INTRODUCTION

 We provides to the client download/upload

manager which will have the option to delay certain downloads/uploads.

 Client revenue: will be rewarded by lowering

package usage.

 OSAS will be synchronized with an intended

server that will have a clients tasks queue, dependent on clients demands and order of demands.

 OSAS will automatically detect network loads

and will schedule downloads/uploads according to current load, balancing network traffic.

OBJECTIVES

 Manage downloads/uploads and connect to the

company’s scheduler.

 Manage the queuing server that will

control the traffic of downloads/uploads.

 Notify download/upload managers connected to it

to start/resume transfers.

FEATURES

 The server application side:

 Add / Remove download/upload.  Force download/upload to complete (in cases customer

doesn’t want to wait anymore).

 Automatically detect loads and congestion.  Synchronize with current loads.  Fair queuing – clients with earlier requests will be prior to

later requests (all depend also on customer deadline and traffic limitation).

 Client application side:

 Gives the client to chose when download/upload  Gives the client option to not use the service when he don’t

want it

 Raises awareness about the network overloading

METHODOLOGY

 Server side:  Establish a protocol for the queuing of requests  Use existing congestion sensors/detector as an input

to dynamically control downloads/uploads in terms of speed in real-time.

 Client side:  Create a user friendly application that will integrate

to client’s smartphone and be connected to company’s server.
