In data center applications, traffic needs to be directed to different servers for processing through load balancing. Meanwhile, the operation of flexibly increasing and decreasing the servers is needed according to the load condition of the current server, and the operation of increasing and decreasing the servers is the addition and deletion of the member ports for the load balancing member table.
When the member ports are added and deleted, the server accessed by the existing traffic is affected, so that the customer experience is deteriorated, and therefore, the session is significant in the scene.
In view of the above-mentioned problems, the present embodiment provides a session maintaining method, apparatus, electronic device, and storage medium, where the session maintaining method, apparatus, electronic device, and storage medium are capable of obtaining a reference list by determining all member ports for maintaining a traffic session, ordering the member ports in order, and repeating N times, where when there are dropped member ports in the reference list, determining a member port to be replaced, replacing the dropped member port based on the member port to be replaced and the reference list, obtaining an online member list, and maintaining the traffic session based on the online member list. When the number of the member ports of the member group where the current flow is located is changed, the member ports selected by the current flow are unchanged, when the member ports selected by the current flow are dropped, the current flow can be uniformly distributed on other member ports in an online state, and when the number of the member ports of the group is increased (or the member ports which are dropped before are restored to the online state at present), the route selection of the flow which is forwarded at present is not affected. The invention can also be realized by a relatively simple method, and the session holding can be realized by software on hardware equipment which does not support the session holding, and the scheme provided by the embodiment is explained in detail below.
The embodiment provides an electronic device capable of holding a session. In one possible implementation, the electronic device may be a user terminal, for example, the electronic device may be, but is not limited to, a server, a smart phone, a personal computer (PersonalComputer, PC), a tablet, a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet device (Mobile Internet Device, MID), or the like.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the disclosure. The electronic device 100 may also include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The electronic device 100 comprises session holding means 110, a memory 120 and a processor 130.
The memory 120 and the processor 130 are electrically connected directly or indirectly to each other to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The session maintaining means 110 comprises at least one software function module which may be stored in the memory 120 in the form of software or firmware (firmware) or cured in an Operating System (OS) of the electronic device 100.

Referring to fig. 2, fig. 2 is a flowchart of a session maintaining method applied to the electronic device 100 of fig. 1, and the method includes steps described in detail below.
Step 201: all member ports for forwarding the traffic session are determined.
Step 202: the member ports are ordered in sequence and repeated N times to obtain a reference ordered list.
Step 203: and when the dropped member ports exist in the reference list, determining the member ports to be replaced.
Step 204: and replacing the dropped member port based on the member port to be replaced and the reference list to obtain an online member list.
Step 205: the traffic session is maintained based on the online member ranking list.
All member ports forward the traffic session.
It should be noted that when the load balancing has N member ports, the number of member ports recorded and informed to the hardware by the software is not just N. This ensures a more uniform replacement.
In one example, when the number of member ports is 6, including member port 0, member port 1, member port 2, member port 3, member port 4, and member port 5, the ordering is in order based on the member ports. For example, the number of member ports recorded in the software and notified to the hardware is 16, and as shown in fig. 3, the reference arrangement of 6 member ports represents the intention, where the reference arrangement list includes member ports as member ports 0, 1, 2, 3, 4, and 5. And in the order 0123450123450123.
When a certain member port in the reference list drops, determining a member port to be replaced, wherein the member port to be replaced is used for replacing the dropped member port in the reference list to obtain an online member list, and processing the traffic session based on the online member list, so that the traffic of the online member port is ensured not to change.
There are various implementations for determining a member port to be replaced, and in one implementation, as shown in fig. 4, the method includes the following steps:
step 301: and when the dropped member ports exist in the reference list, eliminating the dropped member ports from all the member ports to obtain the online member ports.
Step 302: the online member port is used as a member port to be replaced.
In an example, when the member port 0 is a dropped member port in the reference list shown in fig. 3, and all the member ports included in the reference list are the member port 0, the member port 1, the member port 2, the member port 3, the member port 4 and the member port 5, the dropped member port 0 is removed from all the member ports, so as to obtain the member port 1, the member port 2, the member port 3, the member port 4 and the member port 5, and the member port 1, the member port 2, the member port 3, the member port 4 and the member port 5 are online member ports, and the online member port is used as a member port to be replaced, and the dropped member port is replaced based on the member port to be replaced.
There are various implementations of determining online member listings, in one implementation, as shown in FIG. 5, including the steps of:
step 204-1: and determining the target online member port adjacent to the last offline member port in the reference list.
Step 204-2: and ordering the online member ports by taking the target online member ports as the head, and obtaining the online member port arrangement sequence.
Step 204-3: and replacing each online member port in the reference list by each online member port in the online member port arrangement sequence in sequence to obtain an online member list.
Based on the specific manner of replacing each dropped member port in the reference list in the online member port arrangement order, this embodiment is exemplified in the case where the number of dropped member ports is one and the number of dropped member ports included in the reference list is two.
The specific alternative modes comprise: the target online member port is determined from the online member port ranking order. And replacing the first target dropped member port in the reference list with the target online member port. The next online member port of the target online member port is determined in the online member port ranking order. And replacing a second target dropped member port in the reference list with a next online member port of the target online member port to obtain an online member list.
In an example, when the reference list is the reference list as shown in fig. 3 and the dropped member port is the member port 2, it is determined that the target online member port adjacent to the last dropped member port 2 in the reference list is the member port 3. And taking the target online member port as the head, namely taking the member port 3 as the head, and sequencing all online member ports to obtain the online member port arrangement sequence, namely, the online member port arrangement sequence is 3, 4, 5, 0 and 1. And replacing each drop member port in the reference list by each online member port in the online member port arrangement sequence in turn, for example, replacing a first drop member port in the reference list by an online member port 3 in the online member port arrangement sequence, replacing a second drop member port in the reference list by an online member port 4 in the online member port arrangement sequence, replacing a third drop member port in the reference list by an online member port 5 in the online member port arrangement sequence, and replacing each drop member port in the reference list by each online member port in the online member port arrangement sequence until all drop member ports in the reference list are replaced, thereby obtaining the online member list.
In another example, when the reference list is as shown in fig. 3 and the dropped member ports are the member port 2 and the member port 3, determining that the target online member port adjacent to the last dropped member port 3 in the reference list is the member port 4, and ordering all online member ports by taking the target online member port as the head, namely taking the member port 4 as the head, to obtain an online member port arrangement sequence, namely, the online member port arrangement sequence is 4, 5, 0 and 1. Replacing each online member port in the reference list in turn by each online member port in the online member port arrangement sequence, for example: the method comprises the steps of replacing a dropped member port 2 ordered at the tail of a table in a reference ranking list with an online member port 4 in an online member port ranking sequence, replacing a dropped member port 3 ordered at the tail of the table in the reference ranking list with an online member port 5 in the online member port ranking sequence, ordering a dropped member port 2 at the head end in the reference ranking list with an online member port 0 in the online member port ranking sequence, and ordering a dropped member port 3 at the head end in the reference ranking list with an online member port 1 in the online member port ranking sequence. And obtaining the online member list after all the dropped member ports in the reference list are replaced completely.
In another example, when the reference list is as shown in fig. 3 and the dropped member ports are the member port 2 and the member port 3, determining that the target online member port adjacent to the last dropped member port 3 in the reference list is the member port 4, and ordering all online member ports by taking the target online member port as the head, namely taking the member port 4 as the head, to obtain an online member port arrangement sequence, namely, the online member port arrangement sequence is 4, 5, 0 and 1. Replacing each online member port in the reference list in turn by each online member port in the online member port arrangement sequence, for example: the online member ports 4 in the online member port arrangement sequence are replaced with the reference list and are ranked in the first offline member port 2, the online member ports 5 in the online member port arrangement sequence are replaced with the second offline member ports 3 in the reference list, the online member ports 0 in the online member port arrangement sequence are replaced with the reference list and the third offline member ports 2, and the online member ports 1 in the online member port arrangement sequence are replaced with the fourth offline member ports 3 in the reference list. And obtaining the online member list after all the dropped member ports in the reference list are replaced completely.
In another implementation of determining an online member ranking list, as shown in FIG. 6, the method comprises the steps of:
step 204-5: and determining a target standby member port corresponding to the dropped member port.
Step 204-6: and determining the sequence of the standby member ports in the target standby member ports.
Step 204-7: and replacing each dropped member port in the reference list in turn based on each standby member port in the standby member port sequence to obtain the online member list.
In one example, different dropped member ports are set to correspond to different spare member ports. For example: the spare member ports of the member port 0 are set as the member port 1 and the member port 3, the spare member ports of the member port 1 are set as the member port 0, the member port 2 and the member port 3, the spare member ports of the member port 1 are set as the member port 0 and the member port 3, and the spare member ports of the member port 3 are set as the member port 0 and the member port 2.
As shown in fig. 7, the reference arrangement of 4 member ports represents an intention, and the reference arrangement list in the figure includes member port 0, member port 1, member port 2, and member port 3, and the order is 0123012301230123.
When the member port 1 is a dropped member port, the standby member port corresponding to the member port 1 is determined, that is, the target standby member port corresponding to the dropped member port 1 is the member port 0, the member port 2 and the member port 3. And sequentially replacing each member port 1 in the reference list with the target standby member port to obtain an online member list.
In an example, when the member port 1 and the member port 2 are both dropped member ports, the spare member ports corresponding to the member port 1 and the spare member ports corresponding to the member port 2 are determined, that is, the member port 0, the member port 2 and the member port 3 are determined as first target spare member ports, and the member port 0 and the member port 3 are determined as second target spare member ports, because the member port 2 is a spare member port of the member port 1, the member port 2 is a dropped member port, and the first target spare member port and the second target spare member port are both the member port 0 and the member port 3. And sequentially replacing each member port 1 and each member port 2 in the reference list by the member port 0 and the member port 3. The order of the online member list is 0033003300330033.
In another example, the member ports 0 and 3 are used as the first target standby member ports, the member ports 0 and 3 are used as the second target standby member ports, the member ports in the first target standby member ports are sequentially replaced with the dropped member port 1, the member ports in the second target standby member ports are sequentially replaced with the dropped member port 2, and the obtained online member rank list is 0003033300030333.
When all drop ports are restored to the online state, the implementation manner of changing the online member list is changed, as shown in fig. 8, and includes the following steps:
step 401: and when the dropped member port is restored to the online state, determining the position corresponding to the dropped member in the reference list.
Step 402: based on the location, a target member port matching the location is determined in the online member list.
Step 403: and replacing the dropped member port with the target member port.
In one example, when the reference list is as shown in fig. 3, the member port order of the reference list is 0123450123450123, and the drop member port is member port 2, the online member list order is 0143450153450103. The corresponding locations of the drop member ports 2 are determined in the reference list to be location 3, location 9 and location 15. The target member ports corresponding to the position 3, the position 9 and the position 15 in the online member arrangement table are determined to be the target member port 4, the target member port 5 and the target member port 0 respectively. The dropped member port 2 is replaced with the target member port 4, the target member port 5, and the target member port 0, respectively.
In another example, when the reference list is as shown in fig. 3, and the dropped member ports are member port 2 and member port 3, the online member list order is 0101450145450145.
When the dropped member port 2 is restored to the online state, determining that the corresponding position of the dropped member port 2 is position 3, position 9 and position 15 in the reference list, determining that the corresponding target member ports of position 3, position 9 and position 15 in the online member list are target member port 0, target member port 4 and target member port 4, replacing the dropped member port 2 with the target member port 0, target member port 4 and target member port 4 respectively to obtain a first member port list, wherein the arrangement order of the first member port list is 0121450125450125, determining that the corresponding position of the dropped member port 3 is position 4, position 10 and position 16 in the first member port list based on the first member port list and the reference list, namely, based on the reference list 0123450123450123, and determining that the corresponding member ports of position 4, position 10 and position 16 in the first member port list are member ports 1, member port 5 and member port 5, and determining that the online member port arrangement order is when the member port 2 is restored to the online state: 0145, replacing the member port 0 corresponding to the first member port list position 4 with the member port 0 in the online member port arrangement sequence, replacing the member port 5 corresponding to the first member port list position 10 with the member port 1 in the online member port arrangement sequence, replacing the member port 5 corresponding to the first member port list position 16 with the member port 2 in the online member port arrangement sequence, obtaining a second member port list, and processing the traffic session based on the second member port list.
It should be noted that, the modulus value of each member port in the second member port list is consistent with the modulus value of each member port in the reference list, so that when the member port is dropped, the route selection of the current forwarded flow is not affected. .
