Abstract
A method for a first network to receive a packet from a second network is provided, including a router at the first network receiving the packet from the second network, the packet addressed to a client reachable through the first network; the router inspecting the packet for a nonrepudiable marking provided by the second network; if the nonrepudiable marking is present and matches the packet, adding an indicator pointing to the second network in the packet; adding a second nonrepudiable marking to the packet, and transmitting the packet to a destination; and otherwise, dropping the packet.
Claims15
A method for a first network to receive a packet from a second network, comprising:
- a) a router at said first network receiving said packet from said second network;
- said packet addressed to a client reachable through said first network;
- b) said router inspecting said packet for a nonrepudiable marking provided by said second network;
- c) if said nonrepudiable marking is present and matches said packet, adding an indicator pointing to said second network in said packet;
- adding a second nonrepudiable marking to said packet, and transmitting said packet to a destination;
- and
- d) otherwise, if said packet is received over a low spam overlay, dropping said packet.
A system for reducing spam messages within a plurality of networks, comprising:
- a first network within said plurality of networks, said first network having entered into a peer-to-peer quality of service agreement with at least a second network within said plurality of networks;
- said agreement providing a predetermined limit of an amount of spam messages sent from said second network;
- said first network passing messages received from said second network with a verified digital signature of said second network to clients of said first network;
- wherein if said messages from said second network sent to clients of said first network exceed said predetermine limit on the users of said amount of spam, said second network compensates said first network.
A first network for receiving and transmitting packets to a plurality of other networks, wherein a first selection of networks with said plurality of networks has entered into a peer-to-peer quality of service agreement with said first network to control the transmission of spam, and a second selection of networks within said plurality of networks have not entered into a peer-to-peer quality of service agreement with said first network to control spam;
- comprising:
- a computer within said first network, said computer configured to receive and transmit packets received from said plurality of networks, and to transmit packets generated within said network, and to transmit packets to a client of said first network, when said packet is addressed to said client;
- wherein when said computer receives a packet from a network within said first selection of networks, and said network within said first selection of networks has digitally signed said packet, said computer digitally signs said packet and transmits said packet to a destination;
- and
- wherein when said computer receives a packet from a network within said second selection of networks, said computer treats said packet as potential spam, and if said computer transmits said message, said computer does not digitally sign said packet.
