Challenges and Research Directions for the Future Internetworking

Abstract

Abstract-We review the main challenges and survey promising techniques for network interconnection in the Internet of the future. To this end, we first discuss the shortcomings of the Internet's current model. Among them, many are consequence of unforeseen demands on the original Internet design such as: mobility, multihoming, multipath, and network scalability. These challenges have attracted significant research efforts in the latest years because of both their relevance and complexity. In this survey, for the sake of completeness, we cover several new protocols for network interconnection spanning both incremental deployments (evolutionary approach) and radical proposals to redesign the Internet from scratch (clean-slate approach). We focus on specific proposals for future internetworking such as: Loc/ID split, flat routing, network mobility, multipath and content-based routing, path programmability, and Internet scalability. Although there is no consensus on the future internetworking approach, requirements such as security, scalability, and incremental deployment are often considered.

A fast and accurate threat detection and prevention architecture using stream processing

“…Communication networks transfer an increasing amount data due to billions of users and devices, creating several challenges for threat detection. [1][2][3] Moreover, denial of service (DoS) attacks already reached more than 1.35 terabits per second 4 and the longest in 2016 lasted 197 h. 5,6 Network providers have to handle millions of data streams in real-time, 7 and attacks can attempt to hide in this deluge of information; therefore, detecting network attacks is actually a "big data" problem and requires modern processing frameworks. Besides, the time it takes to detect an attack is essential, and if detection takes too long, irreparable damages will occur.…”

Multi-Objective Third-party Approach for Service Class Mapping among Multiple Providers in the Internet

“…Recent trends in Internet development including cloud computing, mobility, content distribution, Internet of things, and the big data paradigm pose new architectural challenges for network interconnection in the future Internet [1]. Enhanced solutions for quality of service (QoS) provisioning are still needed, particularly regarding end-to-end (E2E) service negotiation, performance monitoring and measurements for inter-domain performance assessment.…”

Partial path extension scheme for mobile content source in content-centric networking (CCN)

“…Instead, they make much of how fast and reliably the requested content can be accessed. However, to meet such trends, the current Internet inherently requires additional operations and control overheads, such as multi-staged address resolution, add-on security, frequent location updates, and congestion control [4,5]. Many research efforts have attempted to adjust and redesign the current Internet's content exchange model causing a lot of signaling overhead, especially in the case of mobile devices.…”
