Problems solved by technology

These frequent client interactions (the number of which increase in proportion to the number of "buddies" each logged-on user includes on their individual lists) place a heavy burden on server applications fulfilling these requests and the sub-networks that host them.

Embodiment Construction

: with 10,000 registered users each including 5 buddies on their list, the polling system employs 5,066 server hits per minute (a server hit is defined as an interaction with the server). Example 2: with 10,000 registered users each including 15 buddies on their lists, the polling system employs 15,066 server hits per minute. Example 3: with 1,000,000 registered users each including 5 buddies on their lists, the polling system employs 506,666 server hits per minute. Example 4: with 1,000,000 registered users each with 15 buddies on their lists, the polling system employs 1,506,666 server hits per minute. As these examples illustrate, the burden on the polled server increases significantly with either an increase in the number of buddies each user includes on their list or an increase in the total number of registered users.

Abstract

A method for distributing and maintaining network presence information is presented. According to an embodiment of the present invention, a user logs onto the Internet and transmits to an Internet Presence Information Server (IPIS) his / her presence information, a list of peers (individual network users) whose network presence are of interest to the user, and a request for a list of peers interested in the user's network presence. The IPIS then responds to the user with both a list including the last known Internet Protocol (IP) address for each peer the user is interested in and a list of peers interested in the user's Internet presence. No further communication between the user and IPIS is required after the IPIS responds to the user with these two lists. The user then attempts to directly contact the peers on the first list received from the IPIS by confirming and authenticating the received IP addresses. According to policy, the user directly contacts the peers on the second list received from the IPIS to inform those peers the user is currently signed on-line. Finally, the user periodically "pings" (directly contacts) the confirmed and authenticated IP addresses from the first list received from the IPIS to determine when those peers sign off-line.

Description

[0001] 1. Field[0002] The present invention pertains to distributing and maintaining network presence information. More particularly, the present invention pertains to a server assisted peer-to-peer network communication method for determining when a person, device or service is present on a network.[0003] 2. Background Information[0004] A network may be defined as a group of connected computers that allows people to share information and equipment. For example, a client / server network may consist of one or more client computers connected to a central computer known as a server. People (also referred to herein as "peers," "network users," or "Internet users") may access files stored on the server by using one of the client computers to send a message to the server. In addition to allowing network users to access files stored on central computers, current network technology (such as the Internet) permits an exchange of information between people who are simultaneously present on the ...
