The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.

FIG. 1 is a schematic diagram of a shunt device test system for use with embodiments of the present disclosure.

Referring to fig. 1, a system 100 may include:

a routing device 11;

the primary shunting device 12 is connected with the routing device 11;

the secondary shunting device 13 is connected with the primary shunting device 12, and is provided with a plurality of server output ports 131, and the plurality of server output ports 131 are grouped according to services;

a plurality of servers 14, wherein each server 14 is correspondingly connected with one server output port 131;

the test device 15 is connected to the secondary shunt device 13, and is used in the shunt device test method provided by the embodiment of the present disclosure to test whether the shunt function and the copy function of the secondary shunt device 13 are normal.

In the system 100, the routing device 11 may be, for example, a router or a switch. The routing device 11 receives the service packet and forwards the service packet to the primary offloading device 12.

The primary offloading device 12 determines which service or services the service packet is processed by according to the attribute of the service packet. When one service packet corresponds to a plurality of services, the primary offloading device 12 generates an MAC address code designating a computing unit (i.e., designates which CPU core of which server corresponding to which service the service packet is processed), and issues the MAC address code and the service packet to the secondary offloading device 13.

The secondary shunting device 13 is, for example, a shunting switch. After receiving the service message and the MAC address code thereof, the secondary offloading device 13 parses the MAC address code, and when determining that the service message only relates to one service, offloads the service message to a server output port of a designated server corresponding to the service according to information of the MAC address code, and specifies which CPU core of the designated server processes the service message; when the service message is judged to relate to a plurality of different services, the service message is copied, the copied service message is distributed to a server output port of a designated server corresponding to the service, and the CPU core of the designated server is designated to process the service message.

The server 14 receives and processes the service message through the corresponding server output port.

The MAC address code generated by the primary offload device 12 consists of SMAC (source MAC address) and DMAC (destination MAC address). In general, the MAC address coding formed by the SMAC and the DMAC together can accommodate the processing information of 8 services, and the number of information bits corresponding to each service is not exactly the same. The information corresponding to each service consists of a server serial number (numbered from 1) and a server network card ring number (numbered from 0), the first-stage shunting device converts the server serial number and the server network card ring number of the corresponding service into binary numbers to be filled into the SMAC or the DMAC, and finally converts the SMAC and the DMAC into 16-system MAC addresses. The information bit number occupied by the server serial number of different services and the information bit number occupied by the server network card ring number are not completely the same. The SMAC and DMAC have 48 bits, so that the information bit number occupied by a single service does not exceed 48 bits.

Fig. 2 is a diagram of a MAC address encoding.

Referring to fig. 2, the MAC address code is composed of SMAC and DMAC, the DMAC carries the computing unit information of services 8 to 5, and the SMAC address carries the computing unit information of services 4 to 1. And the computing unit information corresponding to each service comprises server serial number information and network card ring number information. For example, as shown in fig. 2, the server serial number of the service 8 occupies 47 th to 41 th bits of the DMAC, and the network card ring number occupies 40 th to 36 th bits of the DMAC; the server serial number of the service 6 occupies 21 st to 17 th bits of the DMAC, and the network card ring number occupies 16 th to 12 th bits of the DMAC; the server serial number of the service 3 occupies the 38 th to 29 th bits of the SMAC, and the network card ring number occupies the 28 th to 24 th bits of the SMAC; the server serial number of the service 1 occupies 11 th to 5 th bits of the SMAC, and the network card ring number occupies 4 th to 0 th bits of the SMAC.

The above occupying mode is only an example, and those skilled in the art can allocate MAC address resources and occupy the position and length of the MAC address code by the service according to each service requirement, which is not limited in the present disclosure.

In the embodiment shown in fig. 2, when one service packet only needs to be processed by the service 3, the primary offloading device 12 identifies the server serial number of the service 3 at bits 38 to 29 of the SMAC, and identifies the server target CPU core number of the service 3 at bits 28 to 24. If the serial number of the server that needs to receive the packet in the service 3 is 2 and the core number of the target CPU is 3, the SMAC address output by the primary offloading device 12 is 0000.4300.0000, and the DMAC address is 0000.0000.0000. And the second-stage shunting device 13 shunts the service message to the 2 nd server output port corresponding to the service 3 according to the MAC address code.

Referring to fig. 3, a shunt device testing method 300 may include:

step S1, acquiring the number of servers corresponding to each service in the services corresponding to the distribution equipment to be tested;

step S2, generating a piece of flow information according to the number of servers corresponding to each service, wherein the flow information includes m test messages, in the MAC address code of the ith test message, the server identification value k corresponding to the jth service is the difference between i and the sum of the numbers of servers corresponding to the previous j-1 services, the server identification values corresponding to other services are all first preset values, i is greater than 0 and less than or equal to m, j is greater than 0, and m is equal to the sum of the numbers of servers corresponding to all the services;

step S3, sending the flow information to the to-be-tested flow distribution equipment;

step S4, determining whether the distribution function and the copy function of the distribution device to be tested are normal according to the number of the feedback information at the output port of the server connected to the distribution device to be tested.

The steps of the split-flow device testing method 100 are described in detail below.

In step S1, the number of servers corresponding to each service in the services corresponding to the distribution device to be tested is obtained.

In this embodiment of the present disclosure, the testing device 15 may be connected to the first shunting device 12, read a setting scheme of an information bit occupied by each service by the first shunting device 12, determine a server identification number of a message MAC address corresponding to each service, and further determine the number of servers corresponding to the service according to a scale (for example, a 16 scale) of the message. In other embodiments, the number of servers corresponding to each service may also be determined manually and input into the testing device 15.

In step S2, a piece of traffic information is generated according to the number of servers corresponding to each service, where the traffic information includes m test packets, in the MAC address code of the ith test packet, the server identification value k corresponding to the jth service is the difference between i and the sum of the numbers of servers corresponding to the first j-1 services, the server identification values corresponding to other services are all the first preset values, i is greater than 0 and less than or equal to m, j is greater than 0, and m is equal to the sum of the numbers of servers corresponding to all the services.

In the embodiment of the present disclosure, each test packet relates to all services, and at the same time, the test packet included in one flow covers all the server output ports 131 of the secondary shunting device 13, so that the replication capability and the shunting capability of the secondary shunting device 13 can be simultaneously tested by using one test packet, and the shunting capability of the secondary shunting device 13 to all the server output ports can be tested by using m test packets.

In order to perform the performance and specification test in a comprehensive manner, the embodiment of the present disclosure sets the server identification value of the MAC address code of the multiple test packets in each service to be increased from 0 to the specification size. Therefore, in the embodiment of the present disclosure, the MAC address code of the test packet is set according to the service order and the server serial number, and in the MAC address code of the ith test packet, the server identifier k corresponding to the jth service is set to be the difference between i and the sum of the numbers of servers corresponding to all previous services.

Taking the MAC address code space occupying scheme shown in fig. 2 as an example, if the server identification value and the network card ring identification value of the service 7 computing unit occupy 35 th-27 th bits and 26 th-22 th bits of DMAC, respectively, the server identification value and the network card ring identification value of the service 5 computing unit occupy 11 th-5 th bits and 4 th-0 th bits of DMAC, respectively, the server identification value and the ring identification value of the service 4 computing unit occupy 47 th-44 th bits and 43 th-39 th bits of SMAC, respectively, and the server identification value and the network card ring identification value of the service 2 computing unit occupy 23 th-17 th bits and 16 th-12 th bits of SMAC, respectively.

In the embodiment of the present disclosure, the network card ring identifier value corresponding to each service is a second preset value, which may be set in the MAC address code of each test packet.

In other embodiments, because the splitter switch (the second splitter device 13) does not care about the network card ring number, but leaves enough bits for the corresponding network card ring number, it is possible to perform the test of different numbers of bits of the network card ring number for each group of traffic. For example, the network card ring number identification bit (40 th to 36 th bits) of service 1 occupies 5 bits, so the network card ring number scheme of the test message corresponding to service 1 may set the nth bit as 1 according to the sequence of the messages, for example, the network card ring number identification value of the first test message occupies 0 bit (i.e., 0), the network card ring number flag value of the second test message occupies 1 bit (i.e., 1), and so on, the network card ring number flag value of the sixth test message occupies 5 bits (i.e., 31), thereby testing the influence of different network card ring numbers on the device shunting.

That is, the network card ring identification number of the message MAC address code corresponding to each service may be obtained and set in the MAC address code of the i-th test message, and the number n of bits occupied by the network card ring identification value corresponding to the j-th service is the remainder of the ratio of the server identification value k to the network card ring identification number of bits corresponding to the j-th service.

When the first preset value and the second preset value are both set to be 1 (that is, the test message is designated to be copied to the first CPU core of the first server of the non-target service for processing), the initial MAC address code of the test message for the service 8 may be set to 1080-; by analogy, the initial MAC address of the test packet for the service 7 is encoded as 1080-; the initial MAC address coding of the test packet for the service 6 is 1080-; the initial MAC address coding of the test packet for service 5 is 1080-; the initial MAC address coding of the test packet for service 4 is 1080-; the initial MAC address coding of the test packet for service 4 is 1080-; the initial MAC address coding of the test packet for service 3 is 1080-; the initial MAC address encoding of the test packet for service 1 is 1080-. Through the design of the test flow, when each group of services is tested, the corresponding service group meets the maximum corresponding server identification value, and each server has the corresponding service flow, and the services can copy one flow for other service groups at the same time.

In step S3, the traffic information is sent to the shunting device to be tested.

In this step, the test equipment 15 directly sends the traffic information to the second splitter equipment 13.

In step S4, it is determined whether the shunting function and the copy function of the to-be-tested shunting device are normal according to the number of the feedback information at the output port of the server to which the to-be-tested shunting device is connected.

When a server output port receives a service message and forwards the service message to a corresponding server, the server output port generates a feedback message to record the forwarding. Therefore, whether the shunting device under test is normal is determined in step S4 by checking the number of the returned feedback information of each server output port.

Fig. 4 is a sub-flowchart of step S4 in the embodiment of the present disclosure.

Referring to fig. 4, step S4 may include:

step S41, setting j equal to 1;

step S42, judging whether the number of feedback information of the output port of the server with the sequence number of the jth service being the first preset value is equal to m-Nj +1 to obtain a first judgment result, wherein Nj is the number of servers corresponding to the jth service;

step S43, determining whether the number of feedback information at the output ports of other servers of the jth service is equal to 1 to obtain a second determination result;

step S44, when the first judgment result and the second judgment result corresponding to the jth service are both yes, the step S45 is executed, otherwise, the step S48 is executed to judge that the shunting function and the copying function of the shunting equipment to be tested are abnormal;

step S45, determining whether j is the maximum value of the service number, if not, proceeding to step S46 to make j equal to j +1, and returning to step S42; if yes, go to step S47;

and step S47, judging that the shunting function and the copying function of the shunting equipment to be tested are normal.

By checking the quantity of the feedback information at the output port of each server, the test result can be rapidly and comprehensively output, and the test accuracy is effectively improved.

The embodiment of the disclosure can ensure that the test message is copied among the services while testing each service to normally shunt in the maximum interface range by carrying out flow design according to the services, and the test method can ensure that the specification test is carried out while the test shunt switch shunts based on the MAC address code of the appointed computing unit, simplifies the test method and improves the efficiency.

In summary, in the present network, when the MAC address code based on the designated computing unit is used to pass through the shunting switch, the first-stage shunting device performs the related MAC address code, and then the shunting switch performs the shunting, and the same traffic may have corresponding MAC address codes in different service units, so that the shunting needs to be performed in the same service range according to the MAC address code of the same service unit, and the same traffic replication relationship exists between different service ranges. In the test process, the flow setting and the design of the test case are carried out according to the methods of the same service shunting and different service copying, so that the test process can be greatly simplified. The identification of a service unit consists of a server number and a network card ring number, the flow distribution switch only needs to distribute flow according to the server number, and all the flow can be divided into 8 different services according to MAC address codes, so that one flow can be designed to simultaneously meet the coding requirements of the 8 services when the flow design is tested. In addition, in order to perform performance and specification tests, the number of the server requiring the MAC address coding of the equipment flow in each service is increased from 0 to the specification size. Taking fig. 2 as an example, if the server number and the network card ring number identification number of the service 7 calculation unit are 35-27 bits and 26-22 bits, respectively, the server number and the network card ring number identification number of the service 5 calculation unit are 11-5 bits and 4-0 bits, respectively, the server number and the ring number identification number of the service 4 calculation unit are 47-44 bits, and the server number and the network card ring number identification number of the service 2 calculation unit are 23-17 bits and 16-12 bits, respectively. The MAC address coding for the traffic of the eighth service can be designed as 0210-; by analogy, the MAC address of the MAC for the traffic of the seventh service is coded as 0210-; the MAC address of the MAC for the traffic of the sixth service is encoded as 0210-; the MAC address of the MAC for the traffic of the fifth service is encoded as 0210-; the MAC address code of the MAC for the flow of the fourth service is 0210-; the MAC address code of the MAC for the traffic of the third service is 0210-; the MAC address code of the MAC for the traffic of the second service is 0210-; the MAC address of the MAC for the traffic of the first service is encoded as 0210-. Through the design of the test flow, when each group of services is tested, the corresponding service group meets the maximum corresponding server number and each server has the corresponding service flow, and the services can copy one flow for other service groups at the same time. In addition, since the splitter switch does not care about the network card ring number, but leaves enough bits for the corresponding network card ring number, it is possible to test different numbers of bits of the network card ring number for each group of traffic flows, but it is not necessary to test all possible network card ring numbers. For example, the identifier bits (40 th to 36 th) of the first network card ring number occupy 5 bits, so that 6 traffic corresponding to the first service can be designed, the first network card ring number is 0 bit (i.e., 0), the second network card ring number is 1 bit (i.e., 1), and so on, the 6 th network card ring number is 5 bits (i.e., 31). Therefore, the influence of different network card ring numbers on the equipment shunting can be tested. Meanwhile, when a test case is designed, in order to ensure that each flow of each group of services has an output interface, the number of the corresponding output interfaces is required to be the same as the incremental number of the corresponding server identification bits when the corresponding services are tested, and the output interfaces corresponding to other services can be set by self. The testing method can ensure that the specification test is carried out while the test shunting switch shunts based on the MAC address code of the appointed computing unit, simplifies the testing method and improves the efficiency.
