Overview

The network backbone contains a wealth of information that can be monitored and collected to support diagnostic, troubleshooting, and fraud prevention activities. Surveillance of network characteristics is becoming more important than ever before.

Few important aspects of network surveillance include:

  • Performance Monitoring
  • Network Security
  • Fraud Prevention
  • Physical Layer monitoring
  • Billing Verification
  • Remote Protocol Analysis
  • Failure Prediction
  • Traffic Engineering
  • Call Quality Monitoring
  • Troubleshooting

GL’s Passive Network Monitoring and Diagnostic Systems support operators, and service providers to perform all the above functions. The network monitoring systems facilitate real-time analysis, historical storage, retrieval, querying, and display of Call Detail Records (CDRs) by non-intrusively connecting to TDM/Analog, Optical, or IP networks.

System Architecture

GL's NetSurveyor™ system has a three tier architecture. The first layer consists of GL's Protocol Analyzer Probes which are capable of tapping into live call traffic and non-intrusively capture signaling message summary and build CDRs. The second layer is the Database Store Layer where the captured data is stored. The last layer is the Data Access Layer where the data presentation logic is contained. Each of these components are briefly explained below.

Three tier architecture
Digital cross connect
  • Probe computers collecting layer 1 (physical layer), layer 2 (data link layer) and layer 3 (network layer) information. Probes can be T1 E1/T3 E3/ OC-3 STM-1/ OC-12 STM-4/IP.
    • Probe computers run protocol analysis applications along with the necessary hardware and software.
    • These probes could be controlled locally using the protocol analyzer application or remotely using GL's Client-Server application.
    • The analyzer hardware for TDM and optical networks can be connected non-intrusively in Monitor or Bridge Modes, or alternatively the data can be looped through the cards.
    • Multiple Link Sets per T1 E1 (through Digital Cross Connect Grooming) - multiple 64 kbps signaling channels per T1 E1 can be monitored simultaneously by grooming through a digital cross-connect - see diagram below.
    • Probes non-intrusively monitor physical lines of the network and forwards call detail records (CDRs), protocol summary, frame data in hex dump, and statistics to a central database.
    • Probes connect via TCP/IP to ODBC compliant real-time database loader.
    • Only precise and filtered data (user selectable) is collected into the centralized database.

Probe Types –

    • The PacketScan™ is a feature-robust Windows® based software tool that captures and monitors live IP traffic. In the VoIP world, it can monitor and measure SIP, H323, Megaco, MGCP, T.38 and video calls. In the Wireless network, it can monitor 2G, 3G, and 4G protocols such as GSM, UMTS, GPRS, LTE, SIGTRAN signaling over IP. A number of GL’s PacketScan™ probes are deployed in remote locations across the network to passively monitor VoIP traffic.

    • PC based T1 E1 / T3 E3 / Optical probes  collect physical and line level status and performance information. The Intrusive and Non-intrusive "probes" for TDM networks are deployed at strategic locations in a network. They can transmit and collect voice, data, protocol, statistics, and performance information. These probes can relay information to a central / distributed Network Management System (NMS).
  • Database Loader (Data Layer) – A listener application is co-hosted with the database server (SQL DBMS such as Oracle) running on the Data Layer. Interface between the probes and the database is handled by "Listener". The Listener will listen to the streaming data from connected probes, receives data, and feeds the data to DB server.  Multiple probes can be connected via TCP to the Database Loader.
    • Provides load statistics and probe layer 2 status
    • Central control over probes to suspend or resume loading data to DB from connected probes
    • DB stores the data collected by the probes. Records are stored into a relational database (Oracle) using ODBC connection.
    • Listener is modifiable and supportable with MySQL.
  • NetSurveyorWeb™ Webserver (Data Access Layer) serves for data mining operations. The database could be accessed in real-time over the web using applications such as GL’s NetSurveyorWeb™, or queried by customer applications such as a billing system or accessed by a reporting tool such as Crystal Reports, for aggregation and analysis of historic data. The NetSurveyorWeb™ is a user-friendly web-based client which accesses the results provided by the centralized DB through a web server. As depicted in the screenshot below, users can log into the central system locally or remotely to view the collected real-time and historic data including call parameters, layer 1 status display, as well as layer 2 and 3 analysis.

VBA Call Graph and Voice Band Events

VBA Call Graph and Voice Band Events

The Speech Level module with VBA analyzes the captured voice files and produces the following statistics according to ITU Standard P.56. These measurements help detect call anomalies and detect impairments in voice channels in near real-time and thereby quickly remove or rectify the impairing channel from the live network.

The Traffic Classifier module with VBA analyzes the captured files and categorizes the call as voice, fax, and modem data. It outputs the amount of Fax, Voice, Digits, Tones, Silent and Idle traffic present in the network and provides statistics. Traffic Classifier allows Idle Code settings for signaling bits and options to detect DTMF, MF, MFR2-fwd, MFR2-bkwd digits, and Tones (Dial/Ring/Busy).

The Fax Traffic module with VBA process WinPCAP, 2-Wire and 4-Wire voice band capture files to analyze the T.38 packets, T.30 frames. It provides detail decode of a Fax call with TIFF image, and call-flow indicators for complete analysis of fax call. The 2-wire captures are indicated by a single input file, which is presumed to contain the traffic in both directions, as might be captured from a subscriber line. The 4-wire traffic is captured with two input file one containing “east bound” traffic and the other containing “westbound” traffic.
The 2-Wire Line Echo Analysis module with VBA can measure hybrid line echo generated using the captured files at both end points, and generate Echo Return Loss (ERL), Echo Delay, and Echo Dispersion measurement values.

VBA Traffic Classifier KPI
VBA Traffic Classifier KPI

The Tone Decoder module within VBA features a highly efficient FFT module, which can convert a raw captured file to spectrum data. With this module, the VBA can monitor the signal arriving at the receive end, detects, and decodes the tone type as DTMF, MF, Frequency-Shift Keying (FSK), Teletype (TTY), Special Information Tone (SIT), Specific Area Message Encoding (SAME), Voice Mail Waiting Indication (VMWI), Paging Tones, or any Custom Tones from the captured PCM wave file or wave stream. The module also detects and decodes the Type 1 Caller ID, Type 2 Caller ID - Call Waiting (CID-CW), silence, ring-back, busy or other phone tones.

Delay Measurement (OWD)

NetSurveyorWeb™ also works with Delay Measurement tools to analyze captured voice traffic and provide precise one-way delay metrics. For a given call which traverse through Gateway, traffic is sampled at both TDM and IP analyzer at the same point of time running in the same server. These captured segments of SIP and ISDN calls will be saved in *.pcm formats. These samples will be given to delay measurement module which compares the samples based on the timestamp and provides the delay metrics.
