Description

Network element installation method, network element, DHCP server and network system

The present invention relates to the field of communications, and in particular, to a method for installing a network element, a network element, a DHCP server, and a network system. Background technique

The installation of the network element is a very expensive part of the network construction process. In addition to the completion of the network element cabling by the hardware personnel, the software personnel complete the initial configuration of the network element. The initial configuration of the network element is complicated. At present, operators have requested that the network element installation can achieve one inbound completion. One pit stop means that the installation of the network element can be completed by an engineering personnel once at the site. Therefore, how to implement automatic configuration and installation of network elements becomes the key to a one-stop installation.

At present, the automatic configuration scheme adopted by the industry mostly uses the Dynamic Host Configuration Protocol (DHCP) for interaction, and uses the serial number SN/KEY for authentication. The network element sends a DHCP client request (DHCP client request) to the DHCP server through the service interface to request the initial configuration. Here, the DHCP server is a logical concept. It can be integrated on other network elements, such as the gateway network element. Is a separate server. The DHCP client request may use the SN of the NE as the unique identifier, or may use the KEY input by the engineering personnel as the unique identifier, and transmit it through the Option field in the DHCP Protocol Data Unit (DHCP PDU). After receiving the DHCP client request, the DHCP server authenticates the SN/KEY in the request. If the authentication succeeds, it returns a DHCP server response packet (DHCP sever response packet) to the network element.

At present, the network structure of operators is diverse, and it is required to support some network elements to access through third-party networks and to perform unified management. Accessing through a third-party network is a concept that is independent of the self-organizing network. The self-organizing network means that all network elements, including the network element to be installed, the gateway network element, and the DHCP server, are all inside a carrier network and are connected through a third-party network. When the network element to be installed is connected to the gateway network element of a certain carrier network, the network needs to pass through the network of other carriers. The DHCP server also Located in this other carrier network. However, whether it is an ad hoc network or a third-party network, it can be a Layer 2 network, that is, packets are forwarded at Layer 2 or Layer 3 networks, that is, packets are forwarded at Layer 3.

In the course of research and practice of the prior art, the inventors of the present invention found that the prior art has the following problems:

In the scenario where a third-party network exists, because the Option field is user-defined, there is no public organization that guarantees the uniqueness of its value. Therefore, in the case of a third-party network, it may be associated with other network elements. conflict. In addition, the above solution requires the network element to store an SN number that identifies itself, or requires the engineer to input a KEY value on site, which increases the manufacturing cost and installation cost of the network element. Summary of the invention

One inbound network element installation in a three-party network scenario.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. Embodiment 1

FIG. 1 is a schematic flowchart of a method according to an embodiment of the present invention. The method includes: 101: Sending a DHCP client request packet to a DHCP server, where the DHCP client request packet carries the network management of the network element to be installed. Interface hardware address;

After the NE is started, you can select any available service interface to send DHCP client request packets to obtain configuration information. The packet is a broadcast packet. After the DHCP relay agent receives the broadcast packet, the DHCP relay agent receives the broadcast packet. The broadcast packet is converted into a unicast packet and sent to the DHCP server (DHCP sever).

Figure 2 shows the packet encapsulation format of a DHCP client requesting configuration information. The destination address of the link layer protocol is filled with the broadcast MAC address, and the source address SMAC is filled with the MAC address of the service interface for sending packets. The format of the DHCP PDU is shown in Figure 3. The "Chaddr" field in the DHCP PDU is the client. The hardware address (client hardware address) field is filled in with the hardware address of the network management interface of the network element to be installed.

As shown in FIG. 4, the schematic diagram of the network element to be installed includes a network management interface 41 and n service interfaces 42, a service module 43, and a management module 44. The service module 43 performs the processing of the service through the service interface 42. Ideally, the network management system directly connects to the network element through the network management interface for management, that is, the management module 44 and the network management interface 41 are connected. However, since most of the network elements to be installed are geographically dispersed, the network element is generally managed by transmitting the management message through the service interface 42, that is, the management module 44 and the service interface 42 are connected. In the embodiment of the present invention, the hardware address of the network management interface is filled in the "Chaddr" field, and the hardware address of the network management interface may be a network management interface MAC address or other hardware address, which is not limited by the present invention. Since hardware address allocation is globally unique, it is guaranteed that it will not conflict with other addresses. When the management module 44 of the network element shown in FIG. 4 sends a DHCP client request through any service interface 42, the "Chaddr" field in the DHCP PDU fills in the MAC address "MAC0" of the network management interface 41. Moreover, the DHCP server and the network management only need to store a network management interface hardware address, and do not need to store each service interface.

The MAC address also reduces the workload of the authentication comparison. The number of service interfaces of a network element to be installed. When the amount is large, the beneficial effect is more significant, and the engineering personnel can insert the communication line carrying the management information into any service interface when installing, which also improves the flexibility of the engineering installation.

The NE is authenticated. After the authentication is passed, the DHCP server response packet is sent to the NE to be installed. The DHCP server response packet carries the DCN (Data Communication Network) configuration information and the gateway NE corresponding to the NE to be installed. IP address, etc. If the NE to be installed is connected to the gateway NE through a third-party network, the DHCP server response packet carries the configuration information required for the NE to be installed through the third-party network. If the NE, DHCP server, and NE NE are to be connected to the gateway NE through a Layer 3 third-party network, that is, the packet is forwarded through Layer 3, the DHCP server responds. The packet carries the IP address of the service interface of the NE to be installed. The DHCP server response message has the same format as the DHCP client request message, and the information to be returned can be carried in the Options field of the DHCP PDU, which is not limited in this embodiment of the present invention.

The DHCP relay agent encapsulates the link layer destination address DMAC of the DHCP server response message according to the content of the client hardware address Chaddr field of the DHCP PDU, and fills in the link layer destination address DMAC of the DHCP server response message as the to-be-installed network. The network management interface hardware address of the element.
