NGN, or "Next Generation Network", is a general concept. Up to now, the next generation network has no definite definition. However, the features and main technologies of the Next Generation Network have gradually become apparent.
The features of the Next Generation Network mainly include: a) the network structure and function organization of the Next Generation Network should be an open distributed structure; B) the architecture of the Next Generation Network is actually IP technology + optical
Among the many features of the IPv6 protocol, we can feel the excellent services that the new network brings to us. In this article, we will introduce the automatic configuration and security features of the IPv6 protocol. Let's take a look at the content of automatic configuration.
Automatic Configuration of IPv6 protocol
1 stateless and stateful Configuration
Labels: IPv6 address: ipv6 local link address, IPv4 address
A huge IPv6 address space ensures that all cats and dogs have unique addresses.
The primary motivation of IPv6 is to meet the needs of the world's unique address. The number of IPv6 addresses is four times the numbe
◆ Configuration commands in WindowsXP/Windows2003:The IPv6 protocol stack is built in Windows2003. We recommend that you upgrade WindowsXP to SP1 at least.
1. First install the ipv6 protocol stack
C: \> ipv6 install
2. If you are accessing from a pure Ipv6 network environment, you can get the
3G technology is a complex system engineering, which requires some advanced technologies to ensure the implementation of this system engineering. In terms of 3G data service implementation, the IPv6 technology will be applied to the 3G network, specifically to the user's addressing, addressing and routing technology. IPv6 is the addressing, addressing, and routing technology for next-generation Internet con
With the depletion of IPv4 addresses, IPv6 is necessary for application. However, most networks around the world are still using IPv4, so the transition from IPv6 to IPv4 must be gradual, which is a relatively slow process, in this case, we need to use the IPv6 Tunneling Technology to connect the IPv4 network with the IPv6
In the network protocol, we have started to use the IPv6 protocol. Especially for mobile communication, IPv6 is also studied. Now we will describe the IPv6 Routing Protocol in mobile communication, hoping to help you understand this knowledge, in this way, we can have a deep understanding of our networks and communication protocols.
I.
With the development of mobile and broadband technologies, the demand for IP addresses will be even greater. For example, IP access from a large number of terminals requires more IP addresses. IPv4 is obviously unable to meet the needs of the next generation network for IP addresses. In addition to IP address problems, IPv4 also has a series of problems, such as a large route table, QoS, and mobility. IPv6 technology has been developed to solve addres
In the past few years, IPv6 has gradually become the mainstream, but many IT professionals are still helpless when facing IPv6. Indeed, IPv6 and IPv4 are quite different, this article is intended to help you eliminate IPv6 phobia.
1. The IPv6 address is a 128-bit hexadecimal
First, IntroductionLet's assume that the hosts discussed in this chapter support dual stacks, that is, support for IPV4 addresses, and Ipv6 addresses.We are talking about the point: the client and server side use different types of addresses. Because the same type of address has nothing to say.Second, IPV4 client and IPV6 serverThat is, the client uses the IPV4 address socket to communicate, and the server
When we upgrade from IPv4 to IPv6, are we fully prepared? Otherwise, many people still have some opinions on the IPv6 network protocol. After all, we have no doubt about new things. However, this does not prevent IPv6 from moving forward. What are IPv6 network protocol considerations for better service quality?
From th
As IPV4 addresses are expected to run out in 1012, all major telecom operators have begun to test their networks using IPV6 addresses. A project in our company is also testing the IPV6 network environment. We need to test the networks and servers where IPV6 addresses are deployed in different versions of windows. The following describes how to configure IP addres
The popularization of IPv6 protocol is only a matter of time, because in the current network status, the existing problems have made it imperative for us to change protocol standards. What are the characteristics of IPv6? Next we will summarize the eight features of IPv6. I hope it will be useful to you.(1) huge address spaceThe source and target addresses of
Two key transition technologies of metropolitan Area Network IPv6 transition Technology--nat444 and ds-lite, what are the basic factors to be considered when choosing two kinds of transition technologies? This blog post will give you a detailed description of the rationale for both technical solutions and how to deploy them later.
The large number of broadband users in the metropolitan area Network is the main force that consumes the network IPV4 add
Whenever our w764-bit flagship computer network failure, we all need to relate to a concept, that is IPV protocol, but in general, we set the adjustment, are IPv4 in the content of the agreement, we must have found that in the selection window, in addition to the IPv4, There is also a IPv6 that the agreement seems never to have been used. So is it necessary to exist? In fact, in our current system, this IPv6
1, first open the Start dialog box "command Prompt", open a command prompt window;
2, then we only need to use the following 3 commands to close the IPv6 interface, the Command Prompt window to enter the following command to run to resolve the shutdown IPv6.
netsh interface teredo set state disable
netsh interface 6to4 set state disabled
netsh interface isatap set state disabled

The check found that the IPV6 address was listening for Port 3306, and the client software does not support IPV6.
Newly opened system or configured IPV6 operating system, and then manually installed MySQL database or escort God installed database will appear t
The two major problems facing internet basic technology IPv4 are address resource depletion and backbone router route table explosion. These two problems are the defects of IPv4 protocol, only a large modification can be done. After years of discussion and comparison and trade-offs of various solutions, the next-generation IP protocol has been basically developed and assigned version 6, called IPv6.One of the key problems facing
