Ulticom DSC Release 3.3 - Diameter Signaling. Solved.

MOUNT LAUREL, NJ -- (Marketwire) -- 02/25/13 -- Ulticom, the industry leader in Diameter signaling software solutions for Telecom OEMs, announces Release 3.3 of the Ulticom DSC -- a software product that optimizes Diameter Signaling in 4G and IMS networks.

The Ulticom Diameter Signaling Controller (DSC) enables Service-Oriented Routing™ and multi-vendor interworking between network elements in support of:

  • Centralized Routing - Simplifying network management
  • Load Balancing - Optimizing Charging and Subscriber Data Management
  • Edge Routing - Diameter Edge Agent (DEA) facilitating LTE roaming
  • Policy Routing - Diameter Routing Agent (DRA) advancing Policy Management and Charging

Ulticom's unique Service-Oriented Routing capability goes beyond the typical primary/backup Diameter reliability strategy. The Ulticom DSC serves as a Diameter router and load balancer distributing Diameter signaling traffic across pools of servers. The server pools can be represented to external network elements as a single highly available logical entity -- in effect a Logical HSS, OCS, or PCRF. The Ulticom DSC distributes load across the server pools, provides application specific routing optimization, and dynamically compensates for congestion.

Release 3.3 extends the DSC product with additional advanced routing capabilities. It provides enhanced network routing resilience and even greater flexibility for multi-AVP-based routing. Release 3.3 also provides advanced White Labeling support. This feature empowers OEM customers to rebrand the DSC product and supporting documentation, tailoring it to their own product portfolio.

"White Labeling enables our OEM customers to extend their brand capability while providing the most advanced DSC features in the industry," said Jamie McArdle, Vice President of Sales at Ulticom.

Ulticom's DSC is the industry's most powerful solution for Diameter routing. The Ulticom DSC is supplied as a Linux-based software product deployable on industry popular X86-64 hardware platforms. Ulticom has pushed performance to new levels with Release 3.3. Benchmarked on two HP 380 G8 systems, each running an Ulticom DSC Diameter routing instance, the DSC has been clocked at 864,000 sustained simple Diameter transactions per second (TPS) (equating to 1.8M messages per second or MPS). This same configuration, running the complex Diameter Routing Agent (DRA) functionality, sustains an impressive 580K TPS (1.1M MPS).

Ulticom's DSC provides a powerful, cost effective software solution leveraging Moore's Law for optimal hardware cost/performance over time. The Ulticom solution enables our OEM customers to select the hardware that best meets their particular needs. This enables tremendous flexibility for integrating the DSC with existing OEM product portfolios. Our software based solution also enables our customers to use virtualization and cloud-based solutions to offer signaling services in new and exciting ways.

"Ulticom's DSC underscores our commitment to the evolution of the signaling industry. Smart devices, consumer demand for data centric features, and new network technologies like LTE are placing ever increasing demands on mobile networks. Ulticom is committed to work with our customers to deal with these scaling issues head on," said Bruce Swail, CEO of Ulticom.

The Ulticom DSC is suitable for deployment as a Centralized Router, a Diameter Load Balancer, a Diameter Routing Agent (DRA), or a Diameter Edge Agent (DEA). DEA functionality supports LTE Roaming while DRA functionality provides advanced policy management signaling routing (IP-CAN Binding). The Ulticom Diameter SS7 Gateway (D7G) product provides the ability to interwork between Diameter and SS7 networks -- enabling 2G-3G-4G integration when working in combination with the Ulticom DSC.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...

In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
