Software defined networking (SDN) is one of the key technologies driving the transformation of the next generation networks. To begin with, SDN was just a mechanism to “separate out control from data”. The logic to control the network was moved to a centralized controller. This allowed the operators to program the network on demand, from one point of control. Further, it allowed them to set rules/configurations across devices, from different vendors in a unified way, without manual intervention. These flexibilities proved to be a huge improvement over traditional networking where provisioning/configuration was done on individual basis and a single failure in the network could lead to huge downtimes. The notion and scope of SDN applicability in networks has considerably transformed since then. Traditional networking using distributed routing protocols are focussed on the needs of the basic network; route discovery, link failure recovery, etc. However, these services by themselves don’t fulfil the requirements of emerging technologies like IoT and MEC – handling multi-vendor devices, heterogenous networks (Wi-Fi, Bluetooth, ZigBee, LTE), huge amount of data, faster deployments, management of services etc. SDN promises to deliver an agile and flexible network infrastructure, to handle varying user-demands and diverse network scenarios.
Communication technology has been evolving at a fast pace for past two decades. During this time, wireless technology has also gone through many changes. From 3G and 4G, now we have companies expecting and preparing for 5G wireless technology. It’s the fifth-generation technology that might not have arrived yet, but OEMs have already started to make 5G enabled equipment.
There is a dire need for quality Wi-Fi services, all over the world. As wireless technology continues to escalate, an estimated 200 billion wireless devices will be operational by 2020. In addition to that, carrier Wi-Fi hotspots are likely to reach 13.3 million by the same year. Both businesses and individuals are searching for secure and reliable wireless internet access. The quality of Wi-Fi service will have to conquer many challenges as the major focus shift towards of Internet of Things.
Network slicing is a type of virtual network architecture that allows various networks to be created on top of a mutually shared physical infrastructure. These virtual networks are then personalized to meet the particular needs and demands of devices, applications, services, operators or customers. It uses the same principles as those behind network functions virtualization (NFV) and software defined networking (SDN). The greater flexibility brought out by network slicing will help address the efficiency, cost, and versatility requirements levied by the future.
An inclusive and constantly evolving cloud computing platform, Amazon Web Services (AWS), is another milestone achieved by the retail giant. Web services, popularly termed as cloud computing services, are facilitating millions of users across the globe. The first AWS offerings surfaced in 2006 and offered online services for client-side applications and websites. Amazon Web Service was initially nothing but the company’s backend technology.
Cloud computing will soon be a norm for hosting software applications catering to a variety of use-cases in different verticals. Cloud Computing refers to Internet-based services that provide access to managed IT resources; these resources are managed by experts and are available on-demand on a pay-per-use model. This enables the application developers to focus on the use-case and come up with an MVP (minimum viable product) in a shorter period.
An infrastructure where processing and data storage takes place outside mobile devices can be referred to as a ‘mobile cloud’. By utilizing the computing and storage capabilities of the mobile cloud, computer applications can run on low resource mobile devices.
Network Functions Virtualization (NFV) lets you turn network functions into virtualized functions, thereby allowing you to run them on less-expensive server hardware rather than on high-cost network hardware … read more

This decade started with the wave of big data. Big data technologies have made it possible to manage and process data-volumes and data-velocity of the order that was considered impossible earlier. Big data technologies have been used in … read more
Network Function Virtualization (NFV) is being keenly followed by the telecom industry and proof of concept implementations are already in process. NFV is an engineering approach of building telecom systems (Network Entities or Network Functions) by making effective use of commodity … read more
Data connectivity in mobile terminals has taken asset tracking to a different level. Now, asset tracking is not limited to inventory management, rather we can have online location tracking of moving assets based on their GPS fix. All we need to do is to install a mobile terminal on the asset … read more
As expected, the major groups handling the inner-workings of the internet had announced on Thursday, 3 Feb 2011, that the final unassigned IPv4 address blocks have been handed over to the five regional internet registries (RIR) [ARIN]. This marks the official, albeit symbolic, end of IPv4 and the … read more
Broadband IP is a great leveling ground when it comes to converged services being offered by multiple providers. For example, with the availability of Broadband, companies such as Vonage could offer IP based phone replacement solutions threatening the turf of established phone operators. … read more
