• Toward dynamic virtualized network services in telecom operator networks

  سند علمی۲۰۱۵Computer NetworksIvano Cerrato, Alex Palesandro, Fulvio Risso, Marc Suñé

  NFV and SDN are nowadays seen as a solid opportunity by telecom operators to reduce costs while at the same time providing new and better services. Recently, the Unify project proposed a multi-layered architecture that, leveraging different levels of abstraction, can orchestrate

• On service-chaining strategies using Virtual Network Functions in operator networks

  سند علمی۲۰۱۸Computer NetworksAbhishek Gupta, M. Farhan Habib, Uttam Mandal, Pulak Chowdhury

  Network functions (e.g., firewalls, load balancers, etc.) have been traditionally provided through proprietary hardware appliances. Often, hardware appliances need to be hardwired back-to-back to form a service chain providing chained network functions. Hardware appliances cannot

• Virtual Network Services For Federated Cloud Computing

  سند علمی۲۰۰۹David Hadas, Sergey Guenender, Benny Rochwerger

  Creating a seemingly infinite cloud computing infrastructure where services can be deployed, extended, and migrated on demand and across different administrative domains, IT platforms and geographies sets new challenges for virtual networking. This work highlights a set of basic

• Dynamic Virtual Network Allocation for OpenFlow Based Cloud Resident Data Center

  سند علمی۲۰۱۳IEICE TransactionsTri Trinh, Hiroshi Esaki, Chaodit Aswakul

  Dynamic virtual network allocation is a promising traffic control model for cloud resident data center which offers virtual data centers for customers from the provider’s substrate cloud. Unfortunately, dynamic virtual network allocation designed in the past was aimed to the Inte

• JASPER: Joint Optimization of Scaling, Placement, and Routing of Virtual Network Services

  سند علمی۲۰۱۷CoRRSevil Dräxler, Holger Karl, Zoltán Ádám Mann

  To adapt to continuously changing workloads in networks, components of the running network services may need to be replicated (scaling the network service) and allocated to physical resources (placement) dynamically, also necessitating dynamic re-routing of flows between service

• Specifying and Analyzing Virtual Network Services Using Queuing Petri Nets

  سند علمی۲۰۱۸Stefan Schneider, Arnab Sharma, Holger Karl, Heike Wehrheim

  For optimal placement and orchestration of network services, it is crucial that their structure and semantics are specified clearly and comprehensively and are available to an orchestrator. Existing specification approaches are either ambiguous or miss important aspects regarding
