An all-optical fast wavelength switching at 10 Gbit/s between 200 GHz-spaced channels using a digitally tunable external cavity laser and semiconductor optical amplifier-based wavelength converter

ATM networks are used to carry a variety of types of traffic.

Per-flow network traffic measurements are needed for effective network traffic management, network performance assessment, and detection of anomalous network events such as incipient DoS attacks.

We consider the problem of fast estimation of flow rates in backbone network links with possible millions of flows.

: We demonstrate a digital coherent 224-Gb/s (56-Gbaud PDM-QPSK) packet receiver that selects packets using a fast wavelength-switching local oscillator.

We demonstrate a fast wavelength-tunable burst-mode receiver for coherent 28 GBaud DP-QPSK signals using a commercially available DS-DBR laser as the local oscillator.

The FASTARSM Operations System Platform is a set of systems that provide AT&T's fast automated restoration capabilities.

The "packaging" of an electronic system is thr translation of the system designer's concepts into physical realities.

Sliding window measurement is required by network functionalities such as load balancing, traffic engineering and intrusion detection.

MPTCP's ability to bond interfaces regardless of the underlying technologies offers capacity boost and resiliency for applications in multi-access wireless networks.
