Methods and systems are provided for delivering content from a website to a computer device. The website and computer device negotiate terms for use of a cache memory coupled to the computer device. The computer device requests content, such as web page objects, from the website. In addition to transmitting the requested content, the website transmits non-requested content to the computer device. The non-requested content is stored in the cache memory for later retrieval by the computer device.

Cache on demand

A novel approach is provided for avoiding the 'slow-start restart' in TCP communications when network conditions dictate such. The disclosed approach serves to overcome the latency related to the 'slow-start restart' by assessing network conditions and avoiding the &#x201c;slow-start restart&#x201d; when network conditions justify the avoidance. The disclosed methods, applications and devices implement the periodic communication of a probe packet that is generated and transmitted from a TCP sender to a TCP receiver during the period that the TCP network connection remains idle. Receipt of the probe packet by the TCP receiver will trigger transmission of an acknowledgment message by the TCP receiver. Upon receipt of the acknowledgement message the TCP sender will restart measurement of the idleness period and, as such the &#x201c;slow-start restart&#x201d; is avoided.

Methods and applications for avoiding slow-start restart in transmission control protocol network communications

Systems and methods are provided for delivering content in a communications system. A communications system is provided that includes a plurality of terminals and a content director. The terminals are adapted to communicate via a communications network, and are each capable of requesting and thereafter receiving content via the communications network. The content director, on the other hand, is capable of receiving a request for content from one terminal. The content director can then push the content to the terminal based upon the request, and push the content to at least one other terminal before the other terminals request the content. Each terminal can have an associated user interest correlation with each other terminal. In such instances, the content director can push the content to other terminals based upon the user interest correlation of the other terminals with respect to the terminal requesting the content.
