摘要： A method for hierarchical occupancy based congestion management includes receiving, by a computing device, a plurality of data flows, each of the plurality of data flows is received from a source and includes a plurality of data packets and storing the plurality of data packets in a buffer including multiple storage units. The method includes determining if the buffer is congested, responsive to determining the buffer is congested randomly selecting at least two occupied units of the buffer and identifying a source of each of the data packets stored in the occupied units of the buffer and generating a congestion notification message. The method also includes comparing a selection criterion associated with each identified source to determine which identified source has a higher selection criterion and sending the congestion notification message to the identified source with the higher selection criterion.

摘要： A system for hierarchical occupancy based congestion management includes a buffer embodied in a computer readable storage medium including a plurality of buffer units for storing packets of a data flow received from sources. The system includes a buffer manager that stores information about the packets stored in the buffer, including a selection criterion associated with each of the plurality of sources and a congestion estimator that monitors a congestion level in the buffer. The system also includes a occupancy sampler that randomly selects at least two occupied buffer units from the plurality of buffer units and identifies the source of the packet stored in each of the occupied buffer units and a congestion notification message generator that generates a congestion notification message; wherein if the congestion level in the buffer exceeds a threshold value the congestion notification message is sent to the identified source with a higher selection criteria.

摘要： A method for hybrid arrival-occupancy based congestion management includes increasing a recent arrivals counter associated with a data flow from one or more sources in response to receiving a data packet from one of the sources and storing the data packet in a buffer including multiple storage units. The method includes determining if a buffer is congested, randomly selecting an occupied unit of the buffer and determining the source of the packet stored in the occupied unit of the buffer, generating a congestion notification message, sending the congestion notification message to the source of the packet stored in the occupied unit of the buffer if the recent arrivals counter exceeds a threshold value and decreasing the recent arrivals counter associated with the source of the packet stored in the occupied unit of the buffer and discarding the congestion notification message if the recent arrivals counter has a zero value.

摘要： IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

摘要： A system for deadlock resolution in end-to-end credit protocol includes a plurality of source controllers configured to receive data frames on an incoming link, wherein each source controller includes a plurality of credit counters. The system also includes a plurality of end controllers configured to receive data frames from the plurality of source controllers, wherein each end controller includes a buffer credit counter, a plurality of request counters, and an output buffer. Each of the plurality of credit counters corresponds to one of the plurality of end controllers and stores a number of credits received from that end controller. The buffer credit counter of each end controller stores a number of available credits of the end controllers. Each of the request counters corresponds to one of the plurality of source controllers and stores a number of credit requests received from that source controller.
