Embodiment Construction

[0027] Combining parallel HTTP connections and pipelining has the benefit of overcoming the effect of increasing round trip time (RTT). In general, known browsers employ a fixed number of parallel connections and a fixed number of outstanding requests, although the number of parallel connections is influenced by the different sets of servers that must be contacted.

[0028] One aspect of the invention is to vary the number of parallel connections and pipeline requests in real-time so that the number of outstanding requests is minimized and the link remains fully utilized.

[0029] For example, these numbers can be varied based on the total amount of data requested to ensure that the link remains fully utilized; however, the total amount of data not yet received cannot exceed the product of bandwidth and RTT. These quantities are continuously changing. Furthermore, because the size of the object is not known until the object's header arrives, the total amount of outstanding da...

Abstract

Combining parallel Hypertext Transfer Protocol (HTTP) connections and pipelining overcomes an impact of increasing Round Trip Time (RTT) by varying in real time the number of parallel connections and pipelined requests such that the number of outstanding requests is minimal and the link remains fully utilized. Optimal construction and scheduling of requests and connections in an HTTP stack improves page load time and also provides for greater responsiveness to changes in object priorities. Multi-homing and mobility at the application layer for HTTP are addressed. Multi-homing provides for simultaneous use of multiple interfaces, for example WWAN and WLAN interfaces which improves download time, especially in the case that the available bandwidth the interfaces is of the same order of magnitude. Mobility provides for switching connections as the device moves. In combination they provide for smoother mobility. Mobility can be provided this way without server or network support.
