2021 24th Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2021
Among many other key features, the 5G technology introduced the concept of Network Slicing. It supports that different services or even different operators use the same network resources in a dedicated or shared way. On the other hand, QoS for the traffic is mostly provided on the network resources by weighted or strict scheduling.

Service Chaining for Heterogeneous Middleboxes
2020 International Conference on Field-Programmable Technology (ICFPT), 2020In this paper, we describe a new session-level approach for network function virtualization that steers packets through both FPGA- and processor-based middleboxes. We support inter-domain service chaining, dynamic modification of service chains for ongoing sessions, and application of session-level approaches for UDP-based protocols. To demonstrate our

Service failure diagnosis in service function chain
2017 19th Asia-Pacific Network Operations and Management Symposium (APNOMS), 2017Network function virtualization (NFV) is a powerful emerging technique with widespread applicability. It provides Network Functions (NFs) through software virtualization techniques that decouple software and hardware. Some connected network functions constitute a service function chain (SFC).

Dynamic Service Chaining with Dysco
Proceedings of the Conference of the ACM Special Interest Group on Data Communication, 2017Middleboxes are crucial for improving network security and performance, but only if the right traffic goes through the right middleboxes at the right time. Existing traffic-steering techniques rely on a central controller to install fine-grained forwarding rules in network elements---at the expense of a large number of rules, a central point of failure,

Cycle-Service-Level in Guaranteed-Service supply chains
2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO), 2013—The Guaranteed-Service Model (GSM) aims at determining the optimal placement and amount of safety stocks in a guaranteed-service supply chain. In the GSM, safety stocks are used to protect against demand variability up to specified demand bounds. The model does not address what happens when demand exceeds these bounds while in practice, companies ...

On Achieving Trustworthy Service Function Chaining
IEEE Transactions on Network and Service Management, 2021Service Function Chaining (SFC) has recently received considerable attentions from both industry and academia, due to its potential for improving the flexibility of provisioning and composition of Virtualized Network Functions (VNFs) to suit application-specific needs.

Service Level Composition across Multiple Service Chains
2012 IEEE Ninth International Conference on Services Computing, 2012International standards and references about ITSM, like ISO 20.000 and ITIL, deal with the management of service quality, define SLAs (e.g. availability, response time, etc.), and how to manage them from a process perspective. These definitions can be applied both to a service provided by a single provider under a single Service Level Agreement and, in

Dynamic Service Selection at Runtime for Service Supply Chain
IFAC Proceedings Volumes, 2013Abstract Most of the research on service selection treat the quality of service (QoS) as deterministic quantities and only consider the optimization of service supply chain at design time. However, the stochastic nature of services and the dynamic execution of service supply chain are unavoidable.

Oktopus: Service Chaining for Multicast Traffic
2020 IEEE 28th International Conference on Network Protocols (ICNP), 2020Multicast service chaining refers to the orchestration of network services for multicast traffic. Paths of a multicast session that span the source, destinations and required services form a complex structure that we refer to as the multicast distribution graph.
