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



Verizon switched ethernet service types

  • 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

EVPL Metro Switched Ethernet Service

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’

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

Evpl services
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

Evpl considerations
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...

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

Cos speeds summary
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


Uni connection admission control cac rules
UNI Connection Admission Control (CAC) Rules

  • UNI CAC rules are built into Provisioning System

  • Service Multiplexed UNI - see table below





Sample evc sizing
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
