【摘要】：全业务发展是当今世界主流电信运营商的业务发展趋势之一。全业务运营是运营商发展的重要突破点。 当前全国各地LTE试验网(Long Term Evolution,移动通信技术的长期演进)正在如火如荼建设中,2014年开始将是LTE网络建设和发展的黄金期,各运营商将不遗余力地投入到LTE网络的建设中,为4G(the4Generation mobile communication technology,第四代移动通信技术)时代的通信市场竞争打下扎实的基础。2011年开始的FTTH(Fiber To The Home,光纤到户)建设更是将我国的宽带速率提上了新的台阶。随着互联网业务需求爆炸式增长,无论是传统的有线宽带还是移动互联网,数据业务发展非常迅速,新建移动回传网络及大幅扩容的IP城域网的承载对现有光缆纤芯资源需求量猛增。 传输网络是运营商重要的基础网络之一,建设规模和网络质量的好坏直接影响整个企业的业务发展。传输网作为基础网络,不仅有大容量、高灵活性、高可靠性以及高质量传输的要求,还要有较好地支持IP业务传输的要求。因此在网络发展的关键时期,MSTP(Multi-Service Transfer Platform,基于SDH的多业务传送平台)、OTN(OpticalTransportNetwork,光传送网)以及IPRAN网络(IP化无线接入网)如何部署也成为各大运营商的课题。 本文通过对主流城域传输技术SDH/MSTP、PTN(PTN Packet Transport Network,分组传送网)、IPRAN及DWDM(密集波分)、OTN等的比较,结合某运营商城域网现状的调研、业务需求的预测及经济性评价,重点阐述了面向全业务运营背景下,如何根据当前网络现状来制定适合本地区的传输网络规划。 本文总结了OTN网络的建设思路及经验。本文从新技术选定、节点选定、系统速率选定等方面介绍了OTN网络的建设思路。城域OTN网络首先部署骨干层及汇聚层,在骨干层与汇聚层重合的节点,选用电交叉子架合一的方式部署,可实现骨干层对汇聚层业务的灵活调度,节约成本。网络建设与IP网规划紧密结合的同时,还需要考虑精确投资、投资管控。综合考虑现有光缆、管道的资源状况,对传输网资源进行合理利用,使投资效益最大化。结合目前的光缆纤芯资源及施工难度、建设工期等综合因素,考虑目前市区及郊县城区具备光缆资源或新建光缆条件的区域内,短距离10GE业务采用裸纤承载,较长距离10GE业务可采用OTN系统承载,对于GE业务则尽量采用OTN承载。随着路由器100G端口的应用推广,城域OTN网络业务面临100G系统的建设。本文从技术、运维、成本等角度对40G/100G混传网络的可行性进行了分析。 本文总结了某运营商的IPRAN网络建设经验。本文从综合业务承载能力、可靠性与可扩展性、成本、网络维护等角度分析了IPRAN的4种承载技术,提出L2VPN(2层虚拟专用网络)+L3VPN(3层虚拟专用网络)在移动回传网络应用。IP RAN网络建设初期首先考虑与移动专业的需求紧密衔接,配合LTE建设,加大IPRAN网络建设范围,确保LTE基站业务端到端质量传输。明确网络发展思路和方向,通过IP转型架构建设统一的综合业务承载网。
[Abstract]:Full-service development is one of the business development trends of the mainstream telecom operators in the world.
At present, the LTE test network (Long Term Evolution, the long-term evolution of mobile communication technology) is being built in full swing. 2014 will be a golden period for the construction and development of LTE network. All operators will spare no effort to invest in the construction of LTE network, for 4G (the4Generation mobile communication technology, the fourth generation of mobile) Communication technology) the communication market competition in the era has laid a solid foundation for the FTTH (Fiber To The Home, fiber to the household) construction which has brought the broadband rate of our country to a new step. With the explosive growth of the Internet business demand, the development of data business is very rapid, whether it is the traditional cable broadband or the mobile Internet. The new mobile backhaul network and the large capacity expansion of the IP metropolitan area network have increased the demand for core resources of the existing fiber optic cable.
The transmission network is one of the important basic networks of the operators. The scale of construction and the quality of the network directly affect the business development of the whole enterprise. As a basic network, the transmission network not only has the requirements of large capacity, high flexibility, high reliability and high quality transmission, but also has a good support for the requirements of IP service transmission. The key period of the exhibition, MSTP (Multi-Service Transfer Platform, SDH based multi service transport platform), OTN (OpticalTransportNetwork, optical transmission network) and IPRAN network (IP wireless access network) how to deploy also become the major operators of the topic.
This paper compares the mainstream metropolitan area transmission technology SDH/MSTP, PTN (PTN Packet Transport Network, packet transmission network), IPRAN and DWDM (dense wave division), OTN and so on. It combines the current situation of a business city domain network, the prediction of business requirements and the economic evaluation. It focuses on how the current network is present under the background of the full business operation. Form a transmission network planning suitable for the local area.
This paper summarizes the idea and experience of the construction of OTN network. This paper introduces the construction ideas of OTN network from the aspects of the selection of new technology, the selection of nodes, the selection of system rate and so on. The city domain OTN network first deploys the backbone and aggregation layer, the joint of the backbone layer and the convergence layer, and selects the electric cross sub frame to be deployed in one way, and the backbone layer can be realized. At the same time, the network construction and the IP network planning are closely integrated, while the accurate investment and investment control are also needed to consider the existing optical cable, the resource status of the pipeline, the rational utilization of the transmission network resources, the maximum investment benefit, and the construction difficulty of the fiber core resources and construction. The short distance 10GE service is loaded with bare fiber, the long distance 10GE service can be loaded with OTN system and OTN bearer is adopted for the GE service. With the application and popularization of the 100G port of the routing device, the metropolitan area OTN network business face is also considered. This paper analyzes the feasibility of 40G/100G mixed transmission network from the point of view of technology, operation and maintenance, cost and so on.
This paper summarizes the IPRAN network construction experience of an operator. This paper analyzes 4 kinds of IPRAN bearing technology from the perspective of integrated service carrying capacity, reliability and scalability, cost and network maintenance, and puts forward L2VPN (2 layer virtual private network) (3 layer virtual private network) in the initial stage of the construction of.IP RAN network in the mobile return network. Considering the close connection with the demand of mobile specialty, with the construction of LTE, the scope of IPRAN network construction will be increased to ensure the end to end quality transmission of LTE base station business. The idea and direction of network development are clearly defined, and a unified integrated service bearing network is built through the IP transformation framework.
