CT Labs Verifies That Acme Packet Supports 1.62M BHCA and 50,000 Concurrent Calls Using Empirix Hammer Test Tools.WOBURN, Mass. -- New Acme Packet Net-Net PAC Proves Leadership in Session Border Controller A Session Border Controller is a device used in some VoIP networks to exert control over the signaling and usually also the media streams involved in setting up, conducting, and tearing down calls. Performance, Availability & Capacity CT Labs and Acme Packet(R) today announced test results for the Acme Packet Net-Net(TM) PAC session border controller in areas of performance, availability and capacity. The tests were conducted using the Hammer NXT NXT Next and Hammer Call Analyzer products from Empirix. Test highlights for the Net-Net "half" PAC with pre-beta software include: --450 call set-ups per second with media using Session Initiation Protocol (protocol) Session Initiation Protocol - (SIP) A very simple text-based application-layer control protocol. It creates, modifies, and terminates sessions with one or more participants. Such sessions include Internet telephony and multimedia conferences. It is described in RFC 2543.

BHCA is the number of telephone calls attempted at the busiest hour of the day (peak hour), and the higher the BHCA, the (BHCA (Busy Hour Call Attempts) The number of times a telephone call is attempted during the busiest hour of the day.

We used the Hammer test tools from Empirix for this test because they provided a highly scalable solution for real world VoIP call scenarios and enabled us to combine transactionally accurate signaling with high density, real media streams," said Chris Bajorek, president of CT Labs. "This test was significant in that the Acme Packet pre-beta results demonstrated a session border controller with very high density call handling capacity, quite possibly the best in the session border controller industry." CT Labs tested an Acme Packet Net-Net "half" PAC consisting of one Net-Net Session Router (SR) and four Net-Net Session Directors (SD). A fully configured Net-Net PAC is a pack of up to nine 1U Net-Net session border controllers - one Net-Net SR and 8 Net-Net SDs and performs as one logical session border controller in 9U of rack space. The Net-Net PAC supports a single, unique signaling interface per peering service provider, enterprise customer or business/residential subscriber group. CT Labs utilized two VoIP test tools from Empirix for the Acme Packet stress test. The Hammer NXT IP(TM), a scalable IP/TDM performance test platform, provided call volume verification, media path confirmation, and voice quality scoring on all calls. The Hammer Call Analyzer(TM), a call and protocol analysis tool that simplifies the debugging of VoIP networks provided SIP call debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. and analysis, real-time QoS metrics, Voice Quality scoring and a multistage mul·ti·stage adj. 1.
