IPV6 and IPv4 are two completely different network protocols, since the current IPV4 to IPV6 in the future to be replaced, then it is in the end edge where? First of all, IPV6 addresses with a large capacity. IPV6 Address 128-bit length, the current 32-bit IPV4 address, the additional IP addresses can be used simply to describe mass. IPV4 addresses can only provide a maximum of two addresses in the 32 th power, but also remove some of the private address, and reserved addresses are actually available to be less than this number. The IPV6 address for up to 2 ^ 128 addresses, in the future no matter what network device join the network can be assigned to a sufficient address. IPV6 This is the biggest advantage, of course, relative to the IPV4, IPV6 also has a better Qos support, a more streamlined IPV6 header to facilitate networking equipment to IPV6 packet processing, and provide support for convection, as well as enhanced security and so on.
The current form of IPV4 addresses are...

1. OSI7 layer model
from the bottom layer of 1 to 7, respectively: Application Layer (Applicationlayer) layer (Presentationlayer) session layer (Sessionlayer) Transport Layer (Transportlayer) network layer (Networklayer) Data Link Layer (Datalinklayer) Physical Layer (Physicallayer) where the three known high-level, defined communication between applications and the human-machine interface. What does that mean, that is, the three-tier is responsible for the computer can understand things that you can read into things, or to something you can read into a computer can understand things. Under the four-story called bottom of the definition of how the end to end transmission of data (end-to-end), the physical specifications, as well as data and optical signals between the conversion. The following strata to another, to illustrate: the application layer, is very simple application. This layer is responsible for identifying communic...

VPN (Virtual Private Network) to develop so far is no longer a simple encrypted access to the tunnel, and it has integrated the access control, traffic management, encryption, routing, availability management and other functions, and in the global information security system play an important role. There are also online, the comparative advantages and disadvantages of the various VPN protocols are eyes of the beholder, the wise see wisdom, a lot of technical personnel for the purpose of use due consideration, including access control, security and user easy to use, flexible expansion of other aspects, on balance difficult trade-offs; especially in the VOIP voice environment, network security is particularly important, so now a growing number of Internet telephony and voice gateways to support VPN protocols.

A little size of any network, running a long time, there will always inevitably encounter some network failure; for many network problems, we tend to failure as long as the specific phenomenon, we can probably determine the reasons for failure occurred, and network problems can be resolved swiftly away! But there are also a number of factors that a network failure caused by upsets, these less popular because of rare elements, we exclude the time of such failures are often easy to overlook them, and thus much easier to make detours, affecting the efficiency of the network trouble-shooting. This does not, this article describes a network following failure, turned out to be caused by the loop due to the switch itself, given the small chance of failure there, and now this would exclude the process of restoring it out, with the share exchange!

Underwater acoustic sensor networks, an important use of underwater sensor node is covered by the region long-term underwater early warning, target detection, monitoring, and other elements of the marine aquatic environment; the same time, in the future multi-base and outboard distributed sensor system constitutes the vast network of anti-submarine warfare, and underwater data communications is the key, and bear the detection of underwater sensor networks, data communication important mission. The so-called underwater wireless sensor networks is underwater in a certain area, through a variety of underwater sensor nodes to obtain information, and nodes underwater acoustic communications and networking, the eventual adoption of a specific node and re-establish radio and cable in the form of the coverage area in the acquired information into the shore of the regular network, and sent to an underwater observer subnet.
