背景技术 Background technique

[0002] 信息技术已成为当今推动社会向前发展的巨大动力,信息网络在各国经济和社会的发展中占据重要地位。 [0002] Information technology has become the great power forward in today to promote social development, information networks play an important role in the development of national economy and society. 按照服务内容和范围的不同,当今信息网络可分为互联网、广播电视网和电彳目网。 According to different service content and scope of today's information network can be divided into the Internet, radio networks and electric left foot mesh.

[0003] 随着经济与社会的发展,要求当今信息网络能在任何地点、任何时间、以任何方式提供高速快捷的信息服务。 [0003] With the development of economy and society, the demands of today's information network can at any place, any time, in any way to provide high-speed and efficient information services. 而现有信息网络的原始设计思路是以一种网络来支撑一种主要服务的解耦方式,在此基础上的演进与发展难以突破原始设计思想的局限,也就无法满足网络及服务的多样性需求。 The original design idea is based on the existing information networks for network services to support a major decoupling way, the evolution and development on this basis is difficult to break through the limitations of the original design ideas, it will not be able to meet the diverse networks and services requirements. 例如互联网最初的设计思想是面向数据传输业务,它的拓扑结构是具有幂律结构的无标度网络,但是这种幂律结构拓扑导致互联网对恶意攻击的抵御十分脆弱,而且互联网不支持多种业务的接入需求,不能为多元化用户提供普适服务;电信网最初的设计思想是面向语音业务传输设计的,虽然能够提供电信级的对称话务质量,但是以电路交换为基础的两层垂直结构(信令层和物理层)及三层树状平面拓扑结构决定了其网络效率的低下,同时电信网带宽受限,导致了其无法适应宽带流媒体业务的需要。 The original design such as the Internet is for data transmission services, its topology is scale-free networks with power-law structure, but this power-law topology leads to malicious attacks against Internet fragile, but the Internet does not support multiple access business needs, do not provide universal service for the diversified user; telecommunications network was originally designed for voice transmission is thought design, even though it can provide the quality of telecommunications traffic symmetry class, but to the circuit switched based layers vertical structure (signaling and physical layer) and layer plane tree topology network determines its efficiency is low, while the telecommunications network bandwidth is limited, it can not adapt to leads broadband streaming media service. 目前,网络服务的实现方式、服务类型及终端设备都具有多样性和多变性。 Currently, Web services implementation, type of service and terminal equipment have diversity and variability. 因此,各种服务间存在兼容性差、可扩展性差、难于控制管理等难题。 Thus, the presence of poor compatibility between the various services, poor scalability, difficult to control and management problems. 为解决以上问题,近年来各国都积极开展下一代信息网络的研究工作。 To solve the above problem, in recent years, countries have actively carried out research next-generation information network. 我国也在十一五规划建议中明确提出了今后五年对信息网络技术领域的重点支持。 China is also recommended Eleventh Five-Year Plan clearly put forward the next five years focusing on the information network technology. 国家的长期发展规划将“下一代网络关键技术与服务”作为今后几十年我国信息网络技术的发展方向。 Long-term development plan of the country will be "the key to the next generation network technology and services" as the development direction of the next few decades information technology network in China.

[0004] 在这种背景下,国家973重点基础研究发展规划项目提出了一种一体化标识网络的体系结构,目标是实现服务的一体化、网络的一体化。 [0004] In this context, the National 973 Key Basic Research Development Program proposes an integrated architecture identifies the network, the goal is to achieve the integration of integration services, network. 一体化标识网络体系结构提供多元化的网络和终端接入,并具有提供普适服务的能力。 Identifying integrated network architecture provides access to a wide range of networks and terminals, and the ability to provide a universal service. 在一体化标识网络中,允许固定用户和移动终端、移动子网、自组网用户等多种移动性接入,固定用户和移动用户享有同样的个性化业务服务,实现分布式网络资源的共享和查找服务,进行语音、数据、图像等业务的传输,并提供精细粒度的服务质量,确保向用户提供一致的、普遍的业务。 In the integrated identification network, allowing fixed and mobile terminals, mobile subnets, network access from a variety of mobile users, etc., fixed and mobile users enjoy the same personalized business services, shared network of distributed resources and find services for voice, data, image transmission and other services, and provide fine-grained quality of service, to ensure a consistent, universal service to users.

[0005] 一体化标识网络的体系结构模型如图1所示,它包括“网通层”和“服务层”。 Architecture Model [0005] Integrated identifying the network shown in Figure 1, it comprises a "Netcom layer" and "Service Layer." 在一体化标识网络模型中提出了一体化标识网络标识的分离聚合映射理论,并且引入了四个虚拟子层:虚拟服务子层、虚拟连接子层、虚拟接入子层和虚拟骨干子层;分别对应了四个网络标识:服务标识SID (Service Identity)、连接标识CID (Connection Identity)、交换路由标识RID (Router Identity)、接入标识AID (Access Identity);三个解析映射:服务标识解析映射、连接标识解析映射和接入标识解析映射。 Proposed in an integrated network model identifier identifies the network in separate integrated identity mapping theory of polymerization, and the four virtual sub-layer is introduced: Service virtual sub-layer, sub-layer virtual connection, virtual sub-layer and the virtual backbone access sub-layer; respectively corresponding to the four network identifier: service identifier SID (service identity), connection identification CID (connection identity), to exchange routing identifier RID (Router identity), the access identifier AID (access identity); three resolution mapping: parsing service identifier mapping, and the connection identifier resolution mapping access identifier resolution mapping.

[0006] “网通层”包括虚拟接入子层和虚拟骨干子层,为语音和数据等业务提供一体化标识网络通信平台。 [0006] "Netcom layer" includes a virtual sub-layer and a virtual backbone access sublayer, provides network communications platform for identifying integrated voice and data services and the like. 虚拟接入子层的功能是管理各种终端和传感网络的接入;虚拟骨干子层负责位置管理和交换路由。 Function of the virtual sub-layer is to manage the access terminals and various sensor network access; virtual backbone and location management sublayer is responsible for switching and routing. 通过将终端用户所在的网络虚拟接入子层和运营者所在的网络虚拟骨干子层进行分离,保证了各种接入技术和核心网架构的相对独立性。 The end-user through the network where the virtual sub-layer access and virtual network operators where the key sub-layer separation, to ensure the relative independence of various access technologies and core network architecture. 语音和数据等业务在“网通层”中采用“转发通信”模式进行传输:在虚拟接入子层使用接入标识转发数据,在虚拟骨干子层采用内部的交换路由标识RID代替接入标识AID转发,到达通信对端的接入交换路由器后,数据包的交换路由标识RID变换为原来的接入标识AID ;虚拟接入子层负责通信终端的介入,虚拟骨干子层负责位置管理和交换路由。 And other voice and data services using the "network communication layer" in the "forward communication" transmission mode: forwarding data in a virtual sub-layer access using the access identifier used to exchange routing identifier RID instead of the inside of the access identifier AID virtual sub-layer backbone forwarding, to arrive at the communication terminal after the access switch router, switching route identifier RID transformed data packet access identifier AID of the original; Interventional virtual access sublayer is responsible for the communication terminal, virtual backbone sublayer is responsible for switching and routing, and location management. 因此,在“网通层”中我们可以实现用户的隐私性和安全性、核心网规模的可扩展性、网络的可控可管性和移动终端的可移动性。 Thus, in "Netcom layer" we can achieve privacy and security of user controllable scale core network scalability, network manageability and mobile terminal mobility.

[0007] “服务层”包括虚拟服务子层和虚拟连接子层,负责各种业务的会话、控制和管理。 [0007] "service layer" includes virtual services and virtual sub-layer session connection sub-layer is responsible for a variety of business, control and management. 虚拟服务子层引入了服务标识SID,其作用是对各种网络支持的服务进行统一的分类标识和定位。 Virtual sub-layer services introduced service identifier SID, whose role is to support a variety of network services unified classification to identify and locate. 虚拟标识解析映射将服务子层和虚拟连接子层的工作联系起来,完成服务标识与连接标识的映射,实现通信设备间的服务连接。 Virtual identity resolution mapping service sublayer and virtual sub-layer connection link, complete the mapping service marks of identity and connection to achieve service connection between the communication device. 虚拟接入子层引入了连接标识CID,作为端到端通信链路的标识。 Virtual sub-layer is introduced access connection identifier CID, identifying a communication link end. 它是普适服务模型的核心,可以很好的支持移动性、安全性,并提供一定的服务质量保证。 It is the core of universal service model, can be a good support mobility, security, and provide a certain quality of service guarantees. 连接标识解析映射,将虚拟连接子层和网通层的工作联系起来,完成一个连接标识CID到多个交换路由标识RID的映射,实现服务连接在网络上的多路径选择。 Connection identifier resolution mapping, the virtual connection sub-layer and the working layer Netcom linked to complete a connection identifier CID is mapped to a plurality of switching route identifier RID, multi-service connection path selection to the network.

[0008] 所以,在一体化标识网络中,基于虚拟服务子层定义的服务标识SID,对各种网络支持的不同服务进行统一的标识命名,以完成统一的服务调度,为在一体化标识网络上支持多种服务提供可能。 [0008] Therefore, in an integrated network identification, service-based virtual sub-layer defined service identification SID, for a variety of different services supported by the network of unified identity named to complete the unified service scheduling, to identify the network integration in support a variety of services on offer possible. 在“服务层”中,各种业务绑定不同的服务标识SID_1、SID_2、SID_3等,然后进行从服务标识到连接标识的解析、从连接标识到交换路由标识的解析,从而可以建立复式服务的服务标识和连接标识解析映射理论。 In the "service level", the various services of different service identifier binding SID_1, SID_2, SID_3 the like, and then analyzing the service identifier from a connection identifier from a connection identifier to the identifier associated routing switching, which can establish a duplex and services service marks and connected identity resolution mapping theory. 这种接入标识映射理论使得接入网和核心网分离,由接入标识提供可控可管和身份鉴别,从而保证了移动性和安全性。 Such access identifier mapping theory that the access network and the core network separation, providing a controllable and manageable authentication by an access identifier, thereby ensuring the mobility and security.
