    Dear All,

    Could anyone please tell me the basic and pratical difference between
    MSP and SNCP?
    Also can someone tell me when can we use MSP and when can we go for
    SNCP?


    I know the practical set-up for both but couldn't figure out when to use which one of these two. With advantages and disadvantages of
    each.


    Hope the reader would be clear with my query and will be able to
    provide me the details.


    Thanks for your inputs in advance.

    Can anyone tell that we can implement MSP and SNCP in PTP , Ring or mesh typologies ...???
    Is MSP applied between two nodes only and SNCP in entire ring to protect the services end to end ...???

    Did you read my response to Ankurs questions?
    I explained the difference at that time (July 3 2007)

    Also read ITU-T recommendation G.841 which describes these types
    of protection.
    In short:
    -- MSP is section protection between two adjacent nodes
    -- SNCP is path protection between two end-points (AKA linear protecton)
    -- MS-SPRing is ring protection

    Hi Mr.Huub ,

    about the switching timing in SNCP,MSSP,MSP what are the factors to determine the time?
    and SNCP is dual fed and selective receiving why the passing through nodes effecting the time switching?

    and another Q for MSSP , why is the limitation only for 16 nodes? is this only becuase k1,k2 4 bits, is there other reason ?

    The switch time is measured from the time a defect (like signal fail)
    has been detected until the service has been switched and is restored.

    This includes transmission latency (5 ms per 1000 km), the node latency
    20 microseconds per node, and the processing time (implementation
    dependent.

    and SNCP is dual fed and selective receiving why the passing through
    nodes effecting the time switching?

    The APS protocol processing time at both endpoints determines the
    switching time.

    and another Q for MSSP , why is the limitation only for 16 nodes?
    is this only becuase k1,k2 4 bits, is there other reason ?

    It is indeed because there are only 4 bits available.
    It is not very likely that there are more than 16 nodes in a ring.

    Best regards, Huub.

    Why only 16 node can be in msp??

    If you look at the APS bytes/bits you will notice that there are
    only four bits allocated for the node ID. This limits the number
    of node to sixteen.

    More than 16 nodes on a ring will affect the response/switching
    time which should be less than 50 ms.

    Best regards, Huub.

    Your question is too brief for me.

    What is the information that you would like to see?

    Best regards, Huub.
