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) — A Layer 2 point-to-point VLL service for Ethernet frames.
ATM VLL (Apipe) — A 7750 SR point-to-point ATM service between users connected to 7750 SR nodes on an IP/MPLS network.
Frame-Relay (Fpipe) — A7750 SR point-to-point Frame Relay service between users connected to 7750 SR nodes on the IP/MPLS network.
IP Pipe (Ipipe) — Provides 7750 SR and 7450 ESS IP connectivity between a host attached to a point-to-point access circuit (FR, ATM, 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) — 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) — 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) — 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.
