  2. Agile All-Photonic Networks • Reliable • Provisions sub-multiples of a wavelength • Large number of smaller edge nodes Edge node with slotted transmission (Gb/s min. capacity) Fast photonic core switch AAPN Optical / electronic interface AAPN AAPN

  3. Deterministic Packet Marking • Price-based congestion control mechanisms require estimate of sum of link prices • Two bits per packet (only three symbols available) • Probabilistic marking schemes: high variance • Deterministic Marking • Quantize each link price • Use IPidentifier field to focus on individual links
