[RPRWG] TDM or ATM/FR service emulation over RPR ring
Hi All,
Apologize if this question been asked before (pls give a pointer to former
answer then.)
How is the TDM, ATM/FR service emulation provided through RPR ring ?
Is this emulation based on a protocol translation scenario (protocol field
mapping), or raw encapsulation scenario (put TDM/ATM/FR frame as RPR
payload)?
Because I saw some product brochure from vendors, like Luminous, Riverstone,
their MAN box has both Ethernet interface and PDH interface, like E1/T1, and
all through RPR backhaul (said so). It just puzzled me how to emulate these
service through RPR ring.
I've checked RPR whitepaper, and rfc2892, there is no description on
service emulation issue, only a natural L3 IP into RPR frame illustration.
If TDM via RPR ring, anyone considered the stringent timing requirement
from TDM ?
thanks for any input.
Yu Ning
