What is PLE?
Circuit emulation is a proven and tested technology, used to transport legacy services across packet networks.
Private Line Emulation (PLE) utilizes established concepts for the transport of high bit-rate client signals across a packet network. It borrows the packetization and packet header encapsulation from SAToP, and mandates the use of Differential Clock Recovery to enable excellent reconstruction of client signals at the far-end to comply with the demanding jitter and wander requirements for SONET/SDH and other client signals.
High bit-rate signals at 25 Gb/s and above often use multiple signal lanes and forward error correction (FEC). These traffic streams need to be locally processed before transport. The PLE standard describes native service processing functions specific for each of the supported client signal types.
New IETF Standard
Currently a new method for transparent high bit-rate transport is being worked at in an internet-draft and submitted to the Internet Engineering Task Force (IETF).
4️⃣ Reasons to use our Smart SFPs to emulate OTN, SONET, or SDH services
1️⃣ Versatility
With our Smart SFPs, any system can become a Private Line Emulation (PLE) supported system. The PLE standard for emulating OTN, SONET, SDH, or Fibre Channel is maturing. However, only a limited number of systems currently support this natively. Smart SFPs can solve this problem conveniently.
2️⃣ Interoperability
Interworking between PLE boxes and PLE Smart SFPs is possible. Are you considering PLE by deploying dedicated boxes on central locations? But also have locations with one or two connections and thinking of deploying Smart SFPs there? As we are closely working with other vendors, interworking is guaranteed.
3️⃣ Visibility
All our Smart SFP platforms are supporting in-field upgrades making it possible to add new features even after deployment. Thinking of an incremental way of adding features to existing Smart pluggables? Need features exclusive for you? No problem!
4️⃣ Flexibility
Native management from the host platform is supported. Need visibility of the emulated service within a Smart SFP? Want to configure the Smart SFP from the host-system’s CLI? We are working with almost all the Tier 1 Network Equipment Manufacturers (NEMs) allowing them to completely integrate our Smart SFP in the CLI of their switch or router.
AimValley has over 10 years of experience with Smart SFP designs and we have over 20 years of experience in FPGA designs and turn-key product development with Tier 1 Network Equipment Manufacturers.
We have a long history of offering several solutions for E1/T1/T3 and SONET/SDH, for instance using SAToP or CEP protocol in our line of Smart SFPs.
