Network bandwidth regulation using traffic scheduling
First Claim
1. A method for regulating communication network bandwidth, the method comprising:
- monitoring data traffic over a network using a centralized traffic management server, wherein the traffic management server continuously monitors a sample of incoming packets sent by at least one client node;
predicting network loads, wherein the traffic management server computes a load information based on a frequency, a rate of change, and a content of the sample of incoming packets;
scheduling network traffic, wherein the traffic management server and the at least one client node exchange a message to determine a scheduled time for an upcoming transmission of a data packet; and
transmitting data, wherein the at least one client node transmits the data packet over the network at the scheduled time.

Abstract
Disclosed herein are systems and methods for regulating network bandwidth by means of monitoring network traffic, predicting network loads, and scheduling traffic utilizing traffic reporting and bandwidth reservation mechanisms. These systems and methods may reduce network congestion and support more efficient processing by network applications. Traffic reporting may comprise broadcasting control messages to network nodes indicating appropriate times to send and receive messages. Network nodes may use traffic reports (e.g., control messages) to proactively regulate their use of the network. Bandwidth reservation may allow network nodes to do productive processing while waiting to send and receive data, and may decrease mean wait times. Reservations may be implemented in a synchronous or asynchronous manner. In an exemplary embodiment, the reservation mechanism may emulate a traditional stream socket API. Embodiments enabling enhanced TV applications to run more effectively over cable TV out-of-band networks are described.
