Abstract

The invention discloses a layered simulation service single disk application software design method and system, which relates to the technical field of simulation service. The invention divides the simulation service single disk application software into electric port LIU layer, optical port optical module layer, SDH segment layer, SDH high layer, SDH low layer, PDHE1 layer, link PW layer and Ethernet ETH layer according to the service layer, and independently compiles the codes of each layer to realize the functions of each simulation service layer. Then, according to the service requirementsof each type of simulation service single disk, the corresponding simulation service layer combination compilation is selected to generate the application software corresponding to each type of simulation service single disk; The invention is applicable to all simulation business single disk application software development, can achieve the effect that simulation business single disk applicationsoftware using a unified platform, unified code, unified maintenance. Each simulation service layer is independent of each other and has little coupling. It can be made into a small CBB separately, which is easy to modify, maintain and use.

Description

technical field [0001] The invention relates to the technical field of simulation business, in particular to a method and system for designing layered simulation business single-disk application software. Background technique [0002] CES (Circuit Emulation Service, circuit emulation service) adopts PWE3 (Pseudo-WireEmulation Edge to Edge, edge-to-edge pseudo-wire emulation) simulation technology, and carries TDM (Time Division Multiplex, time division multiplexing) in the PWE3 header Frame format information, alarm information, signaling information and synchronization timing information of the service flow. The encapsulated PW (Pseudo Wire) message is encapsulated by the protocol and then transmitted on the PSN network through the MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching) tunnel. After arriving at the PW egress, it is decapsulated, and finally the TDM circuit switching service is rebuilt. flow. CEP (Circuit Emulation over Packet, circuit emulatio...
