  1. SES E-VPL Member Deployment for NJEDge.Net Verizon Business Ethernet Solutions Presented By Joseph O’Leary Sales Engineer Higher Education segment for Verizon Business

  2. Ethernet Services - Summary

  3. 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) • 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 Switched Ethernet Service Types

  4. Data Services Network Operations( DSNOC) CPE NID Customer Site B LAN Ethernet Switch Redundant Management Links Service Connection Point IOF 10 M Customer Site A Dedicated Fiber Pair CPE NID Verizon Metro Network Customer’s Virtual Network HQ LAN GigE (1000 M) • Key Characteristics • QoS options available • Shared Ethernet switches • Backbone: Multiple GigE links • Dedicated fiber access • Network Interface Device (NID) • Customer virtual networks (VLAN) 100 M CPE NID Customer Site C LAN Customer Equipment (*MNS Opportunity) EVPL Metro Switched Ethernet Service

  5. EVPL MetroSwitched Ethernet Service Customer network • Customer has three EVPL Premier UNIs and two EVCs, as shown below • EVC-1: single CoS <EVPL-B> = <70 Mbps> • EVC-2: multi-CoS <EVPL-RT, EVPL-PD> = <20Mbps, 50Mbps> Switch port configured as ‘Premier Access Line, untagged’ Switch port configured as ‘Premier Access Line, tagged’ E-UNI 100M SES Network E-UNI 1G CE 6509 6509 NID VLAN-ID=123 EVC-1 A3 A1 VLAN-ID=456 EVC-2 6509 All customer traffic is ‘tagged’ All customer traffic is ‘untagged’ E-UNI 100M A2 Note: For EVC-2, switch looks at {VLAN_ID + CoS (p-bit)} of each incoming service frame - frames must be ‘tagged’

  6. Marking & CoS with SES-EVPL

  7. IP Precedence Unused Standard IPv4 DiffServ Extensions IP Precedence and DiffServ Code Points ToS Byte Version Length Len ID Offset TTL Proto FCS IP SA IP DA Data IPv4 Packet 7 6 5 4 3 2 1 0 DiffServ Code Point (DSCP) IP ECN • IPv4: Three most significant bits of ToS byte are called IP Precedence (IPP) - other bits unused • DiffServ: Six most significant bits of ToS byte are called DiffServ Code Point (DSCP) - remaining two bits used for flow control • DSCP is backward-compatible with IP Precedence • DiffServ Class Selector (DSCS) also uses 3 most significant bits Source: Cisco training material

  8. EVPL Services • Domain • All UNIs in a given domain must be ‘Service Multiplexed’ • Service 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 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 UNI

  9. Local Enterprise, EVPL-EVC, Multiple CoS Customer network • Customer has three EVPL Premier UNIs and two EVCs, as shown below • EVC-1: single CoS <EVPL-B> = <70 Mbps> • EVC-2: multi-CoS <EVPL-RT, EVPL-PD> = <20Mbps, 50Mbps> Service Multiplexed, tagged Service Multiplexed, untagged E-UNI 100M SES Network E-UNI 1G CE 6509 6509 NID VLAN-ID=123 EVC-1 A3 A1 VLAN-ID=456 EVC-2 6509 All customer traffic is ‘tagged’ All customer traffic is ‘untagged’ E-UNI 100M A2 Note: For EVC-2, switch looks at {VLAN_ID + CoS (p-bit)} of each incoming service frame - frames must be ‘tagged’

  10. EVPL Considerations • EVPL is designed for customers using routers to access the service...Bridge CEsmay not work correctly... • All 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 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 UNI • More on this later...

  11. SES EVPL CoS ID, Tagged UNI Service multiplexed UNI, Premier Access Line, Tagged EVC1 • 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 CE-VLAN CoS 5,6 EVPL-RT or EVPL-PD or EVPL-B CE-VLAN CoS 2 UNI EVPL-RT EVC2 CE-VLAN CoS 0 EVPL-PD EVPL-B

  12. CoS Speeds Summary Allowable CoS Speeds per EVC, by Service Type • EVPL CoS Speeds • Low speed: 1 to 9 Mbps, in 1M steps • Medium speed: 10 to 90 Mbps, in 10M steps • High speed: 100-1000 Mbps, in 100M steps

  13. UNI Connection Admission Control (CAC) Rules • UNI CAC rules are built into Provisioning System • Service Multiplexed UNI - see table below

  14. EVPL CoS ID Values

  15. TYPICAL(SEGP): TODAY

  16. TYPICAL(SEGP): TOMORROW

  17. SAMPLE EVC Sizing • EXAMPLE 1: • Today: IP/VPN = 4 Mbps; Internet = 6 Mbps • Tomorrow: EVC/BE= 10 Mbps; EVC/PD = 2 Mbps • Internet Contract: 6 Mbps • EXAMPLE 2: • Today: IP/VPN = 10 Mbps; Internet = 10 Mbps • Tomorrow: EVC/BE = 20 Mbps; EVC/PD = 6 Mbps • Internet Contract: 12 Mbps
