1. A method for allocating an IP address for an instance in a network function virtualization (NFV) system, comprising:
- obtaining, by a first node in the NFV system, a first requirement of IP address allocation for the instance from a virtualised network function descriptor (VNFD);
determining, by the first node, a second requirement of IP address allocation for the instance according to the first requirement; and
sending, by the first node, to a second node in the NFV system the second requirement, wherein the IP address is allocated for the instance based upon the second requirement.

Abstract
A method for allocating an IP address for an instance in a NFV system includes obtaining a first requirement of IP address allocation from VNFD by a first node in the NFV system. A second requirement of IP address allocation for the instance is determined according to the first requirement. Then the second requirement is sent to a second node in the NFV system that allocates the IP address for the instance.

13. A system, comprising:
-
a memory that stores at least one range of IP addresses; a processor that receives a request for an IP address for an instance in a Network Function Virtualization (NFV) system, wherein the processor allocates the IP address by obtaining a first requirement of IP address allocation for the instance from a virtualised network function descriptor (VNFD) and a second requirement of IP address allocation for the instance according to the first requirement, and an interface connected to the processor that sends a selected IP address to the instance based upon the second requirement. - View Dependent Claims (14, 15, 16)

17. A system, comprising:
-
a memory storing instructions; and a processor coupled to the memory, wherein when the processor executes the instructions, the instructions instruct the processor to; obtain a first requirement of IP address allocation for the instance from a virtualised network function descriptor (VNFD) in a network function virtualization (NFV) system; determine a second requirement of IP address allocation for the instance according to the first requirement; and send the second requirement to a node that allocates the IP address for the instance based upon the second requirement in the NFV system. - View Dependent Claims (18, 19, 20)
