frequently. In the traditional way, the change of IP address will lead to communication terminal. To solve this problem, mobile IP technology refers to the principle of processing cellular mobile phone calls, so that mobile nodes adopt a fixed IP address, a login can be achieved in any location to maintain a single link layer with the IP host, so that communication continues. Before introducing mobile IP technology, here are a few important concepts to start with:Mobile Agent (mobility agent):

You use virtual server via IP tunneling or virtual server via direct routing for better scalability. You can also nest the load balancer, at the front end is a vs-tunneling or vs-drouting

Introduction of a LVS IP tunnel modeIP tunneling (IP tunneling) is the technique of encapsulating an IP message in another IP packet, which enables a packet of data that is targeted for one IP address to be encapsulated and forwarded to another IP address. IP tunneling technology is also known as IP encapsulation Technology (IP encapsulation). IP

;Considerations for DA Configuration: Windows Firewall for computers in the domain must be enabled to block the Allow and block entries in the default profile because disabling the Windows Firewall service also disables IPSec If you want to enable a client to connect by using Teredo, the DirectAccess server must have two contiguous public IPV4 addresses configured on the external physical interface, and the DA server cannot be behind the NAT dev

dual-stack on the server, followed by the edge computer system. Another approach is to transmit another protocol within one protocol using a tunnel. This type of tunnel encapsulates an IPv6 package in an IPv4 packet and transmits it in the network section that is not upgraded to IPv6. Tunnels can be established in different network application environments with IPv6 isolated from the IPv4 ocean. This is common in the early stages of IPv6 migration. However, in the future, this approach will bri

the current status, migrate to the next status. The TCP State migration of VS/DR is performed according to the semi-connected TCP finite state machine. Virtual Server (VS/TUN) through IP tunneling) Similar to VS/DR, VS/TUN is an asymmetric feature of most Internet services. The Server Load balancer only schedules requests, and the server directly sends the requests to the customer, this greatly improves the throughput of the entire cluster system. I

VPN protocols: PPTP, L2TP, and OpenVPN1. Concepts of PPTP, L2TP, and OpenVPN Tunneling Protocols 1. Default port number of PPTP (Point to Point Tunneling Protocol): 1723 PPTP, or PPTF Protocol. This protocol is a new enhanced security protocol developed on the basis of the PPP protocol. It supports multi-protocol Virtual Private Network (VPN) and can pass the password authentication protocol (PAP) and Exten

mechanisms for this:1. Vs/nat (Virtual server via network address translation), that is, the network addresses rollover technology to implement virtualized servers.When the request arrives, the program processed on the Diretor server changes the destination address (that is, the virtual IP address) in the data message to a specific real server, the port is changed to the real server port, and then the message is sent to the real server. After the Real server finishes processing the data, it nee

Microsoft is currently developing a remote Access tunneling protocol for Vista and Longhorn server. This protocol will enable user devices to securely access the network from any location on the internet via a VPN without worrying about common port blocking issues. Advantages of SSTP In the 14th issue of the technical features of the internet world, the reporter introduced Microsoft's latest SSTP (Secure Sockets

, such as Cisco's LocalDirector, F5 big/ip, and Alteon acedirector. On the basis of analyzing the disadvantage of vs/nat and the asymmetry of network service, we propose the method of implementing virtual server through IP tunneling Vs/tun (virtual server via IP tunneling), and the method of implementing the dummy server through direct routing vs/ DR (Virtual Server via Direct Routing), which can greatly im

: direct routing (directly forwarding), network address translation (NAT) and tunneling Technology (tunneling). Direct forwarding is a method that can be used when the computer participating in the cluster is on the same network segment as the computer that is managing the control. When a control-managed computer receives a request package, it is sent directly to the node participating in the cluster. Its

that policy has not been updated, security is not guaranteed. IPsec filters are inserted into the IP layer of the TCP/IP network protocol stack on the computer, so these filters can be checked (filtered) for all inbound or outbound IP packets. IPsec is transparent to end user applications and operating system services, in addition to a slight delay (which inevitably causes delays in negotiating security relationships between two computers). The filter is associated with the corresponding filter

. The tunnel method requires the tunnel end node to use other mechanisms to obtain its IPv4 address, for example, the configuration mechanism of d h c p, manual configuration, or other IPv4 is used. If you are using a notebook and often debug the network. In WINDOWS 7, an IPV6 tunnel is automatically created. Usually we can see many tunnels using ipconfig/all. For example, if I have more than 40 tunnels and want to view IPv4 information, it will flash and cause inconvenience to use. This is beca

Use ipconfig to view many useless tunnel adapters. How to delete it? In Windows 7, the system automatically generates multiple tunnel connections. These tunnel connections are used to achieve mutual access between IPv4 and IPv6 (the IPv6 tunnel encapsulates IPv6 packets in IPv4 packets, allow IPv6 data packets to communicate over networks that use the IPv4 address protocol. For devices using tunnel technology, IPv6 datagram is encapsulated into IPv4 at the entrance of the tunnel. The source and
