IP+Optical OAM Challenges of E2E 100GE
Cannot detect the failure in time
RA RB OTN1 OTN2
100GE
No.1: Failure detecting
The 100GE cannot provide accurate detection mechanism, like
SD/SF of SDH/OTN.
PHY error counters in PCS layer just detects the invalid
synchronization header, can not evaluate the real BER.
NO.2: OAM signal pass between routers over OTN
LF/RF(Local Fault/Remote Fault) defined in 802.3ba need to be
passed through OTN

OAM solution1：Router Integrated with OTN Interface
OPU

OTU4_BDI RA OTN/WDM1 OTN/WDM2 RB
OTN interface
RA RB OTN1 OTN2
OTN Interface integrated in router can make full use of rich OAM features of OTN to
implement E2E 100GE OAM.(This will be planned in the near future)

OAM solution 2：BIP8 & LF/RF
IEEE802.3ba 100GE
RB Processing:
1. detect HI-BER or BIP8-EXC
2. Set local link down
3. Reflect Remote Fault to RA
4. Trigger FRR
5. report Local Fault
RA Processing:
6. Receive Remote Fault
7. Set local link down
8. Start FRR
9. Report Remote Fault
Implement performance detection in 100GE interface with BIP8
Implement OAM signal translation between OTN & Ethernet with G.709v3

RA RB OTN1 OTN2
Wherever there is failure at 100GE client interfaces or inside transport network, OTN will turn off the
bidirectional client lasers to notify the router for implemention of fast switchover.(For 100G, LPT is to be planned)
