Description
Technical Field
The present invention relates to communication technologies, and in particular, to a method and an apparatus for network port backup and multiplexing.
Background
In the broadband cluster core network, network elements such as an MME, an HSS, an SGW, a PGW, a TCF, a TMF, a CG, a PCRF, an SGSN and the like need to be deployed, external interfaces include interfaces such as S1-MME, S1-U, S11, S3, S4, S5, S6a, S8, S10, S11, S12, SGi, D1-U, Ta and the like, and the number of the network elements and the number of the interfaces are large.
The external interface of the network element is used for information interaction with other network elements. The external interface is represented by an external IP and a port, and the reliability of the external interface depends on the stability of the network port. If the network port has the problems of network cable looseness, network port faults and the like, the external interface can be failed. The loose network cable and the network port fault are common faults, and the reliability of the network element interface needs to be considered and considered.
For ensuring the reliability of the external interface, there are two common methods at present:
the first method is to perform redundancy backup on the network element or perform redundancy backup on a server where the network element is located.
The backup server or backup network element is typically deployed on a different board or server. When the working network element interface has a fault, the backup network element takes over. In this way, the problem of interface failure can be effectively solved.
In the process of implementing the present invention, the inventor finds that the first method has the following disadvantages:
1. the system is complex, and in order to achieve uninterrupted service during network element switching, complex data synchronization work needs to be performed between the working network element and the backup network element/server, so that the resource overhead is high.
2. An additional board or server is required to deploy the backup network element, so the implementation cost is high.
And secondly, deploying the network element on server equipment with the function of double network ports.
The network element interface is deployed on the server equipment with the function of double network ports, and when the working network port fails, the hardware layer of the server is automatically switched to the backup network port.
In the process of implementing the invention, the inventor finds that the second method has the following disadvantages:
1. server support with this functionality is required.
2. Only two network ports can be mutually used as main and standby network ports, and if the number of interfaces needing to be backed up is more than that of the network ports, the network ports are not enough.
3. The two network ports are actually equivalent to one network port, and the two network ports cannot be used separately, so that the utilization rate of network port resources is low, and the implementation cost is high.
Therefore, the existing network port backup scheme has the problems of high implementation cost, low resource utilization rate, complex implementation and the like.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is as follows: and selecting the best standby network port from the standby network ports by adopting a self-adaptive selection strategy, and switching the network element interface to the best standby network port when the network port where the network element interface is positioned fails. The standby network port can be one or a plurality of, and under the condition that the network links are consistent, the standby network port can be multiplexed among a plurality of interfaces, so that the utilization rate of the network port can be improved, and the implementation cost is effectively reduced.
Fig. 1 is a schematic flow chart of a method according to an embodiment of the present invention, and as shown in fig. 1, the method for backing up and multiplexing an internet access implemented by the embodiment mainly includes:
This step is used for the initial configuration of the working network port and the backup network port when the network element is started.
Preferably, the following method can be adopted to determine the working port and the backup port used by the local network element when the network element is started:
if the network element has a preset working network port and a preset backup network port, setting the working network port of the network element as the preset working network port, and setting the backup network port of the network element as the preset backup network port, otherwise, determining an available network port in the network ports of the server or the single board where the network element is located, calculating the network port performance value of each available network port, selecting the network port with the highest network port performance value as the working network port of the network element, and taking all the available network ports which are not selected as the backup network ports of the network element.
In the method, if the working network port and the backup network port are set for the network element in advance, the configuration is directly performed based on the preset network port configuration information, and if the working network port and the backup network port are not set for the network element, the performance condition of each network port of the server or the single board where the network element is located needs to be considered, and the network port with the best performance is selected as the working network port, so that the working performance of the network element can be ensured.
Meanwhile, the other available network ports except the available network port with the best performance on the server or the single board where the network element is located are used as backup network ports. Thus, in the subsequent operation process of the network element, if a fault occurs, the network port with the best performance can be selected from the backup network ports as many as possible to serve as a new working network port, so as to enhance the reliability of the network element. On the other hand, multiplexing of the network ports is also realized, that is, for network element interfaces with consistent network links, the same network port can be used as a backup network port for the interface a and also can be used as a backup network port for the interface B, so that the utilization rate of network port resources can be fully improved, and the working network port of the network element can be switched to the network port with better performance when the network element fails, so as to increase the reliability of the network element.
In practical application, the availability of the network port can be realized by adopting a conventional method, namely, whether the network port has a fault or not can be judged firstly, if no fault exists, an IP (internet protocol) which is in the same network segment as the interface is used as a source IP at the network port (if the network port does not have the IP in the same network segment, a specific IP is loaded), and whether the network port can be reached or not is checked through ping a target IP.
Specifically, the method for determining a network port fault may be: and judging whether the connection of the network cable is disconnected or not according to the fact that the Link protected state of the network port is yes or no.
Preferably, in the embodiment of the present invention, for a port, the port performance value can be calculated by the following method:
and calculating the network port performance value according to network port performance (network port sending data flow/network port bandwidth) multiplied by a first weight + (network port receiving data flow/network port bandwidth) multiplied by a second weight + (target IP reachable time/maximum reachable time) multiplied by a third weight, wherein the first weight + the second weight + the third weight is 1.
In the method, the network port performance value is calculated by multiplying each parameter such as the data traffic sent by the network port, the data traffic received by the network port, the target IP reachable time and the like by the corresponding weight.
The first weight, the second weight and the third weight can be set to appropriate values by those skilled in the art according to the importance of the corresponding parameters in actual use. If the weight is zero, the parameter is not detected.
In this step, the specific method for loading the network configuration information of the network element interface to the working network port is the same as the existing method, that is, resources such as an ip port and a route of the network element interface are loaded to the corresponding working network port, and details are not repeated.
And step 102, after the start is completed, the network element detects the working network port and the backup network port of the network element according to a preset detection period, determines whether the switching of the working network port needs to be triggered according to a detection result, and switches the working network port to the standby network port with the best current performance if the switching of the working network port needs to be triggered.
The step is used for periodically detecting the operation conditions of the working network port and the backup network port of the network element so as to trigger the switching of the working network port in time when the working network port has problems and select the standby network port with the best performance as a new working network port to ensure the normal receiving and sending of the network element data.
The detection period is used to limit the time interval of the detection, and a suitable value can be set by a person skilled in the art according to actual needs.
Preferably, the following method may be adopted to detect the working port and the backup port in this step:
and for the working network port and each backup network port, detecting whether the network port has a fault, and if not, calculating the current network port performance value of the network port.
Preferably, the calculation of the network port performance value is the same as the calculation method adopted in step 101, and is not described herein again.
Preferably, in order to increase the accuracy of the switching and avoid the ping-pong phenomenon of the switching, the following method may be adopted to determine whether the switching of the working network port needs to be triggered according to the detection result:
and if the working network port is detected to have a fault and the fault duration reaches a preset time threshold, triggering the switching of the working network port, otherwise, not triggering the switching of the working network port.
Specifically, the following method can be adopted to switch the working network port to the standby network port with the best current performance, including:
unloading network configuration information (such as IP, socket and other resources) of the network element interface from the working network port; and loading the network configuration information (such as IP, socket and other resources) of the network element interface to the standby network port with the best current performance.
The switching of the working network ports is realized by the method, then, the network element interface continuously sends the data to be sent in the buffer queue through the switched network ports, and the network element interface receives the new message through the switched network ports.
As can be seen from the method embodiment, the technical scheme has the following advantages:
1. the system is simple, for the fault of the network port type of the network element interface, the switching to the redundant backup network element is not needed, the data synchronization between the working network element and the backup network element is not needed, the data can be directly continuously forwarded during the recovery of the network port, and the stability during the recovery of the fault is higher.
2. The method is adaptive and intelligent, and can adaptively select a working network port and a backup network port, and when a network element is started and a network port where a network element interface is located has a fault, the working network port and the backup network port are selected from the backup network ports by adopting an adaptive selection strategy.
3. The system has high reliability, can realize redundant backup of multiple network ports, can make a backup network port for a main network port (a working network port) to form a main network port and a spare network port, and can also backup the main network port (the working network port) at the multiple network ports to form multiple backup network ports of the main network port (the working network port).
4. The network port utilization rate is high, and the backup network port can be reused. Under the condition of consistent network links, the backup network port divided into the interface A can be used by the interface B as a working network port or a backup network port.
