An incoming CBR client stream is segmented into variable sized segments, such as packets or general framing protocol (GFP) frames, and is regenerated on the other side of a fabric or network phase-locked to the incoming stream. Regeneration of the CBR client clock is based solely on segment sizes, and in the case of GFP frames, the rate of the SONET Path or OTN ODUk stream carrying the GFP frames. No overhead bytes are inserted into the GFP frames to convey phase and frequency information. The method disclosed is important for reducing the cost and complexity of communications networks by allowing CBR clients to be transported with low jitter and wander without requiring the source and sink network elements to be phase-locked to a common stratum reference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for transporting constant bit rate clients across a packet interface","description":"A method and apparatus are described for signaling the phase and frequency of constant bit rate (CBR) clients over a network or fabric.
