The Nokia routers offer the following types of subscriber services which are described in more detail in the referenced chapters:
Virtual Leased Line (VLL) services
Ethernet pipe (Epipe)
This is a Layer 2 point-to-point VLL service for Ethernet frames.
IP pipe (Ipipe)
This provides 7750 SR and 7450 ESS IP connectivity between a host attached to a point-to-point access circuit (PPP) with routed IPv4 encapsulation and a host attached to an Ethernet interface.
See the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 2 Services and EVPN Guide: VLL, VPLS, PBB, and EVPN for more information about VLL services.
Virtual Private LAN Service (VPLS)
This is a Layer 2 multipoint-to-multipoint VPN. VPLS includes Hierarchical VPLS (H-VPLS) which is an enhancement of VPLS which extends Martini-style signaled or static virtual circuit labeling outside the fully meshed VPLS core.
See the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 2 Services and EVPN Guide: VLL, VPLS, PBB, and EVPN for more information about VPLS.
Internet Enhanced Service (IES)
This is a direct Internet access service where the customer is assigned an IP interface for Internet connectivity.
See the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 3 Services Guide: IES and VPRN for more information about IES.
Virtual Private Routed Network (VPRN)
This is a Layer 3 IP multipoint-to-multipoint VPN service as defined in RFC 2547bis.
See the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 3 Services Guide: IES and VPRN for more information about VPRN services.
Circuit Emulation Service (Cpipe)
7750 SR circuits encapsulated in MPLS use circuit pipes (Cpipes) to connect to the far end circuit. Cpipes support either SAP-spoke SDP or SAP-SAP connections.
