站点泛洪,不向其他站点泛洪,保证了站点中流量的有效性,有效防止流量在站点内以及站点间的泛洪。 [0037] In order to solve such a problem, embodiments of the invention proposes a method for traffic flooding, addressing achieve EVI network is flooded traffic demand to a specific site (site-specific or an interface), That is only to be able to provide business services site flooding, not to other sites flooding, to ensure the effectiveness of site traffic, effectively preventing the flow within the site and inter-site flooding.

[0038] 如图3所示,为本发明所提出的一种业务流量的泛洪方法的流程示意图,该方法应用于EVI网络系统中,具体包括以下步骤: [0038] The flow diagram of a method of traffic flooding shown in Figure 3, the present proposed invention, the method is applied EVI network system, comprises the steps of:

[0039]步骤S301、本端站点边缘设备在自身的EVI隧道下配置各种业务类型的业务流量转发到远端设备所需的各泛洪MAC地址,并建立与所述各泛洪MAC地址相对应的泛洪MAC表项。 [0039] In step S301, the local station at the edge device itself EVI tunnel configuration of various types of service traffic forwarded to the respective flood desired remote device MAC address, and establishing the MAC address with each flooding flooding the corresponding MAC entries.

[0040] 其中,所述泛洪MAC表项中记录各所述泛洪MAC地址所对应的有效泛洪站点的信息。 [0040] wherein the recording information is valid MAC flooding flooding flooding each of the sites corresponding to the MAC address entry.

[0041] 需要指出的是,对于本端站点边缘设备来讲,每一个泛洪MAC表项的建立过程都是一次新的表项建立过程,而对于该泛洪MAC表项的内容的更新则根据具体更新时间和规则的差异分为以下两种情况: [0041] It should be noted that, for the local site edge equipment is concerned, the process of establishing a flood each MAC entry is a new entry building process, and update the content of the flooding of the MAC entry There are two cases according to differences in the specific time and update rules:

[0042]情况一、首次建立泛洪MAC表项的过程。 [0042] a situation, for the first time establish a flooding process MAC entries.

[0043] (1)当所述本端站点边缘设备在自身的EVI隧道下配置一种新的业务类型的业务流量转发到远端设备所需的泛洪MAC地址时,所述本端设备建立与该泛洪MAC地址相对应的泛洪MAC表项,其中,所建立的泛洪MAC表项中所记录的该泛洪MAC地址相对应的有效泛洪站点的信息的初始值为缺省值。 When [0043] (1) when the local site edge device configuration of a new type of service traffic in the tunnel itself EVI flooding forwarding MAC address to the desired remote device, the local device establishing the flooding and MAC address corresponding to the MAC flooding entries, wherein the initial information is the default value of the MAC address flooding flood MAC entry created recorded corresponding to the active site flooding .

[0044] 通过本过程的处理,本端站点边缘设备完成了泛洪MAC表项的初始建立过程,所建立的泛洪MAC表项中,存储了业务类型和泛洪MAC地址之间的对应关系,需要指出的是,这里的业务类型和泛洪MC地址之间是一一对应的关系。 [0044] By the process according to the present process, the end edge device of site completed the initial setup process flooding MAC entries, flood the MAC entry created in the stored correspondence relationship between the service type and MAC address flooding , it should be noted that, here is one to one relationship between the business and the type of flooding MC address.

[0045] 进一步的,由于是初始建立过程,其所对应的有效泛洪站点的信息是空缺的,所以,本发明实施例中以缺省值进行暂时的填充。 [0045] Further, since the initial establishment procedure, information is valid flooding its corresponding site is vacant, so that, for example, the default values ​​to fill temporarily embodiment of the present invention. 而具体的有效泛洪站点的信息则是通过后续的步骤进行获取和更新。 Specific information and flooding the site is valid is acquired and updated by the subsequent steps.

[0046] (2)所述本端站点边缘设备在向远端站点边缘设备发送的一个或多个消息中携带请求状态的所述新的业务类型的泛洪MAC信息,请求与该泛洪MAC地址相对应的有效泛洪站点的ig息。 [0046] (2) the local station of the new service type of MAC flooding request status information carrying edge device in a transmitting station to a remote device or a plurality of edge messages, requesting the MAC flooding ig address information should be relatively effective flood site.

[0047] 在本实施例所提出的技术方案中,泛洪MAC信息实际上就是本端站点边缘设备和远端站点边缘设备之间进行有效泛洪站点的信息交互的一种信息载体和标识,其相应的状态信息则表明了该泛洪MC信息的作用,如果是请求状态,则是用于请求获取相应的有效泛洪站点的信息,而如果是应答状态,则是用于相应的有效泛洪站点的信息的发布和更新。 [0047] In the present embodiment the technical solutions proposed in flooding MAC information is actually carried out and the identification information to an information carrier flooding effective interaction between the local site and remote site station edge device edge device, the corresponding state information indicates the effect of flooding MC information, if the status is requested, is used to request the information effectively flood the site, and if the state is a response, it is effective for the respective pan publish and update information flood site. [0048] (3)所述本端站点边缘设备接收所述远端站点边缘设备根据所述请求状态的所述新的业务类型的泛洪MAC信息所反馈的应答状态的所述新的业务类型的泛洪MAC信息,并根据所述应答状态的所述新的业务类型的泛洪MAC信息,在所述泛洪MAC表项中记录与该泛洪MAC地址相对应的有效泛洪站点的信息。 The [0048] (3) the present edge of the receiving end station apparatus according to the remote site edge device status request acknowledgment status new service type information feedback MAC flooding a new type of business flooding MAC information, and according to the response state of the new service type information of MAC flooding, the flood recording information corresponding to the MAC address of the active site in the flooding flooding MAC address entry .

[0049]通过本步骤的处理,将(1)中的缺省值替换为泛洪MAC信息中所提供的有效泛洪站点的信息,从而,使泛洪MAC表项中的信息得到补充和完善。 [0049] By this process step, the default value (1) replaces the site information is valid for flooding flooding the information in the MAC, whereby the information flooding MAC table entry obtained supplement and improve .

[0050] 情况二、在建立泛洪MAC表项之后的内容更新过程。 [0050] Case 2, after establishing the MAC flooding entry content update process.

[0051] (1)所述本端站点边缘设备接收所述远端站点边缘设备按照预设的发送周期,主动发送的应答状态的泛洪MC信息。 [0051] (1) The local station apparatus receiving the edge remote site edge devices according to a preset transmission period, flooding MC unsolicited information responsive state.

[0052]本步骤的处理实际上是在情况一完成的基础上进行的,如果说情况一是一种泛洪MAC表项的建立和信息完善过程,那么,当前的情况二就是对于已经完成建立和信息完善过程的泛洪MAC表项的信息更新过程,这样的过程主要是基于远端站点边缘设备所配置的业务流量转发配置的变化,或者远端站点边缘设备对于其所配置的业务流量转发配置的主动更新需要。 [0052] processing of this step is actually carried out on the basis of a complete case on the case if one is to improve the process of establishing information flooding and MAC entries, then the second is the current situation has been completed for the establishment of and flooding information update process MAC entry information perfect process, this process is mainly based forwarding configuration of the remote site edge devices configured traffic changes, or remote-site edge devices for which it is configured to forward traffic Configuring update requires active.

[0053]在本步骤中,所述预设的发送周期小于所述远端站点边缘设备上所配置的业务流量转发表项的生存时间。 [0053] In this step, the transmission period is shorter than the preset lifetime configured on the distal edge device of site traffic forwarding entry.

[0054] (2)所述本端站点边缘设备根据所述应答状态的泛洪MAC信息中所携带的业务类型信息,确定所述应答状态的泛洪MAC信息所对应的泛洪MAC地址。 [0054] (2) The local station according to the service edge device type information of the MAC flooding responsive state information carried in the determined MAC address flooding flood MAC state information of the corresponding response.

[0055]这是本端站点边缘设备的信息识别过程,需要指出的是,泛洪MAC信息中并不包括具体的泛洪MAC地址的信息,而只是包括业务类型的信息,而考虑到情况一中进行泛洪MAC 表项建立过程的时候,泛洪MAC地址和业务类型之间是一一对应的关系,所以,可以通过业务类型进行泛洪MAC地址或者相应的泛洪MAC表项的查找。 [0055] This is information for identifying the local station during edge device, it is noted that the MAC flooding information does not include information on the specific MAC address flooding, but only includes service type information, consider the case where a when the flooding MAC entry establishment procedure between flooding and MAC address is one to one relationship between the service type, it is possible to find the corresponding MAC address or flooding flooding MAC address entries through the service type.

[0056] (3)所述本端站点边缘设备根据所述应答状态的泛洪MAC信息,对所述泛洪MAC表项中所记录的与所述应答状态的泛洪MC地址相对应的有效泛洪站点的信息进行更新。 [0056] (3) the local station apparatus according to the edge information of the MAC flooding responsive state, corresponding to the effective state of the flood response the MC address of the entry in the MAC flooding recorded information flooding the site is updated. [0057]由于泛洪MAC信息中包含了远端站点边缘设备主动发送过来的有效站点信息,所以,本端站点边缘设备可以据此,对(2)中所查找到的泛洪MAC地址所对应的表项进行更新。 [0057] Because of MAC flooding information includes valid remote site station information sent from the active edge device, therefore, the local site edge device could then, for (2) in the found MAC address corresponding to the flood the entries to be updated. 从而,使本端站点边缘设备能够获知最准确的远端站点边缘设备所支持的业务信息。 Thereby, the edge of the local station apparatus can know the most accurate information service site distal edge supported by the device.

[0058]步骤S302、当所述本端站点边缘设备接收到的流量的目的MAC地址是所配置的一个泛洪MAC地址时,所述本端站点边缘设备确定该泛洪MAC地址所对应的泛洪MAC表项,并根据泛洪MAC表项中所记录的信息,将所述流量转发给该泛洪MAC地址相对应的有效泛洪站点。 [0058] Step S302, the flood when a MAC address of the destination MAC address of the local site edge device receives traffic is configured, the local station determines that flood the edge device MAC address corresponding to the pan Hung MAC entries, flood MAC based on information recorded in the entry, forward the traffic to the active site of the flood flooding corresponding MAC address.

[0059] 在具体的应用场景中,所述泛洪MAC表项中所记录的各所述泛洪MAC地址所对应的有效泛洪站点的信息中,还包括有效泛洪站点中的有效出接口信息,和/或所述泛洪MAC表项的生存时间。 Flooding the site information is valid in each of the MAC address flooding [0059] In a specific application scenario, the MAC flooding entries recorded in the corresponding, further comprising an effective active site interfaces flooding information, and the survival time and / or flooding the MAC entries.

[0060] 下面,对于上述的信息进行具体的说明: [0060] Next, the above-described information will be specifically described:

[0061] 信息A、有效泛洪站点中的有效出接口信息。 [0061] information A, the effective interface information effective flood site.

[0062] 这样的信息主要是在远端站点边缘设备中设置了具体的其所支持的业务的具体对应出接口的情况下所记录的,如果远端站点边缘设备中没有设置其所支持的某种类型的业务的具体的出接口,则该信息将不会被保存,只需要保存具体的有效泛洪站点的信息即可。 In the case [0062] Such information is mainly provided at the distal end it supports a specific site in a particular edge device corresponding to the service interface recorded if the remote site is not provided in the edge devices it supports a specific types of businesses out of the interface, then the information will not be saved, only you need to save the information to a specific effective flooding the site.

[0063] 而如果设置了这样的出接口,那么,在完成上述的步骤S302的过程中,也需要将这样的信息一并携带在所转发的流量中,具体说明如下: [0063] If such a set of interfaces, then the process is complete in step S302 described above, it is also necessary to carry such information together with the flow rate of the forwarded, as explained below:

[0064] 当所述本端站点边缘设备将所述流量转发给所述泛洪MAC地址相对应的有效泛洪站点时,所述本端站点边缘设备在转发的所述流量中携带所述有效泛洪站点中的有效出接口信息,以使所述远端站点边缘设备能够根据所述有效泛洪站点中的有效出接口信息确定转发所述流量的转发接口。 [0064] When the local site edge device forwards the traffic to the active site of the flood flooding corresponding MAC address, the edge device of the local station carries the valid forwarding the traffic in effective interface information flooding the site, so that the remote station is able to forward forwarding interface edge device based on the flow rate of the active interface information flooding the active site is determined.

[0065] 信息B、生存时间。 [0065] The information B, the survival time.

[0066] 这主要是为了实现所建立的泛洪MAC表项的老化,避免保存不必要的泛洪MAC表项而造成的存储资源的浪费以及业务转发的混乱,避免出现远端站点边缘设备已经不再继续支持某种类型的业务,但因为相应的泛洪MC表项未被老化,而导致流量的无效转发。 [0066] This is mainly to achieve the aging flood MAC table entries established, avoid saving unnecessary flooding MAC entry and storage resource waste caused confusion and forwarding business, to avoid the remote site equipment has been around the edge no longer continue to support some type of business, but because of flooding MC corresponding entry is not aging, resulting in invalid traffic forwarding.

[0067] 具体的,当所述本端站点边缘设备判断一个或多个泛洪MAC表项所对应的生存时间为〇时,所述本端站点边缘设备删除所述一个或多个泛洪MC表项。 [0067] Specifically, when the local station edge device determines the one or more MAC entries flooding survival time corresponding square, the edge of this end station device deletes the one or more flood MC entries.

[0068]当然,对于一个泛洪MAC表项的生存时间,可以通过上述的步骤S301中的情况二进行更新,保证相应的生存时间与远端站点边缘设备中的生存时间相匹配,在远端站点边缘设备能够支持某种类型的业务的时候,始终保证相应的表项在本端站点边缘设备中得以保存,并进一步保证相应类型的流量能够及时的转发给相应的远端站点边缘设备。 [0068] Of course, for a MAC flooding survival time entries can be updated by the above-described step S301 where the two, to ensure the survival time corresponding to the remote site and the survival time of the device matches the edge, at the distal end site edge equipment capable of supporting some type of business, when, always ensure that the appropriate entries are saved in the local site edge devices, and further ensure the appropriate types of traffic can be forwarded promptly to the corresponding edge of the remote site equipment.

[0069]由以上的说明可以看出,本端站点边缘设备是一个保存泛洪MAC表项并进行流量转发的站点,而远端站点边缘设备则是支持某种类型的业务,并进而成为该流量的泛洪目的端的站点,但是,在具体的应用场景中,这样的身份定位是可以互换的,即在上述的描述过程中,远端站点边缘设备是该本端站点边缘设备的某种业务的泛洪目的端,而本端站点边缘设备同时也是该远端站点边缘设备的某种业务的泛洪目的端。 [0069] As can be seen from the above description, the present apparatus is a terminal site edge stored MAC flooding and traffic forwarding entry site, while the distal site is the edge devices support some type of business, and thus become the flooding traffic to the destination end station, but in a specific application scenario, the identity of such positioning are interchangeable, i.e., in the above-described process, the remote station is some kind of edge of the device of the present apparatus side edge site flooding traffic destination, while the end of the present device is also the site edge certain service site distal edge device flood destination.

[0070]在此种情况下,本端站点边缘设备中配置了包含一种或多种业务类型的业务流量的转发接口的业务流量转发表项,相应的,所述方法还包括以下的三种处理过程: [0070] In this case, the local station edge device configured traffic comprises one or more types of service interfaces forwarding traffic forwarding entries, accordingly, the method further comprises the following three process:

[0071 ] (1)与上述的步骤S301中的情况一相对应的泛洪MAC信息的应答过程。 [0071] (1) the above-described step S301 corresponds to a case where the response information MAC flooding process.

[0072] 当所述本端站点边缘设备接收到远端站点边缘设备发送的携带请求状态的一个业务类型的泛洪MAC信息时,所述本端站点边缘设备判断所述泛洪MAC信息所对应的业务类型是否与本地所配置的转发接口所对应的业务类型相匹配。 [0072] When the local site edge device receives a MAC flooding traffic type information carried in the request sent by the remote site status edge device, the edge device of the local station to determine whether the information corresponding to the MAC flooding whether the type of service configured to forward the local traffic interface corresponding to the type of match.

[0073] 如果判断结果为是,所述本端站点边缘设备向所述远端站点边缘设备发送携带应答状态的所述业务类型的泛洪MAC信息的消息,以使所述远端站点边缘设备根据所述携带应答状态的所述业务类型的泛洪MAC信息,在相应的泛洪MAC表项中将所述本端站点边缘设备的信息记录为有效泛洪站点的信息,其中,所述携带应答状态的所述业务类型的泛洪MAC 信息包括有效出接口信息。 [0073] If the judgment result is positive, the local site edge device sends a message to the service type of MAC flooding acknowledgment status information is carried to the edge device remote site, the remote site such that the edge device according to the service type information of the MAC flooding carried responsive state, the corresponding edge of the information recording apparatus of the entries in the MAC flooding the local site for effective flood the site information, wherein said carrier the service type information response MAC flooding active state includes the interface information.

[0074] (2 )与上述的步骤S301中的情况二相对应的主动的泛洪MAC信息的更新过程。 [0074] (2) the above-described step S301 corresponds to the case of two active MAC flooding update process information.

[0075]当达到预设的发送周期时,所述本端站点边缘设备根据自身配置的当前处于有效状态的业务流量的转发接口,分别向各远端站点边缘设备主动发送应答状态的泛洪MAC信息,以使所述远端站点边缘设备根据所述泛洪MAC信息,在相应的泛洪MAC表项中对有效泛洪站点的信息进行更新。 [0075] When predefined transmission cycle, the local station edge device is in its configuration according to the current traffic flow forwarding interface active state, respectively, each edge device sends the remote site responsive state MAC flooding information, so that the remote station apparatus according to the edge information of MAC flooding, flooding the site information effectively updated in the corresponding entry MAC flooding.

[0076] (3)与上述的步骤S302中的情况相对应的流量接收过程。 [0076] (3) the above-mentioned step S302 in the case where the process corresponding to the received traffic.

[0077] 当所述本端站点边缘设备接收到远端站点边缘设备根据相应的泛洪MAC表项中所记录的有效泛洪站点的信息所转发的流量时,所述本端站点边缘设备获取所述流量中携带的有效出接口信息,并通过相应的相应的出接口进行所述流量的转发。 [0077] When the local station to the remote station receives the edge device edge device based on the information forwarded by flooding the site corresponding to the effective flood MAC entry recorded in the traffic, said edge device acquires the local station the active outbound interface information carried in the traffic, and forwards the traffic out of the respective through respective interfaces.

[0078] 需要说明的是,如果本端站点边缘设备中只是设置了其所支持的业务类型所对应的业务流量转发表项,即表明自身是某种业务类型的流量的泛洪目的端,那么,在上述的(3)中,便不存在对应的出接口的处理过程,这样的变化并不会影响本发明的保护范围。 [0078] It should be noted that, if the local site edge devices just set the type of business it supports the corresponding traffic forwarding entry, which indicates the destination itself is a flood of traffic to some type of business, then in the above-described (3), the process corresponding to the interface would not exist, this change does not affect the scope of the present invention. [0079]下面,结合具体的应用场景,对本发明实施例所提出的技术方案进行说明。 [0079] Next, with reference to specific application scenario, the proposed technical solutions of the present invention will be described.

[0080] 在本应用场景中,所提出的技术方案用于实现EVI网络中业务流量按需向特定站点的某个接口进行泛洪,至于按需向特定站点进行泛洪的情况,与此类似,在此不再重复说明。 [0080] In this application scenario, the proposed technical solution for realizing the traffic demand to flood an interface to a specific site EVI network, as needed flooding situation to a specific site, similar to this and will not be repeated here.

[0081] 如图4所示,为本发明实施例所提出的一种具体应用场景下的业务流量的泛洪方法的流程示意图,该方法具体包括以下步骤: [0081] As shown in FIG 4, a schematic flow chart of the method of flooding traffic in a specific application scenario according to the proposed embodiment of the invention, the method includes the following steps:

[0082]步骤S401、在本端站点边缘设备的EVI隧道下配置业务流量转发到远端设备所需的泛洪MAC地址,并建立相应的泛洪MAC表项。 [0082] step S401, the EVI at the site of a tunnel edge device configured to forward traffic to the desired MAC address flooding remote device, and establish the corresponding MAC entries flooding.

[0083] 具体的,可建立如表1所示的EVI泛洪MAC表项。 [0083] Specifically, the flooding may be established EVI MAC entries as shown in Table 1.

[0084] 表1EVI泛洪MAC表项 [0084] MAC table entries 1EVI flooding

Figure CN103414634BD00101

[0086]其中,各字段的含义说明如下: [0086] wherein the meaning of each field is as follows:

[0087]泛洪MAC地址:指出转发业务流量所需的泛洪MAC地址。 [0087] flood MAC Address: Indicates required to forward traffic flooding MAC address. 例如,DHCPv6协议报文转发时,需要使用泛洪MAC地址3333-0001-0002,而VRRP协议报文转发时,需要使用泛洪MAC地址0100-5e00-0012〇 For example, when the DHCPv6 protocol packet forwarding, flooding required MAC address 3333-0001-0002, while the VRRP packet forwarding, MAC address flooding required 0100-5e00-0012〇

[0088] VLAN:指出可在哪个VLAN内进行泛洪,可以是一个VLAN范围。 [0088] VLAN: flooding can be pointed out in which VLAN, VLAN can be a range.

[0089] 业务标识:标识是哪种业务类型的业务流量。 [0089] service identity: what kind of business to identify the type of traffic.

[0090] 有效泛洪站点:能够提供相应的业务类型的服务的站点,通过EVI-ISIS (Intermediate System to Intermediate System,中间系统到中间系统)通告报文学习得至Ij,也就是报文中的system id(系统标识)字段。 [0090] Effective flood site: to provide a corresponding service types of sites and services, by EVI-ISIS (Intermediate System to Intermediate System, Intermediate System to Intermediate System) Acquisition Literature advertisement message to Ij, i.e. packets system id (system identification) field.

[0091] 有效出接口索引:能够提供业务流量的站点上提供业务的具体接口索引。 [0091] an effective interface index: index provides an interface capable of providing specific services on site traffic. 即如该接口下下挂了服务(如DHCPv6服务器),就是那个接口的索引,可以通过EVI-ISIS通告报文学习得到,实现的时候需要在EVI-ISIS通告报文中新增option(选项)字段,用于携带这个信息。 That is, if it is a hang-interface service (such as a DHCPv6 server), is an index that interface, you can notice packet learning by EVI-ISIS get, when you need to achieve in the EVI-ISIS advertisement packet new option (option) field used to carry this message.

[0092] Lifetime(生存时间):泛洪MAC地址即该泛洪MAC表项的有效生存时间,也是通过EVI-ISIS通告报文的新增option字段中携带这个信息。 [0092] Lifetime (Time to Live): i.e., the MAC address flood valid lifetime flood MAC entry, this information is carried by a new option field EVI-ISIS advertisement packet in.

[0093] 在上述的表1中,NA表示前述的缺省值,既没有明确具体的有效泛洪站点的信息, 在使用缺省值的过程中,如果收到目的MAC地址为泛洪MAC地址的报文,默认向所有站点进行泛洪。 [0093] In the above Table 1, NA represents the default value is neither clear and specific information is valid flooding site during use of the default value, if the received destination MAC address is the MAC address flooding message, the default flooding to all sites.

[0094] 具体的,上述的新增Option字段,可命名为EVI selective-flooding for server option(基于服务的EVI泛洪选项),并约定为OptionlOO字段,具体格式如表2所示: [0094] Specifically, the above-described new Option field, can be named as EVI selective-flooding for server option (option based on EVI flooding and services), and agreed to OptionlOO field, particularly the format as shown in Table 2:

[0095] 表20ption100 字段及其说明 [0095] Table fields and their descriptions 20ption100

Figure CN103414634BD00111

[0097]其中,需要说明的是,具体的出接口信息可以使用上述的接口索引(Interf ace)来代替,例如:使用gl/0/l所对应的接口索引〇〇〇1,这是为了节省存储比特数。 [0097] wherein Incidentally, the specific interface information may be used the above-described interface index (Interf ace) instead, for example: using the interface index 〇〇〇1 gl / 0 / l corresponding to this is to save the number of bits stored.

[0098]具体的,当第一次进行一个泛洪MAC地址配置时,相应的有效泛洪站点的信息都是缺省值,为了对相应的信息进行更新,本端站点边缘设备在接下来的3个EVI-ISIS通告报文(在具体的应用场景中可以根据实际需要进行具体报文个数的设置,这样的变化并不会影响本发明的保护范围)中会携带上述的新增的OptionlOO字段(即上述的Option字段的一种具体形式),在该OptionlOO字段中,Option Code是Request(即前述的请求状态),表示请求远端站点边缘设备告知该业务类型的业务流量所对应的有效泛洪站点的各种信息。 [0098] Specifically, when the first time a MAC address configuration flood, flooding significance information corresponding site are the default values, for the corresponding information is updated, the edge device in the local site next 3 EVI-ISIS advertisement message (can be set specific number of packets in accordance with the actual needs of the specific application scenario, such a change does not affect the scope of the present invention) will be carried above the new OptionlOO field (i.e., a specific form of the above-described Option field), the field OptionlOO, a Code Option request (i.e., the state of the request), the request indicates the remote site service edge device informing the traffic type corresponding to the effective a variety of information flooding the site.

[0099]步骤S402、根据具体的需求,在能够提供相应业务类型的业务的远端站点边缘设备中配置相应的业务流量转发表项,其中包括指导业务流量转发的具体的出接口,并将此信息携带在EVI-ISIS通告报文的optionlOO字段中,发送给本端站点边缘设备(对该远端站点边缘设备而言的远端站点边缘设备)。 [0099] step S402, according to specific needs, can be provided arranged on respective type of service traffic distal edge device corresponding site traffic forwarding entries, including an interface to the specific forward traffic guidance, and this optionlOO information is carried in the field EVI-ISIS advertisement packets and send them to the local site edge device (the remote site to the edge device in terms of edge device remote site).

[0100] 其中,远端站点边缘设备上建立的业务流量转发表项具体如表3所示: [0100] The established on the distal edge device of site specific traffic forwarding entry in Table 3:

[0101] 表3业务流量转发表项 [0101] Table 3 traffic forwarding entry

Figure CN103414634BD00121

[0103] 具体的,上述的optionlOO字段的通告周期可自行设置,但必须小于表2中相应的lifetime值,这是为了防止业务的生存时间到了,却没有通告给本端站点边缘设备(对当前远端站点边缘设备而言的远端站点边缘设备)更新相应的lifetime,本端站点边缘设备因此而在I if et ime归零时老化了对应的泛洪MAC表项。 [0103] Specifically, the above-described advertisement period optionlOO field may set their own, but the corresponding lifetime value 2 must be less than the table, this is to prevent the survival time of traffic to, but did not notice This end edge device of site to the (current For remote site remote site edge device edge device) to update the corresponding lifetime, the local station and thus the edge device aging flooding MAC address entries in the I if et ime zero.

[0104] 进一步的,在具体的应用场景中,可以在EVI-ISIS的通告的HELLO报文中携带上述的信息,即使用新增的OptionlOO字段。 [0104] Further, in a specific application scenario, may carry the above-mentioned information HELLO packet advertised EVI-ISIS, i.e., use the new OptionlOO field.

[0105]步骤S403、本端站点边缘设备在接收到EVI-ISIS协议报文后,检查是否携带有optionlOO 字段。 [0105] step S403, the edge device of the local station after receiving the EVI-ISIS protocol packets, checking whether the carrying optionlOO field.

[0106]如果不存在,则根据具体的规则对该EVI-ISIS协议报文进行相应的报文处理。 [0106] If not present, according to a specific rule corresponding to the message processing EVI-ISIS protocol packets. [0107]如果存在,则进一步根据其中携带的相应的OptionlOO字段,对本地保存的相应的泛洪MAC表项进行处理。 [0107] If present, which is further in accordance with the respective field carries OptionlOO, flooding the corresponding MAC entries locally stored for processing.

[0108]具体的,本端站点边缘设备解析optionlOO字段中的内容,如果其Optioncode的内容是reply(即前述的标识为应答状态),则将相应的内容提取出来并,更新之前生成的泛洪MAC表项中对应的信息。 [0108] Specifically, the contents of the local site edge device parses optionlOO field, if the content thereof is Optioncode Reply (i.e., identified as the response state), the corresponding content is extracted and generated before the update flooding the MAC table entry corresponding.

[0109] 首先,判断OptionlOO字段中的Server Type(业务类型)的内容所对应的业务类型是否在本地保存的泛洪MAC表项中存在,如果存在,继续处理,否则,丢弃此报文(表示本端站点边缘设备并不需要转发此业务类型的流量,业务流量的业务类型一般与泛洪MAC地址是对应的关系)。 [0109] First, it is determined OptionlOO field Server Type (service type) of the content corresponding to the service type is stored in a local flooding MAC address entry is present, if present, processing continues, otherwise, discards this packet (represented this device does not require an edge end station forwards the traffic service type, service type traffic of ships and flooding relationship corresponding to the MAC address).

[0110]在具体的应用场景中,上述的继续处理的处理过程具体如下: [0110] In a specific application scenario, processing continues in the above-described process as follows:

[0111 ] 进一步,判断Option字段中携带的system id与本地所保存的泛洪MAC表项中所保存的有效泛洪站点是否相同。 [0111] Further, the Option field determination system id carried in the local MAC flooding stored entries saved in the same active site is flooded.

[0112] 如果相同,则更新该泛洪MAC表项,相应的出接口和I if etime都可能更新,而如果不相同,则表示该泛洪MAC表项中当前不存在相应的站点,从而,添加该站点为该业务类型所对应的另一个有效泛洪站点,相应的出接口和I ifetime也进行添加。 [0112] If the same, then updating the flooding MAC entry, the outgoing interface and I if etime may update, and if not identical, then the corresponding site of the flood MAC address entry does not currently exist, so that, add the active site for further flooding the site corresponding to the service type, and the outgoing interface I ifetime also added.

[0113] 下面,通过不同的情况,对本发明实施例所提出的上述的进行泛洪MAC表项进行更新的过程在不同情况下的应用过程进行说明: Process [0113] Next, in different circumstances, the above-described MAC flooding embodiment of the proposed entry is updated embodiment of the present invention will be described in the application process under different circumstances:

[0114] 情况一,原泛洪MAC表项中不存在有效泛洪站点(即相当于前述的初始建立泛洪MAC表项的情况)。 [0114] a case, the original MAC flooding there is no valid entry flooding the site (i.e., corresponding to the case of establishing the initial flooding MAC entries).

[0115] 如果本端站点边缘设备收到携带如下所示的OptionlOO字段的报文,且EVI-ISIS 报t中svstem id=l: [0115] If the local station edge device receives the packets carry OptionlOO fields as shown below, and the EVI-ISIS packets t svstem id = l:

Figure CN103414634BD00131

LUll/J 则表不该OptionlOO子段为应眢状态,开M,Server type中0x0001表不UHCPv6的业务类型,该业务类型在当前本地保存的泛洪MAC表项中存在,且该泛洪MAC表项中,并没有存储相应的有效泛洪站点的信息,所以,本端站点边缘设备根据上述的OptionlOO字段的信息,将本地保存的如下所示的原始泛洪MC表项: LUll / J OptionlOO the sub-segment of the table should be parched state, the opening M, Server type 0x0001 in the table is not UHCPv6 service type, service type that exists in the current MAC flooding locally stored entry, and the MAC flooding entry, the corresponding information is not stored effectively flood the site, therefore, the original MC flooding the local station apparatus according to the edge information of the field of OptionlOO, locally stored entries shown below:

Figure CN103414634BD00132

[0121] 情况二、原泛洪MAC表项中存在有效泛洪站点(即相当于前述的泛洪MAC表项建立完成并填充了缺省值之后,进行信息更新的情况)。 [0121] Case 2, there is a valid entry site flooding Central Plains flooding MAC (i.e., corresponding to the after flooding and MAC entry setup complete filling a default value, a case where the updated information).

[0122] 如果本端站点边缘设备收到携带如下所示的OptionlOO字段的报文,且EVI-ISIS 报文中system id=l: [0122] If the local station edge device receives the packets carry OptionlOO fields as shown below, and the packets of EVI-ISIS system id = l:

Figure CN103414634BD00133

Figure CN103414634BD00141

[0124] 则表示该OptionlOO字段为应答状态,并且,Server type中0x0001表示DHCPv6的业务类型,该业务类型在当前本地保存的泛洪MAC表项中存在,且该泛洪MAC表项中以及存储了一个有效泛洪站点的信息,经过比对可以发现,相应的有效泛洪站点一致,而有效出接口索引并不一致,所以,本端站点边缘设备需要为该泛洪MAC地址添加一个新的有效泛洪站点的信息,所以,根据上述的OptionlOO字段的信息,将本地保存的如下所示的原始泛洪MAC 表项: [0124] indicates that the OptionlOO field response state, and, Server type of 0x0001 indicates DHCPv6 service type, the service type is present in the current locally stored flooding MAC address entry, and the flooding MAC address entry and storing a new active site an effective flood pan information, after comparison can be found, the corresponding valid consistent flooding the site, while the effective index of the interface is not uniform, so the edge of the local station apparatus to add the MAC address for flooding flooding the site information, so according to the information of the OptionlOO fields, the original MAC flooding locally stored entries shown below:

Figure CN103414634BD00142

[0128] 情况三,EVI-ISIS报文中携带的system id与MAC表中有效泛洪站点不相同,说明该OptionlOO字段来自另一个站点,因此,需哟添加一条新的泛洪MC表项 [0128] three cases, system id and table EVI-ISIS MAC packet carried in the active site does not flood the same, indicating that the OptionlOO fields from another site, therefore, a need to add new yo MC entries flooding

[0129] 本端站点边缘设备收到携带如下所示的OptionlOO字段的报文,且EVI-ISIS报文中system id=2: [0129] The local station edge device receives the packets carry OptionlOO fields as shown below, and the packets of EVI-ISIS system id = 2:

Figure CN103414634BD00143

[0131] 则表示该OptionlOO字段为应答状态,并且,Server type中0x0001表示DHCPv6的业务类型,该业务类型在当前本地保存的泛洪MAC表项中存在,但是相应的有效泛洪站点是system ID=I的站点,与OptionlOO所对应的站点不同,因此,在该泛洪MAC表项中,并没有存储本OptionlOO所对应的有效泛洪站点的信息,所以,本端站点边缘设备根据上述的OptionlOO字段的信息,将本地保存的如下所示的原始泛洪MAC表项: [0131] indicates that the OptionlOO field response state, and, Server type of 0x0001 indicates DHCPv6 service type, the service type is present in the current locally stored flooding MAC table entry, the corresponding effective flood site the system ID = I site, and OptionlOO the corresponding site different, and therefore, the flooding MAC table entry, and no information is valid flooding sites storing this OptionlOO corresponds, therefore, the local site edge apparatus according to the above-described OptionlOO information fields, the original MAC flooding entries locally stored as shown below:

Figure CN103414634BD00151

[0135] 步骤S404、当本端站点边缘设备收到目的MAC地址是本地保存的泛洪MAC地址的流量,则根据泛洪MC表项,将该流量泛洪到对应的远端站点边缘设备。 [0135] step S404, the local station when the edge device receives the destination MAC address is stored locally flooding traffic MAC address, according to the entry MC flooding, the flood traffic to remote sites corresponding edge device.

[0136] 结合前述的表项内容说,以下的泛洪MAC表项表示,本端站点边缘设备收到目的MAC地址是3333-0001-0002的DHCPv6业务流量时,则向远端站点边缘设备1的出接口索引为0001的接口方向进行泛洪,远端站点边缘设备1设备收到此报文后,并进行隧道解封装后, 根据接口索引0001将该报文转发到gl/0/l接口。 [0136] The aforementioned incorporated entry that the entry of MAC flooding, said edge device receives the local station is the destination MAC address 3333-0001-0002 DHCPv6 traffic, the edge of a device to a remote site outbound interface index for the interface 0001 of the direction of flooding, the distal edge device station apparatus 1 after receiving the packet, and decapsulates the tunnel, according to the 0001 interface index forwards the packet to gl / 0 / l Interface .

Figure CN103414634BD00152

[0138]需要指出的是,为了清楚的标识出接口的信息,本端站点边缘设备经EVI隧道进行转发的报文中添加一个Interface id选项,标记需要转发到远端站点边缘设备的出接口, 远端站点边缘设备收到此报文,并进行隧道解封装后,可以解析得到出接口索引,从而,直接找到对应的出接口,将解封装后的报文转发出去。 [0138] It is noted that, for clarity of the information identifying the interface, the local station for an edge device Interface id options added to the packets forwarded through the tunnel EVI, tags need to be forwarded to an edge device interfaces the remote site, site distal edge device receives the packet, and decapsulates the tunnel, an interface index obtained can be resolved, thereby, directly to the corresponding outgoing interface, packets decapsulated forwarded.

Figure CN103414634BD00153

[0140]在本发明实施例所提出的技术方案中,lifetime的作用主要是为了对泛洪MAC表项进行老化和更新。 [0140] In the embodiment of the present invention, the technical solutions proposed, lifetime effects of flooding mainly to aging and MAC entries updated. 这是为了更灵活的适应站点内以及站点间服务器的迀移。 This is to adapt to the site within a more flexible and Gan inter-site server shift.

[0141] 下面,通过具体的示例对相应的应用过程进行说明: [0141] The following description of the corresponding application process by way of specific examples:

[0142] 情况一: [0142] Case 1:

[0143] 远端站点边缘设备1上g 1 /0/1接口下挂的DHCPv6服务器被迀移到的别的接口g 1 / 0/2,业务流量就不必再发往gl/0/l了,此时,需要把本端站点边缘设备上保存的与gl/0/l 相对应的泛洪MAC表项老化删除。 [0143] edge device on the remote site linked to a G DHCPv6 server is moved to the other interfaces Gan g 1 / 0/2, you do not have to send traffic to gl / 0 / l under 1/0/1 in this case, the need to save on the edge device and the local station gl / 0 / l corresponding MAC flooding delete entries age. 具体的过程如下: Specific process is as follows:

[0144] 由于在远端站点边缘设备1上已经不再有gl/0/l相对应的业务流量转发表项(可以是在发生服务器迀移时主动删除,也可以是随着相应的业务流量转发表项的lifetime归零而被删除),因此,远端站点边缘设备1也不会主动发送对应于gl/0/l的OptionlOO字段对本端设备相应的泛洪MAC表项中的信息进行更新,那么,本端站点边缘设备所保存的泛洪MAC表项中与gl/0/l相对应的lifetime也会慢慢归零,本端站点边缘设备也会在其归零后, 对相应的泛洪MAC表项进行删除。 [0144] Since the sites on the distal end edge of the device 1 there is no longer gl / 0 / l corresponding to the traffic forwarding entries (the server may be automatically deleted Gan shift occurs, as may be the corresponding traffic forwarding entry is deleted lifetime zero), therefore, the remote site is not an edge device sends corresponding to gl / 0 / l of the corresponding information field OptionlOO local flooding device MAC address entry is updated , then the local site edge devices stored flooding and MAC address entry gl / 0 / l corresponding lifetime will gradually to zero, the local station after its edge device also zero, the corresponding flooding MAC entries were deleted.

[0145] 可以用以下的例子说明: [0145] can be illustrated by the following examples:

[0146] 由于本端站点边缘设备没有接收到对应于有效出接口索引0001 (表示接口gl/0/ 1)的新的〇Pt ion 100字段,因此,I if et ime不会更新,只会慢慢归零,具体如下所示: [0146] Since the end station device does not receive an edge corresponding to an effective index of the interface 0001 (represented by the interface gl / 0/1) of the new field 〇Pt ion 100, therefore, I if et ime not updated, only slowly slow to zero, as shown below:

[0150] 情况二: [0150] Case 2:

[0151] 远端站点边缘设备1上gl/0/l接口下挂的DHCPv6服务器被迀移到的站点2接口gl/ 0/1,业务流量就不必再发往站点1的gl/0/l了,此时,需要把本端站点边缘设备上保存的与远端站点边缘设备1的gl/0/l相对应的泛洪MC表项老化删除。 [0151] Sites on the distal edge of the hanging device 1 gl / 0 / l interfaces DHCPv6 server site 2 is moved to the interface Gan gl / 0/1, do not have to send traffic to sites gl / 0 1 is / l , this time, the need to save on the local site and the remote site edge device edge device 1 gl / 0 / l corresponding flooding MC delete entries age. 具体的过程如下: Specific process is as follows:

[0152] 由于在远端站点边缘设备1上已经不再有DHCPv6业务相对应的业务流量转发表项(可以是在发生服务器迀移时主动删除,也可以是随着相应的业务流量转发表项的lifetime归零而被删除),因此,远端站点边缘设备1也不会主动发送对应于DHCPv6业务的OptionlOO字段对本端设备相应的泛洪MAC表项中的信息进行更新,那么,本端站点边缘设备所保存的泛洪MAC表项中与远端站点边缘设备1相对应的lifetime也会慢慢归零,本端站点边缘设备也会在其归零后,对相应的泛洪MAC表项进行删除。 [0152] Due to the remote site on the edge of the device 1 is no longer there DHCPv6 services corresponding to traffic forwarding entries (can be automatically deleted when the server Gan shift occurs, it can be with the appropriate traffic forwarding entry lifetime of zero is deleted), and therefore, the remote site is not an edge device sends DHCPv6 service corresponding to the information field OptionlOO respective local flooding device MAC address entry is updated, then the local site the edge device stored flooding will gradually MAC address entry corresponding to the zero and an edge device lifetime remote site, the local site after its edge device also zero, the corresponding MAC entries flooding be deleted.

[0153] 可以用以下的例子说明: [0153] can be illustrated by the following examples:

[0154] 由于本端站点边缘设备没有接收到对应于有效泛洪站点1 (表示远端站点边缘设备1)的新的Opt ion 100字段,因此,I if et ime不会更新,只会慢慢归零,具体如下所示: [0154] Since the end station device does not receive an edge corresponding to an active site flooding (represented distal edge device of site 1) of the new field Opt ion 100, therefore, I if et ime not updated, only slowly zero, shown as follows:

Figure CN103414634BD00171

[0156]而当lifetime减为0后,该条表项就被本端站点边缘设备删除,相应的泛洪MAC表项更新如下,已经对远端站点边缘设备1所对应的泛洪MC表项进行了老化。 [0156] When the lifetime is reduced to 0, the entry is deleted piece of the local site edge equipment, the corresponding MAC entries flooding updated as follows, the remote site has the edge device corresponding to the entries 1 MC flooding It was aging.

Figure CN103414634BD00172

[0158] 由此可见,当本端站点边缘设备一直没有收到更新对应泛洪MAC表项的OptionlOO 时,I if etime会慢慢归零,而本端站点边缘设备也会在I if etime过期后,将对应的泛洪MAC 表项删除。 [0158] Thus, when the local station does not receive an edge device updates the corresponding entry in the MAC flooding OptionlOO, I if etime slowly to zero, and the local station in the edge device will expire I if etime after flooding the corresponding MAC entries deleted.

[0159] 进一步的,在具体的应用场景中,为了实现更好地提醒效果,可以约定在lifetime 减少到一半时间后,如果此时有EVI-ISIS HELLO报文发送,则主动携带optionlOO字段, option code为请求(标识为请求状态),请求更新相应的lifetime值,在规定的时间内,如果没有收到应答,则本端站点边缘设备可立即将对应的泛洪MAC表项删除,这样,又能减少流量的不必要泛洪。 [0159] Further, in a specific application scenario, in order to achieve better results alert may be specified in half the time after the reduced lifetime, if at this time there EVI-ISIS HELLO packets, carrying the active optionlOO field, option code request (request status is identified), a request to update the corresponding lifetime values ​​within a predetermined period of time, if no response is received, the device may present the end edge of the site instantly MAC flooding delete the corresponding entry so that they You can reduce the flow of unnecessary flooding.
