Method and apparatus for maintaining connection state between a connection manager and a failover device
First Claim
1. A method of maintaining a state of a virtual connection supported by an active connection manager on a standby connection manager comprising:
- configuring the standby connection manager to include a physical machine object that stores a physical IP address of a physical machine that is available to the active connection manager and a virtual machine object that stores a virtual IP address of a virtual machine that is implemented on the active connection manager;
receiving a replication packet at the standby connection manager from the active connection manager wherein the replication packet includes a foreign IP address, the virtual IP address and the physical IP address;
storing a standby connection object in the standby connection manager that includes the foreign IP address, the virtual IP address and the physical IP address from the replication packet; and
updating a virtual machine counter in the virtual machine object when a replication packet is received that includes the virtual IP address.

Abstract
A system and method are disclosed for maintaining the state of a virtual connection supported by an active connection manager on a standby connection manager. The method includes configuring the standby connection manager to include a physical machine object that stores a physical IP address of a physical machine that is available to the active connection manager and a virtual machine object that stores a virtual IP address of a virtual machine that is implemented on the connection manager. A replication packet is received at the standby connection manager from the active connection manager wherein the replication packet includes a foreign IP address, the virtual IP address and the physical IP address. A standby connection object is stored in the connection manager. The standby connection object includes the foreign IP address, the virtual IP address and the physical IP address from the replication packet on the standby connection manager.

17. A method of maintaining a state of a virtual connection supported by an active connection manager on a standby connection manager, comprising:
-
configuring the standby connection manager to include a physical machine object that stores a first physical IP address of a physical machine that is available to the active connection manager and a virtual machine object that stores a first virtual IP address of a virtual machine associated with a first virtual connection that is implemented on the active connection manager; receiving a replication packet at the standby connection manager from the active connection manager wherein the replication packet includes a first foreign IP address, the first virtual IP address, the first physical IP address, a second foreign IP address, a second virtual IP address, and a second physical IP address, wherein the second foreign IP address, the second virtual IP address, and the second physical IP address correspond to a second virtual connection that is associated with the first virtual connection; and storing a standby connection object in the standby connection manager that includes the first foreign IP address, the first virtual IP address and the first physical IP address from the replication packet. - View Dependent Claims (18, 19, 20, 21, 22, 27)
