CATP: A Context-Aware Transportation Protocol for HTTP

— The rendering mechanism used in Web browsers have a significant impact on the user behavior and delay tolerance of retrieval. The head-of-line blocking phenomena prevents the browser to render partial results within the HTTP document. This phenomena stems from two factors: TCP’s in-order data uploading to the browsers and HTML tag matching constraint. We propose a context-aware transportation protocol (CATP) to run on top of UDP, which allows out-of-order retrieval of HTML pages. It reorganizes the pages and transmits HTML tags first before transporting their enclosed data. Conforming browsers receive the page structures and fill them in with subsequent data packets in whatever sequence they arrive. As a result, lost and delayed packets do not hinder rendering of those that are logically behind but have already arrived at the client sides. Thus the retransmission of the lost frames can be concealed and overall user perceived performance improved. In this paper, the user-percei...
