What is PTN?

PTN typically refers to Packet Transport Network. It is a connection-oriented technology used in telecommunications networks for efficient and reliable transport of various types of traffic, including Ethernet, TDM, and ATM. PTNs often employ technologies like MPLS-TP or PBB-TE to provide traffic engineering, QoS, and OAM capabilities, enabling operators to deliver high-bandwidth services with guaranteed performance. It's used for mobile backhaul and business services, among other things.
