Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 illustrates an exemplary system architecture 100 of a method for communicating information or an apparatus for communicating information to which embodiments of the present disclosure may be applied.
As shown in fig. 1, system architecture 100 may include a head node N.0, intermediate nodes n.1, n.2, N.3, and a tail node N.4. Head node N.0, intermediate nodes n.1, n.2, N.3, and tail node N.4 may form a VXLAN tunnel (also called a VXLAN message transmission path).
It should be noted that the method for transferring information provided by the embodiments of the present disclosure is generally performed by the head node N.0, and accordingly, the apparatus for transferring information is generally disposed in the head node N.0.
The head node N.0 may be hardware or software. When head node N.0 is hardware, it may be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When the head node N.0 is software, it may be implemented as multiple software or software modules (e.g., for providing distributed services) or as a single software or software module, and is not limited in this respect.
It should be understood that the number of head, intermediate, and tail nodes in FIG. 1 is merely illustrative. There may be any number of head nodes, intermediate nodes, and tail nodes, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for communicating information in accordance with the present disclosure is shown. The method for communicating information includes the steps of:
In this embodiment, the execution subject of the method for transferring information (e.g., the head node N.0 shown in fig. 1) may receive the vlan message through a wired connection or a wireless connection. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
The virtual extended local area network message comprises outer layer message forwarding equipment address information and inner layer message receiving equipment address information. The message forwarding equipment address information is the address information of equipment at the tail end of a tunnel for forwarding the virtual extensible local area network message. The message receiving equipment address information is the address information of the terminal equipment to which the virtual extended local area network message needs to arrive. For example, terminal a needs to send a virtual extended lan packet to terminal B through a VXLAN tunnel formed by a plurality of nodes. Each node in the VXLAN tunnel needs to have a capability of parsing a virtual extended local area network message, so that the message receiving device address information is parsed from the virtual extended local area network message, and then the virtual extended local area network message is sent to a next node. And the next node analyzes the address information of the message receiving equipment from the virtual extended local area network message again and then sends the virtual extended local area network message to the next node. Therefore, each node carries out a large amount of repeated calculation, the requirement on the calculation capacity of the node is high, and meanwhile, a large amount of calculation resources are wasted.
Therefore, after receiving a virtual extended local area network message, an execution main body of the application firstly analyzes the message receiving equipment address information of the inner layer of the virtual extended local area network message and the message forwarding equipment address information of the outer layer of the virtual extended local area network message from the message. Namely, the execution main body of the application has the analysis capability on the virtual extensible local area network message. The message receiving device address information may include information such as an MAC address and an IP address of the message receiving device. The message forwarding device address information may include information such as an MAC address and an IP address of the message forwarding device. For example, terminal a sends a virtual extended lan message to terminal B through the VXLAN tunnel. The VXLAN tunnel includes a head node (i.e., the first node of the VXLAN tunnel), a number of intermediate nodes, and a tail node (i.e., the last node of the VXLAN tunnel). The message receiving device address information includes the MAC address and IP address of terminal a, the MAC address and IP address of terminal B, and so on; the message forwarding equipment address information comprises the MAC address and the IP address of the head node and the MAC address and the IP address of the tail node.
The execution body can process the address information of the message receiving device and calculate the address information of the message receiving device into a hash factor so as to simplify the address information of the message receiving device into digital information.
And 203, writing the hash factor into the virtual expansion local area network message to obtain an updated virtual expansion local area network message.
The virtual extended local area network message contains the residual data space. The execution main body can write the hash factor into the virtual expansion local area network message to obtain an updated virtual expansion local area network message. Therefore, the intermediate node does not need to analyze and calculate the address information of the message receiving equipment again. Only the hash factor needs to be parsed. Therefore, the computing power of the intermediate node is saved, and the performance requirement on the intermediate node is reduced. Meanwhile, the method is favorable for accelerating the transmission speed of the message in the VXLAN tunnel.
After obtaining the updated virtual extended local area network message, the execution main body may select a transmission path between the current node and the next node according to the address information of the message forwarding device, and send the updated virtual extended local area network message to the next node through the transmission path. Therefore, the updated virtual extensible local area network message is transmitted in the VXLAN tunnel. Because the updated virtual expanded local area network message contains the hash factor, other nodes can directly determine the address information of the message receiving equipment through the hash factor, and the updated virtual expanded local area network message does not need to be analyzed. Therefore, the computing power of the intermediate node is saved, and the performance requirement on the intermediate node is reduced. Meanwhile, the method is favorable for accelerating the transmission speed of the message in the VXLAN tunnel.
With continued reference to fig. 3, a flow 300 of one embodiment of a method for communicating information in accordance with the present disclosure is shown. The method for communicating information includes the steps of:
The content of step 301 is the same as that of step 201, and is not described in detail here.
The content of step 302 is the same as that of step 202, and is not described in detail here.
The content of step 303 is the same as that of step 203, and is not described in detail here.
When only one initial transmission path exists between the current node and the next node determined by the address information of the message forwarding device, the execution main body does not need to select the next node or select the transmission path between the next node and the execution main body. The execution body can directly set the transmission path as a transmission path, which is beneficial to accelerating the transmission speed of the message in the VXLAN tunnel.
When a plurality of initial transmission paths exist between the current node and the next node determined by the address information of the message forwarding device, in order to realize the requirements of special message transmission and the like between some terminals, the execution main body can select a transmission path from the plurality of initial transmission paths according to the hash factor. Therefore, the message can be transmitted between the terminals through the appointed transmission path, and the effective transmission of the message transmission is facilitated.
When a plurality of initial transmission paths exist between the current node and the next node determined by the address information of the message forwarding device, the execution main body may select the transmission path where the current maximum bandwidth exists to transmit the message. Therefore, the utilization rate of the bandwidth is improved, and the transmission speed and the transmission efficiency of the message in the VXLAN tunnel are facilitated.
The content of step 307 is the same as that of step 204, and is not described in detail here.
With continued reference to FIG. 4, a flow 400 of one embodiment of a method for communicating information in accordance with the present disclosure is shown. The method for communicating information includes the steps of:
In this embodiment, the execution subject of the method for transferring information (e.g., the intermediate node n.1, n.2, N.3 or the tail node N.4 shown in fig. 1) may receive the update virtual local area network (vlan) message through a wired connection or a wireless connection. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
And when receiving the updated virtual extended local area network message, the execution main body can analyze the updated virtual extended local area network message, and the hash factor and the message forwarding equipment address information on the outer layer of the updated virtual extended local area network message are analyzed from the updated virtual extended local area network message. That is, the execution main body of this embodiment may not have the capability of parsing the vlan packet, but only need to have the capability of parsing the hash factor. In this manner, the performance requirements on the execution body are reduced.
After obtaining the address information of the outer layer message forwarding device, the execution main body may select a transmission path between the current node and the next node according to the address information of the message forwarding device, and send the updated vlan packet to the next node through the transmission path.
In some optional implementation manners of this embodiment, the selecting a transmission path between the current node and the next node according to the address information of the packet forwarding device includes: and setting the initial transmission path as a transmission path in response to the fact that an initial transmission path exists between the current node and the next node determined by the address information of the message forwarding equipment.
The content of this implementation is similar to that of step 304, and is not described in detail here.
In some optional implementation manners of this embodiment, the selecting a transmission path between the current node and the next node according to the address information of the packet forwarding device includes: and responding to the existence of a plurality of initial transmission paths between the current node and the next node determined by the address information of the message forwarding equipment, and selecting a transmission path from the plurality of initial transmission paths according to the hash factor.
The content of this implementation is similar to that of step 305, and is not described in detail here.
In some optional implementation manners of this embodiment, the selecting a transmission path between the current node and the next node according to the address information of the packet forwarding device includes: and responding to the existence of a plurality of initial transmission paths between the current node and the next node determined by the address information of the message forwarding equipment, and selecting the transmission path according to the bandwidths of the plurality of initial transmission paths.
The content of this implementation is similar to that of step 306, and is not described in detail here.
In some optional implementations of this embodiment, the method may further include:
in the first step, in response to that the hash factor cannot be resolved from the updated virtual extended local area network message, the message receiving device address information of the inner layer of the updated virtual extended local area network message and the message forwarding device address information of the outer layer of the updated virtual extended local area network message are resolved from the updated virtual extended local area network message.
In practice, nodes within the VXLAN tunnel may not have the ability to resolve the hash factor. At this time, the execution main body needs to perform conventional data processing on the updated vlan message, and analyzes the address information of the message receiving device in the inner layer of the updated vlan message and the address information of the message forwarding device in the outer layer of the updated vlan message from the updated vlan message.
And secondly, selecting a transmission path between the current node and the next node according to the address information of the message forwarding equipment, and sending the updated virtual expanded local area network message to the next node through the transmission path.
After obtaining the address information of the message forwarding equipment, the execution main body selects a transmission path between the current node and the next node according to the address information of the message forwarding equipment, and sends the updated virtual extended local area network message to the next node through the transmission path. Therefore, the node without the Hash factor analysis capability can normally transmit the message, and the redundancy of the message transmission process is improved.
In some optional implementations of this embodiment, the method may further include: and responding to the correspondence between the current node and the address information of the message forwarding equipment, and sending the updated virtual extended local area network message to the message receiving equipment according to the address information of the message receiving equipment.
And when the current node corresponds to the address information of the message forwarding equipment, the current node is a tail node. At this time, the execution subject may send the updated vlan packet to the packet receiving device according to the address information of the packet receiving device. Therefore, message transmission between terminals is realized, and the message transmission efficiency is improved.
