Description

分布式网络处理系统的MAC地址表项信息同步方法及装置 MAC address entries synchronization method and apparatus for a distributed network of processing systems

技术领域 FIELD

[0001] 本发明涉及通信技术领域,尤其涉及一种分布式网络处理系统的MAC(Media Access Control,媒体接入控制)地址表项信息同步方法及装置。 [0001] The present invention relates to communication technologies, and particularly to a distributed network of processing systems MAC (Media Access Control, media access control) address entries synchronization method and apparatus.

背景技术 Background technique

[0002] 分布式网络处理系统如分布式网桥,用来将相互隔离的各个本地区域网络连接为一个局域网,并进行各区域网络间的业务报文传输。 [0002] distributed processing system such as distributed network bridge, for each of the mutually isolated connection to a local area network LAN, and packet transmission service among the LAN. 业务报文的传输需要依据业务报文的MAC地址,以及业务处理板的MAC地址表项信息来实现。 Service message transmissions required to implement a MAC address based on the service packet, and the MAC address entries LPU. 业务报文的MAC地址包含源地址和目的地址,MAC地址表项信息记录了MAC地址与业务处理板的端口的对应关系。 MAC address of the service packet contains a source address and a destination address, MAC address table records correspondence between the MAC address and port LPU.

[0003] 在业务报文传输时,根据业务报文的目的MAC地址,查找与该目的MAC地址对应的MAC地址表项信息,得到对应的出端口信息,将业务报文转发出去。 [0003] When the text message transmission services, according to the MAC address of the service packet, looks up the MAC address entries corresponding to the destination MAC address, to give the corresponding port information, packet forwarding traffic out. 同时学习或更新与源MAC地址的对应的MAC地址表项信息;并将每次学习到的MAC地址表项信息向其它业务处理板广播,然后各业务处理板进行该MAC地址表项信息的学习。 While learning or updating MAC address entries corresponding to the source MAC address; and each learned MAC address entries, and each service processing board of the MAC address entries to other learning broadcast LPU .

[0004] 但是该广播完成以后,各业务处理板分别对各自的MAC地址表项信息进行维护, 和老化,所谓老化,即按照一定的规则将不匹配的MAC地址表项信息删除。 [0004] After the broadcast is completed, however, each service processing board each respective MAC address entry information is maintained, and aging, so-called aging, i.e., the MAC address entry information according to certain rules that do not match will be deleted. 因此,各业务处理板的MAC地址表项信息会出现不同步,有时,MAC地址表项信息的不同步会产生诸多问题,例如,业务处理板1和业务处理板2均存有同一MAC地址表项信息,当业务报文一直经过业务处理板1转发时,业务处理板2会因老化时间内未接收到该MAC地址的业务报文,而将该MAC地址表项信息老化删除,当业务报文迁移至业务处理板2进行转发时,因业务处理板2中相应的MAC地址表项信息已经删除,此时业务处理板2还需要再进行该MAC地址表项信息的学习,并向其它业务处理板进行广播。 Thus, the MAC address entry information of each service processing boards will not synchronized, and sometimes, no synchronization problems occur MAC address entries, e.g., service processing and service processing plate 1 plate 2 there are the same MAC address table item information, when the service packet has been forwarded through an LPU, the LPU 2 due to the aging time is not received service packet with the MAC address, and the MAC address aging entries deleted, when a service packet migrate to the text when forwarding service processor card 2, because a corresponding 2 MAC address entries deleted LPU LPU case 2 still need to learn the MAC address entry information, and other services broadcast processing board. 这样由于各业务处理板中MAC地址表项信息的不同步,产生了大量的广播处理现象,导致了网络处理系统转发性能和效率的下降,破坏了数据传输的连续性。 Since this is not synchronized each service processing board MAC address entries, resulting in a large number of broadcast processing, which cause decreased forwarding network processing system performance and efficiency, destroyed continuity of data transmission.

[0005] 现有技术中采用了包括一个接口板和多个业务处理板的分布式网络处理系统来进行同步,接口板将业务报文转发到业务处理板后,业务处理板都将每次学习到的MAC地址表项信息广播到接口板及其它所有业务处理板中,然后通过接口板来集中维护各业务处理板中MAC地址表项信息的老化,即在接口板中设置老化时间,若在老化时间内接收到相应的业务报文,则对相应的MAC地址表项信息进行更新,即重新初始化MAC地址表项中的老化时间,否则,删除接口板及各业务处理板中相应的MAC地址表项信息。 [0005] The prior art uses a distributed network processing system comprises a plurality of interface board and the LPU to synchronize, the interface board will forward the service message to the LPU, the LPU will learn each MAC address entries broadcast to the interface board and all other service processing board, and then concentrated via the interface board to maintain the aging of each service processing board MAC address entries, i.e., the aging time of the interface board, if the receive the corresponding service packet, then the corresponding MAC address entries for updating the aging time, i.e. aging time reinitialize the MAC address table entry, otherwise, delete the interface board and each service processing board corresponding MAC address entries.

[0006] 在实现本发明的过程中,发明人发现现有技术至少存在以下问题:将每次学习的MAC地址表项信息都广播至所有业务处理板,不仅使同步的效率降低,而且MAC地址表项信息占用了各业务处理板的大量空间。 [0006] During the implementation of the present invention, the inventors found that the prior art has at least the following problems: MAC address of each entry information are broadcasted to all learning LPU not only reduce the efficiency of synchronization, and the MAC address entries take up a lot of space each LPU.

[0033] 为了使本领域技术人员能进一步了解本发明的特征及技术内容,请参阅以下有关本发明的详细说明与附图,附图仅提供参考与说明,并非用来限制本发明。 [0033] In order that those skilled in the art to further understand features and technical contents of the present invention, please see the following detailed description and appended drawings of the present invention, with reference to the accompanying drawings and description only and is not intended to limit the present invention.

[0034] 下面结合附图和实施例,对本发明实施例的技术方案进行描述。 [0034] accompanying drawings and the following embodiments, the technical solutions of the embodiments of the present invention will be described.

[0035] 当设备或局域网之间制定了某种业务,通过分布式网络处理系统进行基于该业务的业务报文传输,如图1所示,在该业务报文的传输过程中,该分布式网络处理系统分别连接有设备或网络,该分布式网络处理系统内存在该业务的业务配置信息,包括:接收业务报文和发送业务报文经过的业务处理板信息、端口信息以及该端口所在的LAG(Link Aggregation Group,链路聚合组)组端口信息,业务承载的MPLS (Multi-Protocol Label Switching,多协议标签交换)隧道信息,业务的VSI (Virtual Service instance,虚拟服务实例)信息,业务使用VLAN(Virtual Local Area Network,虚拟局域网)的信息,业务的MAC地址老化时间信息等。 [0035] When a local area network established between the device or a certain service, a packet transmission service based on the service, as shown in the transmission of packet traffic, the distributed processing system of the distributed network 1 network devices are connected to the processing system or network, the network distributed processing system memory configuration information in the service business, comprising: receiving a service packet and transmitting traffic information service packet processing board passes, and port information of the port where LAG (link aggregation group, LAG) port information group, the MPLS bearer service (multi-protocol label switching, MPLS) tunnel information, the VSI service (virtual service instance, virtual service instance) information, service usage VLAN (virtual Local Area Network, VLAN) information, MAC address aging time business information. 该业务可以由VSI和VLAN来唯一确定。 The business can be uniquely determined by the VSI and VLAN. 其中,MPLS隧道信息包括工作Ingress (入方向)的MPLS隧道信息、工作Egress (出方向)的MPLS隧道信息、保护Ingress的MPLS隧道信息和保护Egress的MPLS隧道信息。 Wherein, MPLS tunnel information including work Ingress (inbound) an MPLS tunnel information, work Egress (outbound) information of the MPLS tunnel, MPLS tunnel information protection MPLS tunnel information of the Ingress and Egress protection. 该分布式网络处理系统中的相应业务配置信息也会存储在该系统内对应的业务处理板中。 Corresponding to the service configuration information is also stored in the distributed network processing system corresponding to the system in the service processing board.

[0036] 通过该分布式网络处理系统进行传输的该业务的业务报文中包含MAC地址和该业务使用的VLAN信息,其中MAC地址包括DA(DestinationAddress,目的地址)和SA(Source Address,源地址)。 Service packets [0036] for the service transmitted by the distributed network processing system comprises a MAC address and VLAN information used by the service, wherein the MAC address comprises a DA (DestinationAddress, destination address), and SA (Source Address, Source Address ). 当然,业务报文中也可以不包括VLAN信息。 Of course, the service packet may not include VLAN information.

[0037] 如图2所示,是本发明实施例分布式网络处理系统的MAC地址表项信息同步方法的流程图。 [0037] As shown in FIG 2 is a flowchart of MAC address entries distributed network synchronization method according to the embodiment of the processing system of the present invention. 该方法包括: The method comprising:

[0038] 步骤201,在同一业务的业务报文传输过程中,收到所述业务报文的业务处理板依据所述业务报文的MAC地址,学习或更新所述MAC地址对应的MAC地址表项信息,所述MAC地址表项信息为所述MAC地址与所述业务处理板端口的对应关系; [0038] Step 201, service packet transmission process in the same service, the service receives the service packet processing board based on the MAC address of the service packet, the learning or updating the MAC address corresponding to the MAC address table item information, the MAC address entry information of the MAC address and the corresponding relationship between port of service processing board;

[0039] 如图3所示,当某一业务处理板A从端口P0RT301接收一个业务报文时,该业务处理板A根据该业务报文的DA查找是否有对应的MAC地址表项信息,其中,MAC地址表项如图4所示,包括MAC地址表项信息及老化时间Aging Time,其中,MAC地址表项信息即MAC 地址与业务处理板号BID、端口号PID的对应关系。 [0039] As shown, when a certain service processing board A packet received from a service port P0RT301, the lookup service processing board A 3 of the DA service packet if the MAC address entries corresponding to, wherein , the MAC address table shown in Figure 4, includes a MAC address table and the time of aging aging time, which, i.e., MAC address entries corresponding relationship between the MAC address and the LPU BID number, the port number of the PID. MAC地址表项的老化时间,是当学习或更新该MAC地址表项信息时,根据业务配置信息中的设置或系统的默认值自动设定的。 Aging time of the MAC address entry is updated or when the learning of the MAC address entries, according to a default value set in the service configuration information of the system or automatically set.

[0040] 若找到MAC地址为DA的MAC地址表项信息,即可得知DA与出端口的对应关系,从而将该业务报文从该端口转发至目的地,该端口可能在本业务处理板A,也可能在另一业务处理板B。 [0040] If the found MAC address as the MAC address entries DA, the DA can know a correspondence relationship with the port to be forwarded to the service packet from the destination port, which may be present in the LPU A, it is also possible in another LPU B.

[0041] 假设该端口在业务处理板B的端口P0RT302,则业务处理板A将业务报文转发至业务处理板B,该转发过程也可以通过连接两业务处理板的交换板来完成。 [0041] Assume that the service processing ports in the port plate P0RT302 B, the service processing board A forwards the packet to the service processing service board B, the process can also be forwarded by connecting two LPU board to complete the exchange. 其中,不管业务报文是由业务处理板A直接转发给业务处理板B,还是业务处理板A通过交换板转发给业务处理板B,业务报文均通过板间业务处理通道进行转发。 Wherein, regardless of the service packet is forwarded by the LPU to LPU A B directly, or forwarded by the service processing board A plate exchanger plate B to the service processing, service packets are forwarded by the service processing channels between the plates.

[0042] 业务处理板B根据业务报文MAC地址SA,查找本业务处理板B内是否有SA对应的MAC地址表项信息,若有,则对该MAC地址表项信息进行更新,若无,则学习该MAC地址表项信息,所谓学习即建立SA与该业务报文的来源业务处理板号A及其端口号的对应信息, 该表项信息建立或刷新后会根据相应业务配置信息中的设置或系统默认一段时间值产生该表项的老化时间,该老化时间也可以根据需要进行修改或重新设定。 [0042] The service processing board B according to a service address SA MAC packet, the MAC address table to find out whether there are entries corresponding to SA in this LPU B, and if so, the MAC address entry information is updated, if not, after this the information of MAC address learning entry, i.e. a so-called learning SA established correspondence information sources LPU a number of the service and the port number of the packet, the entry information may establish or refreshed in accordance with the configuration information corresponding service setting a time value or a default aging time to the entry, the aging time can also be modified as required or reset. 当然对于SA对应的MAC地址表项信息的学习或更新也可以在业务处理板A中进行。 Of course, also possible to learn or to update the MAC address entries corresponding to SA in the panel A service processing. 假设该端口仍然在业务处理板A中,则上述过程直接在业务处理板A中完成。 Assuming that the port remains, the above process is completed in the service processing board A service processing directly in the panel A.

[0043] 可以在所述学习或更新所述MAC地址对应的MAC地址表项信息之前,判断所述业务报文是否来自分布式网络处理系统的板间业务处理通道,若是,则依据所述业务报文学习或更新所述MAC地址对应的MAC地址表项信息。 Service processing channels between the plates [0043] may be performed before the MAC address entries or updating the learned MAC address, it is determined whether the packet service from the distributed network processing systems, if yes, according to the service MAC address entries learned or updated message corresponding to the MAC address.

[0044] 业务报文有两种来源,如上述业务处理板A接收到的业务报文来源于分布式网络处理系统的外部设备或网络,而业务处理板B接收到的业务报文来源于该系统内的板间业务处理通道,本实施例中对业务报文的来源进行判断,在业务处理板B中进行MAC地址表项信息的学习或更新,这样业务处理板A只负责业务报文的转发,学习或更新MAC地址表项信息由业务处理板B完成,有利于提高业务报文的处理效率。 [0044] There are two sources of service packets, as described above LPU A service packet received from the external network device or network distributed processing system, and the service processing board B receives the packet service from the between the plates service processing channels within the system, the present embodiment of the service packet source judgment, learning the MAC address entries or updated in the service processing board B, so LPU a only responsible for service packets forward, to learn or update MAC address entries completed by the LPU B, it will help improve the efficiency of service packets.

[0045] 步骤202,在所述分布式网络处理系统的同一用户网络接口侧或同一网络网络接口侧,如果接收业务报文的传输端口与发送业务报文的传输端口不在同一业务处理板上, 则将所述MAC地址表项信息同步到所述分布式网络处理系统的其它业务处理板。 [0045] Step 202, the user network interface on the same side of the distributed processing network or system the same network interface to a network side, if the reception port the transmission port of the transmission service message service message transmission is not the same LPU, then the MAC address table items to be synchronized to other service processing board processing system of the distributed network.

[0046] 根据G. 8012/Y. 1308协议,分布式网络处理系统具有两种接口侧:UNI (User Network Interface,用户网络接口)侧禾口NNI (Network Network Interface,网络网络接口)侧,其中,UNI侧是用户设备与网络之间的接口,直接面向用户设备,使用户设备与网络之间或网络与用户设备之间能够相互交换信息;NNI可理解为网络节点接口或网络/网络之间的接口。 [0046] According to G. 8012 / Y 1308 protocol, a distributed processing system network side has two interfaces: UNI (User Network Interface, User Network Interface) port side Wo NNI (Network Network Interface, Network Network Interface) side, wherein , the UNI is an interface between the user-side equipment and the network, directly to the user equipment, cause the user equipment or the network between the user equipment and a network to exchange information; understood between the NNI network node Interface or network / networks interface. 例如,当分布式网络处理系统进行用户设备与运营商之间的业务报文传输时, 用户设备侧为UNI侧,运营商侧为NNI侧,当分布式网络处理系统进行两个用户设备之间的业务报文传输时,两个用户设备侧为两个不同的UNI侧;当分布式网络处理系统进行两个运营商之间的业务报文传输时,两个运营商侧为两个不同的NNI侧。 For example, when a distributed network processing system service message transmission between user equipment and the operators, the user equipment side as a side UNI, NNI side to the operator side, when the distributed network processing system between two user equipments when the packet transmission service, the user equipment two side UNI two different sides; when the traffic between the two systems distributed network processing packet transmission operator, two operators for the two different sides NNI side.

[0047] 在本发明实施例中,只要同一UNI侧或同一NNI侧,接收业务报文的传输端口与发送业务报文的传输端口不在同一业务处理板上,就将步骤201中学习或更新的MAC地址表项信息同步到其它业务处理板中。 [0047] In an embodiment of the present invention, one and the same side of the UNI or NNI same side, the transmission port of the transmission service message service message transmissions received are not the same port LPU, step 201 will be learned or updated synchronize MAC address entries to other service processing board.

[0048] 其中,在同一UNI侧或同一NNI侧,接收业务报文的传输端口与发送业务报文的传输端口是否在同一个业务处理板上,可以根据以下端口信息进行判断: Transmission port [0048] wherein, on the same side of the UNI or NNI same side, receiving service packet transmission port of the transmission service packets are in the same service processing board, may be determined according to the following port information:

[0049] LAG组端口是否在同一业务处理板上;或者,Egress的MPLS隧道端口与Ingress 的MPLS隧道端口是否在同一业务处理板上;或者,接收业务报文的工作Egress的MPLS隧道端口和保护Egress的MPLS隧道端口是否在同一业务处理板上;或者,发送业务报文的工作Ingress的MPLS隧道端口和保护Ingress的MPLS隧道端口是否在同一业务处理板上; 或者,上述判断的任意组合。 MPLS tunnel and a protection port or receive the service packet of the Egress Work; [0049] LAG port is set in the same LPU; or, Egress and Ingress port of the MPLS tunnel in MPLS tunnel port is in the same LPU Egress port is the MPLS tunnel traffic processing the same plate; or send traffic packets of MPLS tunnel work Ingress protection Ingress port and the port is the same MPLS tunnel in the LPU; or any combination of the above-described determination.

[0050] 也可以按照一定的顺序进行判断,在本实施例中,采用以下顺序进行判断: [0050] The determination may be performed in a certain order, in the present embodiment, the following sequence is determined:

[0055] 只要在同一UNI侧或同一NNI侧,接收业务报文的传输端口与发送业务报文的传输端口不在同一业务处理板上,即可将所述MAC地址表项信息同步到所述分布式网络处理系统的其它业务处理板,也可以对两侧都进行上述判断。 [0055] As long as the transfer port side of the same UNI or NNI same side, receiving service packet transmission port packet transmission service is not the same business processing board, to the MAC address entries to the synchronization profile other service processing board network processing systems, may be performed for both sides of the determination. 当业务配置信息中的MPLS隧道发生变化或LAG组创建删除时,可以重新执行上述判断步骤,可以按照Sl〜S4的判断步骤进行。 When MPLS tunnel service configuration information is changed or deleted to create the LAG, can re-execute the determination step, determination may be performed according to the steps Sl~S4.

[0056] 本发明实施例中,对MAC地址表项信息是否进行同步的情况进行了分析,在同一业务的业务报文传输过程中,同一UNI侧或同一NNI侧,接收业务报文的传输端口与发送业务报文的传输端口不在同一业务处理板上的条件下,进行MAC地址表项信息的同步,提高了MAC地址表项信息同步的效率,而且节省了业务处理板中MAC地址表项信息占用的空间。 [0056] The embodiments of the present invention, the MAC address table whether synchronization is analyzed, the service packet transmission process to the same service, the same UNI side or the same NNI side, the transmission port receives traffic packets under conditions of transmission service packet transmission port is not in the same business processing board, the MAC address table synchronization information to improve the efficiency of the MAC address entries synchronized, but also saves the MAC address entries LPU the space occupied. 具体将所述MAC地址表项信息同步到所述分布式网络处理系统的其它业务处理板的方法可以参照以下实施例。 Other methods LPU the specific MAC address entries to synchronize the distributed network of processing systems may reference to the following examples.

[0057] 参照图5,为本发明实施例将MAC地址表项信息同步至分布式网络处理系统的其他业务处理板的方法流程图。 [0057] Referring to Figure 5, a flowchart of the method of the present MAC address entries LPU other distributed network synchronized to the embodiment of the invention the processing system.

[0058] 本实施例中采用FDB2 (Filtering DataBase2,转发数据库)表来设置各业务处理板的同步信息,以控制MAC地址表项信息的同步,FDB2表的结构如图6所示,包括VSI、VLAN 和MAC同步比特位S,也可以再设置其它信息。 [0058] The present embodiment employed FDB2 (Filtering DataBase2, forwarding database) table to set the synchronization information of each service processing boards to control the synchronization of the MAC address entries, the table structure shown in FIG. 6 FDB2, including the VSI, VLAN and MAC synchronization bits S, other information may be further provided. 其中,FDB2表中的VLAN可以为非法值,即FDB2表中可以不包含VLAN信息。 Wherein, FDB2 VLAN table may be an illegal value, i.e. FDB2 table may not contain VLAN information. [0059] 在FDB2表中“MAC同步比特位S” 601,用来表示是否需要进行MAC地址表项信息的同步,若同步比特位设置为1,表示该MAC地址表项信息需要同步,同步比特位为“0”,表示可以不进行同步。 [0059] In Table FDB2 "MAC sync bits S" 601, is used to indicate the need for synchronization of the MAC address entries, if the synchronization bit is set to 1, indicating that the MAC address entry information needs to be synchronized, synchronization bits bit is "0", that can not be synchronized.

[0060] 在同一UNI侧或同一NNI侧,当接收业务报文的传输端口与发送业务报文的传输端口不在同一业务处理板上时,将该业务的业务配置信息中涉及到的各业务处理板中,与该业务的VLAN信息和VSI信息对应的FDB2表中的同步比特位设置为“1”,将该业务配置信息中未涉及到其它的业务处理板中,与该业务的VLAN信息和VSI信息对应的FDB2表中的同步比特位设置为“0”。 [0060] at the same side of the UNI or NNI same side, when the transfer port and the transmission port transmission service packet received service message is not the same business processing board, to the service configuration information of each service in the service processing plate, provided with the information and the sync bit VLAN FDB2 VSI information corresponding to the service table is "1", the service configuration information is not related to other service processing board, and the service VLAN information and synchronous bit information corresponding to the VSI FDB2 table is set to "0." 在UNI侧和NNI侧,当接收业务报文的传输端口与发送业务报文的传输端口均在同一业务处理板上时,可以将各业务处理板中,与该业务的VLAN信息和VSI信息对应的FDB2表中的同步比特位均设置为“0”。 NNI and the UNI side side, when receiving a service packet transmission port transmission port of the transmission service packets are processed at the same service panel, each LPU may be, the VSI corresponding to the VLAN information and information of the service FDB2 bit synchronization bits in the table are set to "0." 若FDB2表中的VLAN信息为非法值时,上述同步比特位的设置过程,可以只依据该业务的VSI信息进行。 If the VLAN information table FDB2 an illegal value, a bit of the synchronization setting procedure may be performed only on the basis of the service information VSI.

[0061] 在学习或更新MAC地址表项信息之后,可以直接参照FDB2表的信息,判断是否进行该MAC地址表项信息的同步,也可以省略或采取其它的方式对该分布式网络处理系统中的业务处理板的同步信息进行标记。 [0061] After the learned or updated MAC address entries, direct reference to the information table FDB2 determines whether synchronization of the MAC address entries may be omitted or take other embodiment of the distributed network processing system synchronization information LPU labeled. 如直接在业务处理板中查找是否有相应的业务配置信息,再判断是否进行相应MAC地址表项信息的同步。 The LPU look directly whether a corresponding service configuration information, and then determines whether the corresponding MAC address entry information of synchronization.

[0062] 在学习或更新MAC地址表项信息之后,如果业务报文中包含VLAN信息,则根据业务报文的VLAN信息以及该业务报文对应的业务配置信息中的VSI信息,查看具有相同VLAN 信息和VSI信息的FDB2表中的同步比特位,若同步比特位值为“1”则说明该学习或更新的MAC地址表项信息需要同步到该分布式网络处理系统的其它业务处理板,若为“0”则可以不用进行同步。 [0062] After the learned or updated MAC address table, if the traffic packet includes VLAN information, in accordance with VSI information service VLAN configuration information of the service packets and service packet corresponding view with the same VLAN FDB2 sync bit table information and information in the VSI, when the synchronization bit is "1" indicates that a MAC address learned or updated entries need to be synchronized to the LPU other distributed network processing systems, if "0" can not be synchronized. 如果业务报文中不包含VLAN信息,则根据业务报文查找对应的业务配置信息中的VSI信息,然后在与该VSI信息对应的FDB2表中,查看同步比特位值。 If no VLAN information packet service, the service packet according to the service configuration information to find the information corresponding to the VSI in, then FDB2 table corresponding to the VSI with the information of synchronous bit value.

[0063] 在本实施例中,若学习或更新MAC地址表项信息之后,查到的FDB2表中的同步比特位为“1”,则需要将所述MAC地址表项信息同步到所述分布式网络处理系统的其它业务处理板,可以包括以下步骤, [0063] In the present embodiment, after the updating or when the MAC address learning table entries, the synchronization bits found in the table FDB2 is "1", then the need to synchronize MAC address entries to the profile other service processing board network processing system may include the steps of,

[0064] 步骤501,构造同步报文,所述同步报文包含所述MAC地址表项信息和相关业务配 [0064] Step 501, the configuration of the synchronization packet, said synchronization packet comprises a MAC address entry with information and services related

直fe息。 Straight fe interest.

[0065] 依据相应MAC地址表项信息中的源地址SA、报文来源业务处理板号A及端口号等信息,构造同步报文,如图7所示,在本实施例中,该同步报文的固定长度为15个字节,仅仅包括VSI编号(16比特)、VLAN(12比特)、SA(48比特)、业务处理板号BID(16比特)、端口号PID(12比特)、CRC校验(16比特),该同步报文占用很少的流量,业务处理板号等还预留空间以向后扩展。 [0065] based on the source address SA corresponding MAC address entry information, source packet number A LPU and port number and other information, configuration synchronization packet, shown in Figure 7, in the present embodiment, the synchronization message fixed length packets of 15 bytes, comprises only VSI ID (16 bits), VLAN (12 bits), SA (48 bits), LPU BID number (16 bits), the port number PID (12 bits), CRC checksum (16 bits), the synchronizing packets occupy very little traffic, LPU with room number and the like to extend rearwardly. 当然,该同步报文中也可以不包括VLAN信息。 Of course, this synchronization message may not include VLAN information.

[0066] 还可以包括步骤502,为所述同步报文设定优先级,一般学习的MAC地址表项信息产生的同步报文设定为优先,更新的MAC地址表项信息产生的同步报文为次之;当有多个同步报文需要广播时,根据所述同步报文的优先级优先广播优先级高的同步报文。 [0066] Step 502 may further include setting priority of the synchronization packet, the MAC address learning general entries generated synchronization set as the priority packets, packet synchronization update MAC address entries generated It is second; when a plurality of synchronization packets need to broadcast broadcast priorities according to a priority of the synchronization packet a higher priority sync packet.

[0067] 对同步报文进行优先级的设置也是为了防止过量的同步报文的发送,而在发送时按优先级进行排队,先发送优先的同步报文。 [0067] The synchronization packet priority is provided to prevent excess transmit synchronization packets, and queue priority at the time of transmission, the first synchronization message transmission priority. 当然,也可以根据需要对优先级别进行重新设置。 Of course, you can also re-set the priority as needed.

[0068] 步骤503,通过板间通信通道广播所述同步报文至所述分布式网络处理系统的其它业务处理板。 [0068] Step 503, the synchronization message broadcast by the inter-board communication channel to the other distributed processing network service processing system board. [0069] 同步报文采用板间通信通道进行发送,而不占用业务处理通道,以不影响业务报文的传输。 [0069] The synchronization packet inter-board communication channel transmission using, without taking service processing channel, without affecting the service packet transmission. 一般采用广播的方式将同步报文发送至其他业务处理板中,其中所述广播的方式,具体可以是将同步报文先发送至该分布式网络处理系统主控板的Ianswitch模块(转发模块)中,然后在Lanswitch模块中对该同步报文进行复制,再由Lanswitch模块将复制的同步报文发送至分布式网络处理系统的其他业务处理板。 Generally through broadcast synchronization packet to the other service processing board, wherein the broadcast mode may be a particular synchronization packet to be sent to the distributed network processing module Ianswitch system MPU (forwarding module) then the sync packet replication Lanswitch module, then the module will be copied Lanswitch synchronization packet is sent to the other service processor cards distributed network processing system. 当然,也可以直接广播至其他业务处理板,也可以采用业务处理板间的单播方式来发送同步报文。 Of course, the other may be directly broadcast to the LPU may be between unicast service processing board to transmit synchronization messages.

[0070] 本实施例中,在同步报文流量大时,可以对同步报文进行流量限制,以防止同步报文流量过大而产生信息阻塞。 [0070] In this embodiment, when the synchronous packet is larger flow, the flow rate can limit synchronization packet, synchronization packet stream to prevent excessive clogging generated information. 同时,可以根据发送、接收同步报文以及通道的带宽整体情形来决定发送频率、接收频率和板间通信通道的带宽,避免某个环节有瓶颈或者某个环节资源浪费较多,本实施例MAC地址同步报文最大处理能力限制在每秒50K。 At the same time, can send, receive a synchronization packet and a bandwidth case where the entire channel to determine transmission frequency, reception frequency bandwidth between a communication channel and plate to avoid a bottleneck link or links of a large waste of resources, for example, MAC the present embodiment address synchronization packets maximum processing capacity is limited to 50K per second.

[0071] 本实施例还可以包括步骤504,所述分布式网络处理系统的其它业务处理板在收到同步报文后,如果同步报文中的相关业务配置信息与所述业务处理板的业务配置信息相匹配,则依据所述同步报文,学习或更新该MAC地址对应的MAC地址表项信息。 [0071] This embodiment may further include the step 504, the distributed network of processing systems other LPU after receiving the synchronization packet, if the synchronization packet service information associated with the service configuration LPU configuration information matches, then according to the synchronization packet, learned or updated MAC address entries corresponding to the MAC address.

[0072] 具体的,也可以按照以下顺序依次判断是否需要学习或更新MAC地址表项信息, 也可以进行其中部分判断: [0072] Specifically, the sequence may be determined whether to update the MAC address learning or entries in the following order, it can also be determined in part:

[0073] 首先,判断同步报文的VSI信息和VLAN信息与本业务处理板的相应信息是否匹配,当同步报文中不包含VLAN信息时,只判断同步报文的VSI信息与本业务处理板的相应信息是否匹配,若匹配,即本业务处理板中有该VSI的基于该VLAN的业务,则进行下一步判断;若不匹配则丢弃同步报文,不进行学习或更新。 [0073] First, the corresponding information VSI information and VLAN information of the present LPU determines synchronization message match, when the synchronization packet does not contain the VLAN information, only determines the VSI information present LPU synchronization packets the corresponding information match, if match, i.e., there is present in the service processing board based on the VLAN service, then the next step is determining the VSI; if not matching the synchronization packet is discarded, without learning or updating.

[0074] 然后,判断所述业务处理板的端口是否属于所述业务配置信息中涉及的传输端口,即查看本业务处理板中与同步报文中的VLAN信息和VSI信息相应的FDB2表,是否同步比特位置为“1”,若同步比特位为“1”,则进入下一步判断;若不匹配或同步比特位为“0 “, 则丢弃同步报文,不进行学习或更新;若同步报文中不包含VLAN信息或FDB2表中不包含VLAN信息时,只查看VSI信息即可。 [0074] Then, the port determines whether the LPU transmission port involved in the service configuration information, i.e., to view this information service processing board table and the respective synchronization message FDB2 the VLAN and the VSI information, whether sync bit position is "1", if the synchronization bit is "1", the process proceeds to the next determination; if a match or the synchronization bit is "0", the synchronization packet is discarded, without learning or updating; if synchronization message when the text does not contain VLAN information or FDB2 table does not include VLAN information, you can only view the VSI information.

[0075] 然后,判断同步报文中的业务处理板号是否为本业务处理板,若否,则依据同步报文,学习或更新所述MAC地址表项信息;若是,则丢弃同步报文,不进行学习或更新。 [0075] Then, in synchronization determination LPU whether the present packet LPU, if not, based on the synchronization packet, the MAC address learning or updating entries; if yes, discards the synchronization packet, not learn or update.

[0076] 依据同步报文学习或更新自己的MAC地址表项信息,具体的是指,依据同步报文中的MAC地址表项信息查找本业务处理板中是否有对应的MAC地址表项信息,若有则更新该MAC地址表项信息,若没有则学习该MAC地址表项信息。 [0076] According synchronization packet learning or update their MAC address entries, specifically it refers to, according to the MAC address table information synchronization packets to find whether there is a corresponding MAC address entries present service processing board, If the MAC address entries are updated, if not the MAC address entries are learning.

[0077] 通过该方法可以先判断是否需要对MAC地址表项信息进行学习或更新,减少了不必要的MAC地址表项信息的同步,节省了业务处理板中MAC地址表项信息的占用空间。 [0077] By this method may first determine whether the MAC address entry information learned or updated, the synchronization reduces unnecessary MAC address entries, saving space service processing board of the MAC address entries.

[0078] 以上实施例中,学习或更新MAC地址表项信息后会根据业务配置信息中的设置或系统默认一段时间作为该表项的老化时间,为了保证各业务处理板中的相应MAC地址表项信息的老化时间是同步的,各业务处理板的MAC地址表项信息的老化时间所用的是同一时钟基准,如系统的2K时钟。 After [0078] the above embodiment, the learning or updating MAC address entries based on service configuration information settings or system default period of time as the aging time of the entry, in order to ensure the corresponding MAC address of each service processing board aging time items of information are synchronized, the aging time of MAC address entries each LPU 2K used was the reference clocks of the same, as the system.
