Connectivity Fault
Management (CFM)
A standard defined by IEEE, used to diagnose fault for Ethernet
Virtual Connection (EVC). Cost-effective by fault management
function and improve Ethernet maintenance.
E
Ethernet Linear
Protection Switching
(ELPS)
It is an APS protocol based on ITU-T G.8031 standard. It, an
end-to-end protection technology, protects an Ethernet link. It has
two linear protection methods: linear 1:1 APS and linear 1+1
APS.
L
Link Aggregation
With link aggregation, multiple physical Ethernet ports are
combined to form a logical aggregation group. Multiple physical
links in one aggregation group are taken as a logical link. Link
aggregation helps share traffic among members in an aggregation
group. In addition to effectively improve the reliability on links
between devices, link aggregation can help gain higher
bandwidth without upgrading hardware.
