QoS. It includes virtual circuit-based VPN (vcvpn) and IP tunneling-based VPN. Divided by Protocol: VPN based on the second-layer service and VPN based on the third-layer tunnel. The second-layer service VPN is composed of a public frame relay or ATM network, it forwards data packets based on the layer-2 addresses of user data packets (such as MAC addresses, dlci of frame relay, and VPI/VCI of ATM) on the second layer of the network, the service pr

have a lot of impact on the security of the firewall. First, the firewall may not be able to identify specific conversion technologies or apply some filtering policies supported by native IPv6 traffic. For example, when using native IPv4 or native IPv6, a website can block packets destined for TCP port 25, but it may not block these packets after Teredo and other conversion mechanisms are deployed. Second, the conversion technology may aggravate the

The full name of the VPN is "virtual private network", the translation is "fictitious dedicated network". VPN is defined as a temporary, secure connection through a public network (usually the Internet), a secure, stable tunnel through a chaotic public network. VPN mainly uses tunneling technology, encryption and decryption technology, key management technology and user and equipment identity authentication technology. The functions that a VPN

package can be read as long as the Internet traffic is seen. This is obviously a problem if the company wants to use the Internet to transmit important trade secret information. The way in which the VPN overcomes these hurdles is tunneling: The packet is not exposed to the Internet, but is first encrypted to ensure security, which is then encapsulated by a VPN in the form of an IP packet, which is transmitted through the tunnel (see photo). To illu

require secure communication over the Internet, which is generally considered insecure. VPN security technology can reduce the security risks of data transmission over the Internet. It can replace expensive dedicated leased lines. From the user's point of view, it is irrelevant to establish a physical network for a tunnel, because it seems that information is transmitted on a dedicated private network. VPN tunneling encapsulates data in IP packet gro

Introduction to LVS Load balancingTypical open source software for load Balancing clusters: lvs,nginx,haproxy,lighttpd.High-availability clusters typically commonly used open source software: keepalived,beartbeatCommercial hardware load devices: F5, NetscaleLoadBalancer is the load scheduler, which dispatches network requests to the real server without gaps. LVS has three load balancing techniques, namely NAT, Dr, TUN, Full-nat.There are 4 main types of LVS operating modes:DRNatTunnelFull-natIP

/nat Technology, which is the virtual server via Network Address translation. The IP tunneling technology is the Vs/tun (virtual server via IP tunneling) and the method of searching for servers via direct routing vs/dr (virtual server via direct Routing), Both of these methods can greatly improve the scalability of the system. So, Ipvs software realizes three kinds of IP load balancing technology.For the ab

Take a look at Vpn,vpn (virtual private network, VPN) is a secure, point-to-point connection through a private network or a public network. The VPN client uses a specific tunneling protocol to establish a virtual connection with the VPN server. The best example of a VPN is a VPN client that uses a VPN connection to a VPN server connected to the Intenet. It works by the VPN server to answer the identity of the VPN client, and if authenticated, the int

One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1.

PPTP Point-to-Point Tunneling Protocol (PPTP) is a Point-to-Point tunneling protocol developed by a PPTP forum consisting of companies such as Microsoft and 3com, which uses cryptographic algorithms such as PAP or CHAP, based on dial-up PPP protocols, Or use the Microsoft Point-to-Point Encryption algorithm MPPE.

As we all know, because VPN (Virtual Private Network) transmits private information, VPN users are concerned about data security. Currently, VPN uses four technologies to ensure security. These four technologies are Tunneling, Encryption and Decryption, and Key Management) user and device Authentication technology (Authentication ). 1. Tunneling Technology: The tunnelin
