Spirent's SAPEE platform addresses the ever-changing protocol mix faced by enterprise and cloud computing networks as well as network equipment manufacturers and service providers. This emulation engine accelerates testing by allowing users to quickly and easily add pre-loaded profiles from an extensive library which will initially include applications such as BitTorrent(TM), Peer-to-Peer, Skype(TM), Instant Messaging, database access and other traffic flows.

The concept of delivering a layer 2-7 tool with unlimited protocols and transactions testing capabilities is extremely powerful, said Ahmed Murad, General Manager, Multimedia Applications Solutions Group at Spirent Communications. SAPEE represents the first front-end traffic re-creation solution designed to tackle virtually any requirement by extending the reach of testing into non-traditional, emerging and next-generation protocols as well as the ones already supported by Spirent Avalanche. This combination gives users the means to test all aspects of a content delivery network today without waiting for specific developments to meet their needs down the road.

SAPEE adds to Spirent's holistic approach to data center testing by bringing the realism of live networks into the development and pre-deployment environment. Spirent Avalanche allows network engineers and system designers to generate line rate stateful traffic at multiple 10Gbps capacities, allowing trunk ports to be directly tested.

This tool is the industry's most comprehensive layer 4-7 application testing solution and supports all major protocols, including HTTP 1.0/1.1, HTTPS, FTP, streaming media, IPv6, voice (SIP), mail (SMTP/POP3), DNS, SSL, Telnet, 802.1Q VLAN tagging, IPSec, 802.1x, PPPoE, RTMP, CIFS, networks attacks, and virtually unlimited numbers applications via the SAPEE function.

SAPEE will be showcased during Interop 2009 at Spirent Booth #1051. The solution can also be viewed at Spirent Proof of Concept (SPoC) Labs and Collaboration Centers ( in Beijing, London and Sunnyvale. For more information please visit or follow Spirent on Twitter at
