Today's large content providers (CP) are busy building out their service infrastructures or "peering edges" to satisfy the insatiable demand for content created by an ever-expanding Internet edge. One component of these serving infrastructures that features prominently in this build-out is their connectivity fabric; i.e., the set of all Internet ...
Keywords: content delivery networks, content providers, peering

Virtual switches, like Open vSwitch, have emerged as an important part of today's data centers. They connect interfaces of virtual machines and provide an uplink to the physical network via network interface cards. We discuss usage scenarios for virtual switches involving physical and virtual network interfaces. We present extensive black-box ...

For many years, the research community, practitioners, and regulators have used myriad methods and tools to understand the complex structure and behavior of ISPs from the edge of the network. Unfortunately, the nature of these techniques forces the researcher to find a balance between ISP-coverage, user scale, and accuracy. In ...

As ISPs face IPv4 address scarcity they increasingly turn to network address translation (NAT) to accommodate the address needs of their customers. Recently, ISPs have moved beyond employing NATs only directly at individual customers and instead begun deploying Carrier-Grade NATs (CGNs) to apply address translation to many independent and disparate ...

Ever growing demand for network bandwidth makes computer networks an area of constant development and fast adjustments. The steady change makes good performance assessments equally necessary and challenging. This development motivated us to revisit the established benchmarking methodology. We provide an overview of the state-of-the-art in router benchmarking, the currently ...

Driven by the expected benefits, SDN techniques prepare to dare the leap from datacenter and small area networks to larger networks. SDN becomes more and more interesting in ISP networks, where new concerns about scalability, resilience and legacy functionality arise. Therefore, we analyze RouteFlow, a promising approach to SDN, that ...

We present MoonGen, a flexible high-speed packet generator. It can saturate 10 GbE links with minimum-sized packets while using only a single CPU core by running on top of the packet processing framework DPDK. Linear multi-core scaling allows for even higher rates: We have tested MoonGen with up to 178.5 ...

High-speed network cards supporting 10 or 40GbE (Gigabit Ethernet) are available today. Software frameworks for high-speed packet reception and transmission were created to exhaust the performance of these cards. However, these frameworks are not applicable as general-purpose solution. Thus, it is necessary to revisit general purpose network IO software that ...

Network stacks currently implemented in operating systems can no longer cope with the packet rates offered by 10 Gbit Ethernet. Thus, frameworks were developed claiming to offer a faster alternative for this demand. These frameworks enable arbitrary packet processing systems to be built from commodity hardware handling a traffic rate ...

Latency has a high impact on the user satisfaction in real-time multiplayer games. The network between the client and server is, in most cases, the main cause for latency and out of the scope of the game's developer. But the developer should avoid introducing unnecessary delays within his responsibility; i.e. ...

Middleboxes are an essential part of today's networks since they allow to introduce additional functionality without having to change end-hosts. Network Address Translation (NAT) has been the number one choice for coping with the address depletion problem of IPv4. Although NAT introduces many problems for existing applications it can be ...
