  40. LA-210 Flow Concept

  41. LA-210 Flow Based Forwarding Model Up to 8 flows UNI NNI Policer per CoS CoS 7=BW profile5 Flow 2 Flow 1 (EVC 1) CE-VLAN : 555 p.bit 7 777 p.bit 4 Policer per CoSCoS 4=BW profile3 Classification by Flow Key per port Editing Adding SP-VLAN Marking CE-P.bit  SP-P.bit Flow 1 (EVC 1) CE-VLAN= 1 CoS per Flow Flow 1 = CoS 3 Policer per CoS CoS 3=BW profile 1 By CoS Step 1 – Flow Classification Step 2 – Flow Mapping: Defines VLAN members per flow Step 3 – Assigning Fixed CoS per Flow/CoS per P.bit Step 4 – Policer Per CoS: Define the CIR/EIR/CBS/EBS Bw criteria per CoS Step 5 – Configuring Strict or WFQ priority, according to user configured profiles. Note Priority Queues are fixed to CoS. Step 6 – P. Bit priority marking: Adding the P.bit to the SP-Vlan, according to user configured profiles.

  42. Mapping User Traffic to Services • On user ingress – traffic is mapped to Service by one of the following criteria: • P.Bit • VLAN ID • IP Precedence • DSCP Layer 3 Frame Structure Layer 2 Frame Structure 1 2 3 4 5 6 7 8 IP Precedence C-VLAN ID C-Priority Bit DSCP

  43. CoS/Services Mapping CoS/Services 6 CoS Mapping criteria: • P.Bit 4 7 7 5 CoS/Services 7 3 6 EVC1 EVC1 38 4 • VLAN ID EVC2 EVC2 UNI 2 22 0 VID6 VID6 EVC3 0 1 VID7 VID7 0 Layer 3 Frame Structure VID’s + P.bit: 10 / 5 15 / 3 CoS/Services • IP Precedence/DSCP 1 2 3 4 5 6 7 8 3 IP Precedence DSCP

  44. Policer Per Service/Flow Bandwidth Control • Traffic policing per ingress Service • Dual Token Bucket mechanism (CIR+CBS, EIR+EBS) per policer • 2 rate (CIR/EIR), 3 color (Green/Yellow/Red) marking: • Green:0 to CIR – always ‘respected’ • Yellow: between CIR to EIR – Will be respected until the queue reaches a predefine threshold, then it will discarded • Red: above EIR – always discarded EVC1 EVC2 UNI EVC3 CoS 7 EVC2 CoS 4 CoS 1

  45. Queues/Egress Rate Limit/Scheduler • MNG Traffic Always get the Highest Queue • 4 Queues on the Egress (4th Q has the Highest Priority) • Each Queue can be configured as Strict/Weighted Fair Queue (100 Weights) • Egress Rate Limit per Queue/Port (DSL) • Scheduling: • Strict on Top of WFQ • WFQ (Weight of Q) ÷ (Weight of all Q) • Example: Queue #2  40 ÷ 80 = ½ Queue #1  30 ÷ 80 = 3/8 Queue #0  10 ÷ 80 = 1/8 MNG 4 Strict 3 Rate Limitation/Shaping WFQ=40 2 Scheduling 1 WFQ=30 WFQ=10 0

  46. Editing And Marking • Editing the SP-VLAN ID towards the network • Stack • None • Marking the Flow Priority on the Egress according to: • P.Bit (802.1p) • IP Precedence • DSCP SP-100 P.Bit 7 VID’s: 10,15,20-30 Editing And Marking SP-200 P.Bit 3 Network Unclassified Editing And Marking

  48. Continuity Check (CC) OAM Customer Premises Customer Premises • CC OAM Defined per EVC, allows for one-way connectivity monitoring • Loss of Continuity (LOC) is declared (only at the sink side) upon 3.5 seconds without receiving CC OAM frame • Loss of Continuity (LOC) is cleared upon sink receiving 2 CC OAM frames within a window of 3.5 seconds • Upon CC failure • Send trap • Update active alarm log • Update statistics • Optional uplink switch-over CPE E-NTU E-NTU CPE Operator B Operator A CC Sink CC Source CC OAM Frames

  49. Loopback (LB) OAM Customer Premises Customer Premises CPE E-NTU E-NTU CPE • Defined per EVC,allows for non-intrusive loopback (round trip) connectivity monitoring • Sent from MEP, looped by either MEP or MIP • LB Failure is declared upon 2 seconds without receiving the specific LB OAM frame • Upon LB failure • Send trap • Update active alarm log • Update statistics • Optional uplink switch-over Operator B Operator A LB OAM Request LB OAM Reply Service OAM MEPs and MIPs
