A network device is described that offers advanced traffic management and failure handling mechanisms to address AI/ML networking challenges. The network device includes an adaptive rail mapping that allows GPUs on different server computers in different parts of a network to communicate efficiently. Additionally, such communication between the GPUs is not disrupted in the face of failures. In one embodiment, the network device includes multiple forwarding modes wherein network traffic can proceed through different permutations of layers 1, 2, and 3 hardware. For example, the network device can dynamically change which layers of hardware that network packets travel through. Additionally, the network device can change a layer 1 mapping such that an input-port-to-output-port mapping can be reconfigured dynamically (without restarting the network device). Accordingly, the network device can route network traffic based upon a forwarding mode, which represents a desired data flow through the network fabric, and real-time network connectivity.
A method of forwarding traffic through a network device, the method comprising:
One or more computer-readable media comprising computer-executable instructions that, when executed, cause a computing system to perform a method comprising:
A network device, comprising:
