Abstract
A network node and a method for moveable IP based network resilience. A method at a first network node for IP address management in a network that is not capable to perform load balance with L3 or below information only comprises: determining whether a second network node, to which a first IP address is allocated, fails to function or not; and in response to determining that the second network node fails to function, de-allocating the first IP address from the second network node; and allocating the first IP address to a third network node, such that a fourth network node is enabled to route data, which is intended to be routed to the first IP address, to the third network node rather than the second network node.
Claims19
A method at a first network node for Internet Protocol (IP) address management in a network that is not capable to perform load balance with Layer 3 or below information only, the method comprising:
- determining whether a second network node, to which a first IP address is allocated, fails to function or not;
- and
- in response to determining that the second network node fails to function:
- de-allocating the first IP address from the second network node;
- and
- allocating the first IP address to a third network node, such that a fourth network node is enabled to route data, which is intended to be routed to the first IP address, to the third network node rather than the second network node.
A network node, comprising:
- a processor;
- and
- a memory storing instructions which, when executed by the processor, cause the processor to perform:
- determining whether a second network node, to which a first IP address is allocated, fails to function or not;
- and
- in response to determining that the second network node fails to function:
- de-allocating the first IP address from the second network node;
- and
- allocating the first IP address to a third network node, such that a fourth network node is enabled to route data, which is intended to be routed to the first IP address, to the third network node rather than the second network node.
