What does "carrier-class packet
transport" mean? I am thinking maybe its how the heavy hitters (XO,
SBC, Level 3) move packets on the internet, but I am guessing.
Thanks

Hi Jimmy,
From transformation to IP-based packet transport network (PTN) has garnered industry-wide attention as the most expedient remedy. PTN is generally regarded as a connection-oriented transport network technology. Based on IP technology, it is applicable to a multi-service environment and capable of accessing, converging and transporting "TDM/ATM over Packet" and "packet-only" services.
Nevertheless, IP technology possesses certain innate drawbacks that negatively influence its position as a carrier-class service transport mechanism
The features that PTN technology requires to render it carrier-class are detailed below.
1) Highly precise network synchronization
2) End-to-End QoS guarantees
3) SDH-like OAM and network protection
4) Uniform multi-service transport and management platform
