Ip Network Reliability

IP technology has already become mainstream technology of carrier class. So it demands a higher credibility. For example, data of key path must be backed. If some section of this key path breaks down, interrupting the service based on this path. We must find the failure and switch our service to another path in split second, which is backup path. It could make clients almost doesn't aware this accident has ever happened and avoid producing heavily negative effect.This article expounded the OSI reference module, basic theory of Net Technology. OSI Reference Module stride the first step for making protocols of all layers internationalized. Full name of OSI is Open System Interconnection, because it refers to how to connect open system. This article researched protocol of Link layer, protocol of Network layer and Multi-Protocol Label Switch, creating a stability foundation.According to the most popularity flow of ASIC Design, requirements analyzing is absolutely necessarily for turn IP Network reliability Technology into ASIC. This article research several kinds of protocol, such as ETH OAM, MPLS OAM, BFD. Particularity researching to these protocols and deeply analyzing to requirements of network organizing ensured that AISC requirement and specification are right.In process of design and realizing it, I marked out the schedule absolutely basing the standard ASIC design flow. I design my design according to the standard in every sub-flow, such as Requirement Analyzing, Architecture Design, RTL coding, Logic synthesis, Formality, STA, and so on. Finally, I take out high quality netlist to foundry.IP network reliability technology realization in ASIC has some peculiarity as follows. ASIC function analyzing is reasonable based on the OAM protocol. It can fulfill every telecom company's demand. This article has a programmable theory, which could apply some specific function for processing some unknown protocol.
