摘要: A method for providing error correction of media packets. Service nodes associated with a core network segment use a first error correction process, and service nodes associated with an access network segment use a second error correction process. Service nodes associated with a local network segment may use a third error correction process. The present invention utilizes different error correction processes on different network segments as appropriate. Service nodes may receive indicators from monitoring agents that error correction is insufficient and, in response, a service node may increase an amount of error correction associated with a network segment. Media packets may be interleaved in a forward error correction (FEC) block in a manner that increases an amount of packet recovery.

摘要: The present invention relates to providing monitoring agents in various elements of a switched digital media network. The monitoring agents may be placed in one or more of the following types of devices: customer premise equipment, access nodes, switching offices, hub offices, head end equipment, and the like. The monitoring agents may be located in any number of the types of devices at the same or different hierarchical levels in the switched digital media network. In different embodiments, the monitoring agents may be employed at different locations and provide various functionality, which may include capturing segments of streaming media, communicating with each other, providing and processing fault alarms, determining the location of fault alarms, or the like.
