Abstract: One aspect of the instant application can provide a networking device. The networking device can include a set of Compute Express Link (CXL) ports, a set of non-CXL ports, a set of bridge circuits associated with the set of CXL ports, and an interconnect. A respective bridge circuit can include a packet-conversion subcircuit to convert a CXL packet received at a corresponding CXL port to a customized packet and a protocol-conversion subcircuit to convert a CXL protocol to a customized protocol implemented by the networking device. The interconnect can switch customized packets among the CXL and non-CXL ports based on the customized protocol.

Abstract: A lossy fabric transmitting device includes a queue, a link transmitter to transmit packets from the queue, a trigger mechanism to automatically discard a packet contained in the queue in response to satisfaction of a packet dropping threshold and a discard counter to track packets being discarded from the queue. The discard counter has a failure detection threshold. The discard counter resets in response to the link transmitter transmitting a packet. Satisfaction of the failure detection threshold identifies the link transmitter as being immediately adjacent a failed link of a lossy fabric.

Abstract: A component group table in a receiving node of a computer network stores access permission information for enabling the receiving node to validate an access request issued by a requesting node. An incoming access request at a receiving node includes a subnet ID/component ID (“SID/CID”) tuple. The receiving node selectively computes a component group table address for the requesting node according to an address mapping function determined by the value of at least one predetermined bit within the SID/CID tuple of the incoming access request. Using at least one bit in the SID/CID tuple enables the establishment of at least two address mapping regions in the component group table, such as separate regions for storage nodes and compute nodes in the network.
