Problems solved by technology

Unfortunately, the Internet is a poor network for this type of broadcast because: there is a loss of data quality for each of the many possible retransmissions; most transmissions have bandwidth constraints; and the Internet cannot stream data at a constant data rate

other Embodiment approach

[0033] Other implementations may have multiple Active Directories. Users of the system can be divided among multiple active directories in order to distribute the load. Additionally, other Active Directories can be used redundantly so that if one Active Directory goes offline, the other Active Directory can absorb the load.

[0034] In some implementations, the origin server 108 provides sources of content objects, directs users to preferred sources of content objects, and provides directory information to the active directory 104 . The origin server 108 introduces content objects to the system 100 . Introduction involves selection by an origin server administrator of content objects to be made available to Active Directory 104 . A manager may be a person or system that manages origin server 108 . A content object may include previously stored information or a streaming feed of information. On a predetermined basis, origin server 108 provides a catalog of selected informat...

[0093] Other embodiments may transmit metadata in any type of data channel, not just through HTTP headers. For example, metadata can travel through dedicated ports, IP addresses, URLs, headers, or other logical channels.

[0094] Preference information 512 is the result of network analysis performed from the perspective of client computer 112 . When a content object is requested, preference information 512 is passed to content object manager 312, which in turn selects an appropriate content exchange 116 for client computer 112. The preference information 512 may be updated periodically (eg, every hour) by automatic testing or manually by the user. Subsequent tests take into account previous results in order to efficiently consider preferred content exchanges. For example, a first analysis may examine 100 content exchanges, while subsequent analyzes may exclude poorer performing content exchanges so that only 50 are analyzed.

[0095] Preference information 512 includes a li...

Abstract

The invention relates to tracking content objects when distributing content on a network. One embodiment of the invention reports status information from a plurality of content exchanges to a remote location and includes a first and second content exchanges, a remote server, and a first and second datalinks. The first content exchange includes a first plurality of content object portions and the second content exchange includes a second plurality of content object portions. The remote server includes a first subset of the first plurality of content object portions and a second subset of the second plurality of content object portions. The first datalink transports a first catalog of the first subset between the first content exchange and the server and the second datalink transports a second catalog of the second subset between the second content exchange and the server.

Description

[0001] This application benefits from US Provisional Application No. 60 / 209,007, filed June 1,2000. technical field [0002] The present invention relates generally to content distribution, and more particularly to tracking content objects as content is distributed over the Internet. Background technique [0003] In order to provide sufficient QOS, it is required to deliver large content objects of high quality at a constant minimum rate. A live video broadcast is a good example of a large content object delivered at a constant minimum rate. Unfortunately, the Internet is a poor network for this type of broadcast because: there is a loss of data quality for each of the many possible retransmissions; most transmissions have bandwidth constraints; and the Internet cannot stream data at a constant data rate. [0004] As mentioned above, transferring large objects at a constant data rate without loss of information is problematic. To address these concerns, the streaming medi...
