Content is dynamically assembled at the edge of the Internet, preferably on content delivery network (CDN) edge servers. A content provider leverages an “edge side include” (ESI) markup language that is used to define Web page fragments for dynamic assembly at the edge. Dynamic assembly improves site performance by caching objects that comprise dynamically-generated pages at the edge of the Internet, close to the end user. Instead of being assembled by an application/web server in a centralized data center, the application/web server sends a page template and content fragments to a CDN edge server where the page is assembled. Each content fragment can have its own cacheability profile to manage the “freshness” of the content. Once a user requests a page, the edge server examines its cache for the included fragments and assembles the page on-the-fly.

The disclosed embodiments disclose techniques for optimizing caching performance for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and cloud controllers cache portions of the distributed filesystem on hard drives with rotating disk platters. The outside portions of these disk platters have higher I/O bandwidth than the inside portions of the disk platters. During operation, a cloud controller determines that a hot subset of cached data is likely to be accessed frequently by clients, and stores this hot subset to an outside portion of a disk platter. The cloud controller further determines that a cold subset of cache data is less likely to be accessed by clients, and stores the cold subset on an inside portion of a disk platter. 1.

Принадлежит:

An enterprise voice system such as a contact centre is disclosed which provides a speech analytics capability. Whilst call recording is common in many contact centres, calls are normally recorded in single-channel audio files in order to save costs. Previous attempts to provide automatic diarization of those recorded calls have relied on training the system to recognise voiceprints of users of the system, and then comparing utterances within the recorded calls to those voiceprints in order to identify who was speaking at that time. In order to avoid the need to train the system to recognise voiceprints, an enterprise voice system is disclosed which inserts a digital watermark into the digitised audio signal from each user's microphone. By inserting the digital watermark with an energy, and, in some cases also with a spectrum, which matches the digitised audio signal, and taking advantage of typically only one user speaking at a time, a mark is left in the recorded call which a speech analytics system can use in order to identify who was speaking at different times in the conversation. 1. A method of generating a single-channel audio signal representing a multi-party conversation , said method comprising:receiving a plurality of audio signals representing the voices of respective participants in the multi-party conversation, and for at least one of the participants, marking the audio signal representing the participant's voice, at least when they are speaking, by:i) finding the current energy in the audio signal representing the participant's voice;ii) generating a speaker-dependent signal having an energy proportional to the current energy in the audio signal representing the participant's voice; andiii) adding said speaker-dependent signal to the audio signal representing the participant's voice to generate a marked audio signal;generating a single-channel audio signal by summing said at least one marked audio signal and any of said plurality of audio signals which ...
