In this question, in the context of point -to -point fiber links, the choice between 1s to 1 and 1s to n protection schemes depends on the specific requirements and priorities of the network.
00:18
So, let's examine each scheme and their respective advantages and considerations.
00:26
So, first let's take 1s to 1 protection.
00:35
Now in this, in a 1s to 1 protection scheme, a dedicated backup fiber is provisioned for every primary fiber.
00:53
So these two links are physically diverse and typically flow different paths to ensure redundancy.
01:03
Okay, so what are the advantages of this 1s to 1s? first is it enhanced reliability.
01:20
Second is isolation of failures.
01:38
Since each primary link has its dedicated backup, failures on one link do not affect others.
01:45
It offers high fault tolerance.
01:49
Okay, so let's talk about the second scheme.
01:56
This is 1s to n protection scheme.
02:06
Now in this 1s to n protection scheme multiple, primary fibers are protected by a shared set of backup fibers.
02:24
The backup fibers are typically configured to handle the traffic of multiple fibers simultaneously.
02:38
So in this, there are multiple primary fibers which are protected by a shared set of backup fibers.
02:52
So it is not like in 1s to 1, every fiber has its own single backup fiber.
03:00
So, what are the advantages of this 1s to 1 protection scheme is it is cost effective and second, it is efficient in fiber utilization...
