Abstract
OTN switching delivers a cost-effective, scalable, low-latency switching layer to address the massive bandwidth scaling required to deal with packet traffic growth. Furthermore, it delivers this scale in such a way that it can transparently transport legacy services such as TDM concurrent with the packet traffic. Service providers are demanding converged packet/OTN boxes, often referred to as Packet Optical Transport Platforms (P-OTPs), which support high-capacity OTN switching as well as packet functions such as Ethernet statistical multiplexing and MPLS-TP switching. TDM traffic is traditionally switched over a TDM-optimized switch fabric, and packet is traditionally switched over a packet/cell fabric. Maintaining two fabrics is challenging in terms of cost, power, and operational complexity. This white paper discusses how OTN switching can be accomplished over a converged fabric which also natively supports packet switching.
