Network Instruments Gigabit Observer Suite System (GOSS)
Portable solution to troubleshoot and manage up to 10GbE networks at wire-speed in real time

Network Instruments GOSS Overview
The GOSS contains all the hardware and software required to troubleshoot and manage the most advanced wire-speed networks in real time.

For high-end administrators tasked with travelling to different sites to solve elusive network problems, the GOSS is the only portable unit that provides the technology and capability you need to solve wire-speed, full-duplex gigabit and 10 Gb problems in real time.

When portability counts, the GOSS is the unit you need to manage and troubleshoot gigabit or 10 Gb problems throughout your network. The GOSS includes Network Instruments' own Gen2 Capture Card for complete and accurate gigabit and 10 Gb captures.

The GOSS includes a 64-bit core, maximising analysis with faster processing and larger capture buffers.

Portable, Compact Design

• Fully loaded, the GOSS weighs 11.3 kg
• With case, the GOSS weighs 22.7 kg
• Designed for convenience in travel and shipping
• Includes all necessary hardware and software for real-time, wire-speed analysis

Complete Gigabit and 10 Gb Analysis

• Full-duplex, wire-speed capture
• Real-time metrics and a comprehensive Expert system
• Provides an independent look at data flow
• Passive view — will not interfere with the network

High-Performance

• Ensure accurate captures with Gen2 technology
• Utilise internal Expert probe for collaboration with other consoles

Gigabit Configuration

Switch between optical or copper links with SFP technology
Monitor up to four full-duplex links independently or in aggregate
Gain visibility into trunked gigabit links

10 Gb Configuration

• Provides sustained 10 Gb full-duplex capture at line rate Functions such as filtering and statistics are performed directly on the card
• Provides real-time Expert analysis for 10 GbE networks

The GOSS includes the Gen2 Capture Card and a 10/100/1000 adapter card for complete, wire-speed, full-duplex packet capture, network statistics, trending, real-time Expert, web-based reporting, and an SNMP management system for your network.

Includes an nTAP to Ensure Complete Full-Duplex Captures
The analyser has the ability to perform full-duplex, wire-speed analysis for copper and optical fibre networks. All configurations of the GOSS include an internal nTAP that provides a copy of all traffic to the analyser. In case of gigabit over fibre (i.e. optical) networks, the nTAP splits the optical signal, providing one signal to the network and the other signal to the analyser. In the case of gigabit over copper, the nTAP electronically duplicates the gigabit signal—sending one signal to the network, and the other signal to the analyser. With an nTAP the data flow always remains unaltered and uninterrupted.

In the case of the 10 Gb GOSS, it can include an internal optical nTAP but copper TAPs are sold separately.

Continuous Visibility Into Your Network
The GOSS not only stands on its own as a complete network analyser but also connects as a probe to any Expert Observer or Observer Suite console for advanced troubleshooting across the entire network. With the Network Instruments Distributed Network Analysis (NI-DNA™) architecture all Network Instruments' products can link to each other for complete monitoring and real-time analysis across multiple locations. For example, use the GOSS to retrieve data from any remote probe or to allow a network administrator at another site to access local data. The GOSS not only offers complete portability but also maintains uninterrupted visibility into your entire network.

Proven Analysis Metrics

• Real-Time Statistics such as network summary, bandwidth utilisation, top talkers, and switch statistics.
• Packet Capture and Decode features such as nanosecond resolution, a 24 GB memory buffer (max), and over 550 protocols decoded
• Network Trending and Reporting features such as network trending dashboard display, efficiency history and comparison analysis reports
