Emerging Networks Laboratory Research Themes


Adaptive Networks

Future communication environments will be composed of large-scale, distributed, and integrated heterogeneous systems that must be adaptive, scalable and robust in order to cope with increased complexities. The Adaptive Network research investigates bio-inspired processes that can be applied to Future Networks, ranging from adaptive resource and route management, to support of IPTV networks.

Policy-based Network Management

As communications networks grow in size, to cope with increasing demand for services, so to does their complexity. Current network management techniques are primarily human centric and based on SNMP monitoring coupled with large volumes of reported statistics. Subsequently, the cost of managing such large-scale networks increases, as the network complexity increases.  Policy-based Network Management (PBNM) is a technique that seeks to break the trend of escalating costs, by separating the rules defining how the network should operate from the complexity of monitoring and configuring a large and heterogeneous network. This research topic investigates effective ways to represent, process and evaluate the rules of a PBNM system, termed “policies”. Read more …

Resource Allocation Techniques

There is an ever increasing need to manage communication and computational resources in a more dynamic, cost effective and energy efficient way. With the widespread uptake of cloud computing and flexible concepts as Platform as a Service (PaaS), Software as a Service (SaaS and Infrastructure as a Service IaaS), there are increased demands on providers to meet the dynamic resource requirements of their customers. This research topic focuses on a broad range of resource allocation strategies including Virtual Machine placement in clouds, resource allocation in data centers and server selection for IPTV networks.

Traffic Measurement and Analysis

As new applications emerge, there is a need to understand their impact on the network and resource requirements to ensure end users experience is satisfactory. This research theme focuses on analysis of both application traffic and network capabilities from a Quality of Service perspective. The theme also investigates the classification of application traffic and identifying a relationship between network level metrics and perceived Quality of Experience by the end user. Read more …

Molecular and Nano Communications

The ability to create communication networks of nanoscale in biological environments has the potential of opening up new opportunities, in particular in healthcare. This research theme is investigating mechanisms of developing synthetic protocols in biological cells, which can be used as a transmitting platform to support molecular communications. Read more …

Scalable Monitoring Techniques

IPTV is an important source of revenue for operators, but this service places huge demands on the network infrastructure. Monitoring and control of these heterogeneous networks is further complicated by the complexity of quality of experience measurement for video. In such a system new approaches to quality assurance and in particular collecting relevant metrics are vital. This work describes a novel architecture for managed quality of experience in IPTV networks. It also explores scalable metric collection techniques using 1) traditional RTP and 2) OpenFlow.
