The next generation monitoring solutions should evolve as fast as the applications they will support both in terms of functionality (e.g. new protocols, monitoring function, etc.) as well as in terms of scale and performance. We believe the field of network monitoring is yet to experience the same revolutionary transformation as software-defined networking (SDN) and network function visualization...
We are witnessing a considerable amount of research work related to data center and cloud infrastructures but evaluations are often limited to small-scale scenarios as very few researchers have access to a real infrastructure to confront their ideas to reality. In this demo we will reveal our experiment automation tool, DiG (Data centers in the Grid), which explicitly allocates physical resources...
This demonstration paper details the cloud based service enablement platform developed in the EU FP7 Mobile Cloud Networking project. This demonstration shows on a mobile core network can be instantiated on demand on top of a standard cloud infrastructure.
Virtualization of network elements and the transition from embedded systems requires an extension of the existing paradigm of software lifecycle development and management to what traditionally has been done for each embedded system. In this paper IBM will cover the end-to-end design of such systems such that they can deliver deterministic, repeatable services in both a hybrid and fully virtualized...
The EU funded FP7 project T-NOVA, with the specific goal of accelerating the evolution of NFV, proposes an open architecture to provide Virtual Network Functions as a Service (VNFaaS), together with a dynamic, and flexible platform for the management of Network Services (NSs) composed by those Virtual Network Functions (VNFs). The proposed architecture allows operators to deploy distinct virtualized...
With the soar of Software Defined Networking planning a network service becomes harder of a task than ever before. Selecting traditional network elements that provide the best value for money given the performance requirements and the allocated budget is not the only option today: one might also take the software solution on generic hardware alternative. The problem is that the set of available solutions...
In this demo, we provide a Mininet-based Software-Defined Network (SDN) simulation environment that improves the total flow throughput and scalability of the overall network. Mininet is a suitable and manageable tool to implement the proposed SDN based flow admission control module in order to configure the entire topology since it has already built in Open-Flow switches and virtual controllers. This...
In this demo, we implement a realtime testbed for Software Defined Wireless Networks (SDWN) by using Raspberry Pi as OpenFlow (OF) Switches. The implemented testbed provides practical development and testing environment for SDWNs. Moreover, we use OpenDayLight to observe the flows and events in the network. With OpenDayLight integration, we easily provide detailed analysis results for any testing...
SDN and NFV are two paradigms that introduce unseen flexibility in telecom networks. Where previously telecom services were provided by dedicated hardware and associated (vendor-specific) protocols, SDN enables to control telecom networks through specialized software running on controllers. NFV enables highly optimized packet-processing network functions to run on generic/multi-purpose hardware such...
Service Providers are relying on Network Functions Virtualization (NFV), an ETSI industry specification, to achieve on-demand delivery of network services by avoiding long hardware deployment cycles. ETSI NFV supports dynamic workloads by scaling out virtual network functions (VNF) using industry standard high volume servers, switches and storage infrastructure. Further, NFV enables the IT administrator...
Today the notion of Service Function Chaining (SFC) returns to the focus of technological development in the area of network management and design. Researchers focus on exploiting the advantages of Network Function Virtualization (NFV) and Software Defined Networking (SDN) to bring SFC to a brand new level of fast and flexible, modern end-to-end service orchestration. The core of SFC architecture...
With the recent advances in SDN-based technologies, there is a great interest from different communities to exploit SDN for their domain needs. One of such domains is Smart Grid where the underlying network is going through a massive upgrade to enable not only faster and reliable communications but also convenient control. To this end, SDN can be a viable option to provide resilience in Smart Grid...
We present Flowsim, a new web-based OpenFlow data plane simulator. Flowsim enables users to configure their own OpenFlow switches, issue OpenFlow messages, inject custom packet sequences into the data plane, and observe the resulting behavior. During a simulation, the life cycle of an injected packet is analyzed as it traverses the OpenFlow data plane. The user is presented with visualizations that...
Software defined radios (SDR) have revolutionized communications by enabling flexible implementation and deployment of physical layer and medium access control protocols through software, without the need for specialized hardware. Although SDRs have been around for many years now, there is still tremendous interest to make them work in scenarios that were not previously thought possible. One such...
The emphasis today in Network Functions Virtualization (NFV) is on moving existing monolithic telecommunications services like the IP Multimedia Subsystem (IMS) as a unit to a virtualized infrastructure platform. Yet the next step will involve breaking down the monolithic services into smaller, more modular units called Virtualized Network Functions (VNFs) that can be quickly combined into cloud-based...
