Method for capacity enhancement of packet switched networks

A method for enhancing capacity in a packet switched network, comprising the following steps:

• i. classifying data packets according to criterion selected from the group consisting of packet priority, smoothing, packet states and packet types;
• ii. placing said classified packets in a queue;
• and
• iii. extracting said packets from said queue.

A method for enabling data network capacity enhancement by improved management of packets in a queue, comprising the steps of:

• i. classifying the packets according to priority, by determining the individual characteristics of any individual packets;
• ii. considering a smoothing procedure so as to represent said packets fairly;
• iii. considering states of each said packet, so as to represent special events;
• iv. positioning said packets anywhere in a single physical queue.

A method for intelligent classification of data packets in packet switched networks, such that packets are intelligently classified, according to the following steps:

• i. analyzing the packets' ULP headers, said analyzing enabling defining of packet priority on a per packet basis;
• ii. analyzing queue history for a data communication session that includes the packets, such that session dynamics can be identified;
• and
• iii. analyzing session history for said data communication session, such that said session dynamics can be identified.
• iv. analyzing content-related data of the packets, such that packet states can be identified.

A method for switching queue management policies during open data transfer sessions in a packet switched network, comprising the steps of:

• i. operating a queue management policy for the network, according to a simple queue management policy mechanism, while there is low utility of data queues;
• ii. monitoring said queues to determine queue length;
• iii. monitoring said queues to determine queue growth rate;
• iv. deciding at a chosen network traffic level to implement an alternative queue management policy, based on said queue length and said queue growth criteria.

A method for switching queue management policies for open data transfer sessions in a packet switched network, comprising the steps of:

• i. operating a queue management policy for the network, according to a chosen queue management policy mechanism, while there is high utility of data queues;
• ii. monitoring said queues to determine queue length;
• iii. monitoring said queues to determine queue growth rate;
• iv. deciding at a chosen network traffic level to implement a more simple queue management policy, based on said queue length and said queue growth criteria.
