Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of an overall structure of an embodiment of the present invention, and fig. 2 is a schematic diagram of a topology structure of interconnection between a server node 3 and a switch 4.
In a specific embodiment provided by the present invention, the node wireless interconnection system architecture mainly includes a plurality of server nodes 3 and switches 4, and a node wireless module 5 and a switching wireless module 6.
Wherein, each server node 3 and switch 4 all install in the cabinet body 1 to all install node wireless module 5 in every server node 3, mainly used passes through wireless communication mode receiving and dispatching data. The switch 4 is provided with a switching wireless module 6 for transmitting and receiving data mainly in a wireless communication manner.
Meanwhile, local area network interconnection is formed between the server nodes 3 through wireless communication between the node wireless modules 5, or local area network interconnection is formed through wireless communication between the node wireless modules 5 and the exchange wireless module 6, and the server nodes 3 can be in signal connection with external electronic equipment through wireless communication between the node wireless modules 5 and the exchange wireless module 6, so that the server nodes 3 in different server cabinets can be interconnected by using the data receiving and sending functions of the exchange wireless module 6.
So, the wireless interconnected system architecture of node that this embodiment provided, through the wireless communication between a plurality of node wireless module 5 and the exchange wireless module 6, can make each server node 3 in the whole rack form wireless interconnected local area network or form wireless interconnected local area network through switch 4, thereby can ensure the internal and external communication demand of server node 3, compared with prior art, the data cable that interconnection or external antithetical couplet between server node 3 need not to lay in the cabinet body 1, wiring space occupation has been reduced by a wide margin, the system architecture is simplified, more installation space in the cabinet body 1 has been released, be favorable to the extremely intensive design of heat dissipation and rack.
In a preferred embodiment regarding each of the server nodes 3, considering that the server nodes 3 have a generally flat rectangular shape, the server nodes 3 may be stacked in a vertical direction within the cabinet 1. So set up, each server node 3 can mainly occupy the vertical space in the cabinet body 1 to improve installation density.
As shown in fig. 3, fig. 3 is a schematic diagram of an internal structure of a server rack.
In a preferred embodiment of the switch 4, in order to avoid the switch 4 from occupying an extra node installation space, in this embodiment, the switch 4 is specifically installed in the wiring space at the front end and the rear end in the cabinet 1. So set up, because no longer lay the data cable that is used for server node 3 interconnection or external connection in the cabinet body 1, consequently walk the line space and vacate, can conveniently install switch 4. Meanwhile, the wiring space reserved at the front end and the rear end of the cabinet body 1 can be further opened to be a heat dissipation channel 2, or can be reused as an expansion space of the server case at the same time, so that the internal installation space of the server case is increased. For example, the server chassis under the new system architecture may increase in width from 447mm to 538mm and in depth from 950mm to 1050mm, as compared to a standard 19 inch chassis.
In order to ensure smooth communication and low delay among the wirelessly interconnected server nodes 3, in this embodiment, considering that the current 5G wireless communication rate can reach 1Gbps, can reach 10Gbps in the future, and can even reach a higher rate under the 6G wireless communication standard, the requirement of the internal communication rate of the whole cabinet can be met, and therefore, each node wireless module 5 and each switching wireless module 6 can be both 5G wireless communication modules. Of course, each of the node wireless modules 5 and the switching wireless module 6 may also adopt wireless communication modes such as WIFI and 4G.
The specific work flow of the node wireless interconnection system architecture comprises two types of data transmission links, namely, the server nodes 3 are interconnected internally, and the server nodes 3 are interconnected through exchange.
Wherein, the data transmission link one: the server nodes 3 are interconnected through a wireless network established by the node wireless module 5, and data transmission is carried out by a PCIE link. Specifically, signal connection is established with each node wireless module 5 through the broadcast module 7, then a data packet of any server node 3 is sent to the ports of all the other server nodes 3, then the ports of the other server nodes 3 feed back a feedback signal to the MAC obtaining module 8, the MAC obtaining module 8 analyzes the MAC address corresponding to the port of each server node 3, and sends the MAC address to the broadcast module 7, so that all the server nodes 3 know the MAC addresses of the other server nodes 3.
As shown in fig. 4, fig. 4 is a flowchart of the internal communication of the server node 3;
for example, the server node 3A sends data to the server node 3B, the a first checks whether the MAC address of the B exists in the address table, if the MAC address of the B exists, the data packet is directly sent to the corresponding port, if the MAC address of the B does not exist, the data packet is first broadcast to all the ports, the B responds to the MAC address of the B, and the a stores the MAC address of the B in the address directory table and sends the data packet to the corresponding port.
And a second data transmission link: the server nodes 3 establish wireless network interconnection through the exchange wireless module 6. Specifically, the address acquisition module 9 is in signal connection with each node wireless module 5, the switching wireless module 6 is used for acquiring the IP address of each server node 3, when each server node 3 is in the same network segment, the ARP request module 10 is used for enabling any server node 3 to send an ARP request to all other server nodes 3 through the switching wireless module 6, and finally all other server nodes 3 feed back a signal to the switching wireless module 6 according to the ARP request, and the MAC analysis module 11 analyzes the feedback signal, so that the MAC address corresponding to the port of each server node 3 is obtained. However, if the server nodes 3 are not in the same network segment, the first relay forwarding module 12 may first enable any server node 3 to send the data packet to the default gateway through the switching wireless module 6, and then forward the data packet to the port of the corresponding server node 3 through the switching wireless module 6 by the second relay forwarding module 13 according to the preset corresponding relationship between the MAC address of the default gateway and the MAC addresses of the remaining server nodes 3.
As shown in fig. 5, fig. 5 is a flowchart of the server node 3 communicating through the switch 4.
For example, server node 3A sends data to server node 3B through switching wireless module 6, and knowing the IP of B, a obtains the network address using the subnet mask, and determines whether the IP of B is in the same network segment as a. If the data packet is in the same network segment but the MAC address required by the forwarded data is not known, an ARP request is sent by the A, the MAC address is returned by the B, the A encapsulates the data packet by the MAC and sends the data packet to the switching wireless module 6, the switch 4 plays the role of a two-layer switching module, and then the MAC address table can be searched, and the data packet is forwarded to the corresponding port. If the IP address of B is not in the same network segment as A, A sends the first normal data packet to a default gateway, the default gateway is generally set in the operating system, and the IP of the default gateway corresponds to the third layer routing module, so for the data not in the same subnet, the MAC address of the default gateway is firstly put in the MAC table (completed by the source server node 3A); then the default gateway (third layer route module) receives the data packet, then queries the route table to determine the route to B, and constructs a new frame header, wherein the MAC address of the default gateway is used as the source MAC address, the MAC address of B is used as the destination MAC address, the corresponding relation between the MAC addresses of A and B and the forwarding port is established through the preset identification triggering mechanism, and the entry table of the flow cache is recorded, so that the data from A to B can be directly delivered to the switch 4 (second layer switching module).
The embodiment also provides a server cabinet, which mainly includes a cabinet body 1 and a node wireless interconnection system architecture arranged in the cabinet body 1, wherein specific contents of the node wireless interconnection system architecture are the same as those described above, and are not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
