Detailed Description
Embodiments of the present application are described below with reference to the accompanying drawings.
The FIB routing table entry issuing time testing system and method provided by the embodiment of the application are mainly suitable for network equipment or distributed network equipment supporting a stacking system.
Referring to fig. 1, a system for testing a routing table delivery time provided in the embodiment of the present application includes: the main Test device 11, the first auxiliary Test device 12, the second auxiliary Test device 13, the first tester port (TC) 14, and the second tester port 15, where the main Test device 11 includes a main Test board Card (Card)111 and at least one auxiliary Test board Card 112.
The First auxiliary device 12 and the second auxiliary device 13 need to support a static link aggregation and a dynamic routing Protocol, such as an Open Shortest Path First Protocol (OSPF), a Border Gateway Protocol (BGP), and the like.
The FIB routing table specifications of the first slave device 12 and the second slave device 13 are equal to or larger than the FIB routing table specification of the master device 11. The FIB routing table specification of the auxiliary test board card 112 is greater than or equal to the FIB routing table specification of the main test board card 111. Therefore, when the boards are switched, the issue failure caused by insufficient FIB routing table specification can be avoided.
Examples 1,
An embodiment of the present application provides a method for testing FIB routing table delivery time, which is applied to the foregoing system, and as shown in fig. 2, the method includes:
s101, the first auxiliary device 12 is connected to the first member port IF1 of the main board card 111 and the second member port IF2 of the auxiliary board card 112 through the first static link aggregation L1, and is configured to establish a first logical link between the first auxiliary device 12 and the main board card 111 and the auxiliary board card 112.
The adoption of static link aggregation mainly considers the following aspects: firstly, once the member ports of the static Link Aggregation are successfully physically negotiated, the logical ports of the static Link Aggregation can be successfully automatically negotiated, and a Link Aggregation Control Protocol (LACP) renegotiation Link is not performed any more, so that the time consumed correspondingly is reduced, and the time accuracy is relatively improved. And the generation of packet loss caused by issuing other non-FIB routing table items due to link switching in the test process is reduced, and zero packet loss is ensured to be generated when the logical link unchanged physical link is switched among member ports of different board cards. Thirdly, after any one of the member port IF1 and the member port IF2 is disconnected, the state of the logic port where the static links converge is always in a connected state, so that the OSPF neighbor state and the state of the software routing table entry are not affected, and the state of the routing protocol of the whole device and the state of the upper-layer software routing table are not affected when the main test board card is pulled out or inserted.
S102, the second auxiliary device 13 is connected to the third member port IF3 of the main board card 111 and the fourth member port IF4 of the auxiliary board card 112 through the second static link aggregation L2, and is configured to establish a second logical link between the second auxiliary device 13 and the main board card 111 and the auxiliary board card 112.
S103, after the upper layer software of the master device 11 has learned the upper layer software routing table, setting the first tester port 14 to send the data stream with the traffic rate S to the second tester port 15 through the first logical link and the second logical link, where the data stream covers all entries of the FIB routing table.
The aim of emphasizing that the time for upper-layer software to learn the routing table is eliminated when the time for issuing the FIB routing table is counted after the upper-layer software of the main device 11 has learned the routing table of the upper-layer software.
S104, adjusting a load balancing algorithm of static link convergence, so that the data stream is only loaded to the main test board card 111 of the main test device 11 in a static link convergence state.
And S105, when the main test board card 111 is pulled out and then is inserted into the main test equipment 11 again, counting the packet loss m of the data stream.
Since the setting in step S104 is in the static link convergence state, the data stream must be forced to flow through the board card 111, but when the board card traffic is switched to the board card 111 just after loading, the FIB routing table entry of the board card 111 is not issued immediately, and packet loss occurs. Only after the FIB routing table is issued from the upper-layer software to the chip of the main test board 111 again, the data stream can be normally forwarded from the main test board 111, and packet loss does not occur. Therefore, the accurate packet loss time can be obtained by quoting the packet loss number and the packet sending rate.
And S106, calculating the issuing time t of the FIB routing table according to the t-S/m.
According to the method for testing the issuing time of the FIB routing table, the main test board card and the auxiliary test board card are configured to be static links for aggregation, and the data stream only flows through the main test board card in the static link aggregation state, so that when the FIB routing table is issued just after the main test board card is inserted into the main test equipment and loaded, packet loss of the data stream is generated because the issuing of the FIB routing table is not completed, the packet loss can not stop until the issuing of the FIB routing table is completed, the packet loss time is just the issuing time of the FIB routing table, and accordingly accurate testing of the issuing time of the FIB routing table can be achieved.
According to the method for testing the issuing time of the FIB routing table, two board cards with the same specification are adopted, static links are constructed across two ports of the cards to be converged, the purpose is to ensure that the learned upper-layer software routing table does not have routing oscillation, and the pure time of issuing chips by the existing upper-layer software routing table is obtained by switching the states of the board cards. Meanwhile, after the learning time of the upper routing table is eliminated, the pure FIB routing table entry issuing time with full specification is constructed through the plugging and unplugging actions of the two board cards.
Examples 2,
The embodiment of the present application provides another FIB routing table issue time testing method, which is applied to the foregoing system, and as shown in fig. 3, the method includes:
s201, confirming the FIB routing table specification.
The FIB routing table specification is usually a specification of each board or each test equipment in the system, and the specification number is n (unit k), for example.
S202, a first static link aggregation and a second static link aggregation in the system are created.
This step is the same as S101 and S102, and will not be described again.
S203, the main device and the first auxiliary device build a routing neighbor through the convergence of the first static link, and the main device and the second auxiliary device build a routing neighbor through the convergence of the second static link.
S204, upper-layer software of the main testing device learns the FIB routing table according to the routing neighbors and confirms that the main testing board card and the auxiliary testing board card can support issuing the FIB routing table with the maximum specification (n in the embodiment of the application) in a stable state.
This step corresponds to S103.
S205, the first tester port is set to send data flow with the flow rate of S (per pps) to the second tester port through the first logic link and the second logic link.
This step corresponds to S104, where the data stream covers all entries of the FIB routing table obtained through the routing neighbor learning in step 204, that is, it is determined that the master device can normally forward according to all entries in the FIB routing table.
And S206, setting a link aggregation traffic load mode of the first auxiliary device and message characteristics sent by the first tester port, so that data streams from the outgoing direction of the first logic link of the first tester port all flow through the main test board card through the first member port in an aggregation state, and confirming that the data streams between the first tester port and the second tester port are normally received and sent without packet loss in the middle.
And S207, when the main test board card is pulled out, confirming that all data streams sent from the first tester port to the second tester port flow through the auxiliary test board card, emptying the receiving and sending packet statistics of the first tester port and the second tester port after the flow is stable, and starting packet loss statistics.
And S208, when the main test board card is inserted, waiting for the successful software loading of the main test board card, and enabling each member port of the main test board card to be normally connected, wherein at the moment, the data stream flows through the main test board card again according to the setting of the S206.
Because the setting of step S206 is in the static link convergence state, the forced data stream must flow through the main board card, but when the loading is just successful, the FIB routing table is not yet completely issued, and packet loss occurs. Only after the member ports of the main test board card are normally connected, the upper-layer software of the main test device starts to issue an FIB routing table to the chip of the main test board card, and records the total packet loss amount in the link switching process as m after the data stream is consistent from the initial packet loss to the final all receiving and sending.
This step corresponds to S105.
And S209, calculating the issuing time t of the FIB routing table of the main test board card according to the t-S/m.
This step corresponds to S106.
Compared with the method described in fig. 2, the FIB routing table issuance time testing method provided in the embodiment of the present application adds many steps for confirming the correct operation of each board card and testing device, and also realizes the accurate testing of the FIB routing table issuance time.
