Disclosed herein are an apparatus and method for collecting vehicle diagnostic information. The apparatus for collecting vehicle diagnostic information includes a conversion unit and an optical multiplexing unit. The conversion unit receives a plurality of frames complying with respective different protocols from a plurality of networks for vehicles, which collects vehicle diagnostic information, in electric signal form, and converts the plurality of frames into a plurality of optical signals having respective different wavelengths based on the wavelengths previously assigned to the respective protocols. The optical multiplexing unit generates a wavelength division multiplexed signal by performing wavelength division multiplexing (WDM) on the plurality of optical signals, and transmits the wavelength division multiplexed signal via an optical cable.

In the method for expanding an address for an Internet protocol in an Internet edge router and the record medium capable of being read through a computer having a record of a program to realize the inventive method, an address expanding system of IPv4 used by incorporating public network connection information in an IPv4 address is utilized, thereby, all services of the existing IPv4 can be accepted and an enlargement to a new service can be valid. That is, in such Internet edge router, the inventive method comprises the steps of defining public network connection information in an option class of an Internet protocol message; b) constructing a security & authentication (SA) module and an SA hierarchical protocol in a service terminal protocol in order to provide IP address information and a user authentication from a server having information of the existing public network subscribers by using the public network connection information, and constructing a connection information processing part to process the public network connection information; and c) receiving a message from a network interface and processing it, in the connection information processing part, whereby being applied to an Internet service system.

A method of generating a flow label of an Internet Protocol version 6 (IPv6) is provided. A terminal generates a flow label to have four tuple information selected from five tuple information according to the provided method when the terminal creates a header. A network device classifies flows based on the four tuple information in the flow label generated according to the provided method. Since the flow label is generated to include only selected information and the network device analyzes less amount of information to classify the flows, the processing overhead is reduced. Also, since the terminal generates the flow label with selected essential information to classify the flows, the network device can finely classify the flows. Therefore, the differentiated service can be provided.

Provided are a system and method for informing a vehicle accident using a telematics device. In an emergency, such as vehicle collision, etc., the system and method propagate information on the accident to vehicles around the accident scene, thereby informing the vehicles of traffic congestion. Since the vehicles continuously inform the same to vehicles behind through ad-hoc communication, a vehicle guided by a telematics device can recognize the traffic congestion ahead, re-search for a path, and thereby make a detour. Therefore, although vehicles behind the accident scene cannot see the occurrence of the accident on a foggy highway, etc., the risk of a chain-reaction crash is reduced. In addition, it is possible to avoid traffic congestion due to an accident in downtown.
