Eurofiber’s fiber-optic network with nationwide coverage is fast and reliable, making it ideally suited for additional Ethernet services. Since 2008, Eurofiber has been delivering additional Ethernet services based on virtual private network (VPN) technology.
For example, a VPN connection can be used to link multiple sites without compromising security. Thanks to VPN technology, the linked sites are seen as an integral part of the company network (the local area network or LAN). Services such as internet access, telephony and video streams can be ported via the VPN. Eurofiber offers a number of Ethernet VPN variants on its network:
- E-Line, a point-to-point connection between two ports at customer sites. Optionally, it could be completely transparent for all of the organization’s data traffic.
- E-Access. These are point-to-point connections between a location and a network-to-network interface (NNI). The connections on the NNI are delivered as different virtual LANs; a specific location is connected through each VLAN.
- E-LAN. Multiple locations are connected as if there were an Ethernet switch in the network that correctly delivers all data packets to a location based on the MAC address in the Ethernet frame.
Eurofiber has an open network, so it’s important to offer standardized services. To guarantee this standardization, Eurofiber’s services have been certified by the Metro Ethernet Forum (MEF), the international organization that defines standards for Ethernet and related fields. Eurofiber’s E-Line and E-LAN service are MEF9 and MEF14 certified, and our E-Access service has been MEF CE 2.0 certified since early 2018.
Quality of Service
For some information flows running over Ethernet VPNs, the loss of data packets is undesirable; examples include video conferencing and telephone services. Prevention of data loss is ensured by defining quality of service (QoS). QoS can be used to set the priority level for flows of data traffic. In the event of ‘network congestion’ on a particular link, the lower-priority packets will be discarded, while the packets of the premium service will be prioritized.
Eurofiber currently delivers some 15,000 Ethernet services over its network, divided between E-Line and E-LAN. Services are delivered on over 7,500 CPEs of various types, on ports of our routers, and on dozens of NNIs of various partners, major carriers and wholesale customers. Underlying the MPLS network, most services are set up as Virtual Private LAN Services. Based on that technology, a virtual switch is created on our MPLS routers for each service. The virtual switch contains the customer’s traffic and addresses, isolating it from other customers’ traffic. You can rest assured that your valuable data remains within your organization.
