Abstract

A method of operating a network subnet manager, in particular Infiniband network subnet manager in a subnet of a network. Only one subnet manager entity can be master within a subnet. A problem related with this specification is that a specific vendor implementation may exist with many features and internal functionality that are not specified in the network specification. If such a subnet manager loses its exclusivity because another subnet manager enters the subnet, having higher priority, the additional features from the vendor implementation can no longer be used in the subnet. The proposed method solves this problem by allowing a subnet manager that has a lower hierarchy level and thus lower priority to maintain its managing operation by becoming the master subnet manager again.
