A Variegated Study of 5G Services: Challenges, Opportunities, and Application Innovations

Abstract: 5G is expected to support sub-millisecond latency as well as a throughput of up to 20 Gbps – a 100x improvement compared to 4G/LTE. However, there exists a vacuum in understanding how 5G performs “in the wild” and whether it can fulfill its promises. In this talk, I will describe our research thrust of 5G networks since early 2019, when Minneapolis became one of the first two U.S. cities that received commercial 5G deployment. Over the past 3 years, we have experimented with more than 100 TB of 5G data and traveled more than 8,000 km for drive tests. Our studies revealed a complete landscape of 5G across several key dimensions – network performance, power characteristics, mobility management, and application quality-of-experience (QoE), to name a few, with their critical tradeoffs quantitatively revealed. I will then talk about our development of a learning-based framework for accurate 5G performance prediction and how we innovate emerging applications such as virtual/mixed reality (VR/MR) to improve their QoE on 5G networks.

Accepted Papers

Behavior-decoupled Labeling Mechanism in Generalized SRv6

Abstract: In this paper, we study the problem of compression efficiency of SRH (Segment Routing Header) in G-SRv6 (Generalized SRv6). We propose the Function-decoupled Segment Routing Mechanism (FDSRM) to optimize the SID list in SRH while ensuring that the routing policy decision would not be affected. FDSRM logically decouples the functions of SID/G-SID according to the function in routing decision and instruction indication. Based on FDSRM, we propose a mathematical optimization framework that leverages the LSTM neural network to optimize the SID allocation to adapt to future traffic. Simulation results indicate that FDSRM can improve the probability of SRH compression by 50.86\%, and compress more than 24.50 bytes when the hop count is greater than 20.

Delay Laxity-Based Scheduling with Double-Deep Q-Learning for Time-Critical Applications

Abstract: In this paper, we propose a novel delay-aware selective admission and scheduling algorithm for time-critical applications to guarantee the delay requirement of each packet in a single-hop downlink network. We consider a series of priorities among packets. To avoid always starving low-priority packets, we define a delay-laxity concept and introduce a new output gain model as our network utility function. In this context, we formulate a multi-objective optimization problem that minimizes the average queue backlog and maximizes the average network utility under the constraints of guaranteeing per-packet delay and achieving fairness among users. To solve this problem, we model our problem as a Markov Decision Process and propose a Double Deep Q Network-based algorithm to learn the optimal policy. Simulation results show that the proposed algorithm can achieve significant improvements in average delay, delay-outage drop rate, and goodput compared with the existing stochastic schemes. Moreover, the proposed algorithm outperforms the conventional Q-learning algorithm in terms of reward and learning speed.

Semiring Algebraic Structure for Metarouting with Automatic Tunneling

Abstract: Metarouting models routing protocols in the form of an algebraic structure called routing algebra. It aims to help designing or validating routing protocols. Most research work on routing algebras have been applied to routing protocols used in networks having a single addressing and forwarding protocol. In this context, some of the basic algebraic structures used are semirings. In this paper, we define a new algebraic structure for dealing with networks containing multiple forwarding protocols, which may induce many (and possibly nested) tunnels. We widely generalize the semiring structure for modeling the routing problem with automatic tunneling. We define a new model of routing algebra with tunneling. It is defined as a semi-direct product of two structures, the well-know shortest paths algebra and a new proposed valid paths algebra. It is isotonic and non-monotonic with a partial order. We show that it has a fixed point and we prove the iterative convergence to the optimal solution of the valid shortest paths problem.

New IP based semantic addressing and routing for LEO satellite networks

Abstract : This document proposes a method of addressing and routing for massive Low Earth Orbit (LEO) satellite constellations. It is based on the concepts and technologies of New IP. LEO satellite networks can be used for Internet access and for the Non-Terrestrial Network (NTN) integration with 5G and beyond. Our new addressing method leverages the characteristics of satellites with known orbit elements; and simplifies the satellite identification by using limited indexes. The new routing method combines semantic addressing with source routing and generates a new semantic routing scheme. Compared with traditional methods, the new proposal dramatically reduces the workload in satellite, such as table size, TCAM (Ternary Content-addressable Memory) lookups, and packet header size. Thus, it is more suitable to network in space where the harsh environment will restrict the hardware performance, power consumption, link bandwidth and system complexity.

Tiny In-Network Transport for High Precision INdustrial Communication

Abstract: The design of a transport protocol for high precision industrial networks is a complex problem since the industrial applications are resource-critical, time-critical, session-less, and safety-critical. These requirements make existing end-to-end transport mechanisms unsuitable for use in the industry verticals that require control-systems type communication. This paper proposes a lightweight, connection-less, and reliable protocol called TinTin. It utilizes the in-network capabilities to compensate for end device constraints. The mechanisms adopted in TinTin aim to reduce the communication overheads associated with well- known connection-oriented protocols. This paper discusses the design considerations of TinTin in detail and presents an early stage proof-of-concept implementation of TinTin with New IP.

Supporting Dynamic Secure Interdomain Routing

Abstract: Path aware networking (PAN) is an approach that allows endpoints to participate in the end-to-end path selection, letting them choose paths best suited for each application. This approach offers numerous potential benefits including rapid fail-over, concurrent use of parallel paths, and QoS enabled networks, even spanning multiple domains. The dynamic interconnection of different autonomous systems (ASes) in path aware networks offers both challenges and opportunities for network service providers, which in turn provide opportunities for traffic engineering previously not possible. The SCION path-aware network architecture has been designed from the ground up with security in mind, and features a trust structure that can serve as a basis for more dynamic interconnection between ASes. In this paper, we describe a prototype spot market that lets the ASes sell time-limited excess capacity, allowing buyers to divert traffic to cheaper alternatives temporarily. We believe this market allows for new opportunities both in traffic engineering and inter-domain connectivity that have not existed before. The market benefits all parties involved, as the formerly wasted bandwidth is now used, and provides additional revenue -in varying degrees- to all the participating entities.

Evolving the End-to-End Transport Layer in Times of Emerging Computing In The Network (COIN)

Abstract: The possibility of richer computing capabilities within Internet network elements, often captured as Computing in the Network (COIN), promises performance and flexibility gains to the wider Internet, akin to those seen in recent data center advances. At the same time, moving computation into the network is seemingly at odds with the fundamental end-to-end principle underlying the development of key technologies in the Internet. In this paper, we do not only argue that the latter is not the case, but we also shed light on what ‘in the network’ may or may not entail, aiming to sharpen a possible research agenda for COIN. Taking the transport layer as an example due to its typical end-to-end realization in and importance for today’s Internet, we outline key design considerations for evolving towards a COIN-enabled transport capability. By further creating linkages to existing efforts and concepts, we provide possible future directions for the design of protocols for the future Internet.
