SLA Service

1.
The SLA service can be classified into multiple levels in terms of protection (high level
service, medium level service, reroute service, unprotected service and extra service,
and so on). Charges vary with the service levels and thus demands of different users
can be satisfied flexibly. The principle for classifying services is as follows:

Diamond
Gold
Silver
Copper
Iron
Diamond level service is to meet demands of users such as banks, securities,
important government offices, and so on. Gold level service is to satisfy the demands
for speech, multimedia and video. Silver level service is applicable to common data
service transmission. Services of copper and iron levels are suitable for applications
such as family network access
preconfigured route; support span protection and end-to-end service protection,
improving the scalability of the network.
Classification of SLA Service
High level service: Provided with 1+1 protection or alike, with the switch-ing time of
0–50ms.
Medium level service: Provided with M:N protection or alike (for example, two-fiber
MSP), with the switching time of 0–50ms.
Reroute service: Recalculate the path in real time, with the switching time from
100ms to several seconds.
Unprotected service: Provided with no protection in the case of any fault.
Extra service: Pre-empted by services with higher priorities when the network
resource is insufficient.
