Carrier Grade Ethernet- Since Ethernetis extremely simple to operate and is inexpensive, it has highly gainedpopularity in transport network operator. Since transport network have hugenumber of attached devices, scalability is very important. For corporatecustomers, to meet the requirements of QoS, SLAs are defined which includesbandwidth, availability, delay and jitters.Ethernet in the first Mile- uses existingcopper pairs to provide fixed connection speed, symmetric bandwidth up to 35 Mb/swithin an Ethernet enabled exchange. With this one can extend network reach by providingcost-effective and flexible alternative to fiber. This helps small andmedium-sized enterprises (SMEs) to move to hosted cloud environment.
Avionics Ethernet- ARINC 429 data bus hasbeen used by civil avionics applications, but the data bus has its limit of100Kb/s which is not sufficient owing to the increased complexity of avionicssystems. In order to reduce the development costs, Avionics full duplex switchedEthernet was introduced(AFDX). Its integration in Airbus 380 was great successin civil avionics and because of this it has become attractive for adoption inmilitary avionics as well.Audio and Video Bridging Ethernet- With risein home multimedia, customers are attracted towards the technology of accessingcontent and resources from anywhere in the house using their own devices.
Ethernet finds its use in such applications as well. The changes of MAC and802.1D bridges would enhance the old Ethernet technology allowing it to providelow latency service for streaming applications.Among many fields of application, AutomotiveEthernet interests me majorly.
We did not see the Ethernet being used inautomobiles even though it existed way before, since it could not bring downthe latency levels to microsecond range, it did not find a way to controlbandwidth and it could not synchronize time between devices. The demand foradvanced infotainment features and better driver’s assistance is on rise now,hence great demand in automotive Ethernet use. The most used in-vehicle networktechnologies are LIN, CAN and MOST, all of which are automotive specific, butthey are reaching its capacity limits. Ethernet is low cost network technologywhich also fulfills the in-vehicle network requirements.
When it comes to infotainment, we need interactiveand streaming applications. Ethernet has flexible frame which means that it hasfull control over the flow of the data, transmitting few bytes at highfrequency and transmits frames of large size. Also, customers have the tendencyto connect their personal devices to the in-vehicle network which createsadditional traffic and so for critical domains need to be isolated from suchtraffics, for this VLANs are used which isolates the broadcast domains thus notaffecting any domains.The number of smart cars have risen afterBMW, Volkswagen and Jaguar have launched their respective smart cars that areequipped with WiFi hotspots, music docks, smartphone chargers etc. Apart fromthis, the Automotive Ethernet cables also reduces the labor cost by nearly 50%.
Because of all these features Ethernet is considered as potential backbone technologywhich can also carry CAN and other bus system traffics. Ethernet has shown itsadaptability in picking up new technology towards wired and wirelesscommunication compatibility choosing to be stay in automotive industry.
