A system and method for providing a quarantine network to address threats emanating from viruses and worms. A quarantine network quarantines an infected terminal's traffic from the normal traffic flow. During the quarantine period, all of the traffic is analyzed by a quarantine network component. Based upon the results of this analysis, the network can restrict the access of infected terminals to various services, as well as prevent other devices from becoming infected by blocking infected materials such as attachments from reaching their respective recipients.

System and method for using quarantine networks to protect cellular networks from viruses and worms

A method and system of handling traffic flows across a network is disclosed. The method includes issuing a request for establishing a first communication pathway end to end over the network, the communications pathway including the radio communication channel and the packet communication channel, the request identifying multiple traffic flows with their associated attributes. The method further includes identifying any of the traffic flows which require a different flow treatment across the network, and establishing the first communication pathway, and at least one second communication pathway end to end over the network, the second communication pathway providing a different flow treatment.
