Chapter 10: Packet over SONET Modules
POS-3500/3502 Series Modules
140 SmartBits System Reference
Features: • Up to 8,192 independent IP streams (peer-to-peer) generated and analyzed at any
given time. Up to 64K individual flows may be instrumented per stream. A total of
524 million flows is supported.
• SONET/SDH Overhead analysis of Section OverHead (SOH), Line OverHead (LOH)
and Path OverHead (POH).
• SONET/SDH payload scrambling enabled under user control (X43+1).
• User-selectable Frame Check Sequence (FCS) of 16- or 32-bit.
• IP traffic encapsulated over PPP (as per RFC 1662) or over Cisco’s HDLC with
Ethertype.
• Individual control of each stream allows for frame size (40 to 64K bytes), frame rate,
and transmission mode control (continuous, single-burst, multi-burst, continuous
multi-burst) setting.
• 1MB capture buffer enables logging and exporting of filtered events to external
protocol analysis equipment.
• Full SmartMetrics testing capabilities include sequence tracking per stream, latency
over time, latency per stream, and latency variation.
• Unicast and broadcast traffic effects may be analyzed. Additional analysis capabilities
include data integrity checking of payload and IP header checksum verification.
