Abstract: A method and system for tracing internet protocol packets is disclosed. One aspect of the method involves generating traceback packets containing information relating to their origin, destination, and encountered devices. The generated traceback packets can differ depending on the network configuration and Internet traffic scenarios. Another aspect involves analyzing incoming Internet traffic and generating traceback packets based on the performed analysis. Another aspect involves discovering a denial-of-service attack. Another aspect involves modifying operational parameters in response to the attack. One aspect of the system involves traceback servers, which can collect and provide traceback information to the public or on a private network. Another aspect involves the dissemination of traceback information to interested and/or authorized parties.

Abstract: A drug release products and methods are disclosed. The drug release product has one or more compartments containing drugs and a space with control elements. The control elements control the timing and the dosage of the drug release by opening compartments at particular times. The control elements use information from on-board sensors, from a probe located in another part of the patient's body or from external device to determine the timing of opening the compartments. The product with the unopened compartments and control elements leaves the patient's body through the normal digestive process.

Abstract: The deterministic packet marking (DPM) method is based on marking packets with the partial address information of ingress interface only. The attack victim is able to recover the complete address(es) information after receiving several packets from a particular attacking host or hosts. The full path is not really essential for the traceback since it can be different for different packets for different reasons. In order to deal with fragmentation, it is required that the ID field (as well as some other fields) of all the fragments in a given series is the same. DPM randomly selects the marks from the pool, which is created at startup. The mark completely occupies the ID field in the IP packet header, as well as Reserved Flag. Since every single packet passing through the DPM-enabled interface is marked, the ID field of all the fragments of a series are ensured to be the same.

The attack victim is able to recover the complete address(es) information after receiving several packets from a particular attacking host or hosts. The full path is not really essential for the traceback since it can be different for different packets for different reasons. In order to make tracing slaves from reflectors possible, the potential reflectors keep the log of two fields of every packet, which they receive. The two fields are source address for the mark. The entry is kept in the log for a reasonable period of time in order for the victim to be able to use that information. By analyzing the marks from the logs, which cannot be spoofed, and that are sure to be from the slaves, the victim can reconstruct the ingress addresses of the slaves which sent the packets to the reflectors.
