Filed:

Nov 23, 1998

Appl. No.:

09/198090

Inventors:

Guy Riddle - Los Gatos CA
Robert L. Packer - Los Gatos CA

Assignee:

Packeteer, Inc. - Cupertino CA

International Classification:

G06F 15173

US Classification:

709224, 709223, 709230, 709238, 709242, 370230, 370235, 370252, 370355, 370356

Abstract:

In a packet communication environment, a method is provided for automatically classifying packet flows for use in allocating bandwidth resources by a rule of assignment of a service level. The method comprises applying individual instances of traffic classification paradigms to packet network flows based on selectable information obtained from a plurality of layers of a multi-layered communication protocol in order to define a characteristic class, then mapping the flow to the defined traffic class. It is useful to note that the automatic classification is sufficiently robust to classify a complete enumeration of the possible traffic.

International Classification:

H04J 316

US Classification:

370466, 370229

Abstract:

In a packet telecommunications environment, a method is provided for end to end explicit rate control through a plurality of heterogeneous internetworked networking topologies comprising networks without explicit rate signaling, such as TCP/IP based LAN subnets, and networks with explicit network layer rate signaling, such as Frame Relay permanent or switched virtual circuits (PVC/SVC) or ATM available bit rate (ABR) services by reallocating bandwidth in a partition using a Committed Information Rate of the portion comprising the virtual circuits for a partition size. In specific embodiments, the invention may exist as an integrated device, such as an enhanced FRAD, or a bandwidth management device, which detects congested network conditions from information obtained indirectly from a FRAD or network edge device using techniques such as reading the network edge devices MIB.

International Classification:

Abstract:

In packet communication, a method for automatically classifying packet flows for use in allocating bandwidth resources and the like by a rule of assignment of a service level. By rendering discoverable the attributes of a flow specification for packet flows, a finer grained hierarchy of classification is provided automatically that is based on information which is specific to the type of program or application supported by the flow and thus allowing greater flexibility in control over different flows within the same application. The method comprises applying individual instances of traffic classification paradigms to packet network flows based on selectable information obtained from a plurality of layers to define a characteristic class, then mapping the flow to the defined traffic class. The flow specification is provided with some application-specific attributes, some of which are discoverable. The discoverable attributes lead to an ability to automatically create sub-nodes of nodes for finer-grained control.

International Classification:

H04L012/26

US Classification:

370231, 370232, 370235

Abstract:

A method for explicit data rate control is introduced into a packet communication environment () which does not have data rate supervision by adding latency to the acknowledgment (ACK) packet and by adjusting the size of the flow control window associated with the packet in order to directly control the data rate of the source data at the station (or ) originating the packet.

Assignee:

Packeteer, Inc. - Cupertino CA

International Classification:

H04L 1226

US Classification:

370235

Abstract:

A method is provided for optimally setting the receiver window size in a flow controlled protocol in order to minimize queuing in a packet telecommunications network. Embodiments according to the present invention are operable at an explicit path to identify per connection information from host address or physical interface, flow direction, or any combination of these elements. The present invention may function in conjunction with a rate detection method that determines both a message serialization delay component and a data size invariant delay component.
