摘要： Methods, systems and apparatus for reducing apparent latency in content-delivery networks are provided. Sources multicast certain ‘preview multicast streams’ to multiple subscribers. These preview multicast streams provide pre-recorded content of multicast streams. When a subscriber switches to a desired multicast stream, pre-recorded content of the desired multicast stream is reconstructed from a preview multicast stream. Thereafter, the pre-recorded content is played during the setup of the new multicast distribution tree to minimize latency. Once the distribution tree is setup, live content of the desired multicast stream is made available to the subscriber.

摘要： In a packet switch with databases (250, 404) used for packet forwarding, the database pieces are identified by version identifiers (410V) which are used by the packet switch's modules (LCx, RPM0, RPM1) in exchanging information on the databases and requesting updates to the databases. For example, if a primary management module fails and the management is transferred to a secondary management module, the secondary management module requests forwarding modules (e.g. line cards) to identify the database pieces stored on the forwarding modules, and to update the databases as needed. Use of version identifiers reduces the amount of data that has to be transferred in connection with such requests.

摘要： A method and system for determining path maximum transfer unit (PMTU) in an Internet Protocol (IP) multicast is described. If a packet of a size greater than the MTU of any link of a path, with its Don't Fragment (DF) bit set, is sent by the source, the packet is dropped and an ICMP message, stating “Destination unreachable, DF bit set”, is sent to the source. The rate of messages to the source is controlled to avoid implosion of traffic. In response to the messages, the source sends multicast probe packets of multiple sizes to multicast distribution tree to determine its PMTU.

The network orchestration service provides a Border Gateway Protocol (BGP) listener module and a topology builder module. The BGP listener module is configured to receive information from a plurality of spine devices configured as an autonomous system and the topology builder module is configured to use the information received by the BGP listener module to create a topology of a data center that includes the plurality of spine devices. Additionally, the network orchestration service is in communication with a memory that is used to store information received by the BGP listener module and the topology of the data center. Applications of the information handling system for better operating the data center are also provided.
