Abstract

A system receives a first request from a first instance of a network function associated with a first address. The system may determine the first address and, based at least in part on the first address, may identify a second address with which to respond to the first request. The system may then send, to the first instance of the network function, a response to the first request specifying the second address. The system may also receive a second request from a second instance of the network function associated with a third address. The system may determine a fourth address with which to respond to the second request, and may thereafter send a response to the second request to the second instance of the network function, with the response specifying the fourth address.

Claims20

Dependent claims

A system comprising:

one or more processors;
and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising:
storing an association between a first address associated with a first instance of a network function and a second address associated with the system;
and
storing an association between a third address associated with a second instance of the network function and a fourth address associated with the system;
receiving a first request from the first instance of the network function;
identifying the first address from the first request;
determining that the first address is associated with the second address;
sending, to the first instance of the network function, a response to the first request, the response to the first request specifying the second address;
receiving a second request from the second instance of the network function;
identifying the third address from the second request;
determining that the third address is associated with the fourth address;
and
sending, to the second instance of the network function, a response to the second request, the response to the second request specifying the fourth address.

12 more elements

A method implemented at least partly by a system, the method comprising:

storing an association between a first address associated with a first instance of a network function and a second address associated with the system;
and
storing an association between a third address associated with a second instance of the network function and a fourth address associated with the system;
receiving a first request from the first instance of the network function;
identifying the first address from the first request;
determining that the first address is associated with the second address;
sending, to the first instance of the network function, a response to the first request, the response to the first request specifying the second address;
receiving a second request from the second instance of the network function;
identifying the third address from the second request;
determining that the third address is associated with the fourth address;
and
sending, to the second instance of the network function, a response to the second request, the response to the second request specifying the fourth address.

9 more elements

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause one or more processors of a system to perform acts comprising:

storing an association between a first address associated with a first instance of a network function and a second address associated with the system;
and
storing an association between a third address associated with a second instance of the network function and a fourth address associated with the system;
receiving a first request from the first instance of the network function;
identifying the first address from the first request;
determining that the first address is associated with the second address;
sending, to the first instance of the network function, a response to the first request, the response to the first request specifying the second address;
receiving a second request from the second instance of the network function;
identifying the third address from the second request;
determining that the third address is associated with the fourth address;
and
sending, to the second instance of the network function, a response to the second request, the response to the second request specifying the fourth address.
