Patent number: 11909710Abstract: A method for communication includes provisioning each node in a network with a respective set of two or more network addresses. Each node in succession is assigned a respective network address from the respective provisioned set that has not been assigned for use by any preceding node. Upon finding for a given node that all the network addresses in the respective provisioned set were assigned to preceding nodes, the preceding nodes are searched to identify a candidate node having an additional network address in the respective provisioned set, other than the assigned respective network address, that was not yet assigned to any of the nodes. The additional network address is assigned to the candidate node instead of the respective network address that was previously assigned to the candidate node, and the assigning of the network addresses to the nodes in the succession resumes following the candidate node.Type: GrantFiled: July 7, 2022Date of Patent: February 20, 2024Assignee: MELLANOX TECHNOLOGIES, LTD.Inventors: Eitan Zahavi, Guy Rozenberg, Matty Kadosh, Lion Levi, Boris Pismenny, Alex Netes, Miriam Menes, Lior Hodaya Bezen, Michael Tahar
