Network bandwith 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;
setting a send-probability value in response to network traffic conditions on the traffic management server;
transmitting the send-probability value from the traffic management server to the at least one client node in a first information packet;
utilizing the send-probability value at the at least one client node to compute a randomized data transmission time;
transmitting a data packet by the at least one client node at the computed randomized data transmission time;
receiving the data packet at the traffic management server; and
generating and sending a second information packet by the traffic management server to the at least one client nodes, wherein the second information packet provides a new send-probability value for a next transmission.

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.
