Teachers should lead a discussion considering the following ideas. Cloudstreet is perhaps one of the best known Australian novels and it is often considered not only a modern Australian classic, but a favourite of Australian readers. It is often ranking first in many public polls of the best Australian novels.
And if the machines could talk which they dothey might echo the sentiment. Our devices will not only seem at once much smarter, but in the context of Application-Aware Networks, will provide us complete command of a fluid interplay of experiences that will come to define the digital lifestyle.
This is a good starting point for a discussion of network slicing and its most important mission with the inauguration of hybrid 4G and 5G networks; User Experience.
While much of the discussion on network slicing has revolved around the frameworks for its delivery, and the use cases that they will enable, there has been relatively little examination of the user journey. This is important for several reasons; while a continued refocus on the user is the very heart of any business proposition, it is especially critical in the mobile industry, which touches nearly every aspect of our lives and must re-invent itself around that reality.
Certainly, this idea lies in stark contrast to the connectivity-focused mantras of previous telecom generations. Instead, we look to deliver a truly open, democratized network that takes into consideration each of its constituents, whether man or machine.
But we begin our examination by looking at the many problems network slicing solves, and the unique opportunities it will create. We will follow with a brief look at the history of the model, in its many flavors, approaches and applications along the path to 5G. On the positive side, and in the context of network slicing, there will enough capacity and latency-defined use cases to create an entirely new mobile network with quality of experience and reliability at its core.
In this context, we see the need to not just to move beyond best effort, but to expose it within a mobile services constitution that defines capabilities and realistically sets user expectations.
But there are some challenges. The first problem stems from the fact that by its very nature, cellular capacity is a limited resource and as such behaviorally inconstant. While with the anticipated arrival of radio network enhancements like millimeter wave and small cell technology, cell capacity is expected to go up dramatically, it will not change this essential fact.
The second issue represents both a technical barrier and its corollary as an end user experience. The radio is not the key topic. There is a lot of noise about the radio but we need to make noise about the whole architecture — for me, much more relevant is the issue of network slicing.
The third big challenge relates to the problem of creating and deploying new services. While this is being addressed with the adoption of Software Defined Networks SDN and Network Function Virtualization NFVin a standard 4G services environment, all main infrastructure components including access, transport, management and storage are centralized and tethered to a single physical network.
In this scenario, a new mobile service definition, creation, management and delivery is all but a non-starter. Virtualized Opportunities In the new, virtualized network, however, we see a clear and cost-effective path to a world of new services that directly address users anytime, anywhere with predictably reliable services.
SDN and NFV not only move the operating environment from a physical, monolithic network, to one that effectively segregates operational planes, spawning limitless interoperable, re-usable or retireable virtual network clusters.
These are the building blocks of network slicing, and this critical sea change in the macro stack is an absolute requirement for the new business models and user experiences promised in 5G.
And yet, even before network slicing comes to your town, these elements will have a direct impact on the bottom line. In this re-formulation, setting up your own network and launching new mobile services can be done in minutes instead of months.
By separating the service layer from connectivity and infrastructure a completely new operating environment is born in which the seeds of highly structured virtual architectures will grow.
Not only will these networks and network clusters remove the need for a variety of dedicated electronics in homes and businesses and the network itself, they may well eliminate the need for costly deployments, upgrades and overlays while eliminating costly truck rolls into the future.
User-Defined Networks Writ large, the evolution from the current paradigm to the concept of an Application-Aware Network envisioned for 5G, demands not just a virtualization of core technologies, but a complete re-thinking — a complete inversion — of how a telecom network is conceived.
In this way, the network becomes an environment for the dynamic support of quality-of-experience designed around user demand. So while their experience of slices will be a fluid part of their day-to-day mobile lifestyle, in order for the value of next-generation service orchestration to be properly conveyed, consumers must play a direct and commanding role in its use.
This is fundamental to the transition to a user-centric, user-defined, user-driven relationship with the network provider, and our primary theme of the User-Defined Network. While one might see traffic classes as akin to the grades of gas available at the pump, this is precisely the wrong way to sell services.
Rather, the evolved approach seeks to position mobile performance as a key indicator of the digital lifestyle. That is to say, our role in creating a truly user-defined network is dependent not on merely delivering the connectivity to make that possible, but to involve the buyer in the decision.
We will look at these facets of the opportunity in closer detail later in the paper as we discuss use r case experiences in greater detail.
First, however, we will take a look at the roots of network slicing to provide some historical and technological context.
Presented in purely theoretical terms just three years ago by Ericsson, its first actual commercial deployment was delivered by a startup incubated by their archrival, Nokia.
Imagine the freedom of a mobile crew covering, say, a sailing race or a breaking news story, and limited only to those areas where LTE service is available. While this use case represents the very tip of the iceberg when it comes to the near limitless service experiences and revenue opportunities of network slicing, it provides a good entry point for understanding this essential new telecom model.
This simply relates to whether or not the slices are pre-deployed, or created and delivered in a dynamic, real-time context based on human or machine interaction; the third becomes very technical very quickly but describes the specific locations within the network where the slices may be deployed that include the Core Network CNthe Radio Access Network RAN or at the Resource Level.
To continue unpacking the concept, we will in the next section provide a basic description of the difference between vertical and horizontal slicing and what happens when the latter is deployed as a dynamic, real-time automated system.Jun 23, · Access to either the film or stage production of Cloudstreet would provide an interesting textual comparison.
Both offer many similarities to the novel, though there are critical points of departure. Both offer many similarities to the novel, though there are critical points of departure/5(3). Cloudstreet.
At the end of , students at Tranby eagerly auditioned for the school production of 'Cloudstreet', a vast and intriguing story of Australia written by Tim Winton and adapted by Nick Enright and Justin Monjo. This play is an emotional and heart-warming story of two families brought together by fate and chance.
The Glass Menagerie is a memory play by Tennessee Williams that premiered in and catapulted Williams from obscurity to fame. The play has strong autobiographical elements, featuring characters based on its author, his histrionic mother, and his mentally fragile sister Laura.
In writing the play, Williams drew on an earlier short story, as well . America's Oldest Surviving Feature Film is the production of Richard III starring Frederick Warde. Since then stage performances have been filmed many times.
Looking for Richard is documentary and a dramatic transformation of parts of Shakespeare’s Richard III into film – a familiar medium. NETFLIX Streaming: Period Dramas.
