SDL Protocol for Next Generation Packet Network
Xiang Cui, Pla Uni · Journal of PLA University of Science and Technology · 2002
The SDL is a new protocol mainly applied to a general point to point channel for variable or fixed length packets framing. It extends the HEC framing mechanism of ATM to variable length packets. It is particularly suitable for high speed transport links in WDM channels because of its low implementation complexity. SDL also facilitates many OAMP functions needed in next generation multiservice optical packet networks. Under the high data rate environments, SDL is a very attractive alternative to conventional solutions such as ATM and POS. This article describes framing and data link synchronization procedures in SDL, and presents its performance evaluation.
