Conclusion


IEEE 802.3 Ethernet emerging technologies

• Demand for increased bandwidth– By connected devices– By devices aggregating these devices

• Continuing evolution of Ethernet– DTE Power via MDI– Energy-efficient Ethernet– Mapping to OTN

• Convergence around Ethernet– Data Centre Bridging (e.g. FCoE), Audio/Video

Bridging


Increased bandwidth IEEE P802.3ba 40Gb/s and 100Gb/s Ethernet

• Computing– Driven by key technologies

• Internal bus and memory performance– System throughput doubles approximately every 2 yrs

• Core networking– More users, bandwidth, applications– Wide area, ISPs, IXs

• Increase number of users• Increase in bandwidth available; xDSL, xPON, Cable, 3G• Increase number of applications; YouTube, Facebook, Netflix

– Enterprise• Aggregation of multiple computing systems

– Core throughput doubles approximately every 18 months

Connectivity convergence

• Convergence on Ethernet for wired connectivity– Eliminates protocol conversion– Higher volume, lower cost

• Home to Core convergence– Audio/Video Bridging Task Group

• Real time clock distribution, bandwidth reservation

– Data Centre Bridging Task Group• Lossless Ethernet operation, bandwidth assignment

• Increases bandwidth requirements

Conclusion


Conclusions• Ethernet is the ubiquitous wired connectivity

– < 0.01m to 1,000s of kilometres– 10Mb/s to 10Gb/s

• Link Aggregation– Backplane to fibre (and everything in between)

• New speeds, media, features and applications reinforce this– 40Gb/s and 100Gb/s– Energy-efficient Ethernet

• Continued convergence on Ethernet– Data Centre Bridging– Audio/Video Bridging
