Service Assurance Features (Con't)

•OAM Functionality

–IEEE 802.3ah Ethernet OAM

–IEEE 802.1ag Service Layer OAM (Connectivity Fault Management)

–ITU-T Recommendation Y.1731

•Dying Gasp (via 802.3ah or SNMP traps)

•VLAN Tagging/De-tagging and VLAN Stacking (.1Q in .1Q)

•Integrated Copper TDR cable integrity testing

•Optical Digital Diagnostics (SFF-8472) with threshold crossing alerts via SNMP traps

Performance Assurance Agent

• Continuous in-service monitoring of Layer 2 & 3 SLA parameters, unicast or multicast

– One-way and Round-Trip Latency (Delay)

– One-way and Round-Trip Jitter (Delay Variation)

– One-way Packet Loss

– Continuous End-to-End path continuity check, Availability (SES)

– IGMP Group join / leave delays

• High Precision measurements

– 1 μs resolution

• Exclusive remote synchronization allows highly accurate one-way measurements over large geographical areas. Optional GPS not required for 1-way measurements, but may be used as a timing/sync source.

• Large-scale performance assurance works in multiple topologies:

– Point-to-Point Multipoint-to-Multipoint Mesh

• Assures SLAs per VLAN/per CoS/per ToS/per EVC

• Multi-SLA™ monitoring –up to 100 simultaneous instances

• User settable SLA threshold crossing alerts using SNMP traps

RFC-2544 Testing & Traffic Generation

• Wire-speed Traffic Generator and Analyzer

– Layer 2 or Layer 3 (IP)

• In-Service Traffic Generator and Analyzer (2)

– Layer 2 or Layer 3 (IP) Unidirectional or Bidirectional

– Seamless operation, does not affect customer traffic

– Up to full service or Wire-speed 1 or 2 test streams

• RFC-2544 Automated Test Suite with reports (1)

– Throughput Frame loss Back-to-Back

– Delay (Latency)

– Delay Variation (Jitter)

– Supports all packet sizes including Jumbo Frames

– Automatic report generation
