SHPE3, RR/P, MHPE1 and MHPE2 emulating a service provider network. CE is a customer device connected to MHPE1 and MHPE2, it is configured with bridge domains in different vlans. The router tester is connected to CE and SHPE3.The MHPE1 acts as DUT.The RT will act as sender and receiver.The measurement will be taken in DUT. All routers except CE is configured with OSPF/IS-IS,LDP,MPLS,BGP with EVPN address family. Jacob & Tiruveedhula Expires April 11, 2019 [Page 6] Internet-Draft EVPN-VPWS Benchmarking Methodology October 2018 All routers except CE must have IBGP configured with RR acting as route reflector. MHPE1,MHPE2,SHPE3 must be configured with "N" EVPN-VPWS instances depends up on the cases. MHPE1 and MHEPE2 must be configured with ESI per vlan or ESI on IFD. MHPE1 and MHEPE2 are running Single Active mode of EVPN-VPWS. CE is acting as bridge configured with vlans that is configured on MHPE1,MHPE2,SHPE3. Depends up on the test traffic will be flowing uni directional or bi directional depends on the topology mentioned above. The above configuration will serve as base configuration for all the test cases. 3. Test Cases The following tests are conducted to measure the packet loss during the local link and core failure in DUT with Scaled AC's. 3.1. How long it takes to switch from primary to backup during local link failure Objective: To Record the time taken to switch from primary to backup during local link failure. Topology : Topology 1 Procedure: Configure "N" AC's in SHPE3 and MHPE1,MHPE2, working in SA mode.Ensure MHPE2 is active and DUT is backup PE.Send "X" unicast packets from CE to MHPE2 AC's working in SA.Then shut the MHPE2-CE link, so that traffic from CE switches to DUT. Measurement : Measure the time taken to switch the traffic from active to backup, the traffic will flow from MHPE1 to SHPE3. Measure the time taken to switch the traffic. Jacob & Tiruveedhula Expires April 11, 2019 [Page 7] Internet-Draft EVPN-VPWS Benchmarking Methodology October 2018 Repeat these test and plot the data. The test is repeated for "N" times and the values are collected. The switching time is calculated by averaging the values obtained from "N" samples. AC's switch over from primary to backup PE in sec = (T1+T2+..Tn/N) 3.2.

Measurement : Measure the time taken to switch the traffic from active to backup, the traffic will flow from SHPE3 to MHPE1. Measure the time taken to switch the traffic. Repeat these test and plot the data. The test is repeated for "N" times and the values are collected. The switching time is calculated by averaging the values obtained from "N" samples. AC's in remote PE switches from primary to backup PE in sec due to core failure = (T1+T2+..Tn/N) 3.4. How long it takes to primary PE to regain control after the local link flap Objective: To Record the time taken by primary PE to regain control after the local PE-CE link flap. Topology : Topology 1 Procedure: Configure "N" AC's in SHPE3 and MHPE1,MHPE2, working in SA mode.Ensure MHPE2 is standby and DUT is primary PE.Send "X" unicast packets from CE to all Ac's in MHPE1(DUT).Then shut the link of MHPE1-CE,this failure will be notified to remote PE and traffic switch to backup path. Then bring up the link of MHPE1-CE.Now the traffic switches to DUT. Measurement : Measure the time taken to switch the traffic from MHPE2 to DUT, the traffic will flow from MHPE1 to SHPE3. Measure the time taken to switch the traffic. Repeat these test and plot the data. The test is repeated for "N" times and the values are collected.

Jacob & Tiruveedhula Expires April 11, 2019 [Page 9] Internet-Draft EVPN-VPWS Benchmarking Methodology October 2018 Time taken to switch back to primary(DUT) once the link is restored = (T1+T2+..Tn/N) 4. Activate/deactivate AC's 4.1. To Add M number of attachment circuits. Objective: To measure the performance of the DUT while adding M AC's on the fly. Topology : Topology 3 Procedure: Configure "N" AC's in SHPE3 and MHPE1,MHPE2, working in SA mode.Ensure MHPE2 is active and DUT is backup PE.Send "X" unicast packets from RT to SHPE3 Ac's and send "X" unicast packets from CE to MHPE1(DUT),let the DUT is the active and the MHPE2 must be standby.

DUT will be forwarding the traffic to CE and from CE to SHPE3.Then do a routing engine fail-over. Measurement : There should be 0 traffic loss which is the ideal case, No change in the DF role. DUT should not withdraw any routes.Repeat the test "N" times and plot the data.The packet loss is calculated by averaging the values obtained from "N" samples. Packet loss in sec = (T1+T2+..Tn/N) 7. SOAK Test This is measuring the performance of DUT running with scaled configuration with traffic over a peroid of time "T'". In each interval "t1" the parameters measured are CPU usage, memory usage, crashes. 7.1. To Measure the stability of the DUT with scale and traffic. Objective: To measure the stability of the DUT in a scaled environment with traffic.
