Abstract

The invention discloses an SDH (Synchronous Digital Hierarchy) multi-domain comprehensive test device and a test method thereof, mainly solving the problem that single test equipment tests the network performance of an ATM (Asynchronous Transfer Mode) network transmitting in an SDH mode or an IP (Internet Protocol) packet network packed by adopting an HDLC (High level Data Link Control) protocol.The SDH multi-domain comprehensive test device mainly comprises a test data processor, an SDH processor and a microcomputer control system. The test method comprises the following steps of: (1) initializing the working mode of the SDH multi-domain comprehensive test device; (2) generating test information cells or packets of the corresponding working mode by the test data processor, mapping into an SDH frame and sending to a tested network element by the SDH processor; (3) extracting the test information cells or the packets from the loopback SDH frame by the SDH processor; (4) processing thereceived test information cells or packets by the test data processor; and (5) analyzing and displaying a test result by the microcomputer control system. The invention can not only test a single-mode or multi-mode multi-rate SDH network, but also realize that the single equipment tests the network performance of the ATM network and the packet network, and has easy and convenient operation and high cost performance.

Description

technical field [0001] The invention belongs to the technical field of network testing, and mainly relates to SDH transmission technology in optical fiber communication, in particular to a comprehensive testing device and testing method for SDH multi-domain performance and indexes. Background technique [0002] With the rapid development of the global broadband backbone network, access network and customer premises network, the network provides users with more and more broadband services, all of which are based on Internet Optical network SDH / SONET (Synchronous Digital Hierarchy / Synchronous Optical Network) optical fiber network transmission to the user's location. [0003] Synchronous Digital Hierarchy (SDH) is a comprehensive information transmission network that integrates multiplexing, transmission and switching, and is operated by a unified network management system. It is evolved from the Synchronous Optical Network (SONET) proposed by Bell Institute of Communications ...
