Run-Time Security and Reliable Delivery of Valuable and Timely Data for LTE Networks, IoT and M2M

Adax SCTP for Telecom (SCTP/T) was designed specifically to meet the demands of LTE and IMS networks. Authentication chunks designated in RFC 4895 secure SCTP-based Associations from packet injection, hijacking or accidental disconnection, thus securing the millions of simultaneous associations required by today’s networks. Steeped in the tradition of telecom reliability and robustness, with thousands of SIGTRAN installations, Adax SCTP/T is ready to meet the challenges in today’s emerging networks, enabling growth and thwarting those with malicious intent.

Specifically designed to deliver telecom quality reliability and performance in IP networks, Adax SCTP/T is the solution to weak and unreliable implementations of RFC 4895 and is the most robust authenticating version of SCTP available. For additional security a DTLS module is available to implement in conjunction with the Adax SCTP/T.

Adax SCTP/T has several other unique advantages over other SCTP implementations:

  • Shorter retransmission timers than RFC-standard min/max values
    • Detects and Corrects errors more quickly
    • Improves destination and peer path failure detection
    • Delivers service comparable to PTSN
    • Meets demands of real-time telecom applications on error-prone IP networks
  • SLQ (Signal Link Quality) Monitors, Analyzes and Acts on path errors
    • Constantly monitors health of all paths in a multi-homed association
    • Analyzes link quality constantly
    • Sends data on all paths when errors are detected on primary
    • Identifies the best possible path for changeover
    • Avoids costly delays of service delivery
  • Supports return to primary for preferred or least cost routes
  • Enables multiple receive threads for non-blocking performance
  • Scales up to 10,000 simultaneous associations
  • Balanced performance and responsiveness across all associations
  • Maintains quality and service for all traffic in the busiest of systems, even low-volume/high-value traffic such as 911 calls, financial transactions, and M2M/IoT
  • Delivers the highest performance, highest capacity SCTP on the market today

 Industry Insight

Service providers are struggling to provide a highly reliable transport mechanism across all network types that maintains the Five 9s reliability that telecom networks demand. Read more here.

What is DTLS?

Datagram Transport Layer Security (DTLS) RFC 6347 is a communications protocol that provides privacy and security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.

A key advantage is that DTLS works in conjunction with SCTP as the underlying transport which means that the application it is providing security for does not suffer from the delays and complexities associated with other heavyweight protocols such as IPsec. DTLS uses the secure authentication extension RFC 4895 provided by SCTP to prevent false associations being started by a malicious attacker.

GTP and SCTP for IoT

As network capacity increases so does the need for performance, security and reliability. Adax GTP and SCTP/T protocol products deliver the capabilities and performance to handle the massive number of connected devices securely and reliably without impacting overall network performance and Quality of Service, thus improving the user experience.
