Where is the EDGE?


Where is the edge?




The most budging term in telecom or IT industry today is “EDGE”. In fact there are two notions on the fore one is “edge computing” and other is “fog computing”, both are about bringing the cloud near the point of action. Essentially it’s a cloud computing, a freak of virtualization at front of access.
The need of “edge computing” or “fog computing” has been attributed to “real time” or “low latency” approaches, i.e. process the data at the point or near the point where it is being generated and produce the result for real time action.

Whereas Fog is much on the point of data generation, the edge computing is a centralized or aggregated stuff, at the nearest possible point of access. Therefore fog is much about a flat distributed system but edge is little different through the notion of “edge”.
I don’t want to jump into hardcore technicality with these stuffs, as there would be specifics but essentially it about virtualization at different points in end to end construct. My idea is finding the edge.

“Edge”, as per vendors, is something about hierarchical distribution of certain functionalities in E2E construct. “Edge” is something creates a moat for innovation. I don’t differ with vendors but I feel that edge disrupt the very nature of cloud services too, it’s about providing cloud services with specific needs, different KPIs and SLAs, rather more customized. I am here referring to public cloud as my thought and intention of putting my idea is around that’s only.

So “edge” disrupts the cloud in sense of not only providing a back office or central office work but distribute the work at different level, in terms of SLA and KPIs. Think about the OTT services, the players started them with much turbulence but not only settled but dominated. Edge is in that sense the gate through cloud for many of service creations for small players.

So, don't just confine to architectural adherence from the vendors for creating the edge, there are many possibilities to find your own edge and provide the service.

5G appraoch, where rubber touches the road -Cloud-native approach necessary to deal with complexity of 5G


5G will eventually require a fully virtualized, software-controlled network in order to automate the complexity of network management and service delivery. Although we’re not there yet, test and proofs-of-concept like Deutsche Telekom and Hewlett Packard Enterprise’s (HPE) work to deploy virtual network functions (VNFs) in a cloud-native shared data environment (SDE) is indicative of the progress toward zero-touch networks.

5G will encompass a huge variety of types of traffic, meaning networks need to be architected for flexibility. The three primary 5G use cases are enhanced mobile broadband, massive machine-type communications and ultra reliable low latency communications. Running the gamut from high-bandwidth activities like virtual reality to low-intensity, intermittent communications from connected sensors.

Sven Langer, DT’s senior core network architect, said the proof-of-concept “allowed a rapid and smooth integration with 3rd-party VNFs” and showed a response time around 1 millisecond,” which “provide[s]an excellent basis for cloud-native network functions to externally store all data, especially dynamic context data that allows seamless failovers and improves the customer experience.

HPE’s Dave Sliter highlight the challenges service providers will face with the move to 5G and the new types of services it enables. “Adoption of 5G technology,” he said, “introduces major operational and financial challenges. HPE Shared Data Environment is an essential enabler for this transformation and reduces these risks.”

Is 5G really so hard to break?


5G is not a nut at all like previous Gs. 5G is a re-imagination, paradigm shifts and new vision to accommodate certain advancements on radio and core network technologies, like massive MIMO, SDN/NFV, VNF/Cloud and MEC. 5G is also about upcoming use cases and capability & flexibility provided for them like IOT, Network Slicing or Application defined networking.

By and large it’s an end-to-end overhauling with new instruments to existing networks, which may be of concern for many reason, that need a transformational approach. As VNF and Cloud are most obvious tools to take up the necessary load of new functionality, MEC at the RAN level will be pivotal to discriminate the service logics and catalyze the application specific requirements fulfillment.

The transformation is going to shape-in with the shift in architectural paradigms to more hybrid or heterogeneous approaches and also leveraging the virtualization to accommodate variety of applications and use cases like for massive IOT, public safety, HD  video, mission critical i.e. latency sensitive applications.

Mobile edge computing abbreviated as MEC is about the cloud at edge or may be related to new term called as fog computing which is about putting many of RAN specific functionalities on virtual systems which are adaptive to load and computational requirements. MEC will help to provide right orchestration for VNF kind of architecture need for End to End networking, in term of network operation and performance optimization. MEC is best for the uses cases like for content management networks, latency sensitive applications, massive access management etc.

Virtualization is the kingpin in whole 5G conception as the required flexibility of the systems and network can be provided through it and that help to accommodate the application specific configuration with the term that provide end to end re-construction i.e. it is all about network slicing. Network slicing can also be envisaged as application defined networking that is about ad-hoc re-deployment or re-configuring network in line to the specific application requirements.  As per the 5G specification, this re-deployment time is not in days but in minutes and saying precisely it is 90 minutes only.

Thought to write on 5G again, Allusive or Ellusive?



Thought to write on 5G again, as 5G is still elusive in talk and discussion. 5G is a re-imagination, paradigm shifts and new vision to accommodate certain advancements on radio and core network technologies, like massive MIMO, SDN/NFV, VNF/Cloud and MEC. 5G is also about upcoming use cases and capability & flexibility provided for them like IOT, Network Slicing or Application defined networking.

Is WiFi, 5G?


Many hardcore WiFi evangelist seems to be in cribbing moods while associating WiFi with 5G. Or may be they want to hijack the buzz around 5G for wifi in this way, as WiFi has taken its own stride silently.  WiFi is not 5G, damn clear is this fact, more than that only 5G NR is not 5G. WiFi is altogether different ecosystem, standards development etc.
WiFi has been always relevant and deeply rooted in terms of internet access, also has got significant improvements in standards coping with time, 802.11 n, ac , ax. 5G emerged as utopian kind mobile technology, providing things what the different application want, with necessary capacity and efficiency. Therefore 5G comprises all the advancement in technological space, in computing and communication, like MIMO, Cloud, MEC, SDN, VNF etc. WiFi is one candidate there but a major one (complimentary) with advancement of 802.11ax, to achieve 5G objectives.

Infact we must understand that first standards of 5G through 3GPP release 15 was on 'Non Stand Alone', so called NSA mode. That's about taking 5G NR as associated radio in LTE control network. In true sense on LTE network with a data pipe of NR, Same could be done with any other radio, whether it be WiFi.

WiFi is much mature than NR, which is there taken for FWS only, WiFi has been there since ages as a synonyms of internet connectivity. So where comes a data pipe requirement WiFi is sufficient for multiple or many applications.

Also 5G is about use cases, a technology that will cater almost all the industry for connectivity point of view so akin to accommodate almost all the relevant radio technologies of caliber, we all are aware of some thing called network slicing, WiFi lies on prominent place there.

WiFi essentially a complimentary technology, in light of 5G, and to utter surprise it will be more prominent in 'Stand Alone", so called SA mode of 5G, where LTE will be out and it will be pure 5G network with SOA architectured 5G Core.
