Requirements for SPN Information Modeling

SPN Network Architecture SPN (Slicing Packet Network) is a new transport technology , which includes new protocols， new optical and new control.

ITU-T G. mtn standard Scope two new non recursive layer networks (path and section) that will be used in the metro networks, including the G. mtn will define transport of D RAN and C RAN Ø The path layer provides flexible connections that carry client data and path OAM in 64 B/66 B blocks that are conformant to IEEE 802. 3 clause 82 encoding rules and results in valid 802. 3 64 B/66 B blocks, which allows using the lower layers of the Ethernet protocol stack. OAM functions include connection verifications, PM, path status and delay measurement. Protection overhead to support path layer SNCP will also be supported. Ø The section layer frame format will be defined in a way that maximizes reuse of Flex.
