Software-Defined Network (SDN) is a promising network paradigm that separates the control
plane and data plane in the network. It has shown great advantages in simplifying network …

Motivated by multiple genome assembly problems and other applications, we study the
following minimum path flow decomposition problem: Given a directed acyclic graph G=(V …

It is a well-established fact that routing metrics cannot be optimized via shortest path
algorithms unless they are both monotone and isotonic. In particular, monotonicity …

For achieving various network optimization and management goals in data centers, some
VMs need to be migrated from the initial servers to the target ones. Live VM migration is an …

Multipath forwarding has been recently proposed to improve utilization in data centers
leveraged by its redundant network design. However, most multipath proposals require …

Software Defined Network (SDN) has been envisioned as the next generation network
infrastructure, which simplify network management by decoupling the control plane and data …

Workload mapping in cloud environment refers to map multiple workloads provided by the
cloud users/tenants to the substrate network provided by the cloud providers, which is a NP …

Sometimes user has the requirement to run a high bandwidth application over a low
bandwidth network. But its implementation is not easy as the traditional network transmits …

The transmission of a traffic flows with a certain bandwidth demand over a single network
path is either not possible or not cost-effective. In these cases, it is veritably periodic usable …
