Decomposing SLAs for Network Slicing

Modeling quantitative requirements in SLAs with network calculus

When planning Service-Oriented Architectures requirements declared in Service Level Agreements (SLAs) have to be considered. SLAs cover functional as well as quantitative requirements like load levels, services rates and delay times. As external factors can influence distributed systems, SLAs have to include tolerances for quantitative requirements. Early design phases of SOA use analytic model...

Towards 5G Network Slicing over Multiple-Domains

End-to-end Network Slicing for 5G Mobile Networks

The research and development (R&D) and the standardization of the 5th Generation (5G) mobile networking technologies are proceeding at a rapid pace all around the world. In this paper, we introduce the emerging concept of network slicing that is considered one of the most significant technology challenges for 5G mobile networking infrastructure, summarize our preliminary research efforts to ena...

Radio Access Network Resource Slicing for Flexible Service Execution

Network slicing is a key enabler for the serviceoriented 5G vision, that aims to satisfy various per-service requirements. Unlike core network slicing, radio access network (RAN) slicing is still at its infancy, with several works just starting to investigate the challenges and potentials to enable a mutli-tenant, multi-service RAN. One of the major challenges in RAN slicing is to provide diffe...

Virtualization and Slicing of Wireless Mesh Network

Experiments performed on a network provide an exact performance of network algorithms and protocols. While initial research ideas can be evaluated through analysis, simulations, and emulations, implementation and deployment of these ideas on a realistic environment helps in systematically identifying and addressing many practical problems that systems typically encounter. There is no substitute...
