摘要： A data rate management system that provides quality of service at the fine granularity of applications in the home network and home automation environment is provided. An application can be associated with a dynamic traffic flow, a physical port, a logical interface, or a host computer or device. Virtual queueing is applied to isolate and protect individual applications. Comprehensive rate management algorithms are developed to offer the bandwidth guarantee for the applications individually. The data rate management system includes a traffic classifier, virtual queueing, and a rate manager. The traffic classifier can statically or dynamically identify an application. The identified application is stored in a dedicated virtual queue. The rate manager schedules the packet transmission among virtual queues using the application-based traffic profiles.

摘要： 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.
