Method for Obtaining Remote Network Address and Its Network Protocol System

technical field

The invention relates to a method for obtaining a remote network address, in particular to a method for obtaining a remote network address and its network protocol system in the case of a dynamic host setting protocol service.

Background technique

With the rapid development of information technology, the electronicization of enterprises has become a trend, so that ordinary personal computers can no longer meet the needs of enterprises in the market. Therefore, servers with high computing functions are born to meet the electronic needs of various enterprises today. And, with the needs of the market, a single server has gradually developed into a large-scale server system with multiple single servers. And the host of each single server will be placed in a rack (Rack) system, and will be managed uniformly by the system management terminal through the rack management controller in the rack system.

Generally speaking, the host computer of each server in each cabinet system is installed with a BIOS-executable boot program and an operating system (OperationSystem, OS), and this operating system will provide a Dynamic Host Configuration Protocol (DynamicHostConfigurationProtocol, DHCP) Serves the cabinet system. Moreover, the dynamic host setting protocol service can provide a network address (IP address) to each server in all cabinet systems. In this way, the server can communicate with a remote network.

However, when the dynamic host setting protocol service is closed, or when the dynamic host setting protocol service or the IP sharer fails, or when the dynamic host setting protocol service or the IP sharer is connected to the external entity area network (LocalAreaNetwork, When the LAN) is disconnected or fails, the server will also lose the ability to communicate externally through the LAN.

The system management terminal 11 is connected to the switch 12, and the switch 12 is connected to the container management controller 13 and each cabinet system.

The system management terminal 11 is used to provide a dynamic host setting protocol service through the switch 12 to manage a remote network (External LAN) and assign different temporary addresses to different devices or systems. The switch 12 provides multiple connection ports (not shown) to connect multiple cabinet systems, and the central processing unit (not shown) inside the switch 12 will pass an address resolution protocol (ADRP) when each port is successfully connected. AddressResolutionProtocol (ARP) obtains a media access control address (MediaAccessControlAddress, MACaddress) of each device or system that is successfully connected, and saves it as a switching table. The container management controller 13 can be installed in a container server to manage the operation of physical storage or cloud storage (cloudstorage) through the switch 12 .

Each cabinet system has its own internal network (LocalLAN). In one embodiment, the rack system 15 includes a rack management controller (Rack Management Controller, RMC) 14, multiple power distribution units (PowerDistributionUnit, PDU) 151, a switch 152, and multiple node servers (NodeServer).

The rack management controller 14 is connected to each power distributor 151 . In one embodiment, a power distributor 151 may be connected to a plurality of node servers 153 and a node server 154 through an Inter Integrated Circuit (I2C) bus.

Each node server (including a plurality of node servers 153 and node servers 154) in the power distributor 151 can be connected to each other in series or in parallel, and the node servers 154 and each node server 153 are connected to the switch respectively 152.

Under the normal operation of the dynamic host setting protocol service, the node server 154 in the cabinet system 15 obtains a remote network address (External IP Address) through the switch 152, and uses it to manage the network connection status of each node server 153 in the cabinet system 15. Therefore, the rack management controller 14 can be disposed in a computer host, but is not limited thereto.

The aforementioned node servers each represent a client computer, and each node server includes a baseboard management controller (not shown). In one embodiment, each node server can communicate with the corresponding power distributor 151 and switch 152 through each corresponding baseboard controller. In one embodiment, through the switch 152, the node server 154 executes the dynamic host setting protocol service.

First, when the network protocol system 10 starts (each starts the firmware of the rack management controller 14, the firmware of each power distributor 151 and the firmware of each node server), the network protocol system 10 will perform initialization actions, such as steps S210.

The rack system 15 will attempt to configure an internal network protocol of an rack management controller 14 to obtain an internal network address, and attempt to configure an internal network protocol of each power distributor 151 to obtain an internal network address so that Each power distributor 151 can communicate with the RMC 14, as in step S220.

In order to enable the rack system 15 to communicate with a remote network, the rack management controller 14 will detect the status of a remote network protocol to ensure whether the connection with the remote network is normal, as in step S230.

The rack management controller 14 determines whether to obtain a remote network address according to the detection of the state of the remote network protocol, as in step S240. When the RMC 14 detects that the remote network address has been obtained, it means that the dynamic host setting protocol service is operating normally.

When the rack management controller 14 detects that the remote network address has not been obtained, it means that the dynamic host setting protocol service fails, or the communication between the node server 154 and the switch 152 fails, so it is impossible to contact the remote network. As shown in Figure 1B. At this time, the rack management controller 14 will further detect a jumper disposed on the rack management controller 14 to obtain an identification code (Identification Code, ID) of itself, as in step S250.

Then, the rack management controller 14 further obtains a temporary address as the remote network address according to the obtained identification code and a first form. Wherein, the first form is used as a means of indexing the temporary address of the rack management controller 14 and is pre-stored in the rack management controller 14 . In an embodiment, the first form can design a corresponding temporary address according to the correspondence between an identification code and a jumper parameter, as shown in Table 1 below.

Table I

At the same time, the rack management controller 14 also sequentially transmits a first command package (command package) in the format of Intelligent Platform Management Interface (IPMI) or other formats to the corresponding power distribution through the internal network according to a second form. device 151, as in step S260. In one embodiment, the second table provides the relationship between each power distributor 151 and its corresponding temporary address group, and is pre-stored in the rack management controller 14, as shown in Table 2 below. The first command packet includes a corresponding temporary address group, and the temporary address group includes temporary addresses of multiple node servers, as shown in Table 2.

Power distributor serial number temporary address group 1 10.10.X.10～10.10.X.24 2 10.10.X.30～10.10.X.44 3 10.10.X.50～10.10.X.64 4 10.10.X.70～10.10.X.84 5 10.10.X.90～10.10.X.104

Table II

When the above-mentioned corresponding power distribution device 151 receives the first command packet, it means that the network protocol system 10 lacks the sharing mechanism of DHCP/IP, so the power distribution device 151 will start a network protocol distribution service (IPassignservice), so that each node The servers all obtain a temporary address (remote network address) to be able to communicate with the remote network, as in step S270.

Please refer to FIG. 1B and FIG. 3 at the same time. FIG. 3 is a flowchart of a network protocol distribution service executed by the network protocol system according to the present invention.

Taking a power distribution device 151 as an example, first, the power distribution device 151 sends corresponding IPMI format or other format query commands to the baseboard management controller of each node server in order to confirm the remote location of each node server. Peer network protocol status, and obtain a media access control address of the inquired node server, as in step S310.

According to the status of the remote network protocol of each node, it is judged whether each node has obtained a remote network address, such as step S320. When the inquired node has acquired the remote network address, go directly to step S360 to determine whether each node has been inquired. When there are still nodes that have not been queried, go back to step S310.

When there is a node server that has not obtained a temporary address, the power distributor 151 will send a second command packet in an IPMI format or other formats that includes a temporary address according to a second form, requesting a corresponding node server. The baseboard management controller is set to the temporary address, as in step S330.

When the corresponding node server receives the second command packet, it sets the temporary address according to the second command packet, and returns the corresponding MAC address to the power distributor 151, as in step S340. After receiving the MAC address, the power distributor 151 creates a third table according to the MAC address and the second table, as in step S350. In an embodiment, the third table provides a correspondence between a MAC address and a second temporary address of each node server.

In step S360, when there is still a node server that has not been queried, go back to step S310. When all the node servers have been inquired, the power distributor 151 returns the third form to the rack management controller 14, and the rack management controller 14 can know that each node server has completed the setting of the temporary address, as in the steps S370.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should all belong to the protection scope of the appended claims of the present invention.
