Verizon Switched Ethernet Service TypesVerizon Switched Ethernet Service Types
Verizon Ethernet Virtual Private Line (EVPL) Service
– P2P EVC, designed for router CEs– Non-transparent service– ‘Service Multiplexed’ UNI – one or more EVCs
per UNI– Service performance guarantees
E-UNICE(Router)
Verizon Ethernet LAN (E-LAN) Service
– MP2MP EVC, designed for bridge or router CEs
– Connectionless, any-to-any connectivity– Transparent (VLAN tag preservation, L2CP
tunneling) – ‘All-to-One Bundled’ UNIs– Service performance objectives

Two CoS ID options per EVC
• EVC: a given EVC (VLAN ID) –single CoS
• EVC + CoS: a given CoS (p-bit value) on a given EVC – multiple CoS
• Note: CoS ID options per EVC are independent, i.e., both can coexist on same UNI – see right
