EVPL MetroSwitched Ethernet Service

• Customer network
• Customer has three EVPL Premier UNIs and two
  EVCs, as shown below
• EVC-1 single CoS ltEVPL-Bgt lt70 Mbpsgt
• EVC-2 multi-CoS ltEVPL-RT, EVPL-PDgt lt20Mbps,
  50Mbpsgt

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

• 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 (cant 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
• EVCCoS (VLAN ID p-bit value)
• EVCDSCP 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

Local Enterprise, EVPL-EVC, Multiple CoS

• Customer network
• Customer has three EVPL Premier UNIs and two
  EVCs, as shown below
• EVC-1 single CoS ltEVPL-Bgt lt70 Mbpsgt
• EVC-2 multi-CoS ltEVPL-RT, EVPL-PDgt lt20Mbps,

EVPL Considerations

• 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 cant
  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...

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
Allowable CoS Speeds per EVC, by Service Type
Class of Service (CoS) EVPL Services Premier Access Line EVPL Services Premier Access Line
Class of Service (CoS) FE (100M) GE (1000M)
Real-time (RT) 1-50 Mbps 1-100 Mbps
Priority Data (PD) 1-50 Mbps 1-500 Mbps
Basic (B) 1-100 Mbps 1-1000 Mbps

• 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 CAC rules are built into Provisioning System
• Service Multiplexed UNI - see table below

CAC Rules for Service Multiplexed UNI CAC Rules for Service Multiplexed UNI CAC Rules for Service Multiplexed UNI CAC Rules for Service Multiplexed UNI CAC Rules for Service Multiplexed UNI CAC Rules for Service Multiplexed UNI
