Software defined networking (SDN) and Network function Virtualization (NFV) are the key technologies driving the transformation of the next generation networks. There have been accelerating efforts industry-wide towards swapping traditional networking architectures with SDN/NFV based architectures– to overcome the challenges faced by carriers and enterprises – enormous demand for bandwidth, latency, scalability, reliability and vendor independence etc. Emerging technologies like IoT and MEC need SDN/NFV to deliver an agile and flexible network infrastructure, to handle varying user-demands and diverse network scenarios.
HSC provides engineering services in the following:
Rapid developments in the wireless industry have put enormous pressure on equipment manufacturers’ R&D teams to keep up with changes in specifications, new feature development and maintenance of existing products.

Cellular traffic offload is emerging as an area of great interest for network providers, as they are struggling to keep up with the exponential growth in mobile data traffic which may eventually choke up cellular network capacity. HSC recognized this trend early on and has developed expertise and solutions in various technologies and implementations which allow the cellular networks to offload data.
HSC started its initiative in SON (self-organizing/optimizing networks) while the specifications were still in their early phases. 3GPP has made significant push in LTE standards to make them more self-manageable and to increase level of automation in operation and maintenance of LTE nodes. HSC has been working in the SON space both as an independent research initiative, as well as for our customers.
HSC has extensive experience in small cell design and development across baseband, protocol stack, backhaul and O&M domain. We have worked on development of 3G and LTE small cells in architecture consultancy and product engineering modes.
Network Functions Virtualization (NFV) is an evolved system engineering approach for building complex applications, particularly in the telecommunications and service provider industries, by making effective use of virtualized resources. In the present scenarios, where new applications are difficult to conceptualize and more focus is on consolidation of resources to optimize the cost, NFV helps in reengineering. Check out HSC's multiple offerings in this space.
HSC has an experienced team of network engineers who provide first class product engineering and systems integration services to build, deploy, manage and orchestrate high performance Virtual Network Functions.
This article focusses on leveraging micro-services architecture for upcoming applications, challenging requirements they pose in their provisioning/deployment/management and how latest trends in virtualization and cloud-computing space can help in resolving these requirements.
As the world advances towards the next generation of communication networks, there is a pressing need for new technology solutions, architectures, and standards. This evolution of communication networks is set to facilitate many compelling business and consumer use cases & accelerate huge investment in networks infrastructure, applications, and devices.
Virtual Network Functions are a new trend in the architecting of network services. In VNF terminology, a single network function is decomposed into multiple modules or services, which are then deployed using a combination of virtual machines and cloud deployment, under the control of an orchestration solution such as Openstack, typically deployed over an SDN networking infrastructure. By disintegrating the service into micro-services and then using sophisticated mediation, orchestration and scaling services, the network operator can have optimal allocation of both computing and networking resources.
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.
This document enlists some of the key use cases of SDN in emerging next generation networks and how popular SDN controllers like ONOS, ODL can be used to conceptualize these use cases.
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.
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.
Virtualization and cloud are frequently used interchangeably. However, both of these are different concepts. Virtualization is the act of producing a virtual version of something, which includes but is not restricted to a storage device, virtual computer hardware platform, and operating system or computer network resources. Virtualization improves utilization of resources and enables you to pack more applications onto your infrastructure.
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 infrastructure. There’s little doubt that you’ll see an increase in service agility because of NFV, but to make the most of it, you need to have a realistic picture of which services are easy to migrate and which ones take more time.
5G wireless networks can support over 100 billion device connections and are capable of extremely low latency. The advent of 5G technology signifies the wave of ‘highly inter connected’ digital society. Presently accessing the internet with mobile devices is becoming a common scenario around the world. Consumers are now able to conduct operations across physical and geographical boundaries, something that inhibited growth in the past decades.
The case for mmWave in 5G networks is rather strong (Rappaport, Sun, et al. 2013). Given the continuous demand for spectrum and the recent progresses in mmIC fabrication technology, we can reasonably expect to see mmWave migrate from the existing point to point backhaul links to a more dynamic role; fronthaul (the link between the base-band unit (BBU) and the remote-radio heads (RRH) of the newly decoupled cloud RAN (Mugen Peng 2015)) and eventually the access network.
It has long been the trend that modern wireless networks have been getting denser as time goes on; where, by the term dense, we refer to the gap between network nodes (the ‘points of presence’ of the network) and the average area intended to be covered by the single node. Till now, this has primarily been driven by the increasing demands for bandwidth for users, exponentially increasing numbers of users and the deployment of networks in higher and higher frequencies. The last point is important because scattering increases (and hence, the effective radius decreases) as the network node uses a higher frequency.
Majority of the end-user demand today is from the mobile devices using WiFi for connecting to the network. SDN provides scalable network control functions, flexibly adjusts the resource allocations and handles the changing traffic patterns of the wireless networks.
The 5th generation cellular networks have set an explicit target to improve the performance of cell-edge users. This is widely acknowledged in the industry as being a challenge; multiple studies have modelled cell-edge channels and UE performance in representative modern cellular systems. It is known that there are multiple factors involved; these include higher path loss, non-uniform power distribution by the primary network node, interference from neighbouring nodes, lack of diversity in paths, etc.
