Methods, apparatus and user interface for providing content on demand

Methods and apparatus for supporting content delivery service are described. In accordance with the invention content can be supplied to temporary storage of a regional or local server used to supply the content to a customer's premises when the requested content is not already available in the regional or local server. A content server hierarchy may be implemented with servers higher up in the hierarchy including more content, e.g., titles, than the number of titles stored in the lower level servers. By storing less frequently accessed content in servers higher in the hierarchy and frequently requested titles lower in the hierarchy, a vast number of titles can be supported without overburdening the storage available at local and regional servers. In addition, a national or other server high in the hierarchy can be used to store, move, and distribute local or other content as part of an on demand service.

Method and apparatus for installation abstraction in a secure content delivery system

A system for secure delivery of on-demand content over broadband access networks includes a client application executing on a user's local computer system. The client application interacts with a content server on which a plurality of selectable titles are stored and further interacts with an access server which provides the network address of a title and keying data necessary for to the client process access and execute the title. The client process utilizes an installation abstraction which enables a title to be executed on the local computer system without ever being installed. The abstraction is achieved by mounting a network file system and storing a set of registry entries related to the title on the local computer system. Portions of the title are retrieved from the content server and executed by the local operating system. During title execution, requests from the local operating system are intercepted and redirected to the set of registry entries, as applicable. The times at which the client process may retrieve the title data from the content server are defined by the access server through use of an activator and token.

Task distribution processing system and the method for subscribing computers to perform computing tasks during idle time

A computer executable "aggregate" task is processed by dividing it into subtasks and distributing the subtasks "on demand" to remotely located subscribing computers via a computer network. The aggregate task originates at a coordinating computer, coupled to one or more peripheral computers by appropriate communications links. The coordinating computer divides the aggregate task into multiple independent subtasks. Each peripheral computer begins to "subscribe" to the coordinating computer's aggregate task by obtaining an "idle time activation program" from the coordinating computer, and then installing the program locally. The idle time activation program which may include a screen saver, activates automatically when the subscribing computer is inactive. Continuing the subscription process, each peripheral computer requests a subtask from the coordinating computer. In response, the coordinating computer distributes different subtasks among the subscribing computers, completing the subscription process. The subscribing computers automatically work on their respective subtasks whenever they are idle, as directed by the local idle time activation program. When a subscribing computer completes its subtask, it transmits results back to the coordinating computer. When results of all subtasks have been received from subscribing computers, the coordinating computer compiles and stores these results, concluding the aggregate task.

Fully distributed routing over a user-configured on-demand virtual network for infrastructure-as-a-service (IaaS) on hybrid cloud networks

A layer-3 virtual router connects two or more virtual networks. Virtual networks are overlaid upon physical networks. Each virtual network (VN) is a layer-2 network that appears to expand an organization's LAN using virtual MAC addresses. The network stack forms a virtual-network packet with a virtual gateway MAC address of the virtual router to reach a remote virtual network. A VN device driver shim intercepts packets and their virtual MAC and IP addresses and encapsulates them with physical packets sent over the Internet. A VN switch table is expanded to include entries for nodes on the remote virtual network so that all nodes on both virtual networks are accessible. A copy of the VN switch table is stored on each node by a virtual network management daemon on the node. A Time-To-Live field in the virtual-network packet is decremented for each virtual hop and a checksum recalculated.

Push-Pull Based Content Delivery System

QoS is built into a peer network within existing Internet infrastructure itself lacking QoS, by enabling a network peer to continuously discern the network's ability to deliver to that peer a particular Content Object (distributed in groups of component Packages among neighboring VOD peers) within predetermined times. Content Objects are divided into groups of component Packages and distributed to Clusters of neighboring network peers, enhancing QoS upon subsequent retrieval. Tracking Files (lists of network peers storing Package groups) and Tracking Indexes (lists of network peers storing Tracking Files) are generated to facilitate “on demand” Content Objects retrieval. Dynamically monitoring network traffic (including VOD functionality, bandwidth and reliability) creates “distributed closed-loop feedback,” and in response, attributes of individual network peers (e.g., Trust Level and membership within a particular Cluster) are modified, and “content balancing” functions performed (e.g., redistribution of Package groups among network peers) enables maintaining high QoS.

System and method for recording a presentation for on-demand viewing over a computer network

A system and method for recording and playback of a live presentation that enables a reproduction of audio and visual aspects of the live presentation and enables on-demand viewing of the presentation at a later time. A live presentation comprising a plurality of presentation slides, audio content, and optionally, visual content are recorded as a data stream, so that when the recording of the data stream is played, the presentation slides are displayed in substantial synchrony with reproduced audio and visual content on a viewer's computer, thereby reproducing the live presentation. The plurality of presentation slides are saved as HTML files to a predetermined location that is accessible by the viewer's computer over a computer network, such as the Internet. During the presentation, the live audio and visual content is captured and encoded into the data stream, which is in an active streaming format (ASF), and the data stream is saved to a file. Also, slide display commands produced in conjunction with the display of the presentation slides during the presentation are interleaved into the data stream. In response to a viewer's request to view the presentation at a later time, the data stream file is downloaded to the viewer's computer and played back using a media player, which decodes the data stream file to replicate the live audio and visual content of the presentation. As the slide display commands are encountered during playback of the data stream file, corresponding HTML slide files are downloaded over the computer network to the viewer's computer and displayed so that they are substantially synchronized with the reproduced audio and visual content of the presentation.

Virtual machine migration

A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. The source VM memory is either paged in to the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. The source and destination servers preferably share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents. Network connectivity is preferably also made transparent to the user by arranging the servers on a common subnet, with virtual network connection addresses generated from a common name space of physical addresses.

Methods, systems, computer program products, and methods of doing business by using dynamic capacity-on-demand techniques for re-routing traffic in a distributed computing network. When demand on an enterprise's resources exceeds some predetermined level, dynamic modifications cause static content (such as images) to be served from resources which are external to the enterprise, such as a caching system which is located close to the enterprise's end users. When demand falls below the predetermined level, the modifications are effectively reversed, such that the external resources are no longer used. The predetermined level may apply to a single monitored device, or to a group of monitored devices. The dynamic capacity-on-demand techniques may also be used for dynamic types of content, such as for dynamically re-routing access to an application program executing on an external resource, and may be used for internal capacity-on-demand as well.

Method and system for HTTP-based stream delivery

A method of delivering a live stream is implemented within a content delivery network (CDN) and includes the high level functions of recording the stream using a recording tier, and playing the stream using a player tier. The step of recording the stream includes a set of sub-steps that begins when the stream is received at a CDN entry point in a source format. The stream is then converted into an intermediate format (IF), which is an internal format for delivering the stream within the CDN and comprises a stream manifest, a set of one or more fragment indexes (FI), and a set of IF fragments. The player process begins when a requesting client is associated with a CDN HTTP proxy. In response to receipt at the HTTP proxy of a request for the stream or a portion thereof, the HTTP proxy retrieves (either from the archive or the data store) the stream manifest and at least one fragment index. Using the fragment index, the IF fragments are retrieved to the HTTP proxy, converted to a target format, and then served in response to the client request. The source format may be the same or different from the target format. Preferably, all fragments are accessed, cached and served by the HTTP proxy via HTTP. In another embodiment, a method of delivering a stream on-demand (VOD) uses a translation tier (in lieu of the recording tier) to manage the creation and / or handling of the IF components.

Versioning synchronization for mass p2p file sharing

A “Mass File Sharer” (MFS) provides a mass P2P file sharing protocol with optional on-demand file access across a P2P network. Unlike conventional P2P file sharing, the MFS simultaneously asynchronously shares large numbers of files, while providing optional on-demand (synchronous) access to shared files. The MFS uses a unique metadata structure in combination with an inter-peer file / folder version analysis and an inter-peer file / folder availability analysis to share complex directory structures that may include any number of folders, sub-folders, and files. Sharing may be asynchronous and / or synchronous. Specifically, file sharing is generally accomplished as an asynchronous distribution across the network. However, when a particular peer wants direct access particular files, an on-demand access mode is used to enable synchronous delivery of shared files. This combination of asynchronous and synchronous file distribution enables the MFS to support a number of applications, such as on-demand movie viewing, file / folder browsing, etc.

Method and apparatus for identifying problems in computer networks

A network appliance for monitoring, diagnosing and documenting problems among a plurality of devices and processes (objects) coupled to a computer network utilizes periodic polling and collection of object-generated trap data to monitor the status of objects on the computer network. The status of a multitude of objects is maintained in memory utilizing virtual state machines which contain a small amount of persistent data but which are modeled after one of a plurality of finite state machines. The memory further maintains dependency data related to each object which identifies parent / child relationships with other objects at the same or different layers of the OSI network protocol model. A decision engine verifies through on-demand polling that a device is down. A root cause analysis module utilizes status and dependency data to locate the highest object in the parent / child relationship tree that is affected to determine the root cause of a problem. Once a problem has been verified, a “case” is opened and notification alerts may be sent out to one or more devices. A user interface allows all objects within the network to be displayed with their respective status and their respective parent / child dependency objects in various formats.

On-demand data system

Disclosed is a system for allowing on-demand delivery of data, such as MPEG-2 compressed video data, to a subscriber from a content server. The system utilizes a managed IP network that is coupled to the one or more content servers that allows the content servers to deliver data such as video, audio, and textual data with a guaranteed quality of service that is at least as good as broadcast quality service. The managed IP network is connected to a head end or other local cable service provider where video is delivered locally to subscribers. The IP transport data is translated to MPEG transport data, multiplexed onto an MPEG transport system, digitally modulated onto an rf carrier and up-converted to a specific frequency channel. The signal is then applied to the cable for delivery to the subscriber. Upstream signaling occurs through a set top box or computer that is connected to the cable and subsequently to a digital modulator / demodulator and ISP to a managed IP network 66. Low band signals can also be transmitted from the content servers back to the set top box or computer indicating confirmation of an order. Also, control signals such as stop, rewind, fast-forward, and slow can be transmitted back to the content server to control the transmission of data from the content server to the subscriber.
