Ethernet Services - Summary

3 Verizon 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 CE (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 E-UNI CE (Switch/Router)

8 EVPL Services DomainDomain –All UNIs in a given domain must be ‘Service Multiplexed’ Service Multiplexed UNIService Multiplexed UNI –Offered only for 100M and 1000M UNIs (not 10M) –Two types: ‘Untagged’ OR ‘Tagged’ (can’t be both on same UNI) –CAC rules apply to UNI...more on this later... EVPL EVCsEVPL EVCs –Customer gets ability to order an EVC with up to three CoS »Separate speeds for each CoS –For EVC order requiring 1 CoS  ‘VLAN ID’ is used to identify the CoS –For EVC order with 2 or 3 CoS  2 options »‘EVC+CoS’ (VLAN ID + p-bit value) »‘EVC+DSCP’ could be used to identify the CoS on the EVC (only for EVCs connecting two untagged UNIs) L2CPs: All L2CPs are discarded at the UNIL2CPs: All L2CPs are discarded at the UNI

10 EVPL Considerations EVPL is designed for customers using routers to access the service...Bridge CEs may not work correctly...EVPL is designed for customers using routers to access the service...Bridge CEs may not work correctly... All traffic is policed on these UNIs  CE can’t burst to line rateAll traffic is policed on these UNIs  CE can’t burst to line rate CE must police/shape traffic to coordinate with the Bandwidth Profile of the serviceCE must police/shape traffic to coordinate with the Bandwidth Profile of the service –Traffic exceeding the BWP is dropped by the policer –More on this later... Connection Admission Control (CAC) rules limit the number of EVCs and the aggregate bandwidth per CoS on a given UNIConnection Admission Control (CAC) rules limit the number of EVCs and the aggregate bandwidth per CoS on a given UNI –More on this later...
