Hi. In next couple of sections, we'll be covering Edge Computing for communications service providers beyond basic definitions. This will include discussion about locations from which hardware and software platforms will be providing appropriate use cases in business models, delivering these type of Edge services. So Edge Computing is the model of placement of compute, storage, and networking functionalities, deeper into the carrier network to be closer to the end customers or devices communicating. And this is where we get too much better latencies and higher bandwidths. Also, based on that, we can go and deliver better services capabilities, optimize the TCO, and comply with various regulatory requirements, including data locality. So this way, the Edge allows placing these type of computes in the network, so that the devices themselves are closer to other devices and to the other networks related to their services, without crossing all the care and network, all the hierarchies going up and down, just to reach the next device, maybe connect it on to the same aggregation point or something like that. So this is the foundation and the requirement to implement what was previously introduced as telco cloud, so that we get end to end metric transformed in a way that we are allowing this type of compute platforms in different hierarchies inside the network, so this then takes advantage of what was being done for the cloud backends for the core network, Edge in particular here, then Access, and also in some cases on premise for the let's say enterprise ID. And this type of transformation, starting from virtualization, software defining everything, allows the automation, making it cloud ready, for this distributed telco cloud concept, allows us to prepare for incremental services compared to what it does today. But then eventually when there is 5G standards agreed, this allows for incremental use cases, incremental revenues, very differentiating for the [INAUDIBLE].. A little bit-- another type of representation on where exactly is this Edge. Saw this was the idea of introducing virtualization and cloud principles into the regional data centers, central offices, aggregation points, placing these type of compute platforms in the distributed locations. Critical is that all of that is, if possible, gets exposed as one platform, so that [? virtual ?] placement then correctly chooses where to put appropriate instances. When we talk about latencies, here is a representation that is based on conservative calculations and goes and covers different network hierarchies. So the vacant clouds where over-the-top providers can provide their services is hundred-plus milliseconds. And then depending on what is the latency requirement for appropriate use cases, we will have to add the appropriate locations in the network, define those platforms, and run it from there. Where exactly these locations will be depends on number of questions to be answered. It starts simply with what is the geographical coverage that needs to be taken into account, what is the population distribution in this geography, and what is the situation the transport network, how well are these locations ready to receive IT equipments regarding power and heating situation there, also security requirements in those locations. So it's a number of things to be considered inside this location type of category of the definitions. And also in some of the regulatory systems in different countries, it will be required that data stays within given boundaries of geography, also dealing with big enterprises, they will have their own security departments, having their own requirements, so all these type of things can be taken into consideration, and in this way decides what are the right locations to run these types of services.
