Method and apparatus for bandwidth aggregation for IP flow

摘要

A method and apparatus for bandwidth aggregation for an Internet protocol (IP) flow are disclosed. A sender may split IP packets on a single IP flow, and transmit the IP packets to a receiver via at least two interfaces. The sender splitting the IP packets over multiple interfaces may not send any signaling to the receiver. Alternatively, the sender may send information to the receiver for configuring distribution of the IP packets over multiple interfaces. The information may be carried on a binding update message, a binding acknowledgement message, or a binding refresh request message. The IP packets may be split and transmitted by a logical interface that sits between an IP layer and a layer 2, or by a bandwidth aggregation (BWA) middleware located between a transmission control protocol (TCP) layer and an IP layer.

主权项

1. A method for bandwidth aggregation for an Internet protocol (IP) flow, the method comprising:
a sender splitting IP packets on a single IP flow; the sender transmitting the IP packets on the single IP flow to a receiver via at least two interfaces; and the sender receiving access network discovery and selection function (ANDSF) Inter-System Routing Policy (ISRP) including a routing rule for IP flow distribution.
