Diameter-BRICKS

Enea Netbricks Line of Protocols for NGN and IMS Applications

Enea offers a wide range of highly portable telecom protocol stacks for TDM, 3G, IMS, and NGN networks, as well as fax and data transfer protocols and signal processing and analysis software. All Enea Netbricks protocols stacks are compliant with ITU, ETSI, ANSI, IETF, 3GPP, and many other standards bodies’ specifications. 

All of Enea Netbricks protocols are written in ANSI C and take advantage of a modular, portable architecture that allows hardware platform and compiler independence. Enea Netbricks protocols are provided in source code to over 400 network equipment providers (NEPs), and device OEMs worldwide, assisting them in getting products to market quickly, with very low risk and significantly reduced development costs.

  • Portable protocol stacks compliant with protocol standards as published by the key standards bodies around the world (ITU, ETSI, ANSI, IETF, 3GPP).
  • Supplied as source code.
  • Used by over 400 global, industry leading telecommunications equipment manufacturers and OEMs.
  • Backed by over 20 years of protocol development expertise and 40 years of telecom software expertise.

DIAMETER-BRICKS is a source code implementation of the AAA protocol suite as specified by the IETF AAA Working Group.

DIAMETER-BRICKS is a signaling protocol that has been specified by IETF to perform AAA (Authentication, Authorization and Accounting) functions in IMS (IP multi media system) next generation networks. It has also been adopted by 3GPP and 3GPP2 standardization bodies for AAA in IMS mobile systems and networks and is designed to perform these functions in both local and roaming (ROAMOPS model) situations.

DIAMETER-BRICKS has been designed to ensure as much as possible backward compatibility with RADIUS (Remote Authentication Dial In User Service) protocol widely deployed in current intranet and internet configurations. It introduces many enhancements in order to address several RADIUS shortcomings and deficiencies such as no end-to-end security, limited size of length and identifier fields, limited failure detection mechanism.
