摘要： Embodiments seek to improve web page loading time using server-machine-driven hint generation for based on client-machine-driven feedback. For example, client computers having page renderers are in communication with content servers and hinting processors. The hinting processors can use hinting feedback from multiple page rendering instances to automatically generate hints for optimizing loading and/or rendering of those pages. In some implementations, in response to page requests from the page renderers, content servers can request hints from hinting processors and send those hints to the requesting page renderers for use in improving the page loading experience. In other implementations, in response to page requests from the page renderers, content servers can instruct the requesting page renderers to contact an appropriate hinting processor and to retrieve appropriate hints therefrom for use in improving the page loading experience.

摘要： Embodiments seek to improve prefetch hinting by using automated browsing clusters to generate and update hinting models used for machine-generated hints. For example, hinting machines can include browsing clusters that autonomously fetch web pages in response to update triggers (e.g., client web page requests, scheduled web crawling, etc.) and generate timing and/or other hinting-related feedback relating to which resources were used to load the fetched web pages. The hinting machines can use the hinting feedback to generate and/or update hinting models, which can be used for machine-generation of hints. Some embodiments can provide preliminary hinting functionality in response to client hinting requests, for example, when hinting models for a requested page are insufficient (e.g., unavailable, outdated, etc.). For example, without having a sufficient hinting model in place, the hinting machine can fetch the page to generate preliminary hinting feedback, which it can use to machine-generate preliminary hints.

摘要： Systems and methods are described for avoiding redundant data transfers using delta coding techniques when reliably and opportunistically communicating data to multiple user systems. According to embodiments, user systems track received block sequences for locally stored content blocks. An intermediate server intercepts content requests between user systems and target hosts, and deterministically chucks and fingerprints content data received in response to those requests. A fingerprint of a received content block is communicated to the requesting user system, and the user system determines based on the fingerprint whether the corresponding content block matches a content block that is already locally stored. If so, the user system returns a set of fingerprints representing a sequence of next content blocks that were previously stored after the matching content block. The intermediate server can then send only those content data blocks that are not already locally stored at the user system according to the returned set of fingerprints.

摘要： Systems and methods are described for subscriber-driven resource shifting in an attempt to maximize delivery of requested content to subscribers while minimizing the impact of satisfying those requests to network infrastructure resources. For example, when a media plan subscriber requests access to media content under the media plan, a determination is made that the media can be delivered at an earlier timeframe for a particular cost or at a later timeframe for a lower cost. Accordingly, an offer is presented to the requesting subscriber either to receive the media in the earlier timeframe at a higher cost, or to receive the media at a later timeframe in exchange for a discount (e.g., watch now for $4.99 or in 24 hours for free). Embodiments further handle delayed delivery of the content, notification of the delayed delivery to the subscriber, accounting for the delayed delivery, and/or other related functions.
