TL;DR: This paper presents an in-depth analysis of the hardware infrastructure, southbound and northbound application programming interfaces (APIs), network virtualization layers, network operating systems (SDN controllers), network programming languages, and network applications, and presents the key building blocks of an SDN infrastructure using a bottom-up, layered approach.

TL;DR: Software-Defined Networking (SDN) as discussed by the authors is an emerging paradigm that promises to change this state of affairs, by breaking vertical integration, separating the network's control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network.

TL;DR: This paper presents a new publicly available dataset from GÉANT, the European Research and Educational Network, which consists of traffic matrices built using full IGP routing information, sampled Netflow data and BGP routing data of the GÉant network, one per 15 minutes interval for several months.

TL;DR: The Elastic sketch is proposed, which is adaptive to currently traffic characteristics, generic to measurement tasks and platforms, and implemented on six platforms to process typical measurement tasks.

TL;DR: This is the first study using a ground truth showing that the overly fine granularity of database entries makes their accuracy worse, not better, and quantifies the accuracy of geolocation databases on a large European ISP based on ground truth information.
