Service types provide the traffic adaptation needed by customer attachment circuits (ACs). This (logical) service entity adapts customer traffic to service tunnel requirements. A VLL service is a point-to-point MPLS-based emulation service, also called Virtual Private Wire Service (VPWS). The 7705 SAR-Hm series provides Ethernet VLL (Epipe) service and BGP VPLS-based Layer 2 service.
The series also provides Ethernet layer (MAC-based) VPLS service (including management VPLS), raw socket IP transport service, as well as IP layer VPRN and IES services, that offer any-to-any connectivity within a Virtual Routing Domain or Generic Routing Domain, respectively.
