Multipath effectuation within singly contiguous network fabric via switching device routing logic programming

A method comprising, responsive to a network fabric login request initiated by a first node:

• by a network fabric forwarder device,
• creating a network fabric port and a network fabric address for the first node;
• acquiring a list of one or more network fabric ports of one or more second nodes associated with the first node;
• determining a network fabric address for the given target node of each network fabric port within the list;
• by a network fabric controller device, determining, using the network fabric addresses of the first node and of the second nodes, a path between the first node and the network fabric forwarder device through the singly contiguous network fabric and loading the path into a forwarding table of each switching device within the path,
• such that multipaths for transmission of data through the singly contiguous network fabric from the first node and the second nodes are effected,
• wherein the network fabric forwarder device and the network fabric controller device are each control-path or programming-path connected to each switching device, the network fabric controller device does not directly route the data, and the switching devices route the data between the first node and the second nodes.

A network fabric controller device comprising:

• network connection hardware to connect the network fabric controller device to a singly contiguous network fabric including a plurality of switching devices to route data between a first node and one or more second nodes, each of the first node and the second nodes having a network fabric port and a network fabric address;
• and
• network managing logic to determine, using the network fabric addresses of the first node and of the second nodes, one or more paths between the first node and the second nodes through the singly contiguous network fabric and to load the paths into a forwarding table of each switching device, such that multipaths for transmission of data through the singly contiguous network fabric from the given initiator node and the given target nodes are effected,
• wherein the network fabric controller device is control-path or programming-path connected to each switch device and does not directly route the data, and the switching devices route the data between the first node and the second nodes.
