DEDHAM, Mass, October 21, 1998 Harris & Jeffries, Inc. (H&J), a leading developer of networking protocol software subsystems, announced today a comprehensive redundant architecture that provides the foundation for carrier-class, high-availability systems. H&J also announced its first three products developed under this redundant architecture: Soft-ATMTM Signalling Software Subsystem (SSS) Release 2.0, Soft-ATM Integrated Local Management Interface (ILMI) Subsystem Release 2.0 and UltraLinqTM Redundancy Management Software (RMS) Subsystem Release 1.0. The company said future product releases will also incorporate the new redundant architecture.
Network service providers require their network equipment to provide 99.999 percent annual availability equating to about five minutes of downtime per year. This stringent requirement, known as "high-availability," has long been a requirement for traditional telephone switching equipment and has now become a requirement for advanced data network equipment. Network equipment manufacturers satisfy the high-availability requirement by utilizing fault-tolerant, redundant hardware and software architectures.
Soft-ATM's redundant architecture forms a basis for manufacturers to develop high-availability equipment for use by network service providers.
The combination of redundant signalling, ILMI and RMS enables Soft-ATM users to build true "carrier-class" network equipment that can satisfy the needs of the most demanding applications, including core switching equipment.
Redundant architectures assure that steady-state information, such as call state information, is not lost during a failure or an in-service maintenance operation. The impact to transient information such as in-progress call set-up information must also be minimized under these same scenarios. Manufacturers require software synchronization techniques to protect this vital information during failure and maintenance conditions. H&J's redundant software architecture provides manufacturers with the requisite software synchronization techniques that can be used in either a centralized or a distributed product design.
"By employing a redundant architecture in its products, H&J enables manufacturers to bring high-availability systems to market in the shortest possible time. In order to minimize the work required of our customers, we provide a complete redundancy solution that encompasses both subsystem specific and core synchronization functions," said Ethan Harris, president of Harris & Jeffries, Inc. "The redundancy features retain H&J's leading-edge software performance, and with the addition of a redundant architecture, H&J's product line satisfies the most stringent requirements of equipment manufacturers that supply network service providers," Mr.Harris continued.
The redundancy-capable subsystems use structured primitives to hide the redundancy aspect from all other subsystems, thus enabling manufacturers to limit the use of redundancy to just those subsystems that require it. In addition to redundancy-capable subsystems, H&J offers the UltraLinq RMS, an optional redundancy coordinator module that provides the core synchronization functions required by a software synchronization model. H&J's complete redundancy solution operates in conjunction with external system functions to effect a switchover in the case of a failure or maintenance operation.
H&J subsystems are based on an advanced software architecture which provides backwards compatibility and pre-integration of all subsystems. H&J's products include a developer's toolkit, superior service and support and a broad product line that satisfies the most advanced applications. All H&J products include an interoperability guarantee to minimize customers' implementation risks.
Soft-ATM Signalling Software Subsystem Release 2.0, Soft-ATM ILMI Subsystem Release 2.0 and UltraLinq RMS are available now and will begin shipping to customers in December. Pricing of Soft-ATM and UltraLinq products , with the redundant architecture, ranges from $20,000 to $96,000 per product per development license, depending on configuration purchased. Volume discounts are available.
