In the last years, networking scenarios have been evolving, hand-in-hand with new and varied applications with heterogeneous Quality of Service (QoS) requirements. These requirements must be efficiently and effectively delivered. Given its static layered structure and almost complete lack of built-in QoS support, the current TCP/IP-based Internet hinders such an evolution. In contrast, the clean-slate...
With the increasing usage of cloud computing and dependence on a diverse set of distributed applications, users are reliant on consistent outcomes from a shared infrastructure. This drives the need for improved QoS guarantees for heterogeneous communication requirements over shared networks. The Recursive Inter-Network Architecture (RINA) is a fundamental programmable network architecture that provides...
Current multi-tier and over provision Data Centre Network (DCN) architectures with significant cost, complexity, and power consumption are unable to provide adequate throughput and performance according to the increasing traffic growth and IT demands. In response to these identified limitations, this paper proposes a new DCN architecture featuring all-optical switching technologies using both Optical...
Recently, Spectrum Switched Optical Networks (SSON) have been receiving much interest from the research community due to their network performance benefits. Some of these benefits include the possibility of enabling either super channels or sub-wavelength channels, which meet better the granularity of Internet needs. Due to its specific routing and resource assignment characteristics, SSON's primordial...
Applications running inside data centers are enabled through the cooperation of thousands of servers arranged in racks and interconnected together through the data center network. Current DCN architectures based on electronic devices are neither scalable to face the massive growth of DCs, nor flexible enough to efficiently and cost-effectively support highly dynamic application traffic profiles. The...
The virtual circuit characteristic of MPLS and GMPLS architectures has enabled the implement of Traffic Engineering (TE) and Differentiated Services (Diff-Serv) profile to networks. Both schemes are possible by the application of preemption policies and priority of path assignment. With the advent of Path Computation Element (PCE) the routing task can be centralized and properly (re-)designed to accommodate...
