Abstract: A remote attestation system for a computer network includes an attestation operations subsystem configured to manage attestation procedures for the remote attestation system, and an attestation server pool including a plurality of attestation servers. The plurality of attestation servers is configured to perform attestation of at least one host in a data center. The system further includes an attestation state database configured to store a state of attestation of the at least one host, an attestation policy database configured to store at least one operator policy of the computer network, and an end-user service portal configured to provide access to the remote attestation system by users of the computer network.

Abstract: An optical network communication system includes an optical hub 442 at the head-end, an optical distribution centre 404, connected by at least one fibre segment 408, and at least two end users 406 downstream of the distribution centre. The optical hub includes an intelligent configuration unit (not shown) which multiplexes at least two different optical signals 441(1), 441(2), 441(3) into a single multiplexed heterogeneous signal. The optical distribution centre demultiplexes the heterogeneous signal. The heterogeneous optical signal comprises an optical signal of a first type and an optical signal of a second different type, each selected from the following: an analogue optical signal 418, an intensity modulated signal suitable for direct detection (e.g. PAM, RZ or NRZ), a signal suitable for coherent detection (e.g. BPSK, QPSK or higher order QAM), or a differentially modulated signal (e.g. DPSK or D-QPSK). Also claimed is a method of assigning wavelength spectrum based on characteristics of the fibre segment and parameters of the at least two different optical signals. The distribution centre may include a wavelength filter 446 and a downstream optical switch 448.

Abstract: An optical network communication system includes an optical hub, an optical distribution center, at least one fiber segment, and at least two end users. The optical hub includes an intelligent configuration unit configured to monitor and multiplex at least two different optical signals into a single multiplexed heterogeneous signal. The optical distribution center is configured to individually separate the at least two different optical signals from the multiplexed heterogeneous signal. The at least one fiber segment connects the optical hub and the optical distribution center, and is configured to receive the multiplexed heterogeneous signal from the optical hub and distribute the multiplexed heterogeneous signal to the optical distribution center. The at least two end users each include a downstream receiver configured to receive one of the respective separated optical signals from the optical distribution center.

Abstract: A communication system includes an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite. The communication system further includes a server in operable communication with the earth station, a beacon detector in operable communication with the server, an access point configured to operate within a proximity of the earth station, and a beacon transmitter disposed within close proximity to the access point. The beacon transmitter is configured to transmit a beacon signal to one or more of the server and the beacon detector. The beacon signal uniquely identifies the access point. The server is configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission.

Abstract: An injection locked transmitter for an optical communication network includes a master seed laser source input substantially confined to a single longitudinal mode, an input data stream, and a laser injected modulator including at least one slave laser having a resonator frequency that is injection locked to a frequency of the single longitudinal mode of the master seed laser source. The laser injected modulator is configured to receive the master seed laser source input and the input data stream, and output a laser modulated data stream.
