4) Quality of Service - This attribute can specify end-to-end bandwidth and performance requirements. It uses SLAs that deliver end-to-end performance meeting voice, video and data requirements across converged business and home networks. This gives a wide choice and freedom of bandwidth and QoS options. 5) Service Management - This gives the ability to centrally monitor, diagnose and manage the network, using standard implementations independent of the supplier. We can achieve fast service delivery with this attribute. It can also be considered an OAM carrier class.VIII. TYPES OF CARRIER ETHERNET SERVICESCarrier Ethernet includes the following service types: 1) General Service Type: This service type offers connectivity services or access-based services and applications enabled via Ethernet. Figure 4 shows the range of Ethernet services provided by AboveNet communications. We can see that they provide access-based services for Internet access, VOIP, storage expansion, etc. Fig.4 - AboveNet Ethernet Service Portfolio (Source: Heavy Reading) 2) Specific Service Type - Figure 5 shows an exact representation of specific service types. Fig-5 Port-based MEF Ethernet service types and VLAN-based service definition (source: MEF Ethernet Carrier White Paper on Providing Private Cloud Services at MEF.org[12]) MEF has classified the Ethernet-based services based on the type of connectivity they provide. .• E-Line for point-to-point connectivity• E-LAN ​​for multipoint-to-multipoint connectivity• E-Tree for rooted multipoint connectivityThe EVC is the logical representation of an Ethernet service instance. The EVC may also support one or more classes of service and measurable QoS performance metrics, such as frame...... middle of paper ...... the above diagrams will LR4, SR4 and SR10. 40GBASE-LR AND 100GBASE-LR4 single-mode fiber cable options, two fibers are required to establish a full-duplex transmit and receive link. In each fiber, four lasers will be combined to transmit signals in one direction using wavelength division multiplexing (WDM). In the case of 40 Gb/s, each “lane” will transmit 10 Gb/s and 25 Gb/s for 100 Gb/s. The following diagram illustrates this method: Fig.5 Looking at the multi-mode options of 40GBASE-SR4 and 100GBASE-SR10, we will need multiple fibers to transmit and receive signals, each capable of 10 Gb/s transmission. For 40GBASE-SR4, there will be four fibers in each direction for a total of 8 fibers, each transmitting at 10 Gb/s. For 100GBASE-SR10, there will be 10 fibers in each direction for a total of 20 fibers, each transmitting at 10 Gb/s..
