Electrical-bitstream transport Clause Samples

Electrical-bitstream transport. ‌ For electrical-bitstream transport, the ARN is a key device, which needs to support Open Access functionalities. The ARN connects residential users, businesses and RBS to the network and each of them may belong to different ISPs. Therefore, customer identification, segmentation and QoS are key within SODALES. As SODALES implements statistical multiplexing features at the ARN, also, non-discriminatory policies need to be defined to guarantee fair access to the upstream channels. ARN 120G 40G 10G 10G 10G 10G l1 2×10G l 40G 48×1G 2 40G 48×1G 1×RBS@10G 3×SME@10G 96×Res@1G The SODALES architecture needs to support the required functionalities to offer Open Access features, which are:  Scheduling hierarchies: port, service provides (logical port), user, priority  E-Line  E-LAN  E-Tree  APS Together, these will provide the required traffic isolation, end-to-end customer management and Quality of Service. The service provider and the end-user coordinate between them the required service in terms of standardized service types and service attributes. These Carrier Ethernet service types are fundamental to the Carrier Ethernet service model and are defined in MEF 6.1.
