pathChirp is an active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "self-induced congestion," pathChirp features an exponential flight pattern of probes we call a chirp. Packet chirps offer several significant advantages over current probing schemes based on packet pairs or packet trains. By rapidly increasing the probing rate within each chirp, pathChirp obtains a rich set of information from which to dynamically estimate the available bandwidth.

RC5 encryption algorithm is a new fast symmetric block cipher developed by Ron Rivest for RSA Laboratories. Intended as a possible successor to the Data Encryption Standard, RC5 has a variable word size, a variable number of rounds, and a variable-length secret key, so the user can explicitly manipulate the trade-off between higher speed and higher security. RC5 is suitable for hardware or software implementations; the encryption and decryption algorithms are exceptionally simple. A novel feature of RC5 is the heavy use of data-dependent rotations.
