Apparatuses, methods and storage medium associated with routing data in a switch are provided. In embodiments, the switch may include route lookup circuitry determine a first set of output ports that are available to send a data packet to a destination node. The lookup circuitry may further select, based on respective congestion levels associated with the first set of output ports, a plurality of output ports for a second set of output ports from the first set of output ports. An input queue of the switch may buffer the data packet and route information associated with the second set of output ports. The switch may further include route selection circuitry to select a destination output port from the second set of output ports, based on updated congestion levels associated with the output ports of the second set of output ports. Other embodiments may be described and/or claimed.

The present technology is directed to a system and method for using cloud based processing to co-locate one or more tunnel end points, associated with mobile user generated traffic traversing a Core network, with the serving machine located on application provider network. The describe system/method involves early stage identification of traffic flow (i.e., at the Packet Data network Gateway device using Application Detection and Control function) and dynamically instantiating an end point for the aforementioned traffic flow at the server where the application request is being served. The traffic is then directly tunneled to the endpoint thus avoiding decapsulated mobile traffic from traversing across provider network.

This disclosure relates to the field of data communication, and provides a network congestion notification method, an agent node, and a computer device. When receiving a first data packet, an agent node adds a source queue pair number to a first data packet to obtain a second data packet, and sends the second data packet to a receive end by using a network node. In a process of forwarding the second data packet, if the network node detects network congestion, the network node generates a first congestion notification packet carrying the source queue pair number, and sends the first congestion notification packet to the agent node. Further, the agent node sends the first congestion notification packet to a transmit end, so that the transmit end decreases a sending rate of a data flow to which the first data packet belongs.

An apparatus and a method for managing network flow congestion are provided. The method for managing network flow congestion includes: receiving a plurality of packets; identifying whether each packet belongs to a predetermined protocol; distinguishing a plurality of connections of the packets belonged to the predetermined protocol; monitoring a buffer usage of each different connections; and performing a congestion check procedure on the currently monitored connection. In the congestion check procedure, when the buffer usage of the currently monitored connection exceeds a threshold, a congestion processing procedure is triggered.

A dynamic heterogeneous network for transmitting media. The network has plural sources sending signals through various links and routers to plural destinations. Upon identifying a bottleneck link the network matches actual demand rate to actual service rate. A buffer setpoint is established to accommodate the difference between the demand rate and the service rate. The network determines an epoch having a penalty for deviation from the buffer setpoint. The rate allowance is reallocated to reduce the media bottleneck.

Networks and methods are provided for use in directing retry requests for content based on intervals to retry defined by network conditions. One example method generally includes receiving, from a computing device, an application programming interface (API) request for content and determining whether the API request exceeds a predefined rate limit of API requests. The method then includes, in response to the API request exceeding the predefined rate limit, calculating a retry interval for the API request based on the predefined rate limit of API requests and a number of expected API requests for an upcoming interval, appending the retry interval to a failure notice, and transmitting the failure notice to the computing device thereby indicating to the computing device to retry the API request based on the retry interval rather than immediately or rather than at another preset interval of the computing device.

Example packet control methods and apparatus are described. One example method includes detecting a packet flow causing a congestion status change. A congestion isolation message is generated and is used to change a priority of a packet in the packet flow. The congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to at least one node.

Systems and methods of improving the functioning of a computer system by implementing an adaptive encoding network are disclosed. In some example embodiments, a computer system transmits a new encoding assignment representing an encoding of a value with a new code to a consensus server, receives an approval of the new encoding assignment from the consensus server, and, based on the receiving of the approval of the new encoding assignment from the consensus server, applies the new encoding assignment to the value in subsequent messages to one or more machines, with the applying of the new encoding assignment comprising including the new code of the new encoding assignment in the subsequent messages in association with the value.
