    • Enhancing the performance of post-failure restoration schemes in multi-tenant networks 

      Ghaleb, Abdulaziz M.; Khalifa, Tarek; Shaban, Khaled Bashir ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      Failure in the physical network can cause a temporal or permanent unavailability of some resources, which can lead to a quality of service (QoS) degradation and loss of revenue. While much work has been dedicated to the ...

    • Surviving link failures in multicast VN embedded applications 

      Ghaleb, Abdulaziz M.; Khalifa, Tarek; Ayoubi, Sara; Shaban, Khaled Bashir ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      Virtual network embedding (VNE) is defined as the allocation of network resources to multiple virtual networks (VNs) and is recognized to be a challenging task to perform efficiently. Virtual network survivability is a new ...

    • Surviving Multiple Failures in Multicast Virtual Networks With Virtual Machines Migration 

      Ghaleb, Abdulaziz M.; Khalifa, Tarek; Ayoubi, Sara; Shaban, Khaled Bashir; Assi, Chadi ( IEEE , 2016 , Article)
      This paper deals with the multiple link/node substrate failures that impact a multicast virtual network (MVN) in which link recovery is not feasible and node migration is mandatory. A novel restoration approach is introduced ...
