Inter-domain communication in time-sensitive networks (TSN) has been identified as a requirement for various use cases. The TSN Toolbox provides standards for dynamic stream reservations, which is needed for, e.g., batch size 1 production, but these standards do not support the interaction on the control plane between multiple TSN domains. This paper presents control plane mechanisms for multi-domain time sensitive networks (MDTSNs) integrating an east–westbound protocol in the existing TSN control plane, in order to achieve multi-domain on-demand end-to-end bounded-latency TSN streams. Solutions for issues resulting from MDTSN, particularly the inter-domain forwarding offset, are presented. A proof of concept has been implemented and evaluated in a physical MDTSN test environment in order to prove the viability of the mechanisms developed.

AbstractNetwork slicing will permit offering to vertical customers tailored end-to-end logical networks in an on-demand fashion, on top of a common telecom infrastructure, achieving a Slices-as-a-Service (SlaaS) business model. This is possible due to the progressive introduction of network softwarization techniques, such as programmability and virtualization, into existing operational networks, enabling dynamic and flexible provision of slices. Those vertical customers could require the control not only of the network functions composing the end-to-end service, but also of the connectivity among them, e.g., for influencing the paths for steering traffic among function instances. However, this can be problematic since decisions from one vertical customer can collide with decisions from others. One aspect not yet sufficiently investigated is how to permit vertical customers to jointly control the service functions and the underlay connectivity, in such a way that could operate the allocated slice as if it was actually a dedicated network entirely for them. This paper explores some architectural proposition in this respect illustrated with some potential use cases and it provides an example of the provision of SlaaS for a vertical customer.

Abstract Microrobots have attracted great attentions due to their wide applications in microobjects manipulation and targeted drug delivery. To realize more complex micro/nano cargos manipulation (e.g., encapsulation and release) in biological applications, endowing microrobots with shapes adaptability with the environment is highly desirable. Here, designable shape-morphing microrobots (SMMRs) have been developed by programmatically encoding different expansion rate in a pH-responsive hydrogel. Combined with magnetic propelling, the shape-morphing microcrab (SMMC) is capable of performing targeted microparticle delivery, including gripping, transporting, and releasing through claws morphing. As a proof-of-concept demonstration, the shape-morphing microfish (SMMF) is designed to encapsulate drug (doxorubicin (DOX)) by closing mouth in phosphate buffer saline (PBS, pH~7.4) and release them by opening mouth in slightly acid solution (pH<7), which realize localized Hela cells treatment in an artificial vascular network. These SMMRs with powerful shape morphing capabilities and remote motion controllability provide new platforms for complex microcargos operation and on-demand drug release.

Aiming at the problem that the optical link may be too expensive or even impossible to achieve in a large number of locations in the central part of the backhaul line, the proof-of-concept (PoC) verification of a millimeter-wave integrated heterogeneous network (HetNet) is proposed. HetNet includes a traditional macrocell network and a new small unit that uses a millimeter wave for backhaul line and link access. The concept of a segmentation control plane and user plane was introduced. In the HetNet integrated millimeter wave, the control plane and the user plane were segmented to support the uninterrupted connection and enhance the capacity of the millimeter wave small base station. Millimeter wave communication could be used not only for access links, but also for wireless backhaul links, which will facilitate the installation of small millimeter wave cells. Through conceptual verification (PoC), the feasibility of millimeter-wave integrated HetNet prototype with millimeter wave technology used for return lines and link access is proved.

This chapter presents a ‘Case Study’ based on the distributed market. The requirements of this Grid Business Process are more demanding than any typical business process deployed within a single organization or enterprise. Recently different specifications built on top of Web service standards have originated from the Grid paradigm to address limitations of stateless Web services. These emerging specifications are evaluated in the first part of the chapter to capture requirements of a dynamic business process i.e. Business Process Grid. In second part of the chapter, a case study with different use cases is presented to simulate various scenarios. The abstract discussion and requirements of the case study is followed by the actual implementation. The implementation is meant for the proof-of-concept rather than fully functional application.

Control And Management

As an important support for quantum communication, quantum key distribution (QKD) networks have achieved a relatively mature level of development, and they face higher requirements for multi-user end-to-end networking capabilities. Thus, QKD networks need an effective management plane to control and coordinate with the QKD resources. As a promising technology, software defined networking (SDN) can separate the control and management of QKD networks from the actual forwarding of the quantum keys. This paper systematically introduces QKD networks enabled by SDN, by elaborating on its overall architecture, related interfaces, and protocols. Then, three-use cases are provided as important paradigms with their corresponding schemes and simulation performances.

The network security must be taken into consideration in wireless sensor networks. In our project, we take sensor node data falsification (SNDF) attack using malicious nodes and co-operative detection is used. Fusioncentre collects information from the nodes created in a cluster environment and makes a global decision. The protocol used here is Ad-hoc-on demand distance vector[5] (AODV) and the performance analysis is done using parameters such as throughput and End-to-end delay. The stimulation is done in NS2 using network animator and graphical results are taken.The throughput will be increased compared to the existing system whereas End-to-End delay will be decreased.
