example 1

[0046] Figure 5 It is a schematic diagram of networking according to the pseudowire circuit simulation test of Example 1 of the present invention, such as Figure 5 As shown, the TDM interface on the AC side of the DUT is connected to a bit error detector BERT, and the uplink port of the DUT is connected to a pseudowire circuit simulation test device 50. The pseudowire circuit simulation test device 50 mainly includes a packet receiving module 52, a data For the processing module 54 and the packet sending module 56, the test method of using the pseudowire circuit to simulate the test device 50 will be described below.

[0047] Step 1, when the TDM interface on the user side is working normally, there will be a steady stream of data streams encapsulated into pseudowire data packets, and sent from the uplink port of the DUT to the pseudowire circuit emulation testing device 50 .

[0048] Step 2: After the packet receiving module 52 intercepts the pseudowire data packet, it sen...

[0056] The processing of the pseudowire circuit emulation test device 50 will be described in detail with reference to the accompanying drawings.

[0057] First, start the program, and the user configuration interface will pop up. On this user interface, the user is required to select the network card (Net Card field) and enter the MAC address of the device under test (for example, the DUT’s Mac field, which is a required configuration). In addition, the optional configuration is to send the protocol packet LDP, and modify fields other than the MAC address (may include the MAC address of the test device), for example, the label field (such as the inner label Inner Label field and the outer label field Outer Label field) and IP address fields (eg, the IP address field for the device under test and the IP address field for the test set).

Abstract

The invention discloses a test method and a test device for pseudo wire circuit emulation. The device is connected to an upper connection port of tested equipment DUT and comprises a configuration module, an update module and a transmitting module, wherein the configuration module is used for configuring pseudo wire circuit emulation parameters, wherein the pseudo wire circuit emulation parameters comprise an address mark for indicating the DUT and an address mark of the test device; the update module is used for updating the received corresponding configuration fields in a pseudo wire data packet from the upper connection port according to the pseudo wire circuit emulation parameters, wherein the pseudo wire data packet carries the address mark of the DUT and the address mark of the test device; and the transmitting module is used for transmitting the updated pseudo wire data packet to the upper connection port. The method and the device increase the utilization rate of resources and the flexibility of a system, and improve user experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a testing method and device for pseudo wire circuit simulation. Background technique [0002] Pseudo Wire Emulation Edge to Edge (PWE3 for short) is to provide a tunnel on a packet switching network (for example, Internet Protocol IP / Multiprotocol Label Switching MPLS) in order to simulate some services (for example, Frame Relay FR , asynchronous transfer mode ATM, Ethernet Ethernet, time-division multiplexing synchronous optical network TDM SONET / synchronous digital system SDH) two-layer virtual private network (Virtual Private Network, referred to as VPN) protocol, through which the traditional network and Packet-switched networks are interconnected to share resources and expand the network. [0003] figure 1 is a schematic diagram of a pseudowire circuit emulation service according to related technologies, such as figure 1 As shown, for a TDM service (for example, an E1 type TDM c...
