12 Network services ServiceDescription Layer 1 Provides a physical layer (i.e. layer 1) service between customer sites belonging to the same VPN. Connections can be based on physical ports, optical wavelengths or TDM timeslots. Layer 2 Provides at data link layer (i.e. layer 2) service between customer devices belonging to the VPN. Forwarding of user data packets is based on information in the packets' data link layer headers, e.g. DLCI, ATM VCI/VPI, or MAC addresses Layer 3 Provides a network layer (i.e. layer 3) service between customer devices belonging to the VPN. Forwarding of user data packets based on information in the Layer 3 header, e.g. IPv4 or IPv6 destination address.
