Clos-based network topologies have been deployed in production data center networks to provide multiple path alternatives between the pairs of network hosts. Production data centers operate under varying traffic dynamics and topological asymmetry. Therefore, a good load balancing scheme must adapt to network conditions and dynamics in real-time and intelligently...
Modern datacenters are constructed with multirooted tree topologies and support multiple service queues per switch port. They support a wide variety of applications and services with stringent performance needs and conflicting requirements. To meet these requirements, recent works focus on load balancing or ECN marking approaches. Though existing load-balancing approaches...
Recently, Explicit Congestion Notification (ECN) has been leveraged by most Datacenter Network (DCN) protocols for congestion control to achieve high throughput and low latency. However, the majority of these approaches assume that each switch port has one queue while current industry trends towards having multiple queues per switch port. To...
This paper provides a cross-layer analysis of uplink performance in femtocell networks. It characterizes the uplink physical
interference in femtocell networks and studies its impact on the delay and data loss rate of constant-bit-rate (CBR) traffic, as well
as on the maximum achievable femto-user throughput. Our work derives data-link layer...
This paper presents recent advancements in resource management for large-scale DSA Systems. Although the problem of spectrum and power allocation is well addressed in the literature, the need for more efficient algorithms still persists due to the exponential growth of the number of wireless devices. Thus, developing efficient distributed approaches...
Energy consumption has become a significant concern for cloud service providers due to financial as well as environmental factors. As a result, cloud service providers are seeking innovative ways that allow them to reduce the amount of energy that their data centers consume. They are calling for the development of...
Software-Defined Networking (SDN) is a new networking
paradigm that decouples the forwarding and control planes—
traditionally being coupled with one another—while adopting a
logically centralized architecture aiming to increase network agility
and programability. While many efforts are currently being made
to standardize this emerging paradigm, careful attentions need to
be...
