Abstract: A method for creating, modifying, and terminating connections between Internet end systems, particularly, although not exclusively, for Internet telephony communication. The method relies on several request messages sent between a client and a server and the response messages sent back in response. Each request and response message may contain one or more header fields which modify or more uniquely link the messages with a given connection. On this basis, advanced telephony services, such as call forwarding, call transferring, and multiparty conferencing are provided.

Abstract: A device receives an attack on a Session Initiation Protocol (SIP) based device, and applies, based on a type of the attack, a method vulnerability based filter to the attack.

Abstract: Systems, methods, media, and devices for providing cooperation among digital processing devices in wireless networks are provided. In some embodiments, methods for moving a connection from one point of access to another point of access are provided, sending a request for information from a first mobile node to at least one other node, wherein the request for information contains first information identifying at least one point of access; receiving a response containing second information identifying at least one point of access from the at least one other node; and establishing a connection between the first mobile node and a point of access identified in the second information. In some embodiments, devices that can move a connection from one point of access to another point of access are provided.

Abstract: A device may verify whether pinholes in a perimeter protection device are open and may determine pinhole opening and closing delays. The method for determining the pinhole opening delay may include sending a stream of packets for passing through the pinhole in the network perimeter protection device. The packets in the stream may be sent at known time intervals. The method may include receiving one or more of the packets in the stream, wherein the received packets passed through the pinhole. The pinhole opening delay may be based on an indication of the position of the first one of the packets received in the stream and the known time intervals. The pinhole closing delay may be based on the number of packets having passed through the pinhole, after sending a session termination message, and the known time intervals.

Abstract: A method may include receiving a session initiation protocol (SIP) request message and determining whether a dialog exists corresponding to the request message. The method may also include determining whether the dialog is in a first phase or a second phase when a dialog exists corresponding to the session control protocol message and querying a table indicating valid protocol requests for the determined phase to determine whether the received request message is valid. The method may include rejecting the request message when determined that the request message is not valid.

Abstract: A method may include receiving a session control protocol request message and fingerprinting the received session control protocol message. The method may further include comparing the fingerprint of the received request message to a list of fingerprints associated with known malicious user agents and rejecting the request message when the fingerprint of the received message matches any fingerprint in the list of fingerprints associated with known malicious user agents. The method may include comparing the fingerprint of the received request message to the list of fingerprints associated with known non-malicious user agents and accepting the request message when the fingerprint of the received message matches any fingerprint in the list of fingerprints associated with known non-malicious user agents.
