Analysis Of Integration Of Ipv6 And Plc-plc, Ipv6, The European Union - Electrical Industry

First, the European Union to promote

Recently, the news: The European Commission decided to open up Europe's power line broadband Internet market.

European Commission to the European Union Member States more expensive network environment, the recent decision to open up Power Line Communication ( PLC ) Access methods to provide enterprises and the general public more easily available broadband Internet environment. According to the definition of the European Commission, PLC (PowerLineCommunication) is a method of broadband technology, the use of general transfer current power line as a medium to transmit voice, data or visual images. So long as there is Power supply Place, even located in different countries, but also capable of networking. The technology for the EU to solve the problem of varying national broadband help enormously.

According to European Commission statistics, the EU Member States are currently 200 000 000 wiring the schools, families and businesses, the European Commission that industrial cum-business Department, PLC as the access network will enable broadband market more free competition, especially public utilities control the power supply also have the opportunity to enter the broadband market. Therefore, the Commission will further develop the provisions of PLC to establish a clear and balanced market environment, market mechanism, so that existing and new competitors entering the market can provide better services.

In addition, since 2001, more than 40 countries worldwide to 100 PLC networking of pilot projects to ensure that the PLC technology and commercial feasibility. Europe's experiment focused on Germany, Austria, Spain and other countries. European Commission believes that Europe will show a power-line network of the future trend of steady growth (Figure 1), and within two years of 5% to 10% of households online coverage. Figure 1 shows in Europe on the use of PLC estimated the impact of broadband access.

2, IPv6, and the feasibility of PLC integration

Recent years, several important areas of communications technology has made great progress, including IPv6, QoS, PLC, broadband, wireless and other technologies. IPv6 has matured now, the market almost every day new applications appear. PLC technology has high bandwidth with and Other Broadband technologies such as Cable, DSL and other comparable advantage.

For the expansion of power line communication market is currently a hot research community focused on the power line access and the integration of IPv6.

First of all, IPv6 router and host range of automatic configuration mechanism, it is possible online plug and play; Second, IPv6 as a new agreement will enable more efficient deployment of power line communication network; Third, IPv6 The address space is virtually unlimited, on-line in large-scale PLC, a transparent end to end connectivity, and provide new applications and services. View of the above three points, on the integration of IPv6 with the power line communication research has become the target of public criticism. For example, the European Union to develop a joint venture called "6POWER" strategic plan to study in the power line to run the possibility of IPv6 and related protocols.

PLC itself is not even an application (in fact it is a switching technology), it still has the potential to cover a wide range of areas, which would be due in the integration of IPv6 and PLC. We have reason to believe, PLC is that we have been struggling to find the "IPv6 killer application."

, Of course, several important areas of communications technology has made great progress, IPv6, QoS, PLC, broadband, wireless and other technologies have become mature in the market, new applications continue to occur, the PLC technology has high bandwidth with and other broadband technologies, such as Cable, DSL and other advantages and fusion applications. However, IPV6, and PLC integration is not easy. But this fusion of two technologies allow full play to their potential, especially in the advanced QoS and multicast network conditions, and in NeighborDiscovery or automatic configuration, the same low level of agreement to better play to their potential.

Third, the existing state of IPV6 and PLC integration

1. The user's IP address fast-growing demand for

The next few years, several support services, equipment, PLC will appear in ordinary families. These devices will cover the personal computer and information equipment, to promote "smart appliances" of the birth, including refrigerators, air conditioners and digital cameras. To fully use these devices, it will need to assign an IP address of their respective. Therefore, intelligent home appliances and other equipment to really start and implementation, but also must overcome the following problems: most notably the lack of IPv4 address space.

End of the connection due to the need, so some of the equipment can not use the personal address space, this and the current status of IPv4 same area. PLC will accelerate service providers and network operators, the evolution from IPv4 to IPv6 speed, because people will gradually realize that, if the IP address resources become exhausted, the user will not be able to enjoy more and better services.

2. Most devices support the PLC will be used in a family environment, one of the requirements of such environment is the product must be easy to install, use and maintenance. As the user's expectations of the product to achieve "plug and play", so it becomes automatic configuration feature is extremely important, and this is one of the characteristics of IPv6 than IPv4.

3. Expected in the future there will be a large number of services and applications are used in the PLC network, such as VoIP phones, network games, Email conversion tool, download music files, many meetings, high-resolution video services. These services are bandwidth, latency and data loss rate and so have different requirements, but they must share the same network. In addition, despite the services and management by the service providers and network operators, many times to install the client have to be at home by the individual user. Clearly, there needs complex and powerful system for QoS and CoS. Some of the equipment used IPv6 system and has been used for the core IP network layer, but this application is not enough close to the user. This is another reason to accelerate the process of IPv6.

4. Multicast feature has long been a part of IP, although it has never been as a business ISP service to provide. In fact, despite the now widely used in many Internet access technologies such as dial-up, DSL and so do not use multicast (point to point transmission as it is), but the ISP multicast technology can help get the bandwidth and cost savings. With the existing content delivery networks and multimedia Internet services to increase the effectiveness of such cost savings will be significant. Practical application in the PLC, in order to improve bandwidth utilization of multimedia services, multicast technology is a very important part. Even if the PLC itself is not a
