The scope of this standard is to define services, operating at the network and transport layers, in support of wireless connectivity among vehicle-based devices, and between fixed roadside devices and vehicle-based devices using the 5.9 GHz DSRC/WAVE mode. WAVE networking services represents layers 3 and 4 of the OSI communications stack. The purpose of this standard is to provide addressing and routing services within a WAVE system, enabling multiple stacks of upper layers above WAVE networking services and multiple lower layers beneath WAVE networking services. Upper layer support includes in-vehicle applications offering safety and convenience to their users. New IEEE Standard - Superseded. WAVE Networking Services provides services to WAVE devices and systems. It represents roughly layers 3 and 4 of the OSI model and the IP, UDP, and TCP elements of the Internet model. The services provided include management and data services within WAVE devices.
