Virtualizing the Network Services: Network Function Virtualization

2017
Network function virtualization (NFV) is rapidly emerging as the de facto approach operators will use to deploy their networks. NFV leverages on cloud computing principles to change the way NFs like gateways and middleboxes are offered. As opposed to today’s tightly coupling between the NF software and dedicated hardware, NFV concept requires the ...

SVNE: Survivable Virtual Network Embedding Algorithms for Network Virtualization

IEEE Transactions on Network and Service Management, 2013
Network virtualization can offer more flexibility and better manageability for the future Internet by allowing multiple heterogeneous virtual networks (VN) to coexist on a shared infrastructure provider (InP) network. A major challenge in this respect is the VN embedding problem that deals with the efficient mapping of virtual resources on InP network ...

Network Virtualization and Survivability of 5G Networks

Journal of Network and Systems Management, 2020
5G networks are slated to provide a wide range of services. A critical need in service delivery in 5G networks is its resilience. In this work, we present a 5G network architecture with network virtualization in a multiple provider setting for network resilience that uses a self-organizing ad hoc network among the gNBs (macrosites).

Virtual private social networks

Proceedings of the first ACM conference on Data and application security and privacy, 2011
Social Networking Sites (SNSs) are having a significant impact on the social life of many people - even beyond the millions of people that use them directly. These websites usually allow users to present a profile of themselves through a long list of very detailed information. However, even when such SNSs have advanced privacy policies, users are often

Resilient Virtual Network Service Provision in Network Virtualization Environments

2010 IEEE 16th International Conference on Parallel and Distributed Systems, 2010
Network Virtualization has recently emerged to provide scalable, customized and on-demand virtual network services over a shared substrate network. How to provide VN services with resiliency guarantees against network failures has become a critical issue, meanwhile the service resource usages should be minimized under the strict constraints such as ...

VIRTUAL OPERATIONS ON VIRTUAL NETWORKS: THE PRIORITY UNION

International Journal of Foundations of Computer Science, 2003
Finite state networks can represent dictionaries and lexical relations. Traditional finite-state operations like composition can produce huge networks with prohibitive computation space and time. For a subset of finite state operations, these drawbacks can be avoided by using virtual networks, which rely on structures that are partially built on ...

Virtual Network Embedding for Evolving Networks

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
Network virtualization has been proposed as a powerful vehicle for running multiple customized networks on a shared infrastructure. Virtual network embedding is a critical step for network virtualization that deals with efficient mapping of virtual nodes and virtual links onto the substrate network resources.

Network virtualization over WDM networks

2011 Fifth IEEE International Conference on Advanced Telecommunication Systems and Networks (ANTS), 2011
Network virtualization can eradicate the ossification of the Internet and stimulate innovation of new architectures and applications. Optical networks are ideal substrates for provisioning high-bandwidth virtual-network services. We investigate the problem of network virtualization over WDM networks by formulating a mixed integer linear program (MILP).
