To collect the flows of your business clients, it is necessary to first install your connections towards your Points of Presence. Once they are installed, all you need to do is order the accesses that will connect your business clients’ sites by indicating the desired connection for each access’ delivery.

Core Ethernet LAN (CELAN) takes advantage of different Classes of Service (CoS) to meet the various usage needs of businesses. Flows are prioritised and processed within Orange’s network. Prioritisation can happen in real-time or as each access subscription is chosen.

The throughput of data flows for the “voice” and “data guarantee” classes is assured at any moment. This guarantee is no longer provided if the total amount of voice and data guarantee traffic exceeds the capacity of the connection.

The “voice” class uses all the bandwidth required for its traffic to flow smoothly, and is prioritised over the “data guarantee” class.

The throughput of data flows for the “business data” class can reach the level of the access throughput. Data transfer in the network happens at the rate of access that the network load allows.

A BEC connection can collect both BEC and CELAN accesses. For existing BEC connections, a preliminary operation called the “sharing option” must be carried out on the BEC connection.
