System Summary

Overview

The PTAnalyzer product suite provides continuous 24/7 E2E (end-to-end) service performance management, QoS measurement and SLA supervision to network operators and enterprises. The PTAnalyzer system is a distributed probe based network performance monitoring system and consists of the following components:

• Measurement Probes/Reflectors
• Supervision Domain Controller(s)
• Configuration/Management Client (GUI and CLI applications)

The Supervision Domain Controller (SDC) is the key component in the supervision domain and is responsible for:

• Probe Management
• Session Management
• Analyzes & Alarm Filtering (SLA supervision)
• Auto-Report Generation

SNMP Traps & Database Interface (to external OSS/NMS systems)

A session is an abstraction of a measurement and is responsible to manage the resources, e.g. interacting probes and peers, stream configuration, result reporting. The measurement result is reported periodically to the SDC with a configurable interval. A session has the following properties:

• Active (injecting/receiving) or Passive (listening) mode
• Unicast or multicast addressing scheme
• Multicast channel zapping
• Encapsulations (e.g. UDP, TCP, SCTP, ICMP, GRE, etc)
• Stream Parameters (e.g. bandwidth, packet-size, etc)
• Analyze and Report (e.g. analyze level, report interval, etc)
