A system and method for managing e-mail traffic originating from a specific IP address. An outbound e-mail message is routed to an e-mail governor where the IP address of the computer from which outbound e-mail message originated is determined. A record associated with the originating IP address is created in a datatstore. Metrics useful to determine an e-mail message rate and an e-mail byte rate are stored in the e-mail record. An e-mail message rate is determined and compared with an e-mail message rate threshold. If the e-mail message rate threshold is exceeded, the originating IP address is sending spam e-mail (spam) and redial action is taken. An e-mail byte rate is also determined and compared with an e-mail byte rate threshold. If the e-mail byte rate threshold is exceeded, the originating IP address is using excess network resources to send e-mail and redial action is taken.

Methods and systems for thwarting denial of service attacks originating in a DOCSIS-compliant cable network (DCN) are described. A DCN comprises one or more sub-networks each comprising an access network, one or more cable modem termination systems (CMTSs) and one or more cable modems (CMs). The DCN also accesses an edge server and a local DNS cache server. The DCN interfaces with the Internet and accesses a remote DNS server according to well-known protocols. The CMTS is adapted to compare the source IP address included in IP packet headers to the IP address of the customer premises equipment (CPE) from which the IP packet originates as assigned by the DNS. Data packets that have spoofed addresses are either deleted or quarantined. Packets reaching the edge server are evaluated by an attack detection system. A packet determined to be part of a denial of service attack is inspected and the source IP address and the destination IP address extracted.

Methods and apparatus for supporting electronic promotions and electronic requests for information, e. g. , in an integrated manner, on multiple platforms including, e. g. , cable network systems, cell phones, etc. , are described. Rewards and/or benefits are tracked in a centralized manner and a subscriber is allowed to accumulate rewards and benefits in a single account irrespective of which device or platform was used to initiate an eRFI and/or to act upon a promotion. The methods and apparatus of the present invention allow a cable service provider which supports eRFI on set top boxes to use the same eRFI server to provide responses to eRFI requests received from devices, e. g. , cell phones and/or E-mail devices corresponding to a service subscriber, to forward electronic promotion information and to reward users in a forwarding chain for redemptions of coupons included in forwarded promotion information. Forwarded promotion information securely identifies each device/user in the forwarding chain.

Systems and methods for Wi-Fi roaming. A gateway supports both a local access point (AP) and a virtual AP. The local AP is accessible only to an “owner” of the gateway. The virtual AP (VAP) is accessible to devices associated with the owner of the gateway and to roaming Wi-Fi devices. A datastore conveys information about the roaming Wi-Fi devices to the VAP to permit them to access the VAP without the need for manual configuration of the VAP. A roaming Wi-Fi device may communicate with a gateway via a tunnel to maintain session connectivity during roaming. A session may be initiated on one network, such as a Wi-Fi network or a cellular network, handed off to another network, such as a cellular network or a Wi-Fi network, and then returned to network on which the session was initiated.

Systems and methods for cloning a Wi-Fi access point. A determination is made by a network monitoring device to transition communications between a Wi-Fi device and a first access point (AP) to a second AP. The SSID and the security configuration information, and, optionally, network address translation (NAT) information of the first access point are acquired and provided to a second AP. The second AP instantiates the SSID and the security configuration information and, optionally, the NAT information. The networking monitoring device directs the first AP to cease using the SSID and the security configuration information and, optionally, the NAT information in response to receipt of confirmation that the second AP has instantiated the SSID and the security configuration information and, optionally, the NAT information of the first AP.

Systems and methods for using ad hoc networks in cooperation with service provider networks. Multi-network devices communicate with each other as peers in an ad hoc network while each accessing a service provider network. The multi-network devices may each receive the same real-time multimedia stream, be it broadcast or unicast, while sharing stream parity information. The peers may take corrective action to maintain uninterrupted playback of the real-time multimedia stream with no or minimal loss in perceived quality. The peers may further cooperate to facilitate bandwidth and power optimization, fast channel switching, and real-time mobile traffic and network analysis, displays and alerts.

A system and method for quarantining IP service devices (ISDs). When an ISD is placed into a quarantined environment, any request from the ISD will be re-directed to a quarantine alert server in a quarantine sub-system. In response to the request, the quarantine alert server may provide the user with information about the quarantine and may redirect, or instruct the user to redirect, the request to a quarantine response server. The quarantine response server may provide additional information that is not in the quarantine video message as to how the user may end the quarantine.
