Protocol acceleration board boosts performance
Adax has launched the SDCIII AMC, a protocol acceleration board designed to enhance IP network performance by offering packet processing, IP security and signaling capabilities.
Protocol controllers take RTOS onboard
Adax has added the VxWorks real-time operating system from Wind River to the range of operating systems currently supporting Adax solutions.
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 four 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 and Hughes Software Systems have a pre-integrated solution crucial to infrastructure developers suffering pressures to roll out new GPRS/UMTS networks, services and revenue streams.
More support for protocol controller
IntelliNet has completed the integration with Adax's HDC high-density channelised protocol controller to deliver its Accelero application development software and Convero signalling gateway.
Adax SCTP provides hardware assist for both Adler-32 and 32bit 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 "The hardware assist features on the SDCII offload these host intensive tasks, accelerate the IP signalling and maximise the performance of the application for our customers".
The onboard processors on the SDCII perform many thousands of transactions per second, with minimal load on the host CPU, maximising 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 signalling gateway in a single slot solution.
The SDCII is perfect for signalling 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 signalling and security on a single card, delivering on the promise of large cost savings from using SS7 over IP.
