Modular fabric internal datapath

A method comprising:

• providing one or more design files modeling a datapath comprising a plurality of ports, a first backbone coupling the plurality of ports, and a second backbone coupling the plurality of ports, the one or more design files comprising a configuration parameter for the datapath;
• and
• exposing the configuration parameter to accept one of:
• a first value and a second value,
• wherein the one or more design files are to be loaded by a design tool;
• wherein the one or more design files are to instantiate the first backbone when the configuration parameter is set to the first value;
• and
• wherein the one or more design files are to instantiate the second backbone when the configuration parameter is set to the second value.

A system comprising a memory, a processor coupled to the memory, and a wireless interface for allowing the processor to communicate with another device, the system comprising:

• a first circuitry comprising a plurality of first ingress ports, a plurality of first egress ports, and a bus, at least two of the first ingress ports and at least two of the first egress ports being coupled to the bus;
• and
• a second circuitry comprising a plurality of second ingress ports and a plurality of second egress ports, at least two of the second ingress ports being one-to-many coupled to at least two of the second egress ports,
• wherein at least one first ingress port is one-to-one coupled to a second egress port, and at least one second ingress port is one-to-one coupled to a first egress port.
