Your Network Trust, Revealed
February 2007
|
Yesterday’s IT organizations were focused on managing discrete systems. They utilized various niche tools that only trained specialists understood. Today’s IT, and the IT organization of tomorrow, demand a performance management solution with intelligence that supports a holistic view of the network, servers and applications. A key focal point in the solution is a feature that easily communicates to business managers,
in business terms, the status of critical IT services.

Instant Business Service Visibility
Real-time, end-to-end visibility of your IT Infrastructure performance with NetVigil
|
|
Companies collaborate closely with partners across the globe, making high availability and predictable performance of business applications critical. In today’s technology driven business, degraded performance
or outage of an e-commerce service can compromise company revenue. A glitch in the WAN infrastructure could put a halt to an outsourced payroll service. Data intensive collaborative applications or large file transfers could put at risk the quality and reliability of VoIP calls over a converged network infrastructure.

The New Network Challenge: Application Performance Management
Using Sniffer Application Intelligence to Improve Application Performance
|
|
Recognizing that poor application performance is a serious and growing problem, forward-thinking organizations are embracing a new type of application monitoring that brings the sophistication and in-depth analysis of network performance management to the software realm. Called application performance management, it allows network and application professionals to work together to identify and resolve the causes of poor application performance from a network perspective. We will look at:
the economics and challenges of application downtime
best practives for application performance measurement

Optimizing Wide Area Network Performance
Leveraging Sniffer Infinistream across the Enterprise
|
|
Advances in communications technology have allowed more critical business functions to be distributed across these remote sites, relying on wide area networks to ensure mission-critical applications are available. A key problem facing IT infrastructure managers is how to ensure end-to-end network performance and availability as their business increasingly relies on the wide area network (WAN). This white paper provides information on how Ethernet-based network management tools such as Sniffer InfiniStream can:
Simplify the WAN deployment challenge
Reduce the complexity of WAN management
Optimize WAN performance

How Sniffer InfiniStream Complements a Network Security Solution
March 2006
|
|
For any enterprise network, security is a necessity. Whether it’s a single computer at home that has Internet access or a Fortune 500 enterprise network, the information on every hard disk and the data being sent from point A to point B must be secure.
Network General™ has always been dedicated to providing solutions for network and application performance. But did you know that Network General is widely used to protect IT resources and investments? The Network General Sniffer® InfiniStream™ solution can fill the void to add exclusive value to a security environment, and also make the other security components work more effectively. Designed for 24x7 line rate, stream-to-disk capture of 10/100 Ethernet, Gigabit, WAN, and ATM network data, Sniffer InfiniStream allows you to capture full packet network traffic for hours, days, or even up to several weeks.

Convergence of Fault and Performance Management
|
|
Network management systems separately approach 'fault' management, whether something is up or down, from 'performance' management, which is a measure of how well something is working. This document describes the basic features of these two classes of measurements, and how today’s enterprise requirements are forcing them to converge.

Managing Call Flows Using SIP
A technical briefing series on VoIP and converged networks
|
|
This technical briefing discusses the Session Initiation Protocol, or SIP, which is used to manage the call establishment and disconnect procedures within converged networks. SIP, defined by the Internet Engineering Task Force (IETF), has been implemented within a number of systems, including Internet Protocol (IP)-based telephones, IP-based Private Branch Exchanges (PBXs), and carrier networks. SIP provides many of the functions defined in the H.323 standard developed by the International Telecommunication Union — Telecommunication Standards Sector (ITU-T), but with lower complexity and overhead.

Retrospective Analysis: The New Network Management Mandate
Resolving Intermittent Performance Problems Across the Enterprise
|
|
Given the convergence of risk factors - more applications and traffic, network sprawl and lower levels of institutionalized network knowledge - it is clear that new management approaches and tools for network analysis are required. Traditional tools and methods - which are oriented toward the point-in-time capture and analysis of network data or simple best effort monitoring of data - are simply no longer powerful enough to address the complexity of today's network performance challenges.
This 8-page whitepaper highlights the growing importance of a concept called Retrospective Analysis, which combines three critical network performance analysis and problem resolution functions; 1) Real-time, point-in-time analysis 2) Back-in-time analysis 3) Historical analysis.

Building Cost-Effective Security Solutions for Small to Medium Sized Businesses
This whitepaper discusses how network security can be breached; building a secure network and industry accepted tools
|
|
Just because you run a small- to medium-sized business (SMB) doesn't mean you don't have the same network security needs as large corporations. With employees and contractors contributing from home offices, logging in at remote sites, or accessing material from their hotel room, the need to offer continuous security is increasing. Unfortunately, when implementing all the remote access technologies and safeguards, the only difference between enterprises and SMBs is less money and resources.

Core Technology: The OSI Model
A high-level overview for small and medium size businesses
|
|
Have you ever wondered how end-user processes are coordinated between systems and applications? Does it matter to you which layer of the OSI model data packets are encoded and decoded in? What if you could understand how information (data) works in your network? We will look at the:
OSI model
breakdown of the seven OSI layers

Choose Your Wireless
Bluetooth, 802.11b, 802.11a, or 802.11g
|
|
Wireless networking may save you from the physical hassle of connecting computer hardware, but you still have to face the virtual tangle of standards, as well as all of the installation and security considerations.
Combine wireless “anything” with the daily activities and challenges of your business, and you now understand a portion of the issues that small- to mid-size IT operations personnel have to face everyday.

Proactively Troubleshoot and Manage your Small to Medium Size Business Network
This whitepaper discusses a strategy for solving your network problems and providing a practical guide to helping you avoid network downtime
|
|
Network troubleshooting means recognizing and diagnosing networking problems with the goal of keeping your network running optimally. As the IT expert in your small- to medium-size business (SMB), your primary concern is maintaining connectivity of all devices and applications. You also continually evaluate and improve your network‚s performance. Because serious networking problems can sometimes begin as performance problems, paying attention to performance can help you address issues before they become serious.
