Definitions

  • the invention relates to maintaining information for a networked directory.
  • a method for updating a networked directory of content objects is disclosed.
  • a first catalog of first content objects associated with a first server is received.
  • the first catalog is stored in an information store.
  • a second catalog of second content objects associated with a second server is received.
  • the second catalog is stored in the information store.
  • a first elapsed time associated with the first server is detected.
  • the first catalog is tagged for deletion from the information store in response to the detecting the first elapsed time.
  • Fig. 3 A is a block diagram of an embodiment of an origin server portion of the content distribution system
  • Fig. 9 is a flow diagram of a viewer object proxy background application
  • Fig. 10 is a flow diagram of a viewer object proxy request servicing
  • the content distribution system 100 includes an active directory 104, one or more origin servers 108, one or more client computers 112, one or more content exchanges 116, one or more external origin servers 118, the Internet 120 and a crawling directory 124.
  • a particular client computer 112 interacts with the active directory 104 to select a content object for download.
  • the object can be played during download if it is streaming media or can be stored for a later time.
  • the content object could be any type of information, such as audio, video or data, that is available for download from a network.
  • the request for the content object is forwarded to the appropriate origin server 108 along with preference information from the client computer 112.
  • the origin server 108 provides the source of a content object, directs a user to a preferred source of the content object and provides directory information to the active directory 104.
  • Content objects are introduced to the system 100 by origin servers 108. Introduction involves selection by an origin server administrator of the content objects to make available to the active directory 104. The administrator is person or system that manages the origin server 108. The content objects could include previously stored information or a streaming feed of information.
  • the origin server 108 provides a catalog of the selected information that is updated as the content on the origin server 108 changes. The origin server 108 determines the preferred source to direct the client computer 112 to in order to download the content object.
  • FIG. 2 a block diagram of an embodiment of an active directory portion 104 of the content distribution system 100 is shown. Included in the active directory 104 are a dynamic domain name server (DNS) 204, a server manager 208, a directory page 212, a search page 216, a download page 220, a subscriber database 224, a server database 228, a content exchange database 232, and a route database 234.
  • DNS dynamic domain name server
  • the content distribution system 100 interacts with the active directory 104 to provide directory information to the user and assist in downloading a content object to the user.
  • the search or directory page 212, 216 presents links for each of the content objects that the user might select in step 716.
  • Each link includes the origin server name 108, port, path and name for the content object. Given the choices available, the user may select one of the links conesponding to the desired content object in step 720.
  • the dynamic DNS 204 is queried by the viewer object proxy 504 to determine the IP address of the origin server name from the link. Once the IP address is known, the content processing program is redirected to the IP address retrieved from the dynamic DNS 204 and the path and filename from the link.
  • the content processing program 508 is redirected to the chosen content store 412 and processing continues in step 744 of Fig. 7B.
  • the content processing program 508 requests the content object in the link from the content store 412 in step 744. If the whole content object is in the content store 412, the object is downloaded from that content store 412 to the client computer in steps 748 and 752.
  • the missing portions are retrieved from each content exchange 116 in step 764 until the whole content object is in the content store 412. If no other content exchange 116 has the missing portion of the content object, a query is made to the origin server 108 for the missing portion, in step 768.
  • the dynamic DNS 204 is queried to determine the IP address of the origin server name for the content object.
  • the content controller 408 is directed to the origin server 108 with the content object in step 772 by the dynamic DNS 204.
  • the missing portion is downloaded from the content server 308 of that origin server 108 in step 776. Processing loops back to step 748 to retrieve any other missing portions.
  • the decompression function 860 and the decryption function 862 are provided. These functions 860, 862 provide capability to decompress and decrypt information received from either an origin server 108, a content exchange 116, an external origin server 118, or any other server on the Internet 120.
  • the viewer object proxy 504 includes the security function 864.
  • the security function 864 operates to permit or deny access when appropriate. More specifically, the security function 864 provides control such that content objects will be decrypted only if authority is given by a trusted system. For example, a trusted system may only provide authority to accept and or decrypt data where a specific dongle type hardware device is attached to the client computer 112 and the attachment condition is reported by the security function 864 via the viewer object proxy 504.
  • the viewer object proxy 504 includes the electronic commerce function 866.
  • the electronic commerce function 866 can be integrated tightly with an electronic commerce engine resident on the Internet 120.
  • users are provided a mechanism for purchasing content objects. For example, token credits stored in the subscriber database 224 could be credited to origin servers 108 to download content objects.
  • the viewer object proxy 504 can include the standard web access function 858 which provides access to Internet domains residing outside of the content distribution system 100.
  • the standard web access function 858 determines if the content object was previously saved on the client computer 112.
  • setup 982 is performed at startup 980 and the display routine 854 is launched.
  • the setup 982 can include requesting and initializing graphics memory in the client computer 112, initializing a proxy, and launching the display routine 854. Further, setup 982 may include any processes for initializing a graphics display or a proxy.
  • Traceroute includes any analysis which returns a route that packets take between a particular content exchange 116 and the client computer 112. Typically, traceroute returns the number of hops traversed, the IP addresses of traversed hops, and the time required by a traverse between the client computer 112 and the content exchange 116.
  • Bandwidth test via file transfer includes any analysis where a bulk information transfer is performed between the content exchange 116 and the client computer 112. During the bulk transfer, various indices of performance are derived including, but not limited to, the time required to perform the bulk transfer. Typically, data transferred between the content exchange 116 and the client computer 112 is highly random. The random nature of the data reduces the impact of any compression occurring between the client computer 112 and the content exchange 116. Ping includes any analysis where information is sent by the client computer 112 to a particular content exchange 116 and the client computer 112 awaits a response from the content exchange 116. Typically, ping is performed via UDP or any other lossy protocol (i.e. a protocol which does not guarantee a response). Ping is useful to verify whether the content exchange is operational. Alternatively, the time required to receive the reply can be used as an indication of QOS.
  • content exchanges 116 included in the preference information 512 can be analyzed by path QOS evaluation 986 along with other content exchanges 116 that have been added to the content exchange database 232 since the last creation of the preference information 512.
  • experience of the viewer object proxy 504 can be used to effectuate a more efficient path QOS evaluation 986.
  • the preceding embodiments are merely illustrative and that many algorithms exist for selecting content exchanges 116 to increase efficiency of path QOS evaluation 986.
  • prior operation of path QOS evaluation 986 may have returned sufficiently poor results for a particular content exchange 116, that it is never again analyzed, but rather presumptively rejected. In some embodiments, this presumptive rejection can be manually overridden by the user.
