Introduction of Next Generation Networks....

The next-generation network (NGN) enables the deployment of access independent services over converged fixed and mobile networks – The NGN is packet based and uses IP to transport the various types of traffic (voice, video, data and signalling).
At the core of the harmonized 'ALL IP' NGN network is the IP Multimedia Subsystem (IMS) which provides an 'access independent' platform for a variety of access technologies (GSM, 3G, 4G, wi-fi, Cable, fibre and xDSL).
Standards for fixed NGN were developed by the now closed ETSI technical committee TISPAN. The TC has adopted the 3GPP™ core IMS specifications using Internet (SIP) protocols to allow features such as Presence, IPTV, Messaging, and Conferencing to be delivered irrespective of the network in use. Maintenance of NGN standards are now the responsibility of TC NTECH.

Computer scientists introduce new graphics software Sophisticated geometric matching, machine learning mimic humans' perception of style, giving users powerful new tools to compare the style similarity of 3-D objects Source:  University of Massachusetts at Amherst   Summary: Computer scientists unveiled a new software modeling program that uses sophisticated geometric matching and machine learning to mimic humans' perception of style, giving users powerful new tools to compare the style similarity of 3-D objects The new first-of-its-kind structure-transcending software can benefit several computer graphics applications, researchers say. FULL STORY As the researchers explain, humans can perceive stylistic similarity between objects that transcends structure and function. For example, we can see a common style such as Danish modern' in both a table and chair, though they have different structures. Until now, machines have found it difficult to do t...

Cloud Computing Trends that will Take 2017 by Storm!

Serverless Computing Server less computing gained traction in 2015  and it became quite prominent in 2016. The good news is that it will continue to beat the charts for 2017 too. Though the term is server less computing, it doesn’t mean that you don’t use servers, it is just that you don’t have to use too many machines or waste resources on idle machines. Server less computing can save operational and infrastructural costs as well. Key players in server less computing are Amazon Web Services with its Lambda platform, Microsoft and IBM.

Chatbots

Enterprise applications of messaging bots seem poised to have a tangible impact on the software space, as more companies invest in developing their own consumer-facing bots. Chatbots, at the most simplistic level, are front-end interfaces for companies to communicate with their customers. More advanced bots leverage artificial intelligence to provide enriching and interactive user experiences. Companies can embed these bots on their home pages, or they can rely on native platforms like Facebook and Slack for distribution. Expect to see companies across all industries, including hospitality, dining and travel, create bots for customer support, sales and marketing services.
