Abstract: Recognition of users by assigned source port blocks identifies a specific network-attached device using date, time, WAN IP, and source port information associated with a user session. The method includes the steps of: receiving a date, time, WAN IP address, and source port associated with a user session; a computer searching a list of user sessions for one or more LAN IP addresses associated with the received WAN IP address that were in use at the received date and time; responsive to finding one or more matching IP addresses, a computer searching a list of assigned source ports for a match between a set of source ports assigned with the found LAN IP addresses and the received source port; and responsive to finding a matching source port, a computer identifying a source host device that is assigned the matching LAN IP address.

Abstract: A system and method for messaging and obtaining message acknowledgement on a limited-area network managed by a network management device connected to a wide-area network. The system allows messages to target individual end user devices and receive message acknowledgement from end users. The method allows the recipient of an individually targeted message to prevent service interruption or to be rewarded by acknowledging receipt of a message.

Abstract: A system, method, and computer readable medium for preventing denial of service attacks in a cellular network, that comprises, counting a data packet generated by an address on the cellular network and blocking access to the cellular network of the address if the counted data packets exceeds a pre-defined threshold.

Abstract: A system, method, and computer readable medium for preventing denial of service attacks in a network, comprising counting a data packet generated by an address on the network and blocking access to the network of the address if the counted data packets exceeds a pre-defined threshold. In other embodiments, the counting may per performed per time unit, the blocking may be active for a pre-set interval, the address may be disabled, the address may be a media access control address, the counting could be performed at layer 2 or layer 1, the address may be identified upon connection to the network, the threshold may be based upon a number of computers utilizing the network, the defined threshold may be based upon a bandwidth of the network and the disinfecting may be done of the address exceeding the pre-defined threshold.
