Resides on the L2VPN, the simulated IP address must be specified as Receiving test flows must be specified on the reflector. The destination IP and MAC addresses and the source IP address mustīe specified on the initiator, and the destination IP address for In location 2, it is an L2VPN accessing 元VPN scenario. In location 3, or the initiator resides in location 4 and the reflector Location 4, the initiator resides in location 1 and the reflector If the initiator resides in location 1 and the reflector in In locations 3 and 4 (or 4 and 3), respectively, it is an IP gateway (or 2 and 1), respectively, or the initiator and reflector reside If the initiator and reflector reside in locations 1 and 2 IP address must be configured on the L2VPN device. In location 4, it is similar to an IP gateway scenario, and the simulated Location 1, or the initiator resides in location 2 and the reflector If the initiator resides in location 3 and the reflector in

(or 3 and 2), respectively, it is a native IP scenario.

If the initiator and reflector reside in locations 2 and 3 In locations 4 and 6 (or 6 and 4), respectively, it is a native Ethernet (or 5 and 1), respectively, or the initiator and reflector reside If the initiator and reflector reside in locations 1 and 5 In the L2VPN accessing 元VPN networking shown in Figure 4-2, the initiator and reflector can reside in different locations Initiator and a reflector perform a general flow test to monitor theįorwarding performance for end-to-end services exchanged between two Layer 2: native Ethernet, L2VPN (VLL and VPLS), EVPN The time the forwarding devices process the test packet.Ī general flow test can be used in the following scenarios: The transmission time in each direction includes Latency: consists of the bidirectional delay time and jitterĬalculated based on the transmission and receipt timestamps carried Packet loss rate: percentage of discarded packets to all sent Throughput: maximum rate at which packets are sent without loss.So that NQA general flow tests can be conducted on a network on whichīoth Huawei and non-Huawei devices are deployed.Ī general flow test measures the following counters: Uses standard methods and procedures that comply with RFC 2544 If no services are deployed, testers must be Unlike general flow tests, can only be used when services have beenĭeployed on networks. An NQA general flow test hasĮnables a device to send simulated service packets to itselfīefore services are deployed on the device. Test helps the customer evaluate whether the network performance counters
