The packet optimization method according to the first embodiment of the present invention is applied to a terminal, and a plurality of terminal devices are in communication connection with a server, and in this embodiment, the packet optimization method includes:
step S100, acquiring the total amount of VTEP nodes in a virtual extensible local area network VxLAN and IP addresses corresponding to the VTEP nodes;
in this embodiment, VXLAN is a network virtualization technology, which can improve the problem of expansion of large cloud computing during deployment, and is an expansion of VLAN. VXLAN is a powerful tool that can extend two layers across a three-layer network. It can address the portability limitation of VMS (virtual memory system) by encapsulating traffic and extending it to a third tier gateway, making it accessible to servers on external IP subnets.
As described above, the packets encapsulated by VXLAN are usually sent in a unicast manner between VTEP nodes having the same VNI, and the group leader in each VTEP group needs to unicast the packets to other VTEP nodes in the group. VTEP grouping schemes typically group automatically according to network segments, or manually. Manual grouping can be reasonably well distributed, but requires manual configuration, which is complicated. The nodes of the VTEP are automatically grouped according to the network segment, so that the phenomenon of unreasonable grouping can occur to the nodes of the VTEP, the load of part of VTEP group lengths is high due to the grouping of the VTEP, performance bottleneck occurs, and the performance of each node can not be fully exerted. In order to solve the problems, the invention provides a packet optimization method, which carries out secondary grouping on VTEP nodes in the VxLAN according to the primary quantity and the secondary quantity, realizes balanced grouping of VETP nodes, realizes that each VTEP node shares unicast message load of a VTEP group length based on a preset rule, and improves the network performance of the VxLAN.
Specifically, in order to reasonably group the VETP nodes, the number of all VTEP nodes, that is, the total number of VTEP nodes, is obtained in the virtual extensible local area network VxLAN, and the IP addresses corresponding to the VTEP nodes are obtained.
Step S200, determining the primary quantity and the secondary quantity based on the total quantity of the VTEP nodes;
in this embodiment, first-stage grouping is performed on all VTEP nodes in the virtual extensible local area network VxLAN, and then second-stage grouping is performed in each first-stage grouping, where the number of VTEP nodes included in each first-stage grouping is equal to the number of first stages, and the number of VTEP nodes included in each second-stage grouping is equal to the number of second stages. And determining the primary quantity and the secondary quantity according to the total quantity of the VTEP nodes.
Specifically, step S200 includes:
step S210, acquiring a preset grouping comparison table;
step S220, searching and obtaining the primary quantity and the secondary quantity corresponding to the total quantity of the VTEP nodes in the preset grouping comparison table.
In this embodiment, grouping the VTEP nodes and performing the second-stage grouping are performed to realize that each VTEP node shares the unicast packet load of the VTEP group length, so it is particularly critical how to determine a reasonable first-stage number and second-stage number.
Specifically, the primary quantity and the secondary quantity determining method may be: performing primary grouping according to the total number of VTEP nodes by using an exhaustion method, and if the total number is averagely divided into 2 groups, 3 groups, 4 groups and 5 groups, performing secondary grouping on the primary grouping, averagely dividing the primary grouping into 2 groups, 3 groups and 4 groups, counting the sum of unicast times of the primary VTEP group under the respective grouping conditions, selecting the grouping condition with the minimum unicast times, and recording the number of VTEP members in the primary grouping as the primary number; and recording the number of VTEP members in the second-level grouping as a second-level number, and storing the total number of VTEP nodes, the first-level number and the second-level number in a preset grouping comparison table in an associated manner.
When the primary quantity and the secondary quantity are determined according to the total quantity of the VTEP nodes, the corresponding primary quantity and the corresponding secondary quantity are searched in the preset grouping comparison table according to the total quantity of the VTEP nodes by acquiring the preset grouping comparison table.
Step S300, performing primary grouping and secondary grouping on the VTEP nodes in the VxLAN based on the primary number, the secondary number and the IP addresses corresponding to the VTEP nodes respectively;
in this embodiment, the VTEP nodes are sorted first, and then are grouped in the first stage according to the first-stage number, and then are grouped in the second stage according to the second-stage number.
Specifically, step S300 includes:
step S310, sorting the VTEP nodes based on the respective corresponding IP addresses of the VTEP nodes to obtain sorted VTEP nodes;
in this embodiment, the IP address is used to identify a device on the network, and therefore, the IP address is composed of two parts, namely a network address and a host address. The network address may be used to identify the network on which the device is located, the network address being located in the front part of the IP address. When an organization or enterprise applies for an IP address, the obtained IP address is not a unique and identifiable network address. All devices on the same network have the same network address. The host address is located in the back segment of the IP address and can be used to identify devices on the network. Devices on the same network all have the same network address, and the devices are distinguished by host addresses.
Specifically, the VTEP nodes are sorted according to the respective corresponding IP addresses of the VTEP nodes, that is, host addresses of the VTEP nodes are sorted in an ascending order or a descending order to obtain sorted VTEP nodes, and each VTEP node is matched with an ID number, for example, the first VTEP node starts with a number of 1, 2, 3, and the corresponding VTEP node is denoted as VTEP1, VTEP2, VTEP 3.
And step S320, performing primary grouping and secondary grouping on the sorted VTEP nodes based on the primary quantity and the secondary quantity.
Specifically, step S320 includes:
step S321, based on the first-level number, performing average grouping on the sorted VTEP nodes to obtain each first-level group, wherein the number of the VTEP nodes in the first-level group is equal to the first-level number;
step S322, respectively performing secondary grouping on each primary grouping based on the secondary quantity to obtain each secondary grouping.
Specifically, step S322 includes: and respectively carrying out average grouping on each first-level group based on the second-level number to obtain a second-level group corresponding to each first-level group, wherein the number of VTEP nodes in the second-level group is equal to the second-level number.
In this embodiment, the first-stage grouping and the second-stage grouping are performed on the sorted VTEP nodes according to the first-stage number and the second-stage number, and the specific process is as follows: firstly, carrying out primary grouping on VTEP nodes, and taking a primary quantity of VTEP nodes as a first primary group from a first VTEP node in the sequenced VTEP nodes, and then taking a primary quantity of VTEP nodes as a second primary group, so as to realize the primary grouping on the VTEP nodes according to the rule; then, each first-level grouping is subjected to second-level grouping, the grouping rule is the same as that of the first-level grouping, namely, in one first-level grouping, from the first VTEP node, the VTEP nodes with the second quantity are taken as the first second-level grouping, and then the VTEP nodes with the second quantity are taken as the second-level grouping, so that the second-level grouping of the VTEP nodes is realized according to the rule.
Step S400, respectively determining a primary VTEP group length corresponding to each primary group and a secondary VTEP group length corresponding to each secondary group based on a preset rule.
In the present invention, the primary VTEP group leader of each primary group also serves as the secondary group leader within its corresponding secondary group. When a VTEP node receives a message, the message is firstly sent to a primary VTEP group leader of a primary group where the VTEP node is located, the primary VTEP group leader respectively unicasts the received message to each secondary VTEP group leader in the primary group, and the secondary VTEP group leader respectively unicasts the message to other VTEP nodes in the secondary group. In order to balance the unicast message load of the VTEP group leader, a primary VTEP group leader and a secondary VTEP group leader are respectively assigned under different VTEP nodes.
The packet optimization method provided in this embodiment obtains a total amount of VTEP nodes in a VxLAN of a virtual extensible local area network and IP addresses corresponding to the respective VTEP nodes, then determines a primary number and a secondary number based on the total amount of the VTEP nodes, then performs primary grouping and secondary grouping on the VTEP nodes in the VxLAN based on the primary number, the secondary number and the IP addresses corresponding to the respective VTEP nodes, and finally determines a primary VTEP group length corresponding to each primary grouping and a secondary VTEP group length corresponding to each secondary grouping based on a preset rule. And performing secondary grouping on the VTEP nodes in the VxLAN according to the primary quantity and the secondary quantity to realize balanced grouping of the VETP nodes, realizing that each VTEP node shares the unicast message load of the VTEP group length based on a preset rule, and improving the network performance of the VxLAN.
Based on the first embodiment, referring to fig. 3, a second embodiment of the packet optimization method of the present invention is proposed, in this embodiment, step S400 includes:
step S410, determining a primary VTEP group length of each primary group corresponding to each VTEP node based on the position number of each VTEP node;
step S420, based on the position number of each VTEP node, determining the second-level VTEP group length of the second-level group corresponding to each first-level group.
In the present invention, the primary VTEP group leader of each primary group also serves as the secondary group leader within its corresponding secondary group. In order to balance the unicast message load of the VTEP group leader, a primary VTEP group leader and a secondary VTEP group leader are respectively assigned under different VTEP nodes.
Specifically, after the sorted VTEP nodes are sorted, each VTEP node is matched with an ID number, the ID numbers are 1, 2 and 3 from the first VTEP node, remainder taking operation is carried out by using the ID numbers and the first-level number, the obtained remainder is used as the ID number of the first-level VTEP group leader, and the VTEP node corresponding to the ID number of the first-level VTEP group leader is the first-level VTEP group leader of the first-level group. And acquiring the position number of the primary VTEP group length in the corresponding primary group, and correspondingly determining the primary VTEP group lengths of other primary groups. And meanwhile, the primary VTEP group leader also serves as a secondary group leader in the corresponding secondary group, the position number of the primary VTEP group leader in the corresponding secondary group is obtained, and the secondary group leader of other secondary groups in the primary group is correspondingly determined.
For example, as shown in fig. 4, 18 VTEP nodes, the number of levels being equal to 6, the number of levels being equal to 3, are divided into 3 level-one packets, each level-one packet including 6 VTEP nodes, and each VTEP level-one packet is divided into 2 level-two packets, each level-two packet including 3 VTEP nodes. The ID number of VTEP1 is 1, so the remainder is 1 by performing remainder-taking operations with 1 and the number of one level 6, and therefore VTEP1 is the length of the VTEP group at one level of the packet where it is located, and the number of the VTEP node at the position of the packet at one level is 1, so the first VTEP node of other packets at one level is also the length of the VTEP group at one level, that is, the length of the VTEP group at one level of the second packet at one level is VTEP7, and the length of the VTEP group at one level of the third packet at one level is VTEP 13. Meanwhile, VTEP1 is also the second-level VTEP group length of the second-level packet where it is located, and its position number in the second-level packet is 1, so the first VTEP node of other second-level packets is also the second-level VTEP group length, that is, the second-level VTEP group length of the second-level packet is VTEP 4. And determining other secondary VTEP group leader by the same method.
Further, the primary VTEP group leader unicasts the received packets to each secondary VTEP group leader in the primary group, and the secondary VTEP group leader unicasts the packets to other VTEP nodes in the secondary group.
In this embodiment, when a VTEP node receives a packet, it first sends the packet to a primary VTEP group leader of a primary group where the VTEP node is located, the primary VTEP group leader unicasts the received packet to each secondary VTEP group leader in the primary group, and the secondary VTEP group leader unicasts the packet to other VTEP nodes in the secondary group. For example, VTEP1 message replication flow.
1. The VTEP1 node respectively unicasts the message to a primary packet group leader VTEP7 and VTEP 13;
2. after receiving the message, the first-level group leader unicasts the message to the second-level group leader;
level one packet 1(L1 group 1) unicasts packets to VTEP4
Level one packet 2(L1 group 2) unicasts packets to VTEP10
Level one packet 3(L1 group 3) unicasts packets to VTEP16
3. After receiving the message, the second-level grouping leader unicasts the message to the second-level grouping member respectively;
the VTEP1 unicasts the message to VTEP2 and VTEP3 respectively
The VTEP4 unicasts the message to VTEP5 and VTEP6 respectively
The VTEP7 unicasts the message to VTEP8 and VTEP9 respectively
The VTEP13 unicasts the message to VTEP14 and VTEP15 respectively
The VTEP16 unicasts the message to VTEP17 and VTEP18 respectively
The packet optimization method provided in this embodiment determines, based on the position number of each VTEP node, a primary VTEP group length of each primary packet corresponding to each VTEP node, and then determines, based on the position number of each VTEP node, a secondary VTEP group length of a secondary packet corresponding to each primary packet. By respectively appointing the primary VTEP group length and the secondary VTEP group length under different VTEP nodes, the VTEP nodes share the unicast message load of the VTEP group length, and the VxLAN network performance is improved.
