Enabling a protocol for efficiently and reliably using the NVME protocol over a network, referred to as NVME over Network, or NVMEoN, may include an NVMEoN exchange layer for handling exchanges between initiating and target nodes on a network, a burst transmission protocol that provides guaranteed delivery without duplicate retransmission, and an exchange status block approach to manage state information about exchanges.

A method is performed in a requester device that is coupled with a responder device by a serial interface. The method is one of selecting an approach to handle an error in a request-response communication between the requester and responder devices over the serial interface. The method includes transmitting a request packet, of the request-response communication, over the serial interface, based on a request from an application that is executing on a logical processor. The method includes reporting the error in the request-response communication to an application-layer module. The method includes selecting an error handling approach, of a plurality of error handling approaches, which is to be used to handle the error, with the application-layer module.

Reporting errors on serial interfaces to application layers for flexible error handling approach selection

Embodiments of the invention include a method performed in a packet processor core for policing a packet through a hierarchical policer coupled to one or more policing requestors. The hierarchical policer has a plurality of meter levels including an initial level and one or more subsequent levels. The hierarchical policer creates a meter result at the meter of each meter level using packet characteristics and a meter state for that meter level. The hierarchical policer generates meter level outputs that classify the packet for each meter level and for at least one of the subsequent levels the meter level output is based on the meter level output from a previous meter level. The hierarchical policer performs a meter combine operation that produces a final packet output attribute from the combination of the meter level outputs. The hierarchical policer returns the final packet output attribute to a policing requestor.
