Abstract:

Ethernet linear protection is a significant characteristic of the PTN network to meet the needs of the operator level. In order to guarantee the transmission of
service in the PTN network equipment with reliable transmission channel and selfhealing ability to recover the faulty link, this paper discussed a linear 1∶1 protection
switching mechanism based on G.8031 protocol, realized the fast automatic protection switching function of the main and standby link within 50 ms of the telecommunication level,
and improved the reliability of PTN network.

Key words:  , PTN network; G.8031 protocol; linear 1∶1 protection; reliability
