The Case for XMPP

By

coversantFriends at Coversant have just released a new white paper capturing use cases, architecture, and lessons learned of their next generation communications and collaboration platform, SoapBox Server. This system is the key to deploying scalable, fast, highly interoperable, secure communications services.

The Case for XMPP

The Industrial Internet requires a persistent connection where the end point doesn’t need to poll the server continually. Extensible Messaging and Presence Protocol (XMPP) was designed to send all messages in real-time using a very efficient push mechanism. Unlike traditional web service API’s, which are unidirectional, XMPP allows bi-directional communication in near real-time without requiring polling schemes or web hosts at both locations.  The presence feature of XMPP enables nodes in the application network to be aware of the states of the other nodes. Endpoint presence changes are pushed, as they happen, to other interested endpoints in real time with the end result being more efficient management of the network. Additionally, the Extensible Messaging and Presence Protocol (XMPP) was designed for large numbers of users behind firewalls and proxies to connect to the internet, so is easily able to scale to 50 million users.

Traditionally used for online chat communication or instant messaging, XMPP has evolved to incorporate features including event publishing, voice streaming, and file transfer. With XMPP an endpoint can be anything—a sprinkler, a sensor, a phone, a toaster, a television set-top box—making it a powerful technology for enabling IoT and Big Data transfer implementations.

XMPP has a decentralized client-server architecture allowing multiple, independently administered servers to be linked together. Using XMPP as the underlying communication protocol for IoT, it is possible to get closer to the ideal of “one network management protocol for monitoring, alarming, configuration, and exchanging policy information, independent of the network,” because application layer gateways can be omitted. The primary goal for bringing XMPP into the IoT vision is to simplify the interconnection of devices.

XMPP message syntax is based on XML and designed to allow application-specific extension enabling anyone to build custom functionality on top of the core protocol. In 2010, Gartner predicted that XMPP would be the standard of communication over the internet by 2015 based on the projected onslaught of devices.

Finally, XMPP is highly secure due to secure Simple Authentication and Security Layer (SASL) mechanisms in addition to Transport Layer Security (TLS) having been included in the core XMPP specifications. As a result, an XMPP server can be isolated from the public network, preventing man-in-the-middle attacks.

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.
With the proliferation of connected devices underpinning new Internet of Things systems, Brandon Schulz, Director of Luxoft IoT – Retail, will be looking at the transformation of the retail customer experience in brick and mortar stores in his session at @ThingsExpo. Questions he will address include: Will beacons drop to the wayside like QR codes, or be a proximity-based profit driver? How will the customer experience change in stores of all types when everything can be instrumented and analyzed? As an area of investment, how might a retail company move towards an innovation methodolo...
Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
Manufacturing connected IoT versions of traditional products requires more than multiple deep technology skills. It also requires a shift in mindset, to realize that connected, sensor-enabled “things” act more like services than what we usually think of as products. In his session at @ThingsExpo, David Friedman, CEO and co-founder of Ayla Networks, will discuss how when sensors start generating detailed real-world data about products and how they’re being used, smart manufacturers can use the data to create additional revenue streams, such as improved warranties or premium features. Or slash...
WebRTC services have already permeated corporate communications in the form of videoconferencing solutions. However, WebRTC has the potential of going beyond and catalyzing a new class of services providing more than calls with capabilities such as mass-scale real-time media broadcasting, enriched and augmented video, person-to-machine and machine-to-machine communications. In his session at @ThingsExpo, Luis Lopez, CEO of Kurento, will introduce the technologies required for implementing these ideas and some early experiments performed in the Kurento open source software community in areas ...

While many app developers are comfortable building apps for the smartphone, there is a whole new world out there. In his session at @ThingsExpo, Narayan Sainaney, Co-founder and CTO of Mojio, will discuss how the business case for connected car apps is growing and, with open platform companies having already done the heavy lifting, there really is no barrier to entry.
As more intelligent IoT applications shift into gear, they’re merging into the ever-increasing traffic flow of the Internet. It won’t be long before we experience bottlenecks, as IoT traffic peaks during rush hours. Organizations that are unprepared will find themselves by the side of the road unable to cross back into the fast lane. As billions of new devices begin to communicate and exchange data – will your infrastructure be scalable enough to handle this new interconnected world?
All major researchers estimate there will be tens of billions devices - computers, smartphones, tablets, and sensors - connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo, November 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be.
The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.
