Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS). The present document is part 3 of a multi-part deliverable. Full details of the entire seri

13、es can be found in part 1 i.13. Introduction The present document specifies the network architecture for communication-based Intelligent Transport Systems (ITS) using different ITS access technologies, such as ITS-G5. The network architecture provides - in combination with the description of scenari

14、os - a basis for the technical specification of the network and transport protocols, in particular for GeoNetworking and its related protocols. The present document first introduces a generic, high-level system view of the network architecture and defines four basic deployment scenarios. Based on th

15、e system view, it identifies and describes the main network components and specifies network reference points among them. Central component of the architecture is the ITS station. For this component, an overview of its protocol architecture is given and different options of using the GeoNetworking p

16、rotocol in combination with transport protocols and protocols of the IP suite are described. Finally, the present document defines frameworks for different aspects of networking and data transport, such as ad hoc communication, addressing, resource management and data congestion control, integration

17、 with protocols of the IP suite and others. The network architecture is based on the ITS architecture specified in 1 and represents the networking viewpoint of the overall architecture. Sources of input for the present document are i.1, i.2 and i.3. ETSI ETSI TS 102 636-3 V1.1.1 (2010-03)51 Scope Th

18、e present document specifies the network architecture for communication-based Intelligent Transport Systems (ITS). The network architecture is focused on, but not limited to, vehicular communication. The architecture enables a wide range of ITS applications for road safety, traffic efficiency as wel

19、l as for infotainment and business. The present document defines the framework for network and data transport protocols that provide data exchange among ITS stations. A particular aspect is the GeoNetworking protocol that provides ad hoc and multi-hop communication over short-range wireless technolo

35、router: IPv6 router that provides access to other networks, such as to the ITS access network NOTE: The definition is taken from i.5 and adapted to the ITS network architecture. ETSI ETSI TS 102 636-3 V1.1.1 (2010-03)7access network gateway: router at the edge of a network that connects an ITS stati

37、es the communication services of a communication ITS services provided by road traffic management centres and backend services; ITS operational support services required to operate the ITS, such as security services. Core component of the architecture is the ITS station, which has two main roles: In

38、 its first role, the ITS station is a network node and acts as a communication source or sink. Likewise an ITS station can be a forwarder of data, e.g. in the ITS ad hoc network. In its second role, the ITS station is placed at the network edge and connect the different networks via an ITS station i

39、nternal network (see Figure 1). ITS stations shall be able to communicate via at least one of the following means (see Figure 2): a) via an ITS ad hoc network; b) via an ITS access network; c) via a public access network; d) via a private access network; e) via one of the access networks into the co

40、re network (e.g. the Internet). In addition to the networks listed above, an ITS station can also be attached to proprietary local networks of e.g. vehicle ITS sub-systems and roadside ITS sub-system as presented in 1. Typical examples are: Controller Area Network (CAN) in a vehicle ITS sub-system.

41、Legacy roadside infrastructure in a roadside ITS sub-system. However, these proprietary networks are outside the scope of the present document. ETSI ETSI TS 102 636-3 V1.1.1 (2010-03)10Figure 2: High-level network architecture 5 Deployment scenarios of the generic network architecture The ITS networ

42、k architecture can be deployed in different scenarios to adapt to specific economical and regulatory conditions and to facilitate a gradual introduction of ITS. Basically, a deployment scenario is a subset of the overall architecture (see Figure 2) created by a combination of the different network t

43、ypes. Four basic deployment scenarios can be defined. The basic deployment scenarios can further be extended to hybrid scenarios that combine two or more deployment scenarios. These combinations also include scenarios in which a network is connected to more than a single network simultaneously. Scen

44、ario A establishes an ITS ad hoc network, which can be connected via an ITS access network to the core network (e.g. the Internet) (see Figure 3). Deployment scenario B represents an ITS access network, which can be connected to the core network (e.g. the Internet) (see Figure 4). Deployment scenari

45、o C is based on a public access network, which can also provide connectivity to the core network (e.g. the Internet) (see Figure 5). Deployment scenario D uses a private access network to connect to other networks or the core network (e.g. the Internet) (see Figure 6). Figure 3: Deployment scenario

46、A: Ad hoc-centric In Figure 4, the ITS access network connects roadside ITS stations to each other and provides connectivity to a core network (e.g. the Internet). Optionally, the ITS access network can also be replaced by a public or private access network. ETSI ETSI TS 102 636-3 V1.1.1 (2010-03)11
