摘要
针对目前油田网络现状,结合未来信息化建设需求和网络技术发展趋势,通过分析比较主流的MSTP、RPR、OTN光承载网技术的优缺点,设计了基于OTN光承载网的多业务IP数据网络,形成了核心层、汇聚层、接入层三层网络结构,骨干汇聚节点通过双归属上联到冗余双核心节点;同时,骨干网传输能力从2.5G提升到10G,并具备平滑升级到40G、100G的能力。通过全新的路由和安全机制设计,提升网络整体性能,提高网络的可管理性,为油田信息化建设提供高速稳定可靠的网络环境。
Aiming at the status of Oilfield Network, combined with the future development of information construc- tion and network technology trends, by analyzing and comparing the advantages and disadvantages of MSTP, RPR, OTN technology, a muhiservice IP data network is designed based on OTN, a three-layer network structure is formed, which includes a core layer, a convergence layer and a access layer. The backbone nodes are linked to a dual-homed redundant dual-core node. The backbone transmission capacity is upgraded from 2.5G to 10G, and can be upgraded to 40G or 100G smoothly. With the new routing and security mechanisms, it can improve the overall performance and manageability of the network.
