Virtual IP address (VIP) is an IP address that is not connected to a network interface card (NIC) in a specific computer or a computer. The data packet is sent to this VIP address, but all data is still through the real network interface. Most of VIPS is used for connection redundancy; a VIP address may also be available when a computer or NIC fails, and is handed over to another optional computer or NIC response connection. Examples of virtual IP addresses such as: a loopback (circuit -free IP address) as an IP address related to any specific interface (or circuit) in the host or router. For example. We all know that under the architecture of TCP/IP, all computers who want to get on the network , no matter what the way to use the network, must have a unique ip-address. In the two most common examples: the school's computer's network cable is connected together, through the Ethernet interface connecting to the network, then the Ethernet interface must have an IP-addr. The Ethernet IP of .NTU.E.TW is 140.112.52.20. Another common network interface is PPP, usually on the Modem dial. When you dial from the Modem Server through the Modem, there are some Server will be established from it. The distance between the PPP line between the distance between the distance between your computer? R n is automatically performed), so you can connect to the outside through the Modem (PPP), as if your computer is directly connected to the network.
Virtual IP (VIP: Virtual IP) The virtual IP address (VIP) is an IP address that is not connected to a network interface card (NIC) in a computer or in a computer. The introduced groups are sent to this VIP address, but all group travels pass through the actual network interface. VIPS is mostly used for connection redundancy; a VIP address may also be available when a computer or NIC fails because an optional computer or NIC response connection. An example of a virtual IP address is a loopback (circuit -free IP address) as an IP address related to any specific interface (or circuit) in the host or router.
After assigning the virtual IP address to the AIX system, the IP address can no longer depend on the specified network interface. The sender only needs to send the package to the virtual IP address of the receiver's server (all the receiving packages still reach the server through the real physical network interface). Before the virtual IP address is used, if a network interface fails, all related connections () will be lost. With the virtual IP address, the AIX system needs to provide automatic re -routing support for the virtual interface and network router. As long as the package can be re -routing to other network interfaces, the connection to the virtual IP network interface will not be interrupted. Therefore, the virtual IP address can block the fault caused by the network card, router, etc., so that the connection can be retained. The failure of the network card will not affect existing connections. The use of virtual IP addresses on AIX further improves the usability of the system. At the same time, there are multiple network cards to jointly bear the load of the system, which can reduce the centralized use of a single network card and a subnet to solve the bottleneck brought by it. The function of VIPA in AIX is transparent to network devices and does not require special P series or network devices. To implement a virtual IP address on the IBM P series server, you need: (1) AIX5L. (2) More than two connect to the corporate network, not in the IP interface of the same subnet (in the same way of physics).
