No existing QoS-based solution can offer anything like this. For example, DiffServ, which is the most widely deployed QoS solution, can discriminate VoIP traffic from other types of traffic such as HD video and web browsing. However, DiffServ cannot discriminate and differentially treat the same type of traffic (e.g. VoIP traffic) coming from different tenants.<\/p>\n<p>Also, DiffServ does not have the ability to perform traffic isolation at all. For example, IoT traffic from a health monitoring network (e.g. connecting hospitals and outpatients) typically have strict privacy and security requirements including where the data can be stored and who can access it. This cannot be accomplished by DiffServ as it does not have any features dealing with the compute and storage aspects of the network. All these identified shortfalls of DiffServ will be handled by the features being developed for network slicing.<\/p>\n<h2><strong>In summary<\/strong><\/h2>\n<p>Network slicing is very different from QoS because it will enable end-to-end virtual networks encompassing compute, storage and networking functions. Existing QoS approaches are all point solutions which offer a subset of functionality at best when compared to network slicing. Network slicing is generating a lot of excitement in 5G discussions mainly because it will open many new business opportunities. Network slicing is part of the general trend to make network services more virtual and thus benefit from the lower costs and increased innovation that the IT industry reaped with the move to the cloud and Everything-as-a-Service. It is not likely that network slicing will require revolutionary new technical standards. Instead, the technical changes needed will be applied across a myriad of technologies and standards all focused in the key areas of improved network intelligence, system integration, OAM and traffic engineering.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Network Slicing is a 5G-enabled technology that allows the creation of an E2E Network instance across the Mobile Network Domains (Access, Transport, &amp; Core).
