Distributed subnet manager for infiniband networks

A method for distributed management of a network, the method comprising:

• discovering, by one or more processors, a network, wherein the network is comprised of a plurality of nodes and at least one switch;
• identifying, by one or more processors, a first port associated with the at least one node;
• identifying, by one or more processors, a link between the first port and a second port within the network;
• determining, by one or more processors, the at least one link is properly configured;
• selecting, by one or more processors, a first node of the plurality of nodes, wherein the first node provides subnet administrator functionality;
• determining, by one or more processors, that the first node is not a master node, wherein the master node is configured to manage the network;
• identifying, by one or more processors, a second node that is the master node;
• determining, by one or more processors, that the second node has entered a standby mode;
• selecting, by one or more processors, the first node to be the master node;
• initializing, by one or more processors, a routing table, wherein the routing table contains locations of each node of the plurality of nodes and a location of the at least one switch;
• identifying, by one or more processors, a change to the network;
• identifying, by one or more processors, that a third node within the network is malfunctioning;
• establishing, by one or more processors, a routing path, wherein the routing path is a cross node routing path;
• identifying, by one or more processors, that a fourth node is non-responding;
• resetting, by one or more processors, a port associated with the fourth node;
• assigning, by one or more processors, a network address to each node incorporated into the network;
• invalidating, by one or more processors, network addresses associated with each node removed from the network;
• determining, by one or more processors, that an address associated with at least one port has changed;
• invalidating, by one or more processors, the address associated with the at least one port;
• identifying, by one or more processors, an updated address associated with the at least one port;
• and
• adjusting, by one or more processors, the routing table to include the updated address associated with the at least one port, based on the change to the network.
