HORSHAM, Pa. -- Today Delta announced the formal release of a new generation of software based Voice and Video over IP test tools. The successful beta test phase culminated in a widely heralded public demonstration of the suite at VON2003. The new suite of software-based tools includes H.323 and SIP call generators and protocol analyzers that run on the Windows 2000/XP/Server platforms. By developing our own protocol stacks which are optimized for the test environment, the tools achieve high performance at very low cost, providing equipment manufacturers and service providers with the cost effective tools they need to deploy the evolving Next Generation Networks.

The suite includes enhanced versions of the WinSIP and Win323Gen call generators and the new Win323Mon voice and video over IP protocol analyzer. With pricing starting at under $10,000 for the call generators and under $5,000 for the protocol analyzers, the tools yield the highest performance to cost ratio in the industry. Each tool is available as either a downloadable software application or as a pre-packaged test instrument.

The Win323Gen and WinSIP call generators feature robust bulk call generation for capacity testing network equipment with high call volumes including media streams. The win323Mon tool is a real-time voice and video protocol analyzer that delivers comprehensive protocol and packet analysis with full decoding of the H.323 protocols. The new suite of software-based tools compliments the current Delta emulators and analyzers that are in constant use by major equipment manufacturers around the world to shorten the product development cycle through effective troubleshooting and diagnostics. By combining the new suite of tools with the existing tools, the test and design engineers are able to extend their testing to include capacity and load testing for verifying throughput and stability of the products prior to their release to the customers.

Product Descriptions

WinSIP – High output SIP bulk call generator with ultra fast SIP signaling

WinSIP is a high performance, scalable, low cost SIP bulk call generator that runs on standard PC hardware. It is a cost effective test tool with performance that rivals more expensive solutions that require highly specialized hardware to achieve similar results. WinSIP provides RFC 3261 compliant SIP signaling and media load generation for both voice and video over IP calls. It allows you to construct test scenarios which model the real world environment, including 3GPP, by giving you the flexibility to control all aspects of the calls. Call files and individual call attributes can easily be modified or fine tuned using a simple, familiar spreadsheet style interface.

New features include a completely redesigned, high performance SIP stack based upon the RFC3261 specification of the dialog/transaction model, automatic answering of inbound calls on the well known port, finer granularity of call durations and call start delays, TCP/IP support, and other features. The new version provides over 50% higher throughput than version 1.0 of WinSIP. The new WinSIP provides automated call-flow tracing for an entire session with a breakdown of the messages, dialogs, events, and transactions.

Win323Gen – High output H.323 bulk call generator with flexible call modeling

The high performance Win323Gen bulk call generator emulates high volumes of H.323 calls with real-time signaling and payload data for H.323 Voice and Video over IP applications. An easy to use GUI provides the user with fast profiling of the calls. The Win323Gen test tool is used to test system and network capacity, performance, and provides packet analysis of the audio and video media streams. Win323Gen’s intuitive user interface allows you to generate test profiles containing thousands of calls in less than one minute.

New features include higher performance with increased call capacity (number of concurrent calls and call rate), streamlined call file generation, options to run with and without media, call rate distribution specification, and QoS monitoring on received media streams. Alarms are set by the user to monitor multiple thresholds for audio and video jitter and latency.

Win323Mon – H.323 protocol analyzer

The new Win323Mon protocol analyzer is an H.323 protocol specific analyzer that provides smart diagnostic capability with real-time breakpoint event processing. Alerts and alarms that are specified by the user provide live analysis and capture of H.323 specific protocol events “on the fly”. The analyzer also provides call association by call id and conference id along with advanced filtering of the H.323 protocol layers. A multipoint conference is analyzed as a collective group of calls so the user can easily trouble shoot each call within the conference. Additional features include RTP decoding and analysis for Qos metrics such as latency, jitter, packet loss, R-factor, and video frame rate.
