What is an E-LAN?
An E-LAN is a Layer 2 multipoint-to-multipoint connectivity service. In an E-LAN, multiple locations are connected to each other. The exchange of data remains limited up to the endpoints within the E-LAN, creating a virtual private network. Due to the Layer 2 functionality within an E-LAN, every location can exchange data with every other location, just as they would if they were using the same LAN.
This concept is different from an OPN (Optical Private Network), in which an institution has to manage the switching itself. With an E-LAN, the Layer 2 multipoint-to-multipoint switching functionality is provided and managed by the SURFnet network.
Besides being easier to manage, an E-LAN also offers greater flexibility than an OPN. An E-LAN allows endpoints to be added or removed to or from the network without any interruption to the connectivity to other existing endpoints. An E-LAN also allows the bandwidth of the endpoints to be adjusted.
An E-LAN allows for the creation of a 'local' network with national coverage, whereby institutions can connect multiple locations with each other and cooperate with other institutions. A project is currently underway involving researchers at UMCs using SURFnet's E-LAN to create a single virtual UMC with eight locations. Participants in this project include LUMC and SURFsara. The researchers want to connect all UMCs with a private network that has nationwide coverage, allowing researchers from these UMCs to exchange data quickly and securely.
As part of this innovation project, certain aspects related to E-LANs will be investigated further to assess how we can deliver a production service. These aspects include defining and setting up the reporting functionalities and availability of this service as well as investigating how an E-LAN can be integrated with campus networks.
Since autumn 2015, an E-LAN has been available for several pilot projects. Researchers from UMCs are currently cooperating with the help of SURFnet's E-LAN. New pilots can be launched on request.
