Keynote title: Are Network Layer Enhancements Needed for Supporting Emerging Applications?
Abstract: The Internet protocol suite has withstood numerous challenges that emerging applications have continually posed over the last several decades, and has admirably served the needs of our information driven society. The fundamental principles behind the design continue to serve us well even in these challenging times. Given this background, is there a reason to reconsider enhancements to the network layer in the context of even newer applications that are likely to emerge as we grow more and more dependent on networking.
I will discuss a few applications that are gaining traction that can be substantially helped by a network layer more responsive to application needs in terms of latency, flexible naming and service features. Vehicular applications, rich 360-degree video distribution and augmented reality are emblematic of such emerging applications, and I will discuss the network layer features that these applications could use to improve their capabilities.

Title: Qualitative Communication Via Network Coding and New IP
Abstract: Qualitative Communication has been proposed to reduce the granularity of packet dropping due to congestion, from packet level to chunk level, which can significantly improve the user experienced latency and reduce the number of packet re-transmissions under the reliable transmissions. This paper proposes an approach to achieve Qualitative Communication by applying random linear network coding to chunks in packet payload. With the help of New IP framework, the network can efficiently perform packet wash in order to retain as many chunks in the packets as possible when congestion happens. The paper proposes several advanced features to further boost the benefits of this approach.

This presentation will talk about a framework to support such guaranteed services. It is based on a scalable control protocol and a backward compatible data plan. The new control protocol could provide flow-based service negotiation and program hardware accordingly. The new data plane can guarantee different services for different flows with agreed Service Level Objectives, and can coexist with the traditional best effort and DiffServ services

Keynote Title: FlexNGIA – Drawing the Architecture of the Next-Generation Tactile Internet
Abstract: From virtual reality and teleportation, to telepresence, augmented reality, holograms, and remotely controlled robotics, these future network applications promise an unprecedented development for society, economics and culture by revolutionizing the way we live, learn, work and play. Unfortunately, today’s Internet falls short when it comes to providing the stringent performance requirements imposed by such applications. This is due to several fundamental limitations in the design of the current network architecture and communication protocols. As a result, there is a pressing need to rethink the network architecture and protocols, and efficiently harness recent technological advances in terms of virtualization and network softwarization to design the Tactile Internet of the future.
In this talk, we start by analyzing the characteristics and requirements of future networking applications and highlight the limitations of the current network architecture and protocols. We then draw a rough sketch of FlexNGIA, a Flexible Next-Generation Internet Architecture that is able to satisfy the requirements of future Internet applications and services. We also discuss through some use-cases how FlexNGIA could ensure the service level guarantees required by some of the future network applications.

Title: Deep Reinforcement Learning for NFV-based Service Function Chaining in Multi-Service Networks
Abstract: With the advent of Network Function Virtualization (NFV) techniques, a subset of the Internet traffic will be treated by a chain of virtual network functions (VNFs) during their journeys while the rest of the background traffic will still be carried based on traditional routing protocols. Under such a multi-service network environment, we consider the co-existence of heterogeneous traffic control mechanisms, including flexible, dynamic service function chaining (SFC) traffic control and static, dummy IP routing for the aforementioned two types of traffic that share common network resources. Depending on the traffic patterns of the background traffic which is statically routed through the traditional IP routing platform, we aim to perform dynamic service function chaining for the foreground traffic requiring VNF treatments, so that both the end-to-end SFC performance and the overall network resource utilization can be optimized. Towards this end, we propose a deep reinforcement learning based scheme to enable intelligent SFC routing decision-making in dynamic network conditions. The proposed scheme is ready to be deployed on both hybrid SDN/IP platforms and future advanced IP environments. Based on the real GEANT network topology and its one-week traffic traces, our experiments show that the proposed scheme is able to significantly improve from the traditional routing paradigm and achieve close-to-optimal performances very fast while satisfying the end-to-end SFC requirements.

Title: 5G/B5G: Role of Fixed Networks (Transport Network Requirements, Challenges and Beyond)
Abstract: Apart from the stringent transport network requirements from 5G uRLLC, new mobility scenarios and rapid disaggregation in front/mid haul as well as core networks are putting unprecedented demands on 5G/B5G transport network infrastructure. While IP/MPLS technologies served well in the existing deployments the new requirements are pushing best-effort Internet technology to its limit. Some of the new requirements like low-latency, high-reliability, jitter, and zero-packet loss are critical for meeting the new service requirements for 5G/B5G. Even if edge computing is factored, lack of the above capabilities in the underlay transport network is an impediment for lot of the envisioned services in these networks.
This talk highlights the transport network routing and traffic engineering requirements in evolving X-Haul in 5G/B5G networks, gaps in existing matured underlays like IPv6/MPLS and highlights how some of the activities happening in various SDOs still fall short of core requirements. In order to address the new challenges, this talk focuses on long term research needed for Future Internet Data planes to bring high-precision services needed for 5G/B5G deployments. This talk also highlights, how newly proposed Internet data planes and transport like new IP architecture and protocols can be relevant Invited Session on Blockchain in this space.

Title: Using functional Bloom filters for name lookup in NDN
Abstract: Named data networking (NDN) technology has been proposed as a future Internet architecture for effectively handling this ever-increasing network traffic. In order to realize the NDN, high-speed lookup algorithms for a forwarding information base (FIB) are crucial. This talk describes a level-priority trie (LPT) and a 2-phase Bloom filter architecture implementing the LPT. The proposed 2-phase Bloom filter architecture is sufficiently small to be implemented with on-chip memories for FIB tables with up to 100,000 name prefixes. Hence, the proposed structure enables high-speed FIB lookup.

Title : Using Dual-load Bloom filter for name lookup in NDN
Abstract : The current Internet is based on a host-centric structure, and therefore does not efficiently transmit large capacity and repeatedly requested traffic. To solve this problem, various proposals for the future Internet have been made with the goal of overcoming inefficiencies caused by changes in the type of traffic currently being handled by the Internet. Named data networking (NDN) technology is a promising candidate for the future Internet. A name prefix trie (NPT) and the path-compression NPT (PC-NPT) should be implemented in off-chip memory because the number of content names stored in the FIB table is excessively large. We propose the use of a PC-NPT with a Dual-load Bloom filter (BF) for packet forwarding in NDN. The proposed BF allocates 2 bits per cell such that the cell can have one of four values: 0, 1, 2, and X. The proposed structure stores two information (skip value and name prefixes) in one Bloom filter, and each information is programmed as different values. When Bloom filter programs each information using two bits of memory per cell, different values can be set for each programming phase, making it possible to identify the exact meaning of the corresponding cell when queried.

Title: FIB Sharing and Cache Sharing using Bloom filters in NDN
The major portion of the Internet bandwidth is now being used for content distribution
like video streaming. The conventional Internet infrastructure, which is based on a
host-to-host communication model, is not efficient for content distribution. In order to
accommodate today’s communication needs, Named Data Networking (NDN) has
been introduced as a future Internet architecture. NDN technology has two main
characteristics: name-based content retrieval and in-network caching. There are many
research challenges for the realization of NDN. This talk presents two methods of
information sharing using Bloom filters in NDN: (1) Content Store sharing, which shares
cache summaries with neighboring routers to increase the diversity of cached contents
in a network as a whole, and (2) FIB table sharing, which reduces the traffic and the
size of the FIB tables.
