Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
The flow chart that Fig. 1 is network element device loading method embodiment mono-of the present invention, as shown in Figure 1, the method for the present embodiment comprises:
When network element device is reached the standard grade access network, need the managing I P of configuration device and the Routing Protocol of each interface.Because each network element device comprises a plurality of interfaces, each interface may access different networks, move different Routing Protocols, therefore when a network element device is reached the standard grade, software debugging personnel's configuration effort amount will be very large, for reducing the configuration effort amount, in the present invention, by set up the interface of network element device and the corresponding relation of routed domain on Dynamic Host Configuration Protocol server or webmaster or controller, when network element device is reached the standard grade, can automatically interface be divided into to corresponding routed domain according to the corresponding relation obtained from server or webmaster or controller, thereby automatically start the Routing Protocol corresponding with this routed domain, realize planning-free when network element device is reached the standard grade and exempted from configuration.
The P2P Ethernet interface of step 102, described network element device utilizes described managing I P bearer management message.
Traditional Ethernet is broadcast type, total interface on Ethernet need to be at the same network segment, equipment is at broadcast transmission address resolution protocol (Address Resolution Protocol, be called for short ARP) during message, can be checked destination address, destination address and this interface IP address need to be at network segments.And point-to-point (peer to peer, abbreviation P2P) the IP address, two ends of Ethernet can be at a network segment, therefore, the P2P Ethernet interface is when ARP request and arp reply, do not check that whether the IP address is at the same network segment, thereby when network element device dispatches from the factory or equipment install while reaching the standard grade at least one interface configuration of equipment become to the P2P Ethernet interface, and utilize the administrative message of this P2P Ethernet interface transceiver, during due to P2P style interface transmitting-receiving message, the IP address is not limited, the managing I P of this P2P Ethernet interface can be the IP that automatically generates or by the IP of Dynamic Host Configuration Protocol server dynamic assignment, without configuring and will send to the managing I P of corresponding network element device and the corresponding relation of network element device position on server in advance, thereby the managing I P that has realized network element device exempts from configuration, reduced as the operation of network element device interface assignment IP address human configuration.
In mobile retransmission network (IP RAN), to return interface (Loopback interface) be the interface in active state always in this locality of network element device, therefore, in practical application, be using a P2P Ethernet interface as the Loopback interface, and the managing I P transmitting-receiving administrative message that this interface utilization is obtained.
In actual applications, the P2P Ethernet interface of network element device can configure when equipment dispatches from the factory, when equipment is installed while reaching the standard grade, the IP that the P2P Ethernet interface of configuration can utilize equipment automatically to generate or carry out the transmitting-receiving of administrative message as managing I P by the IP of Dynamic Host Configuration Protocol server dynamic assignment; The P2P Ethernet interface of network element device also can be configured when equipment is reached the standard grade, be before the managing I P bearer management message that receives while reaching the standard grade of the P2P Ethernet interface utilization of network element device, the interface configuration information that it is the P2P Ethernet interface that network element device obtains at least one interface configuration; And by least one interface configuration of described network element device, be the P2P Ethernet interface according to the interface configuration information of obtaining, when thereby the equipment of assurance is reached the standard grade by the IP address configuration obtained on this P2P Ethernet interface so that the transmitting-receiving administrative message, guarantee that the administrative message between network element device and server can normally receive and dispatch, the normal operation of maintenance network element device.
In the mobile retransmission network, the planning of network element address and configuration have accounted for the reach the standard grade major part of cost of network element.The all nodes of traditional Ethernet must can not be used IP at the same network segment, because the IP used is 32 bitmasks, at the different network segments.For realizing using of IP, method based on the P2P Ethernet in the embodiment of the present invention, at least one interface configuration that is about to network element device becomes the P2P Ethernet interface, due to the P2P Ethernet interface without requiring the address, two ends at the same network segment, make the P2P Ethernet interface can use managing I P, thereby avoided the artificial planning and configuration of a large amount of interface IP addresses.
In the present embodiment, when network element device is reached the standard grade, not only realized manpower-free's configuration of managing I P, and network element device also starts Routing Protocol automatically according to the interface of its reception and the corresponding relation of routed domain, only need the routed domain division of each interface of configuration network element device to get final product, and without writing configuration script for each interface in order to start the interface route agreement, reduced the configuration effort to each interface, specifically, because routed domain is corresponding with corresponding Routing Protocol, when interface is divided into a routed domain, the corresponding Routing Protocol according to this routed domain, the interface automatically starting Routing Protocol of network element device, thereby reduced the human configuration work of each interface route agreement.
The normal operation of the managing I P bearer management message maintenance network element device that the embodiment of the present invention is obtained by the P2P Ethernet interface utilization of network element device, because the IP address at P2P Ethernet interface two ends can be at a network segment, therefore this managing I P can automatically be generated or be participated in configuration by the IP of Dynamic Host Configuration Protocol server dynamic assignment without artificial by equipment, thereby has reduced as the operation of network element device interface assignment IP address human configuration; Simultaneously, the interface that network element device obtains by basis and the corresponding relation of routed domain are at described interfaces enabled and Routing Protocol that described routed domain is corresponding, make the Routing Protocol configuration of each interface also be simplified, thereby reduced the Routing Protocol configuration effort of each interface of network element device.
The flow chart that Fig. 2 is network element device loading method embodiment bis-of the present invention, Fig. 3 is application scenarios schematic diagram embodiment illustrated in fig. 2, Fig. 4 is signaling diagram embodiment illustrated in fig. 2, in application scenarios as shown in Figure 3, base station and Service GateWay (Service Gateway is called for short SWG)/data gateway (Packet Data Network Gateway, abbreviation PGW) formed wireless network, network element device NE1 has formed the mobile retransmission network to NE5, and the mobile retransmission network provides service bearer for wireless network.Be that communicating by letter of base station and SGW/PGW passed through the mobile retransmission network carrying.In the LTE epoch, the mobile retransmission network provides the L3VPN business usually, and base station and SWG/PGW's communicates by letter by L3VPN or L2VPN carrying.Based on IP, provide the mobile retransmission network of L3VPN or L2VPN also referred to as IP RAN.In Fig. 3, five network element devices that NE1 is IP RAN to NE5.
In order to improve reliability, the common makeup ring l network of IP RAN network.In the present embodiment, network element device NE1 and NE2 have formed and have converged ring, network element device NE2, NE3, NE4, NE5 has formed access ring, each converges the lower accessible a plurality of access rings of ring, each converges network element number on ring and access ring usually individual even more than 20 more than ten, the so-called wireless traffic side of the network element be connected with SGW/PGW gateway (Radio Service Gateway, be called for short RSG), the so-called base station side gateway of the network element be connected with base station (Cell Site Gateway, be called for short CSG), the network element of bearing convergence service is called and converges side gateway (Aggregation Site Gateway, be called for short ASG).Application scenarios based on shown in Fig. 3, the network element device in the present embodiment can be NE1, NE2, NE3, NE4 or NE5, the method for the present embodiment comprises:
As shown in Figure 3 and Figure 4, when network element device NE1 reaches the standard grade, can automatically at total interface, send DHCP and find (DHCP Discover) message request managing I P, Dynamic Host Configuration Protocol server on same Ethernet (DHCP Server) response DHCP Discover message request, for network element device NE1 allocation manager IP, carry the managing I P of distribution in response message, carry the corresponding relation of each interface of network element device NE1 and routed domain simultaneously in response message, when thereby follow-up network element device is reached the standard grade, each interface can utilize this corresponding relation to carry out the Routing Protocol self-starting.
In the present embodiment, the corresponding relation of interface and routed domain can be interface and open type shortest path priority protocol (the Open Shortest Path First of the network element device in the option Option that is carried at the DHCP response message, the corresponding relation of zone (Area) sign abbreviation OSPF), the interface of network element device and Intermediate System-to-Intermediate System (Intermediate system to intermediatesystem, the corresponding relation of classification (Level) sign abbreviation IS-IS), perhaps network element role and the interface message of network element device, as the network element role is ASG role, and carry converge ring interface.
At present, the planning of Routing Protocol and configuration effort amount are mainly in the division of routed domain, and, owing in the IPRAN scene, mostly being low side devices, cpu performance is lower, if the network element number in each routed domain is too many, when routing update, the utilance of CPU can be too high, therefore, usually at the ASG node, routed domain scratched, being about to converge ring, to incorporate into be a routed domain, and it is an independent routed domain that each access ring incorporates into.In the embodiment of the present invention, routed domain is divided in DHCP Server and completes, and by DHCP Server, ready-portioned routed domain is carried in the dhcp response message and feeds back to network element device.Therefore, when network element device is the network element converged in the mobile retransmission network in ring or access ring, before network element device obtains the DHCP response message that Dynamic Host Configuration Protocol server returns, also comprise that DHCP Server carries out the routed domain distribution to the interface of network element device, be Dynamic Host Configuration Protocol server according to the network planning, will belong to converge the network element device in ring interface configuration in same routed domain, will belong to the interface configuration of the network element device in same access ring in same routed domain.
The P2P Ethernet interface of step 203, described network element device utilizes described managing I P bearer management message.
In this step, the managing I P that the interface that is configured to the P2P Ethernet interface on network element device can utilize DHCPServer to respond and return receives and dispatches administrative message as the IP address, to maintain the normal operation of network element device.
The syndeton schematic diagram that Fig. 5 is two network element devices in Fig. 3, as shown in Figure 3 and Figure 5, network element device NE1 and NE2 are two network elements in the mobile retransmission network, and the managing I P that NE1 obtains is 10.1.1.1, and the managing I P that NE2 obtains is 11.1.1.1.The interface g1/0/0 of NE1 is the P2P Ethernet interface, managing I P10.1.1.1 is used in address, the interface g1/0/0 of NE2 is also the P2P Ethernet interface, managing I P11.1.1.1 is used in address, owing to address not being checked when ARP request and the arp reply, therefore, the interface g1/0/0 address of NE1 and the interface g1/0/0 address of NE2 can not intercom at a network segment mutually, and the interface g1/0/0 of the interface g1/0/0 of NE1 and NE2 can communicate by letter mutually.
The routed domain that step 205, described network element device are divided according to interface is enabled the Routing Protocol corresponding with the place routed domain on corresponding interface.
After network element device receives the corresponding relation of interface and routed domain, at first network element device carries out the routed domain division to each interface of network element device, and network element device automatically starts the Routing Protocol corresponding with the routed domain of this interface on each interface afterwards.
The DHCP that step 207, described network element device send other network element devices finds that message relay is to described Dynamic Host Configuration Protocol server.
For the network element device indirectly connected with DHCP Server also can be communicated with DHCP Server, after reaching the standard grade with the direct-connected network element device of DHCP Server or indirectly connected network element device, can on the network element device of reaching the standard grade, start DHCP Relay function, and the address that is DHCP Server by the destination address of relaying, thereby when reaching the standard grade with the indirectly connected network element device of DHCP Server, the network element device of having reached the standard grade can be relayed to DHCP Server by the DHCP Discover of indirectly connected network element device, with the automatic acquisition managing I P that realizes each network element device in network and the corresponding relation of interface and routed domain.
In practical application, when network element device NE1 is first network element device of reaching the standard grade, as network element device NE1 and DHCP Server when direct-connected, network element device NE1 can directly communicate with DHCP Server after starting, and obtains the corresponding relation of managing I P and interface and routed domain; As network element device NE1 and DHCP Server when indirectly connected, can adopt manual reaching the standard grade, be the software debugging personnel reach the spot configuration management IP, start DHCP Relay and Routing Protocol, the dhcp relay feature that the DHCP Discover message of follow-up other network element devices can start by network element device NE1 is relayed to DHCP Server, so that DHCP Server is its allocation manager IP and routed domain, divides.While reaching the standard grade as network element device NE2, the DHCP Discover message relay that network element device NE1 can send network element device NE2 is to DHCPServer, DHCP Server distributes DHCP Server managing I P and routed domain to network element device NE2 are transmitted to network element device NE2, thereby the P2P Ethernet interface of network element device NE2 utilizes managing I P to manage the transmitting-receiving of message automatically, simultaneously, start Routing Protocol and dhcp relay feature according to the corresponding relation of the interface be assigned with and routed domain on each interface.
It is network element device allocation manager IP that the embodiment of the present invention dynamically generates IP by Dynamic Host Configuration Protocol server, the P2P Ethernet interface of network element device can be used the transmitting-receiving that this managing I P carries out administrative message, both guaranteed the maintenance of the normal operation of network element device, reduced again as the human configuration workload of network element device allocation manager IP; Simultaneously, carry the corresponding relation of interface and routed domain in the DHCP Option of the response message fed back at Dynamic Host Configuration Protocol server, while having guaranteed that network element device is reached the standard grade, can be according to from this interface and routed domain corresponding relation, automatically starting Routing Protocol, thereby simplified the configuration of the Routing Protocol of interface, reduced the configuration effort amount of routed domain.
