Software-Defined Networking (SDN) refers to a new approach for network programmability, that is, the capacity to initialize, control, change, and manage network behavior dynamically via open interfaces. SDN emphasizes the role of software in running networks through the introduction of an abstraction for the data forwarding plane and, by doing so, separates it from the control plane. This separ...

Data center networks (DCNs) rely heavily on the use of group communications for various tasks. For example, data center management utilities (e.g., software update/upgrade, log management, resource monitoring, scaling up or down of resources, access control etc.), collaborative applications (e.g., social media, project management tools, version control systems, etc.), multimedia applications an...

SDN and NFV are modern techniques to implement networking infrastructures and can be used also to implement other advanced functionalities, such as the protection architecture designed by the SECURED project. This paper discusses a couple of techniques – trustworthy network infrastructure monitoring and remote attestation of virtual machines – useful towards a trusted and secure usage of SDN an...

Software Defined Networking (SDN) is an emerging architecture, which allows networks to be centralized and programmable, aiding researchers in implementing complex network algorithms and policies. While SDN is widely used in LANs, it has also been deployed in WAN environments [2]. Like Tor, Decoy Routing [3] aids users to circumvent censorship on the Internet. While Tor uses onion routing, Deco...

the proliferation of information and communications technology (ict) along with the incremental growth in the use of cloud services, enterprise network and data center technologies in recent years, have caused unprecedented expansion of computer networks. however, the existing network architecture was not well designed to meet the requirements of today's needs. one of the most important pr...

High-level SDN languages raise the level of abstraction in SDN programming from managing individual switches to programming network-wide policies. In this talk, we present Cocoon (for Correct by Construction Networking), an SDN programming language designed around the idea of iterative refinement. The network programmer starts with a high-level description of the desired network behavior, focus...

Software-defined networking (SDN) seeks to simplify and enhance network management by decoupling the management logic from its implementation. Our overarching vision is to integrate advanced data plane functions or middleboxes (e.g., firewalls, NATs, proxies, intrusion detection and prevention systems, and application-level gateways) into the SDN fold. This integration, however, is challenging ...

ions provide new tools to enable the richer networking functionalities demanded by recent industry trends including dynamic virtual server workloads, multi-tenant cloud computing, and warehouse-scale data centers. Existing standards and abstractions have proven inadequate for delivering this functionality Bat scale[; for example, 12-bit virtual local area network (VLAN) identifiers [2] allow fo...
