摘要： A channel allocation mechanism for manages bandwidth using a channel profile to assure an available channel for supporting the highest expected bandwidth request by leaving a contiguous segment available to support such requests. Configurations discussed further below define a profile for expected media types, and associate each channel with a profile designating the media types assignable on that channel. Each media type includes a service and a bitrate, thus different formats of the same service (such as SD and HD) are distinguished. Each profile specifies a media type, and each channel is associated with one or more profiles. Further, a mapping of channels to associated profiles includes a reserve designation, indicating that other (unreserved) be fully assigned before assigning the reserved channels. The reserved channels provide a contiguous block of bandwidth, so that large bandwidth requests do not encounter assignment failure from a plurality of sparsely allocated channels.

摘要： A distributed resource management mechanism allocates transmission resources by distributing the resources among a plurality of service nodes each responsible for a portion of the resources according to a hash function. A data center receives resource allocation requests from applications, such as video services applications, including a computed hash value based on the desired resource and indicative of the service node for providing the requested resource. A remote resource management client identifies the resource and computes the hash based on a request from the application, and transmits the request to a resource management server on the service node having the resource indicated by the hash, thus avoiding centralized queuing or caching of the resource requests and instead delegating to the service nodes. Service nodes may redundantly share responsibility for the resources through a root node or a cluster arrangement, providing failover if a service node becomes inoperational.
摘要翻译：分布式资源管理机制根据散列函数，通过在各个负责资源的一部分的多个服务节点之间分配资源来分配传输资源。数据中心从诸如视频服务应用程序的应用程序接收资源分配请求，包括基于所需资源的计算的散列值，并指示用于提供所请求的资源的服务节点。远程资源管理客户端根据来自应用程序的请求识别资源并计算哈希，并将该请求发送到具有由散列表示的资源的服务节点上的资源管理服务器，从而避免资源的集中排队或高速缓存请求，而是委派给服务节点。服务节点可以通过根节点或群集布置冗余地分担资源的责任，如果服务节点变得不工作，则提供故障转移。

摘要： A video server delivers video on demand (VOD) and other video services responsive to a remote selection application over an IP network from a personal communication device such as a cellphone or smartphone. The remote selection application drives a user interface of available content, and transmits a user selection request to the video delivery server via a public access network such as the Internet. The video server correlates the identity of the requesting user with a video services channel in communication with a settop box or similar device of the user, and delivers the content to the client video device for rendering. In contrast to conventional VOD where the video services request emanates from the set top box on the same communication path (QAM channel) as the downstream signals containing the VOD content, the remote selection application is independent of the client device on an HFC network.

摘要： A method, apparatus and computer program product for managing content sessions within a network is presented. The systems disclosed herein are able to detect a requirement to modify bandwidth usage within the network either proactively or reactively. In response, example embodiments apply an adaptive bit rate adjustment technique to the content sessions to adjust a data rate associated with each content session according to the requirement to modify bandwidth usage within the network. Example embodiments also then apply a quality of service adjustment technique to the content sessions to adjust a bandwidth allocation assigned between a client and server based upon the adaptive bandwidth adjustment technique. Application of the adaptive bit rate and quality of service adjustment techniques may be policy based. Example embodiments also may monitor a plurality of servers supporting content sessions, detect a failure at a first server and move content sessions to a second server.

摘要： Techniques disclosed herein include systems and methods that provide a workflow-based session manager or workflow engine for a content delivery system, such as for delivering video-on-demand, streaming audio, streaming video, etc. Such techniques increase velocity and flexibility of deploying new features and services in a video delivery system. Techniques include a session management model provides a service-oriented and workflow-based approach. As a service-oriented approach, each functional session management step can be represented as a business service. As a workflow-based solution, a sequence of steps to be performed can be defined as data. Defined as data, steps (nodes, tasks) can then be created and changed using a graphical editor. New services can be added by defining actions for the new service, and adding a node to a given session management workflow sequence. Techniques include a workflow engine that initiates session management in realtime.

摘要： A configuration as discussed herein includes a content management system. The content management system can reside in a central location or be distributed amongst multiple different locations in a network environment. In general, the content management system keeps track of configuration information for the retrieval of content. For example, the content management system identifies a presence of one or more content delivery sources in the network environment. The content management system utilizes the contact information to communicate with content delivery sources for discovery of configuration information. The configuration information can indicate: i) a respective address of the content delivery source, ii) a type of content outputted by the respective address, iii) a format of the content such as streaming data outputted by the respective address. The configuration information can be used to identify an address in which to retrieve requested content according to a desired format.

摘要： A dynamic service group discovery mapping approach avoids manual assignment of stream channels for transporting video services to the client devices that provide the video services to an end user. Client devices, such as set-top boxes, receive video services such as video on demand (VOD), switched digital video (SDV), pay-per view (PPV) and other narrowcast types of video for selective transmission. Each client device scans for visible stream channels, and sends a report indicative of visible stream channels to a dynamic mapping server. The dynamic mapping server applies aggregation rules for determining, based on the reported stream channels, which client devices are in the same service group. By receiving reports from each client device, the dynamic mapping server identifies groupings of service groups by combining sets of client devices receiving common channels, and "builds" the service groups as additional reports indicate common stream channels visible to multiple set top boxes.
摘要翻译：动态服务组发现映射方法避免手动分配用于将视频服务传送到向最终用户提供视频服务的客户端设备的流信道。诸如机顶盒的客户端设备接收诸如视频点播（VOD），交换数字视频（SDV），付费观看（PPV）和其他窄类型的视频的视频服务，用于选择性传输。每个客户端设备扫描可视流信道，并将指示可视流信道的报告发送到动态映射服务器。动态映射服务器应用聚合规则，用于根据报告的流信道确定哪个客户端设备在同一服务组中。通过从每个客户端设备接收报告，动态映射服务器通过组合接收公共信道的客户端设备来识别服务组的分组，并且通过附加报告指示多个机顶盒可见的公共流信道来“构建”服务组。
