Title: The Future of Media Streaming Systems: Transferring Video Using BPP

 

Abstract: Big Packet Protocol (BPP) is a recent protocol which is designed to transfer packets for future networking applications, and aims to overcome obstacles within current networks for high precision services. One of the most important advantages of BPP is that it allows changes to packets during transmission. The strategy of BPP is to reduce the packet size by eliminating specific chunks, which cuts out segments from the transferred video, rather than dropping or retransmitting packets. This provides an interesting mechanism to enhance the performance of video streaming applications, by obtaining continuous delivery and minimum guaranteed quality at the receiver. In order to make video transmission over BPP effective, we need to select a video codec that can do multiple encodings for the same region, such as scalable video coding (SVC). To support such functionality, we have augmented the BPP packet structure in order to transfer video data. This paper describes the use of BPP for carrying video from servers to clients, and defines the packet structure for this purpose, plus the extensions needed to support SVC encoded video. To evaluate the proposed approach, we use SDN to facilitate BPP operations, with results showing a successful implementation of a system using these combined techniques.

Title:Computing Power Network: An Interworking Architecture of Computing and Network Based on IP Extension

 

Abstract:The introduction of edge computing has brought new changes in network traffic model. From the perspective of users, resources in different locations are not equal. The distance between users and resources (different latency), network conditions, as well as charging and many other factors are needed to be considered for choosing the best resource. Therefore, computing power network (CPN) has emerged. It is a new type of network that realizes the best resource allocation, by distributing computing, storage, algorithm and other resource information of service nodes through network control plane (such as centralized controller, distributed routing protocol, etc.). It combines network context and user requirements to provide the optimal distribution, association, transaction and scheduling of computation storage and network resources.

Title: High-precision accounting for high-precision network services

 

Abstract: The networking landscape is expected to undergo profound changes over the coming years, with new applications emerging that depend on the ability of networks to provide high-precision services with stringent service-level guarantees. To enable and incentivize network providers to deploy and deliver such services will also require advances in the way such services can be accounted for. At its core, this will require support for high-precision metering that allows to generate custom accounting records that can be custom tailored towards specific service offerings and service level agreements. This paper presents a framework to enable such metering.

Title: A Proof of Optimality on EDF Scheduling in Sink-tree Packetized Networks

 

Abstract: Earliest Deadline First (EDF) scheduling, is known to obtain the optimality of deterministic delay performance upon the single link. However, due to the generality of the network with multiple nodes and multiple flows transmitted within it, the optimal online scheduling is impossible. In this paper, we prove that EDF can still provide the optimal delay performance in a class of practical multiple-nodes-and-multiple-flows network scenarios, such as 5G Cloud VR/AR applications in up-link cases, namely in sink-tree networks multiple flows sharing the root node as the same destination node. The proof uses the delay-based schedulability region to quantify the performance of different scheduling policies. Finally, the proof indicates that EDF can achieve the largest schedulability region in sink-tree networks.

Title: Indirect Line-of-Sight Free-Space Optical Communications Using Diffused Reflection

 

Abstract: Free-space optical communication (FSOC) has been proved to achieve the highest data-rate communications, and yet, its long-time adoption remains reserved to very selective applications. A culprit of the limited adoption of FSOC is its point-to-point link connectivity that results from the required: a) the direct Line-of-Sight (LoS) between transmitter and receiver and b) the fine alignment of the transceivers of the communicating stations. Indirect LoS FSOC (ID-FSOC) is an alternative to FSOC where a transmitter and receiver might not be in direct LoS of each other but to a diffuse reflector. Such a reflector not only helps to cover out-of-sight areas but also converts the optical link onto a broadcast channel where one station may communicate with all other stations that have LoS to the reflector.  Here, we discuss some of the properties of this novel paradigm and argue that it may represent a new facet of free space of optical communications that provides a greater range of applications for high-speed data communications.

Title: Multi-path Transmission Scheme Based on Segment Control in Low-Earth-Orbit Satellite Network

 

Abstract: Because of the challenges brought by the high dynamic topology of satellite networks to the transport layer, this paper is mainly devoted to a multi-path transmission control protocol (MPTCP) path selection scheme based on segment control technology and software-defined network (SDN). We describe the signaling interaction mode of MPTCP and the process of segment control technology applied in the satellite network. According to the requirements of real-time and accuracy of data transmission, we consider the link delay, stability, and packet loss rate, and construct the scheme as a maximum-flow minimum- cost problem. The experimental results show that the proposed scheme can meet the low delay requirements of delay-sensitive traffic flow, improve bandwidth utilization, and ensure more efficient and reliable data transmission.

Title: Asymmetric Addressing Structures in Limited Domain Networks

 

Abstract: Different industry verticals require their network domains to describe their optimized application control and behavior through custom protocols. Such local protocols are necessary because adapting specific behaviors using current general-purpose network paradigms often leads to constrained design decisions since the IP does not provide necessary customization with its existing format. At the same time, with the growth in Industrial Internet and IoT, there is a need for convergence between the standard Internet and proprietary protocols. In this regard, network addresses are key to representing application semantics or a device’s capability, but the current IP address structure does not sufficiently capture these artifacts. We propose the use of New IP shipping specification to accommodate a diverse set of local protocol requirements in a well-structured user-defined address scheme and its effective integration and adaptation to the IP for opaque connectivity over the Internet.

Title: On Control and Data Plane Programmability for Data-Driven Networking

 

Abstract: The soaring complexity of networks has led to more and more complex methods to manage and orchestrate efficiently the multitude of network environments. Several solutions exist, such as OpenFlow, NetConf, P4, DPDK, etc., that allow network programmability at both control and data plane level, driving innovation in many focused high-performance networked applications. However, with the increase of strict requirements in critical applications, also the networking architecture and its operations should be redesigned. In particular, recent advances in machine learning have opened new opportunities to the automation of network management, exploiting existing advances in software-defined infrastructures. We argue that the design of effective data-driven network management solutions needs to collect, merge, and process states from both data and control planes. This paper sheds light upon the benefits of utilizing such an approach to support feature extraction and data collection for network automation.
