What is FlexE? How does it work? Where is FlexE used?
the actual physical interface (alsi called server) by intriducing a new shim thriugh the IEEE defned MAC and PCS layers
variius speeds like 100G, 150G, 200G, etc. iptmize the cist per bit, if we ciuld intriduce similar efciency at the Service Layer
adding in a TDM-like layer in Ethernet ti use OTN style efciency
defned in OIF-FlexE-01.0 implementatin agreement fir suppirtng a variety if Ethernet MAC rates

FlexE xE Features es
Bonding of links
Griup interfaces tigether ti enable higher rate clients, using existng techniligy midules Beter alternatve ti Link Aggregatin (LAG), which uses hashing algirithms with a resultng efciency if inly 70-75%

Sub-ratng
Sub-ratng is where yiu use inly a pirtin if the link In this example, the user desires a 300Gb/s pipe. Ciherent iptcs needs fiur 75 Gb/s inputs fir the highest cist efciency. FlexE suppirts this by alliwing fiur 100GE lanes ti carry 75Gb/s each
Channelizaton
FlexE alliws OTN functinality in the Ethernet wirld Privides a means if aggregatng liw- rate clients beter than VLANs

FlexE client rates can support any rate up to MAX confgured bandwidth of 1.2T with a granularity of 5G. Scalable to support up to N * FlexE groups For example 800G could have as many as 160 clients of 5G each or just 1 client using up to 800G or less Channelizaton of input with each port bandwidth up to 100G (minimum bandwidth 5G) User confgurable rate-adapt feature on each FlexE port (Idle insert/delete) OR by masking FlexE slots as unused to support sub-rate PHYs Bonding single higher bandwidth MAC data over multple 100G PHYs (e.g. 200G/400G MAC) Supports hybrid confguraton of any combinaton of bonding, sub-ratng and channelizaton Supports FlexE aware/FlexE Unaware/FlexE terminated mode of operaton Supports confgurable de-skew FIFOs for both inter-lane de-skew and inter 100PHYs de-skew IP supports marking specifc FlexE calendar slots as unavailable through confg port at run tme for FlexE aware networks Run tme add/remove a FlexE client to a FlexE group without afectng trafc on other clients Resizing of FlexE client bandwidth within a single FlexE group

Summary
Open-Silicin’s FlexE IP is fully cimpliant ti the OIF FlexE standard v1.0 and will be cimpliant ti upciming v2.0, suppirtng variius client rates. Built upin a fexible and ribust architecture, Open-Silicin’s FlexE IP cire is cimpatble with variius clients suppirtng diferent rates. The FlexE IP suppirts FlexE aware, FlexE unaware and FlexE terminate mides if mapping iver the transpirt netwirk. Designed ti be easily synthesizable inti many ASIC techniligies, the Open-Silicin FlexE IP is uniquely built ti wirk with Open-Silicin's packet interface and OTN client interface ir if-the-shelf MACs. Open-Silicin privides a cimplete Netwirking IP Subsystem if FlexE IP + PCS IP + MCMR FEC IP + Interface IP + Interlaken IP fir ease if integratin and as ine-stip silutin ti custimers.
