US 2021/0281637 A1 · MANAGEMENT FOR A LOAD BALANCER CLUSTER

Abstract

In an approach to managing a load balancer cluster, one or more computer processors receive a packet comprising a source IP address of the packet. The one or more computer processors determine whether there is a record comprising the source IP address of the packet either in the load balancer or in the assistant. The one or more computer processors, responsive to determining there is no such record in the load balancer and there is the record in the assistant, obtain the record from the assistant, the record also comprising information of a first server in a server cluster and the first server being referred to as a destination server for any packet from the source IP address. The one or more computer processors send the packet to the first server.

Dependent claims

A computer-implemented method implemented in a load balancer cluster, the load balancer cluster comprising a plurality of load balancers and an assistant, the method comprising:

determining, by the one or more computer processors, whether there is a record comprising a source internet protocol (IP) address of a received packet either in a load balancer or in the assistant;
and
responsive to determining there is no said record in the load balancer and there is the record in the assistant:
obtaining, by the one or more computer processors, the record from the assistant, wherein the record comprises information of a first server in a server cluster and the first server being referred to as a destination server for any packet from the source IP address wherein obtaining the record from the assistant comprises:
selecting, by the one or more computer processors, a server from the server cluster to be the first server;
generating, by the one or more computer processors, the record in which the source IP address and the information of the first server are included;
storing, by the one or more computer processors, the record to the load balancer;
and
sending, by the one or more computer processors, the packet to the first server.

6 more elements

A load balancer in a load balancer cluster, the load balancer cluster comprising a plurality of load balancers and an assistant, the load balancer comprising:

one or more computer processors;
one or more computer readable storage media;
and
program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the stored program instructions comprising:
program instructions to determine whether there is a record comprising a source internet protocol (IP) address of a received packet either in a load balancer or in the assistant;
and
responsive to determining there is no said record in the load balancer and there is the record in the assistant:
program instructions to obtain the record from the assistant, wherein the record comprises information of a first server in a server cluster and the first server being referred to as a destination server for any packet from the source IP address, wherein the program instructions to obtain the record from the assistant, comprise:
program instructions to select a server from the server cluster to be the first server;
program instructions to generate the record in which the source IP address and the information of the first server are included;
program instructions to store the record to the load balancer;
and
program instructions to send the packet to the first server.

10 more elements

A computer program product, comprising a computer readable storage medium having program instructions stored on one or more computer readable storage media, the stored program instructions executable by a load balancer in a load balancer cluster which comprises a plurality of load balancers and an assistant, the stored program instructions comprising:

program instructions to determine whether there is a record comprising a source internet protocol (IP) address of a received packet either in a load balancer or in the assistant;
and
responsive to determining there is no said record in the load balancer and there is the record in the assistant:
program instructions to obtain the record from the assistant, wherein the record comprises information of a first server in a server cluster and the first server being referred to as a destination server for any packet from the source IP address, wherein the program instructions to obtain the record from the assistant, comprise:
program instructions to select a server from the server cluster to be the first server;
program instructions to generate the record in which the source IP address and the information of the first server are included;
program instructions to store the record to the load balancer;
and
program instructions to send the packet to the first server.
