Managing Application Delivery

Understand the existing and emerging issues that can impede application delivery including managing virtual and multi-tiered environments and develop a coherent strategy for overcoming delivery issues and ensuring application uptime. From Jim Metzler of Ashton, Metzler & Associates.

ROI for Network Performance Management

Understand the business value of infrastructure equipment and management technology investments while learning the components needed to make a business case for investing in this technology. From Enterprise Management Associates.

Monitoring Service Delivery in an MPLS Environment

Many organizations now use MPLS routing to ensure critical applications have the required bandwidth. Sophisticated MPLS-enabled analyzers can help you understand and troubleshoot your MPLS network issues to guarantee it operates to its full potential.

Monitoring and Managing Network Application Performance

Effectively managing application performance means measuring how well key components of the IT infrastructure are performing over time. This expert application analysis is a must-have in any administrator�s toolbox.

Monitoring and Managing Voice over Internet Protocol (VoIP)

VoIP’s sensitivity to delay and packet loss compared to other network applications such as web and e-mail services, presents a real challenge. Learn best practices for keeping your VoIP network flowing smoothly, your time-to-resolution low, and end users happy.

Implementing Unified Communications

Laying the proper groundwork for implementing and configuring unified communications is important to avoid performance problems. Get a basic knowledge of the technology and understand what needs to occur before deployment and what to do once it has been implemented.

Extending Network Visibility by Leveraging Flow Technologies

Manufacturers have embedded NetFlow and sFlow® technologies into enterprise-level switches and routers. Learn the strengths and limitations of these technologies and how to provide extended visibility without over-extending the IT budget.

Retrospective Network Analysis

Network engineers can spend large amounts of time replicating intermittent problems or enforcing security and compliance regulations. A retrospective analysis solution allows for the reconstruction of a failure or attack, rather than simply monitoring in real time, while providing a significant time and cost savings to the organization.

Security Forensics

As security threats grow in complexity and organizations face stringent regulatory requirements to audit access to private data, organizations require an increased level of network visibility and surveillance. Learn a new method of capturing and storing every packet travelling over your network.

WAN Monitoring

A WAN analyzer offers essential insight into your WAN links through WAN frame visibility, performance metrics, and problem resolution capabilities. However, there are several items to consider when reviewing WAN analysis options.

Preparing Your Network for Cloud Computing

While providing increased IT flexibility and potentially lowering costs, cloud computing shifts IT management priorities from the network core to the WAN/Internet connection. Learn the basics of cloud computing as well as best practices to prepare your network.

Remote Monitoring

You need visibility into every corner of the network, from the edge to the core. Read examples of how to plan and implement a monitoring/analysis infrastructure based on distributed probes.

Virtual Traffic Monitoring

As organizations implement virtualized environments, knowing how to monitor and maintain them becomes yet another challenge. This white paper presents various visibility options for monitoring a virtualized environment.

Network Instruments Puts Virtualized Systems on Tap

Virtualization creates another layer of abstraction. Learn how Network Instruments is at the forefront of addressing the key challenges of fully embracing virtualization fully. From Enterprise Management Associates.

Analyzing Full-Duplex Networks Through SPANs, Port Aggregators, and TAPs

There are several ways to access full-duplex network traffic for analysis: SPAN or mirror ports, port aggregators, and TAPs are the most common. It is important to understand the relevant issues before choosing a technology to deploy on your network.

SNMP Monitoring: One Critical Component to Network Management

SNMP remains a critical part of a complete network analysis solution. For truly comprehensive analysis of network issues, a network analyzer with packet capture capabilities should be employed.

Network Instruments� Observer and VLAN Analysis

IT departments continue to implement Virtual Local Area Networks (VLANs) to contain broadcast traffic, load-balance, and enhance data security. A VLAN-ready network analyzer provides several benefits in managing VLAN configurations.

Using a Network Analyzer as a Security Tool

Learn how using a network analyzer can enhance network security, which analyzer features are essential for this task and how an analyzer should be part of any IT professional�s security incident response plan.

Network Instruments� Observer and Sarbanes-Oxley Compliance

Sarbanes-Oxley Act of 2002 (SOX) extends beyond the accounting department — complying with SOX requires cooperation and support among many business units, including IT. Learn how Observer can support IT�s role in SOX compliance.

Observer Infrastructure: Adding the Device Performance Perspective

The focus of networking professionals has turned toward network performance and optimization. Learn to build complete performance visibility by adding the infrastructure perspective to a packet-based platform. From Enterprise Management Associates.
