Network virtualization arises as a potential solution for addressing the current IP limitations through a non-disruptive route, by letting multiple networks, running different protocols, to coexist and share the same infrastructure in an independent way. The purpose of this paper is to make this coexistence of networks a reality through the real support of multiple virtual networks. Therefore, ...

InKeV is a network virtualization platform based on eBPF, an in-kernel execution engine recently upstreamed into linux kernel. InKeV’s key contribution is that it enables in-kernel programmability and configuration of virtualized network functions, allowing to create a distributed virtual network across all edges hosting tenant workloads. Despite high performance demands of production environme...

Network virtualization has become a common research topic that many researchers consider a basis for defining a new generation network architectures. In this paper, we attempt to clarify the concept of network virtualization with its brief history, to introduce the benefit of network virtualization for the future network, to posit our strong belief in that the future network should adopt a form...

Mobility of the subscriber is an important attribute to the success of a telecommunication network. With the advent of 5G networking which achieves high throughput rates by using heterogeneous nodes and frequent handovers, existing authentication and handover techniques should be revisited to securely and reliably perform handovers for LTE LTE. By virtualizing the nodes through Network Function...

Today’s networks are overly complex, partly due to an increasing variety of proprietary, fixed-function appliances that are unable to deliver the agility and economics needed to address constantly changing market requirements. This is because network elements have traditionally been optimized for high packet throughput at the expense of flexibility, thus hampering the development and deployment...

The virtualization of Radio Access Networks (RANs) has been proposed as one of the important use cases of Network Function Virtualization (NFV). In VRAN!s (VRAN!s), some functions from a Base Station (BS), such as those which make up the Base Band Unit (BBU), may be implemented in a shared infrastructure located at either a data center or distributed in network nodes. For the latter option, one...
