Abstract:
1. A method, comprising: defining a key-configured topology group that identifies a group of member nodes that are authorized to communicate with each other, and for causing a group member key to be generated that validates membership of a node in the key-configured topology group; in a first node, receiving from a second node, via a preferred computer networking protocol, a request to establish a connection between the first node and the second node via the preferred computer networking protocol, where the connection facilitates the second node having remote direct memory access to a resource associated with the first node; determining whether the request includes a key; if the key is included, determining whether the key is a valid group member key from the key-configured topology group and whether the second node is a member in the key-configured topology group; and performing one of, selectively establishing the connection between the first node and the second node via the preferred computer networking protocol that provides the second node remote direct memory access to the resource on the first node, and selectively refusing to establish the connection via the preferred computer networking protocol and instead permitting the connection via a fallback protocol if the key does not establish valid membership for the second node in the key-configured topology group, where the fallback protocol comprises a different protocol than the preferred computer networking protocol.
