Upstream Networking Protection
Protection Scheme
Description
Suggestion
Link aggregation
group
Multiple Ethernet ports are bound
together as an aggregation group to
increase the bandwidth and balance
the inbound and outbound load of
each member port. In addition, the
ports in an aggregation group back up
each other, which enhances the
reliability of links.
This protection scheme is
mandatory when the GIU
board is used to transmit
traffic upstream.
Protection group
(Ethernet/STM-1)
A protection group of upstream ports
contains a working port and a
protection port. In normal state, the
working port carries services and the
protection port does not. When the
link at the working port is faulty, the
system automatically switches
services from the working port to the
protection port to ensure normal
service transmission and protect the
uplink.
When the main control
board is used to transmit
traffic upstream, this
protection scheme is
mandatory.
This protection scheme is
recommended when traffic
is transmitted upstream
through STM-1 ports.
NOTE
Link aggregation group and Ethernet protection group usually are not configured at the same time. You are
advised to configure only one of the two protection schemes.
Downstream Networking Protection
Protection Scheme
Description
Suggestion
xPON Type B
Two PON ports on the same OLT
back up each other. When one of the
PON ports fails, the system
automatically switches to the other
PON port. This protection scheme
provides port-level protection with
low costs. It protects services against
fiber failure at the working port.
It rovides port-level
protection and has a low
cost. The inter-board
protection mode is
recommended.
GPON Type C single
homing
Two PON ports on the same OLT,
two PON ports on an ONU, two
backbone optical fibers, two optical
splitters, and two tributary optical
fibers are configured to provide link-
level protection.
It rovides link-level
protection.
