Agilent Helps Deliver Enhanced Network Services with Network Tester

6/3/2003 - Agilent Technologies Inc. (NYSE: A) introduced the Agilent N4180A Network Tester, designed to accelerate the development and deployment of connection- and content-aware devices that enable delivery of enhanced network services, including firewalls, intrusion detection and prevention systems, and virus/URL/SPAM filtering gateways.

Highly scalable, the Agilent N4180A Network Tester emulates millions of clients and servers and includes generation of HTTP traffic at rates of up to 15 Gb/s and 300,000 gets/s per system chassis, for performance testing of transport- and application-aware (L4-7) devices. Furthermore, Network Tester is unique in its ability to generate test traffic that runs over a true TCP stack, and is highly scalable, realistic and complex.

The Agilent Network Tester can also be used for testing content switches and load balancers, SSL VPN accelerators, and Web and NAS servers. It allows equipment developers and enterprise and public network operators to easily and quickly load and stress new products with real-world, multi-protocol, Internet-scale traffic, under a wide variety of user-definable scenarios.

Developers can reduce development costs and cycles by identifying functional performance problems prior to product release. Network operators can use the system to verify capacity and performance claims, perform multi-vendor evaluations and identify potential traffic issues in their labs, prior to deployment.

"Today, the inclusion of security-related service enhancements, such as virus filtering, intrusion detection and firewall protection, has become a necessity for network design," said Dave Bass, vice president and general manager of Agilent's Data Networks Division. "The new Agilent N4180A Network Tester enables users to evaluate the effectiveness of these security features on networking devices, and to measure their impact on overall network performance as traffic loads are scaled up, under a variety of user-definable real-world scenarios."

Up to three chassis can be combined in one system, with each chassis providing up to 34 10/100/1000 Mbps Base-T Ethernet test ports, or 106 test ports in total.

A graphical user interface and shared object-oriented environment simplify multi-user design, editing and management of test plans. Traffic profiles and protocol combinations can be graphically defined, saved and edited to speed creation of complex test scenarios.

The product supports a wide variety of TCP/IP protocols, including HTTP, HTTPS, FTP, SMTP, POP3 and DNS. High rates of DoS attack and normal client/server traffic can be generated simultaneously to test network performance and device security. The system can be used on a standalone basis, or connected to a LAN to permit multiple users to perform concurrent remote testing.

The N4180A/N4181A/N4182A Agilent Network Tester can be purchased as a complete initial system, or as individual chassis and 10/100/1000 Base-T Ethernet blade units. All components are available for shipping now. Further information is available at
