Overview:
VOIP Development and Deployment
This Webinar will help both network operators and manufacturers of VOIP and security equipment:

-Minimize the impact of new denial-of-service attacks on VOIP performance
-Improve quality of experience under real-world “data + voice” conditions
-Reduce costs and time-to-market through optimal capacity planning and accurate benchmarking of high-performance network equipment

VOIP Trends
Voice over IP is lowering costs and enabling new applications that integrate telephony into business systems. Manufacturers and service providers are racing to develop and deploy new products to increase the security and performance of VOIP services. Unfortunately, hackers are already writing DOS attacks that exploit weaknesses in VOIP systems, and both service providers and enterprises are finding that security devices can degrade VOIP performance.

New Challenges
Devices such as firewalls, routers, VPN concentrators, VOIP proxies, and session controllers need to allow valid VOIP traffic to pass while simultaneously blocking DOS attacks. These devices must also prioritize voice traffic over other applications to ensure voice quality.

- Network Address Translation (NAT) creates security, performance, and interworking problems for VOIP. Manufacturers are creating several standard and many proprietary approaches for “NAT traversal” – such as STUN, TURN, ICE, UPnP, ALGs, RSIP tunneling, and extensions to SIP and H.323 – that enable VOIP calls to penetrate firewalls and security gateways, often with security compromises and performance degradation.

-VPN tunneling lengthens call setup times and prevents intermediate security devices from inspecting packets. IPSec and IPSecv6 encryption adds voice latency and decreases the ultimate system capacity.

-Denial-of-Service attacks can target the same addresses and port numbers used by VOIP devices and applications. New threats allow eavesdropping. Intrusion prevention devices can mitigate attacks but they can also become bottlenecks. During the Webinar, you will learn how to quantify the impact of DOS attacks on VOIP performance.

-Web Traffic such as HTTP, P2P, instant messagin,g and video streaming can congest networks and degrade VOIP performance through firewalls, edge routers, and other Layers 4-7 devices. In this session, we will help you assess the impact of other Web traffic on VOIP, using real application clients and servers, to ensure that network equipment is capable of prioritizing VOIP traffic under load and meeting QOS requirements.

Integrated Test Methodology and Devastating Results
To wrap up the Webinar, we will introduce a new test methodology that addresses all of these challenges at the same time, allowing you to characterize real-world VOIP performance limits with ease, and show you the surprising results of our own measurement of real devices.
