New Generation of Signaling Controller Cards To Meet The Demands of IP Signaling and Security
Hardware Acceleration for SCTP, SIP and IPsec on the same card

16 February 2005, 3GSM, Cannes, France: Adax has announced a new generation of signaling controller that meets the high processing demands of IP signaling and security. Specifically designed to handle the increased demands of IP convergence, the new Adax SDCII delivers high performance SIGTRAN protocols and native IP signaling in a PMC card format. The hardware assist features of the SDCII accelerate the performance of SCTP, SIP and IPsec.

The Adax SDCII-PMC card delivers high performance SCTP across 4 GigaBit Ethernet ports for high volume SIGTRAN and SIP applications. The Checksum Processing of outbound and inbound SCTP PDUs is taxing on the application CPU and can be responsible for up to 30% of the protocol overhead. Adax SCTP provides hardware assist for both Adler-32 and 32-bit CRC checksum so that the checksum computation is performed on each outbound and inbound PDU by the dedicated hardware on the SDCII board.

Hardware assist can also be used to implement IPsec which is a set of IETF protocols that provides encryption services for IP network traffic to support the secure exchange of packets at the IP layer. The big advantage of IPsec is that the encryption services are transparent to the application but this places a large burden on host processor effecting application performance. Implementing IPsec on the SDCII board removes the encryption and decryption overhead from the host and improves system performance.

“The processing overhead from SCTP, SIP and IPsec can severely impact the performance of the host CPU and the applications running on it”, said Barry Zuckerman, President of Adax Inc. “The hardware assist features on the SDCII offload these host intensive tasks, accelerate the IP signaling and maximize the performance of the application for our customers.”

The on-board processors on the SDCII perform many thousands of transactions per second, with minimal load on the host CPU, maximizing the performance of network applications for customers without compromising reliability and providing a totally scalable, flexible and cost-effective solution. The SDCII can be used in conjunction with the Adax HDCII card for SS7 and integrated on a Single Board Computer (SBC) to provide a complete high density SS7/IP Signaling Gateway in a single slot solution.

The SDCII is perfect for Signaling Gateways, Media Gateway Controllers (MGCs), and Next Generation Nodes such as SGSNs, GGSNs, MSCs, HLR/VLRs, and BSS. The card’s excellent performance allows operators and service providers to meet the high processing demands of IP signaling and security on a single card, delivering on the promise of large cost savings from using SS7 over IP.
