One of the central design consider- of the test plan. ations for the network was to enable any device Please note that we use the term »tested« when positioned in the access network to reach any other reporting on multi-vendor interoperability tests. The access network device regardless of the other term »demonstrated« refers to scenarios where a device’s point of attachment to the network. This service or protocol was terminated by equipment proved to be especially useful for such end-to-end from a single vendor on both ends. tests as Service OAM or Mobile Backhaul. The specifics of these tests can be found in the test case sections. ETHERNET SERVICE TYPES We also aimed to build a network that would look The Metro Ethernet Forum (MEF) has defined three familiar to service providers. It is perhaps unrealistic Ethernet service types in order to allow the industry to expect that service providers will incorporate all and specifically the customers interested in the current transport technologies into their network. services to have a common language to discuss such Nevertheless the familiar network domains are likely Ethernet based services. The three service types are to exist: access, aggregation, metro and core, defined in terms of the Ethernet Virtual Connection regardless of the chosen transport technology. It is (EVC) construct: realistic, however, to expect service providers to use MPLS in the core. • E-Line – Point-to-point EVC Looking at the network from a customer’s • E-LAN – Multipoint-to-multipoint EVC perspective, we used the following network areas: • E-Tree – Rooted-multipoint EVC • Access: The devices that normally exist at the While the E-Line service type provides a service to customer premise or by NodeBs or base stations exactly two customer sites, the E-LAN and E-Tree were positioned here. We were lucky to see a service types allow the connection of more than two diverse number of access technologies for trans- customer sites. In contrast to the E-LAN service type porting Ethernet such as microwave links, which allows an any-to-any connectivity between copper, and fiber. These devices implemented customer sites, E-Tree introduces two different roles 4 the UNI-C construct as defined by the MEF. for customer sites: leaf and root.

    Industrial Panel – Wednesday 21 April, 11:15-12:45 Open Solutions for the Next Generation Telecom Infrastructure The telecom infrastructure is evolving towards a progressive but fast integration with the IT infrastructure. In the near future, such integration will allow to deliver new profitable Services and Applications with specific and very high Quality of Transmission and Quality of Service. A suitable composition of open reference frameworks drives the implementation of the Management System of such complex infrastructure. These frameworks are provided by large alliances that include standardisation bodies (e.g., IETF, ITU-T, ETSI), cross-company initiatives (Google, AT&T, Facebook, and many other OTTs, operators and vendors), industrial fora (ONF, MEF, TM Forum) and scientific community. Furthermore, the introduction of the disaggregation concept in the network components is driving commercial solutions towards a standardised architectural approach. In such context, market competition will be mainly delegated to the base technology and the vendors’ capacity to provide enhanced tools for the infrastructure management and optimisation. Integration of those solutions in a comprehensive orchestration framework is a challenge, due to the lack of a single standardised interface. In general, the presence of many competing open solutions raises the question of which one will finally drive the market. In addition, integrated and optimised proprietary solutions appear still preferable when very high performance levels must be achieved (in particular, in terms of reliability and availability). This workshop collects contributions form open-solution providers aimed at presenting the state of the art on this subject. Furthermore, participation of telecom manufacturers and network operators gives the opportunity of sharing visions and specific experiences.
