Background
With the continuous development of network communication technology, the scale of an enterprise is larger and larger, a plurality of communication branches can be generally arranged in the enterprise, and the plurality of communication branches can realize enterprise service through network communication. In order to ensure the quality of service, an enterprise often purchases a dedicated network line from a network operator, and the network operator may provide the enterprise with a network access device deployed on the enterprise side for the enterprise to access the dedicated network line.
Typically, the network management department of the enterprise will assign different internal IP segments to different communication branches, such as 192.168.80.0/24 segment to enterprise communication branch 1 and 192.168.90.0/24 segment to enterprise communication branch 2. Meanwhile, the network management department may set a core switch in each enterprise communication branch, set the core switch as a gateway device of the enterprise device in the communication branch, and set the next hop device to other communication branches as a CE device on the core switch. Specifically, when a user (192.168.80.100) in the enterprise communication branch 1 accesses a server (192.168.90.50) in the enterprise communication branch 2, the specific transmission process of the access request may be as follows: subscriber terminal-core switch of communication branch 1-network access device of communication branch 1-dedicated network line-network access device of communication branch 2-core switch of communication branch 2-server.
In order to avoid the situation that a certain node in a certain network access device or a special network line fails to be interconnected between enterprise communication branches, a diversion server can be added into each original communication branch, and a bridge technology is adopted to establish a standby network line among the communication branches through the diversion server, so that the diversion server can guide data flow to be transmitted through the special network line or the standby network line to ensure interconnection among the communication branches. Therefore, in order to improve the guiding effect of the diversion server on the data traffic, a method for effectively detecting the line quality of the network line between the communication branches is needed, so that the diversion server can guide the data traffic according to the line quality.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a method for detecting line quality, which can be applied to a network architecture in which a plurality of communication branches are interconnected and is specifically realized by a diversion server deployed at each communication branch side. Each communication branch can contain a plurality of communication devices, the IP addresses of the communication devices in the same communication branch can belong to the same internal IP network segment, and the communication devices in the same communication branch can uniformly perform network communication with the communication devices of other communication branches through the gateway device of the communication branch.
A plurality of network lines may exist between every two communication branches, a diversion server may be deployed at each communication branch side, and the diversion server may be configured to receive data traffic of the communication branch where the diversion server is located, and perform processing such as guided offloading on the data traffic in the plurality of network lines according to a preset rule. Meanwhile, when the diversion server conducts guiding and shunting on data traffic, the diversion server can detect the line quality of a plurality of network lines and can update and adjust rules of guiding and shunting according to detection results.
The diversion server can include a processor, a memory, and a transceiver, wherein the processor can be used for executing the process of detecting the line quality in the following procedures, the memory can be used for storing the data required in the process and the generated data, and the transceiver can be used for receiving and transmitting the relevant data in the process. In the present embodiment, different communication branches of the same enterprise are taken as an example for description, and other scenarios are similar, and will be specifically described as necessary.
The process flow shown in fig. 1 will be described in detail below with reference to specific embodiments, and the contents may be as follows:
The first communication branch can be any communication branch which needs to be interconnected across branches in an enterprise, and the second communication branch can be any communication branch which needs to be in network communication with the first communication branch.
In implementation, a network manager of an enterprise may deploy a diversion server on each communication branch side of the enterprise, and make specific settings on the diversion server to implement guidance of data traffic through the diversion server. In the process of guiding the data flow, the flow guiding server can detect the line quality of the network line between the two communication branches, and adjust the guiding rule of the data flow in time based on the detection result.
Specifically, taking the first communication branch and the second communication branch as an example, multiple network lines may exist between the first communication branch and the second communication branch, and the multiple network lines may specifically exist between the diversion servers of the two communication branches. For any one of the network lines (e.g., the target network line), the first diversion server may configure a probe destination address, a probe source address, and a probe route corresponding to the target network line. The detection destination address and the detection source address corresponding to the target network line are the destination address and the source address in the detection request sent by the first diversion server when detecting the line quality of the target network line, and similarly, the detection route corresponding to the target network line is the routing rule used when the first diversion server sends the detection request.
And step 102, the first diversion server periodically generates a detection request based on the detection destination address and the detection source address, and sends the detection request to the second communication branch according to the detection route.
In implementation, after configuring the probe destination address, the probe source address and the probe route corresponding to the target network line, the first diversion server may periodically probe the line quality of the target network line based on the configuration content.
In particular, the first diversion server may periodically generate the probe request based on the probe destination address and the probe source address, i.e. the source IP address of the probe request is the probe source address and the destination IP address of the probe request is the probe destination address. Furthermore, the first diversion server may send the probe request to the second communication branch according to the probe route.
It should be noted that the diversion server periodically detects the line quality of each network line, the detection time and the detection cycle duration of each network line may be the same or different, different network lines may correspond to different detection cycle durations, for example, a network line with higher importance, the detection cycle duration may be shorter, for a network line that is nearly idle, the detection cycle duration may be longer, and the detection cycle duration of the same network line may also change, for example, when the network line fluctuation range is larger and the fluctuation frequency is higher, the detection cycle duration may be shortened, and when the network line is in a stable state for a long time, the detection cycle duration may be increased.
And 103, the first diversion server determines the line quality of the target network line according to the response state of the second communication branch to the detection request.
In an implementation, the first diversion server may continuously detect a response status of the second communication branch to the probe request after issuing the probe request to the second communication branch, so that the line quality of the target network line may be determined according to the detected response status.
Specifically, if the first diversion server receives the probe response fed back by the second communication branch, the first diversion server may evaluate the line quality of the target network line according to an interval duration between a sending time of the probe request and a receiving time of the probe response; if no probe response is received, a failure of the target network line may be determined. It is to be understood that the above description only shows an exemplary scheme for evaluating the line quality of the network line, and other schemes for evaluating the line quality according to the response status may also be applied to the present embodiment, and are not limited specifically herein.
Optionally, when detecting the line quality, the line quality of the network line may be determined by the response status of multiple probe requests at the same time, and correspondingly, the processing in step 103 may specifically be as follows: and the first diversion server determines the line quality of the target network line according to all the response states of the second communication branch to a plurality of detection requests with different detection destination addresses.
In implementation, when detecting for a target network line, the first diversion server may send a plurality of probe requests with different probe destination addresses to the second communication branch, and continuously detect a response status of the second communication branch for each probe request. When response messages of all the probe requests are received or a preset waiting time is reached, the first diversion server may determine the line quality of the target network line according to all the response states of the second communication branch to the plurality of probe requests.
Further, if there are a few special response states that do not match the response states of other probe requests in the response states of multiple probe requests, the first diversion server may reject the special response states or resend the probe requests corresponding to the special response states when determining the line quality of the target network line.
Optionally, the diversion server may employ a bridge technology to establish a plurality of network lines between the communication branches, and accordingly, a processing flow shown in fig. 2 may exist before step 101, and detailed descriptions may be as follows:
in step 201, the first diversion server creates a local virtual switch, and accesses the local virtual switch to the private network line of the first communication branch and the second communication branch.
In an implementation, the first diversion server may create a local virtual switch according to the program instruction, where the local virtual switch may be a bridge device implemented by the diversion server through software, such as a general bridge device created by a command "ip link add br0 type bridge" based on the linux system, a bridge device created based on the open source software OpenvSwitch, or a bridge device with link layer switching capability created based on any other software of the linux system.
The flow guidance server may then access the created local virtual switch to the private network line of the first communication branch and the second communication branch. It will be appreciated that if there are other communication branches in network communication with the first communication branch, the diversion server may also switch the local virtual switch to a dedicated network line between the first communication branch and the other communication branches.
In implementation, after the first diversion server creates the local virtual switch, a virtual network card may be created as a connection port with the local virtual switch, and an IP address may be configured for the virtual network card, where the IP address may belong to the same IP network segment as an IP address of the communication device in the first communication branch, so that the local virtual switch may transmit a part of the received data traffic to the diversion server through the virtual network card.
In step 203, the first flow guidance server creates at least one backup network link with a second flow guidance server of the second communication branch based on a network tunneling technique.
In implementation, the first diversion server and the second diversion server may be respectively provided with a tunnel virtual network card, and then, based on a network tunnel technology (such as vxlan and IPSEC technologies), a standby network line between the two diversion servers is created through the tunnel virtual network card, the tunnel virtual network card may serve as ports at two ends of the standby network line to be connected with the diversion servers, and the tunnel virtual network cards on the two diversion servers may be configured with virtual IP addresses of the same network segment. Furthermore, the first diversion server may set a local routing table of the IP layer, so as to determine, after receiving the data traffic output by the local virtual switch through the virtual network card, a standby network line corresponding to the data traffic according to the local routing table. It should be noted that each backup network line corresponds to a pair of tunnel virtual network cards, and if a plurality of backup network lines need to be created, a plurality of pairs of tunnel virtual network cards may be set on two diversion servers, and virtual IP addresses of the same network segment are configured for the two tunnel virtual network cards in each pair.
Fig. 3 schematically shows a network architecture diagram completed based on the processing setup of the above-described steps 201 to 203, in which one spare network line is shown, and a plurality of spare network lines are similar thereto.
Optionally, based on the network architecture in fig. 3, the configuration processing in step 101 may specifically be as follows: the first diversion server selects at least one communication device in the second communication branch, and sets the IP address of the at least one communication device as a detection destination address exclusive to the target network line; if the target network line is a private network line, the first diversion server sets a detection source address of the target network line as an IP address of a connection port of the local virtual switch and the first diversion server, and sets a next hop address in the detection route as an IP address of network access equipment of the private network line; if the target network line is a standby network line, the diversion server sets a detection source address corresponding to the target network line as an IP address of a home port of the standby network line, and sets a next hop address in the detection route as an IP address of an opposite port of the standby network line.
In an implementation, after the first diversion server establishes at least one backup network line with the second diversion server based on the bridge technology, the first diversion server may perform configuration of a probe destination address, a probe source address and a probe route for each network line (including the dedicated network line and the backup network line).
Still taking the target network line as an example, the first diversion server may select at least one communication device in the second communication branch as a probe responder dedicated to the target network line, and set the IP address of the at least one communication device as a probe destination address dedicated to the target network line, where the first diversion server is dedicated to be understood as a probe responder of each communication device only as one network line, that is, the IP address of each communication device is only used as a probe destination address of one network line. Then, if the target network line is a private network line, the first diversion server may set a detection source address corresponding to the target network line as an IP address of a connection port between the local virtual switch and the first diversion server, and set a next hop address in the detection route as an IP address of a network access device of the private network line; if the target network line is the standby network line, the diversion server may set the detection source address corresponding to the target network line as the IP address of the local port of the standby network line, and set the next hop address in the detection route as the IP address of the opposite port of the standby network line.
Optionally, the diversion server may also direct the probe response of the local side according to the probe destination address and the probe source address configured in the opposite-side communication branch, and the corresponding processing may be as follows: and the second diversion server configures a response guide rule on the local virtual switch according to the detection destination address and the detection source address corresponding to all the standby network lines configured by the first diversion server, and when receiving a detection response sent to the first diversion server by the communication equipment in the second communication branch, the second diversion server sends the detection response to the first communication branch through the special network line or the standby network line according to the response guide rule. Similarly, the first diversion server may also configure a response guidance rule on the local virtual switch for the detection destination address and the detection source address corresponding to all the network lines configured by the second diversion server. By responding to the configuration of the guide rule, the probe response can be ensured to return to the request end through the network line with the same probe request, so that the mapping relation between the probe task and the network line is established, and when the probe task is successful, the receiving and sending states of the network line are normal.
In implementation, after the first diversion server completes configuration of the probing destination addresses and the probing source addresses of all the standby network lines, the second diversion server may obtain a relevant configuration result, and then configure a response guidance rule on the local virtual switch according to the configuration result.
Specifically, the response guidance rule may include: and hooking the detection response of the detection source address of the destination IP address belonging to the standby network line to an IP layer for routing processing, and then transmitting the detection response through the corresponding standby network line. Thus, when receiving a detection response sent by the communication device in the second communication branch to the first diversion server, the second diversion server can select to send the detection response to the first communication branch directly through a dedicated network line or to hook the detection response to an IP layer for routing processing according to a response guidance rule configured on the local virtual switch, and then send the detection response to the first communication branch through a corresponding standby network line.
Optionally, the diversion server may further filter the received probe response according to the probe destination address and the probe source address corresponding to each network line, and the corresponding processing may be as follows: and when the detection response fed back by the second communication branch is received through the target network line, the first diversion server executes filtering processing on the detection response according to the target response filtering rule.
In implementation, after the first diversion server configures the detection destination address and the detection source address corresponding to the target network line, the target response filtering rule corresponding to the target network line may be configured according to the detection destination address and the detection source address. Specifically, the target response filtering rule may be: and only the detection response which is received through the target network line, the target IP address belongs to the detection source address corresponding to the target network line, and the source IP address belongs to the detection target address corresponding to the target network line is reserved. Therefore, when the detection response fed back by the second communication branch is received through the target network line, the first diversion server executes filtering processing on the detection response according to the target response filtering rule, so that the detection response which is transmitted by mistake due to line fault or opposite terminal configuration mistake can be filtered, and the accuracy of line quality detection is further improved.
In the embodiment of the invention, aiming at a target network line between a first communication branch and a second communication branch, a first diversion server of the first communication branch configures a detection destination address, a detection source address and a detection route corresponding to the target network line; the first diversion server periodically generates a detection request based on the detection destination address and the detection source address, and sends the detection request to the second communication branch according to the detection route; and the first diversion server determines the line quality of the target network line according to the response state of the second communication branch to the detection request. Therefore, for each network line between two communication branches, by binding respective detection parameters, when the line quality of a certain network line needs to be detected, a detection request can be accurately sent to the opposite terminal through the network line, and the line quality of the corresponding network line can be effectively detected according to the response state of the detection request.
