    摘要: A video-on-demand (VOD) server in an Internet protocol television (IPTV) network with a network of set-top boxes includes IPTV operational data and an analysis module that selects a content item. The VOD server divides the content item into sequential chunks, divides the chunks into stripes, pre-populates set-top boxes in a peering network with at least one stripe from each chunk, receives a request for the content item, and directs each set-top box to sequentially stream its stripes. A method includes selecting a content item based upon IPTV operational data, dividing the content item into sequential chunks, dividing the chunks into stripes, pre-populating set-top boxes in a peering network with at least one stripe from each chunk, receiving a request for the content item, and directing each set-top box to sequentially stream its stripes.

    摘要: Packet routing via payload inspection at routers in a core of a distributed network for use in distributing content according to quality of service guarantees. Packets contain subjects and attributes in addition to routing information. The subjects correspond with particular types of content for subscriptions, and the attributes encapsulate the data or content. The subscriptions are associated with particular quality of service guarantees or levels of service. The routers store filters corresponding with subscriptions to content. Upon receiving a packet, a router inspects the payload section of the packet containing the attributes in order to retrieve the attributes and match them to the filters for the subscriptions. If the attributes satisfies a filter, the packet is routed to the next link in accordance with the quality of service guarantee associated with that filter. If the attributes do not satisfy any of the filters injected to and stored at the router, the router discards the packet. These routing decisions are distributed among routers in the network core.

    摘要: A method and apparatus provide for content-based routing of packets in a publish-subscribe network. A packet is received via the network. A map specifying computed filter coverage in an attribute space is accessed. Content of the packet is inspected for a routing decision for the packet. The map is used for the routing decision for the packet. The packet is routed based upon the inspected content of the packet and the map. A router for content-based routing of packets in a publish-subscribe network, comprising modules for performing this method is provided. A network including a plurality of such routers is provided. A computer-readable medium including instructions for performing this method is provided.

    摘要: Packet routing via payload inspection at routers in a core of a distributed network. Packets include subjects and attributes in addition to routing information. The subjects correspond with particular types of content for subscriptions, and the attributes encapsulate the data or content. The routers store filters corresponding with subscriptions to content. The subscriptions can include wildcards, which are converted to filters using routing rules that constrain sizes of fields for the subscription. Upon receiving a packet, a router inspects the payload section of the packet containing the attributes in order to retrieve the attributes and apply them to the filters for the subscriptions. If an attribute satisfies a filter, the packet is routed to the next link. If the attributes do not satisfy the filters, the router discards the packet. These routing decisions are distributed among routers in the network core.
