METHOD FOR IMPROVED LOAD DISTRIBUTION RELATING TO THE PROVISION OF A NETWORK SERVICE IN A COMPUTER NETWORK, SYSTEM FOR IMPROVED LOAD DISTRIBUTION RELATING TO THE PROVISION OF A NETWORK SERVICE IN A COMPUTER NETWORK, PROGRAM AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method of improved load sharing for providing a network service in a computer network, the computer network comprising a plurality of servers for providing the network service to a client device, the plurality of servers comprising a plurality of primary servers, the plurality of servers including at least one secondary server for failover wherein the computer network comprises a Domain Name System (DNS) server for providing Service Resource Record (SRV) records, the Service Resource Record (SRV) records having load distribution data and prioritization data, the client device communicating with the computer network to use the Network service, the method comprising the following steps:Determining, by the client device, a first server, wherein the first server is selected from the plurality of primary servers in dependence on the load distribution data of the service resource record (SRV),Providing, in the case where the first server is available to provide the network service to the client device, the network service to the client device through the first server; and in the event that the first server is for deployment the network service to the client device fails and another server of the plurality of primary servers is available to provide the network service to the client device - determining, by the client device, a second server from the at least one secondary server, the second server in Dependency of the load distribution data of the service resource record (SRV) records is determined from the at least one secondary server, wherein - if the second server for a service use by the client device is available - the network service is provided to the client device by the second server.
