20080205291 | SMART PRE-FETCHING FOR PEER ASSISTED ON-DEMAND MEDIA - A “Media Sharer” operates within peer-to-peer (P2P) networks to provide a dynamic peer-driven system for streaming high quality multimedia content, such as a video-on-demand (VoD) service, to participating peers while minimizing server bandwidth requirements. In general, the Media Sharer provides a peer-assisted framework wherein participating peers assist the server in delivering on-demand media content to other peers. Participating peers cooperate to provide at least the same quality media delivery service as a pure server-client media distribution. However, given this peer cooperation, many more peers can be served with relatively little increase in server bandwidth requirements. Further, each peer limits its assistance to redistributing only portions of the media content that it also receiving. Peer upload bandwidth for redistribution is determined as a function of surplus peer upload capacity and content need of neighboring peers, with earlier arriving peers uploading content to later arriving peers. | 08-28-2008 |
20090034614 | FEEDBACK ASSISTED TRANSMISSION OF MULTIPLE DESCRIPTION, FORWARD ERROR CORRECTION CODED, STREAMS IN A PEER-TO-PEER VIDEO SYSTEM - MD-FEC is considered an efficient way to generate a large number of descriptions. However, typically, MD-FEC introduces significant redundancy across streams. MD-FEC encoded streams (descriptions) are adapted based on feedback. Specifically, the bits sent in each description by a supplying peer are adapted based on the number of available descriptions in its receiving peer. The adaptive delivery eliminates unnecessary bits in the original MD-FEC streams (descriptions), and significantly reduces the consumed uplink bandwidth at supplying peers. The saved bandwidth can be used to accommodate more video sessions or for other applications. | 02-05-2009 |
20100005185 | SUBSTREAM TRADING IN A PEER TO PEER LIVE STREAMING SYSTEM - In a live video P2P system using substream trading, a peer device's video quality is generally commensurate with its upload rate. Such substream trading provides in a P2P live video streaming system provides incentives and can accommodate a variety of video coding schemes. In particular, substream trading with layered video has many desirable properties, including differentiated service, short start-up delays, synergies across peer device types, and protection against free-riders. | 01-07-2010 |
20100049867 | ON DEMAND PEER-TO-PEER VIDEO STREAMING WITH MULTIPLE DESCRIPTION CODING - A peer-to-peer novel video streaming scheme is described in which each peer stores and streams videos to the requesting client peers. Each video is encoded into multiple descriptions and each description is placed on a different node. If a serving peer disconnects in the middle of a streaming session, the system searches for a replacement peer that stores the same video description and has sufficient uplink bandwidth. Employing multiple description coding in a peer-to-peer based network improves the robustness of the distributed streaming content in the event a serving peer is lost. Video quality can be maintained in the presence of server peers being lost. The video codec design and network policies have a significant effect on the streamed video quality. The system performance generally improves as the number of descriptions M for the video increases, which implies that a higher video quality can be obtained with the same network loading. | 02-25-2010 |
20100153575 | VIEW-UPLOAD DECOUPLED PEER-TO-PEER VIDEO DISTRIBUTION SYSTEMS AND METHODS - View-upload decoupled (“VUD”) peer-to-peer (P2P) video distribution is provided, in which each peer is assigned to one or more channels to upload, with the assignments made independent of what the peer is viewing. For each assigned channel, the peer distributes (that is, uploads) the channel. This effectively creates semi-permanent distribution swarms for each channel, which are formed by peers responsible for uploading that channel. This can minimize problems associated with channel churn because peers may remain in their assigned distribution groups even if they switch channels. To minimize cross-channel overhead associated with VUD P2P video distribution, substream swarming, in which a peer in a distribution swarm only downloads a small portion of the video stream, called a substream, and uploads the substream to multiple viewers, may be provided. To minimize video streaming quality degradation that may occur during a reconfiguration transient period upon sudden and large increases in video download demands for some channel, VUD P2P video distribution may be integrated with tradition ISO P2P video distribution (which is self-adaptive to the sudden increases in channel popularity). | 06-17-2010 |

20100088405 | Determining Network Delay and CDN Deployment - Charting a content distribution system (CDN) involves identifying a set of DNS servers that may be used as vantage points to test delay performance to a CDNs content server. As provided herein, to identify potential vantage point DNS servers, a set of authoritative name servers is identified and, from that set, those authoritative name servers that respond to a DNS query are identified as responsive authoritative name servers. Identifying a CDN content server that serves a particular vantage point DNS server involves retrieving an IP address for the CDN content server from a DNS query to the DNS server corresponding to the vantage point. The delay performance between the vantage point DNS server and the CDN content server can then be determined. Further, one can determine locations to deploy new data centers for a CDN based on delay performance, A delay from one or more vantage points to an existing CDN's DNS servers can be measured, and desired rank of locations can be generated. A location of a new data center can be selected based on a desired delay performance ranking. | 04-08-2010 |
20110119370 | MEASURING NETWORK PERFORMANCE FOR CLOUD SERVICES - Described is a technology by which a content server downloads an active content measuring tool object to a client request for a page. When loaded, the measuring tool object makes network measurements, including by direct socket access, and return measurement results. As part of its operations, the measuring tool object may request measurement assignments from a central controller, and/or return those results to the central controller. Measurement assignments may be directed towards determining a round trip time/latency, measuring throughput, packet loss rate, detecting in-fight modification of content and/or detecting the presence of a middle box, including the presence of a caching proxy server middle box. The measurement results may be used to evaluate hypothetical deployment of a number of servers and/or geographic locations for those servers. | 05-19-2011 |
