Abstract
Methods and systems for a network device are provided. The network device includes a stage one arbiter for a base-port for determining if there are any pending requests; blocking any other requests from a same receive queue destined for a same sub-port, same physical transmit queue, and same virtual transmit queue when there are any pending requests; selecting a group of requests with a highest priority and available resources; selecting at least two of the highest priority requests; selecting an oldest one of the requests having the same priority when there are requests with a same priority; sending the selected requests to a stage two arbiter for the base-port; and determining if any new requests have been made or if any previously pending requests have been removed.
