When connecting to the Internet using an optical line from home, data communication can be performed by connecting to the contracted ISP with a authentication method called "PPPoE".
However, PPPoE connection has a major drawback.That is, the communication speed may decrease or a large delay may occur during congestion.
When connecting to the Internet with a PPPoE connection using FLET'S Hikari, connect to the "Network Ending Equipment" provided in the "Next Generation Network (NGN)" in NTT East and West, which is FLET'S Hikari Network, and the net ending device.It will be connected to ISP via, and you will be able to access the Internet through user authentication.
In this case, if the number of users, the amount of communication, or increased, the load on the net ending device may increase, reducing the communication speed or a large delay.
The connection method based on IPv6 IPoe, such as "V6 Plus," was prepared to eliminate such PPPoE defects.The V6 Plus is an Internet connection service for NTT East and West "FLET'S Hikari" provided by Japan Network Einbller Co., Ltd. (JPNE), as introduced at the beginning.
v6プラスは、JPNEが提供するNTT東西の「フレッツ光」向けIPv4/IPv6インターネット接続サービスで、PPPoE接続の欠点を解消した接続方式(JPNEのサイトより抜粋)In V6 Plus, first connect to NTT East and West NGN with IPv6.However, IPv4 and IPv6 are not compatible and cannot access the IPv4 network as they are.Therefore, in the V6 Plus, the method called "IPv4 Over IPv6" allows you to access the IPv4 network as usual so that IPv4 information can be exchanged through the IPv6 network.For this reason, if you use the V6 Plus, you will be able to access both IPv6 networks and IPv4 networks at the same time.
In the v6 plus, connect to the IPv6 network using the IPoE method.The IPoE connection is the same connection method as the Ethernet, and the IPv6 global address is assigned to the connection device, allowing direct communication with the IPv6 network.At the same time, the IPv6 global address is automatically assigned, so there is no need to set an ID or password for connection like PPPoE.
Furthermore, since it can be connected directly to the network, there is no need to go through the terminal ending device such as PPPoE, so there is no bottle neck and high -speed and low delay communication can be performed at all times.These points are the great benefits of V6 plus.
PPPoEでは接続用のIDやパスワードを設定する必要があるが、v6プラスは設定不要でインターネットにアクセス可能(JPNEのサイトより抜粋)There are many ISPs for V6 plus throughout the country, including NIFTY, So-net, and GMO Internet.In addition, most ISP does not require an option connection fee even when making a V6 plus connection, so it is nice that it can be used without additional charges.
