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 present invention relates to collecting information for networked directories. In one implementation, a method for gathering information for a directory on a packet-switched network is disclosed. In one measure, a directory of the first web site is determined. The directory is reported to the second web site for the first time. After detecting changes in the first web site, the directory is updated according to the changes. The directory is reported to the second web site a second time.

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 electronic directories, and more particularly to collecting information for networked directories. Background technique [0003] On the Internet, electronic catalogs are required so that information can be searched. Conventional directories search the entire Internet by "crawling" link by link and cataloging the information encountered. These browsing software robots or "browsers" are constantly traversing the Internet in an attempt to keep directory information up to date. Going through the Internet can take months at a time. [0004] Many electronic catalogs have browsers associated with them, which are used to collect information all over the Internet. When the browser encounters the information, it is passed back to the electronic catalog for cataloging. Thus, the browser consumes a large amount of ban...
