Embodiment Construction

[0015] In various embodiments, the present invention proposes a fault-tolerant network architecture for increasing network availability. It should be understood that the systems and methods described below may include various other components and / or processes in actual implementations.

[0016] figure 1 One embodiment of a fault-tolerant network 10 according to aspects of the invention is shown. In this embodiment, fault-tolerant network 10 includes a first node (Node A) 110 and a second node (Node B) 120 . It should be understood that fault-tolerant network 10 may include any number of nodes in various embodiments.

[0017] Each of the nodes 110, 120 may be a server or host such as a computer or computer system for providing resources to one or more users. Generally, nodes 110 , 120 include software and hardware components for communicating with each other over network 130 . Nodes 110, 120 may be constructed and arranged to communicate using various communication and / or r...

Abstract

The present invention provides a fault tolerant network structure using network nodes comprising a first network interface to an addressable network. The first network interface IP address defined by the first IP address range is assigned to the first network interface. The network node also includes at least one virtual IP address defined by an IP address range outside the first IP address range. At least one virtual IP address is advertised to the addressable network from the first network interface, and packets addressed to the at least one virtual IP address may be routed to the first network interface.

Description

technical field [0001] The present invention generally relates to systems and methods for increasing network availability, and more particularly, to systems and methods for increasing network availability through the use of fault-tolerant network architectures. Background technique [0002] In Internet Protocol (IP) networks, reducing downtime and achieving high availability are very important. One way to achieve high availability is to share single or multiple IP addresses between two (multiple) network hosts. The operation of switching the owner of the shared IP address between hosts is called floating, and the shared IP address is called a floating IP address. Only one host can have the drift IP address at any given moment. [0003] Hosts that are configured so that their IP addresses float among them are called High Availability (HA) nodes. All HA nodes that may have drifting IP addresses form an HA cluster. Only one HA node in the HA cluster can have an IP address a...
