    • A scalable resource allocation scheme for NFV: Balancing utilization and path stretch 

      Woldeyohannes, Yordanos Tibebu; Mohammadkhan, Ali; Ramakrishnan, K. K.; Jiang, Yuming (Chapter, 2018)
      Network Function Virtualization (NFV) implements network middlebox functions in software, enabling them to be more flexible and dynamic. NFV resource allocation methods can exploit the capabilities of virtual- ization to ...

    • ClusPR: Balancing Multiple Objectives at Scale for NFV Resource Allocation 

      Woldeyohannes, Yordanos Tibebu; Mohammadkhan, Ali; Ramakrishnan, K. K.; Jiang, Yuming (Journal article; Peer reviewed, 2018)
      Network function virtualization (NFV) implements network middleboxes in software, enabling them to be more flexible and dynamic. NFV resource allocation methods can exploit the capabilities of virtualization to dynamically ...

    • CoShare: An Efficient Approach for RedundancyAllocation in NFV 

      Woldeyohannes, Yordanos Tibebu; Tola, Besmir; Jiang, Yuming; Ramakrishnan, K. K. (Peer reviewed; Journal article, 2021)
      An appealing feature of Network Function Virtualization (NFV) is that in an NFV-based network, a network function (NF) instance may be placed at any node. On the one hand this offers great flexibility in allocation of ...

    • Efficient Allocation of Resources in NFV-Enabled Networks 

      Woldeyohannes, Yordanos Tibebu (Doctoral theses at NTNU;2020:399, Doctoral thesis, 2020)
      The network traffic and number of devices that are connected within a network are increasing, driven by the increase in network coverage as well as the types of network services provisioned. The provisioning of network ...

    • Joint head selection and airtime allocation for data dissemination in mobile social networks 

      Mao, Zhifei; Jiang, Yuming; Di, Xiaoqiang; Woldeyohannes, Yordanos Tibebu (Peer reviewed; Journal article, 2020)
      By forming a temporary group, users in mobile social networks (MSNs) can disseminate data to others in proximity with short-range communication technologies. However, due to user mobility, airtime available for users in ...

    • Measures for Network Structural Dependency Analysis 

      Woldeyohannes, Yordanos Tibebu; Jiang, Yuming (Journal article; Peer reviewed, 2018)
      A set of new measures for network structural dependency analysis is introduced. These measures are based on geodesic distance, which is the number of links in a shortest path. They capture the structural dependency effect ...

    • Towards Carrier-Grade Service Provisioning in NFV 

      Woldeyohannes, Yordanos Tibebu; Tola, Besmir; Jiang, Yuming (Chapter, 2019)
      Network Function Virtualization (NFV) is an emerging technology that reduces cost and brings flexibility in the provisioning of services. NFV-based networks are expected to be able to provide carrier-grade services, which ...
