Abstract: A system and method for measuring a propagation delay in a point to multipoint network. The system includes a central timing module which provides a timing signal to a plurality of line cards. Each of the line cards includes a local clock that is frequency locked to a 1588 clock and is configured to generate a return timing signal to the central timing module after a predetermined number of clock cycles. The central timing module measures the propagation delay based on the clock cycles of the local clock counted before the return signal is generated and the period of the local clock.

Abstract: A networking device and a method provide switching of framed signals using a packet switch fabric. Framed input signals, which may be OTN signals, are received and converted to packets. The conversion includes striping the received signal into virtual lanes and segmenting the lanes into packets. The packets are switched through the packet switch fabric, which may be an Ethernet switch, and then converted to framed output signals. The conversion includes reassembly of the packets into virtual lanes. The reassembled virtual lanes are frame aligned, deskewed, and combined to produce the framed output signals.
