Filed:

May 21, 2007

Appl. No.:

11/804876

Inventors:

Albert Lee - Aliso Viejo CA, US
Mahadevan Iyer - Thane, IN

International Classification:

H04J 1/16
H04J 3/22
H04L 12/56

US Classification:

370252000, 370465000, 370389000

Abstract:

A plurality of network characteristics of a wireless network are determined and a plurality of TCP session parameters are updated. The network characteristics may be determined based at least in part on a comparison of the estimated bandwidth and estimated propagation delay of the wireless network and the typical bandwidths and propagation delays of one or more wireless networks. The TCP session parameters may be updated based at least in part on the network characteristics. The TCP session parameters may be used to limit the congestion window, retransmission timeout and slow start threshold.

Mahadevan Iyer - Thane, IN

International Classification:

H04L 12/56

US Classification:

370395520

Abstract:

During a Transmission Control Protocol (TCP) session, a congestion window and slow start threshold may be limited to a range defined by a minimum congestion window and a maximum congestion window based at least in part on the network type of a wireless network. The network type of a wireless network may be determined based in part on one or more round trip times of one or more data segments and one or more TCP session parameters are set to corresponding stored session parameters that are associated with the network type.

Inventors:

Albert Lee - Aliso Viejo CA, US
Mahadevan Iyer - Thane, IN

International Classification:

H04J 3/22
H04J 3/18

US Classification:

370468000, 370477000

Abstract:

An inter-departure time of a pair of TCP segments, or a mean inter-departure time of a block of TCP segments, is determined and an inter-arrival time of a pair of non-duplicate acknowledgments is determined. The bandwidth of a data network may be estimated based at least in part on the inter-arrival time if the inter-arrival time is not less than the inter-departure time or the mean inter-departure time.

Inventors:

Albert Lee - Aliso Viejo CA, US
Mahadevan Kulathu Iyer - Thane, IN

International Classification:

H04L 12/56

US Classification:

370389

Abstract:

A retransmission timer of a Transmission Control Protocol (TCP) session is set based at least in part on the predicted mean round trip time differential of the TCP session. For example, in one embodiment, after receiving a non-duplicate acknowledgment, the predicted mean round trip time differential of the TCP session would be determined and used to further determine the predicted round trip time of the next transmitted data segment. In one embodiment, the predicted round trip time of the next transmitted data segment would be used to determine a retransmission timeout, the value of which would be inserted into a retransmission timer.

International Classification:

G06F 15/16

US Classification:

709217, 709227

Abstract:

There is provided a module for implementing handoff and/or quality optimization of a network protocol stack (). The module is transparent to the network protocol stack () and an application () using the network protocol stack (). The module includes session detector () and an auxiliary manager (). The module may further include a request interceptor (), a request analyzer () and controller (). The session detector () detects an original session from a host to a remote host. The auxiliary session manager () opens and manages a plurality of auxiliary sessions to support the original session. The request interceptor () detects an original request issued by the application, wherein the original request is for retrieving certain content. The request analyzer () analyzes the intercepted original request. The controller () uses the original session and auxiliary sessions to retrieve the content based on the result of the analysis.
