Abstract:
1. A method in a first control node for selecting the first control node or a second control node to act as a server for managing a master representation of a distributed shared memory being accessible within an overlay network, wherein the first and second control nodes and a subscription managing node are comprised in the overlay network, the overlay network being overlaid onto an IP-network, wherein the subscription managing node is configured to provide a communication channel of the overlay network between the first and second control nodes, the method comprising: obtaining a first indication relating to a ranking of a suitability of the first control node to manage the master representation of the distributed shared memory; sending a request for indications to the subscription managing node; receiving, over the communication channel, a second indication in response to the request for indications from the second control node via the subscription managing node, wherein the second indication relates to a ranking of a suitability of the second control node to manage the master representation of the distributed shared memory; and selecting, based on the first and second indications, one of the first and second control nodes to manage the master representation of the distributed shared memory.
