A method for reducing Domain Name System (DNS) lookup traffic in a computer data network in a system including a router in communication with a client computer includes the steps of receiving a DNS lookup request through a web browser when the user requests to open a particular URL. The router sends the DNS lookup request for a hostname of the web server to a DNS server and receives a corresponding IP address. The router forwards the IP address to the web browser and the web browser sends a network connection request with a file transfer request to the router. The router forwards the request to the web server. The web server responds to the request by sending an HTML document for the web page. Upon receiving the HTML document, the router examines the HTML document for the URLs associated with image elements to be downloaded for display of a web page and sends one DNS lookup request for each of the distinct hostnames, regardless of how many times that distinct hostname appears in the HTML document. The router receives IP addresses, each of which corresponds to one of each of the distinct hostnames and modifies the HTML document by replacing the each of the distinct hostnames, including their recurrences, in the URLs associated with the image elements with their corresponding IP addresses.

Reducing DNS lookups

A method of notifying consumers of available content in a content distribution system. The method includes determining the existence of a content event related to content. The content event is associated with a community. A consumer who is a member of the community is notified of the content event by sending a notification to the consumer. Access to content related to the content event is provided upon request by the consumer.

Methods, systems and storage medium for providing content notification based on user communities

To reduce Domain Name System (DNS) lookup traffic in a computer data network, a client computer requests a DNS lookup. A router or other means then sends the request for a hostname of a web server to a DNS server and receives a corresponding IP address. Next, the router forwards the request to the web server. In response, the web server sends an HTML document. Upon receiving the HTML document, the router examines the document for URLs and sends one DNS lookup request for each of the distinct hostnames, regardless of how many times that distinct hostname appears in the HTML document. The router receives IP addresses, each of which corresponds to one of each of the distinct hostnames and modifies the HTML document by replacing the each of the distinct hostnames, including recurrences, in the URLs associated with the image elements with their corresponding IP addresses.

System and method for reducing DNS lookup traffic in a computer data network

Exemplary embodiments provide notification information of a telephone voicemail message over a computer and/or hybrid communications network. A table of updated voicemail subscriber message information is generated that includes voicemail subscriber identifier information and voice mailbox message status for each respective subscriber. Web-based requests (or alternate communications standards communicating the requests) are received from subscribers for voice mailbox status information. For each request from a subscriber, subscriber-specific data is retrieved from the table and a data communications notification that incorporates the retrieved information is communicated to a voice/data communications device to provide an updated voice mailbox message status.

System and method for efficient provision of a voicemail message indicator signal over a computer data network

The present invention utilizes central offices, located on the edge of a network to route requests along the edge of the network. Once an edge client receives a request for information, the edge client makes a determination as to whether the edge client can provide the information requested. If the edge client cannot provide the information requested, then the edge client determines whether a routing instruction applies which specifies a second edge client. If the routing instruction applies, then the request is routed to the second edge client.

Methods and systems for routing requests using edge network elements

A system and method for providing an indication of a telephone voicemail message over a computer network is provided. A table of updated voicemail subscriber message information is generated that includes voicemail subscriber identifier information and voice mailbox message status for each respective subscriber. Web-based requests are received from subscribers for voice mailbox status information. For each request from a subscriber, subscriber-specific data is retrieved from the table and an Internet web page incorporating the retrieved information is provided. A web page is then generated for a subscriber and downloaded over the subscriber's web browser to provide an updated voice mailbox message status. An additional embodiment is described in which a cache in the router is utilized to store updates of the voice mailbox message status.
