2 First a Health Warning...

3 About Network Instruments Privately held Founded 1994 Focus on Network Performance Management 20 offices worldwide 130 partners across 50 countries Key Products Observer GigaStor 23% average annual growth for past ten years

4 Keys to Ensuring Network Performance Critical Challenges Virtualisation The Cloud Unified Communications Increased application responsibilities Performance Management Keys Moving at data centre speeds Virtual visibility Monitoring through the cloud Preparing for the UC surge In-depth application awareness

5 Virtualization One Server Hosting many virtual servers Saves rack space Saves time and money Greener Main supplier is VMWare, w ith many competitors Sources:: Forrester Research, EMA Inc

6 Virtualization All companies are rapidly virtualising servers 55% of firms will have implemented by 12/09* Additional 29% planning budget for virtualization Major changes New connected elements (VMs) New netw ork elements (vsw itches, vnics) New topological constructs Challenges for IT managers Loss of visibilit y int o: Topology changes Within a hypervisor and VM -to-vm Loss of cont rol Unclear responsibilit ies New and unclear boundaries Sources:: Forrester Research, EMA Inc

8 The Cloud Cloud computing is Web-based processing, whereby shared resources, software, and information are provided to computers and other devices (such as smartphones) on demand over the Internet. Examples: Salesforce Google Applications Many, many others

10 The Cloud Gartner's 2010 CIO survey identified cloud computing as the No. 2 strategic technology investment for CIOs globally Major challenges Loss of visibility w ith most processes taking place on another netw ork Proving points of delay/ failure: internal netw ork, ISP, or cloud vendor IT operations need visibility into cloud environments Monitor performance and availability Enable metering and billing Integrate with enterprise management systems

11 Unified Communications UC combination of , messaging, telepresence, VoIP, video According to Cisco: By 2013, video (TV, VoD, Internet video, and P2P) w ill exceed 90% of global consumer IP traffic Video communications traffic increase 10x 2008 to 2013 Preparing for the video conferencing bandwidth hog Single telepresence suite requires 5 Mbps dedicated bandw idth Low end requires 5-10x bandw idth of typical VoIP calls Delay or outage is a major issue Bottom line for network managers UC does not represent major change vs existing applications Video requires added planning, policy, quality monitoring and t roubleshoot ing Monitor and set the boundaries

12 Increased Application Responsibilities Trends 80% of application failures blamed on network problems, but networks will be less than 20% of the root cause* User experience and business services hinge on application performance Web enabled applications Challenges Increased layers and platforms to monitor Easier for customer to walk out of your shop Rate of change will be constant Source: Gartner. David Cappelli and Debra Curtis. 14 May Polling Results Show Data Center Network Managers Increasingly Being Tasked With Meeting Application Performance Goals.

13 Performance Management Requirements

14 Moving at Data Centre Speeds Dropped packets = unresolved problems, especially in UC Ensuring validation of new technologies requires Reliable 10 Gb capture Large volume of data storage Rapid search to locate root cause Same size needle, larger haystack

15 Virtualization Virtualized environments create black holes for ill prepared Need visibility into VM-to-VM communication, even on same physical host Example: Multi-tiered applications Cannot analyse with tools that cannot be virtualized Ensure integrated visibility into physical and virtual environments

16 The Cloud Tools used to manage cloud services are often similar to tools used to manage internal infrastructures Verify ability to track and analyze conversations from user to end destination in the cloud Need in-depth WAN/Internet performance monitoring metrics: SLA enforcement Tracking precedence Locating and proving source of the problem: internal network, ISP, or cloud provider

17 Unified Communications Solutions need visibility to validate performance UC-specific metrics Jitter, quality, precedence settings, etc View UC w ithin context of overall netw ork traffic Separate Netw ork and UC problems

18 Increased Application Complexity No brainer: It s not the network, it s the application Need application-specific metrics and information Integrate multiple monitoring perspectives Packets, NetFlow, SNMP, WMI, WAAS, NBAR Automated expert analysis Baselines and intelligent alarms Complete packet capture for problem resolution
