Existing performance comparisons of QUIC and TCP compared an optimized QUIC to an unoptimized TCP stack. By neglecting available TCP improvements inherently included in QUIC, comparisons do not shed light on the performance of current web stacks. In this ...

Performance measurement in terms of packet loss, delay, and jitter is key in modern packet switched networks. These values give a clear indication of the quality of service (QoS) perceived by users, thus being helpful to service providers to properly ...

DNS is a critical service for almost all Internet applications. DNS queries from end users are handled by recursive DNS servers for scalability. For convenience, Internet Service Providers (ISPs) assign recursive servers for their clients automatically ...

Virtually every Internet communication typically involves a Domain Name System (DNS) lookup for the destination server that the client wants to communicate with. Operators of DNS recursive resolvers---the machines that receive a client's query for a ...

We measure the effect of DoH and DoT on name resolution performance and content delivery. We find that although DoH and DoT response times can be higher than for conventional DNS (Do53), DoT performs better than DoH and Do53 in terms of page load times. ...

This paper proposes and evaluates a new approach, based on Software Defined Networking (SDN), to secure the IPv6 Neighbor Discovery Protocol (NDP) message exchange and make the Stateless Address Autoconfiguration safer. We created an SDN application on ...

Extending fairness to multiple timescales creates the right incentives for users and provides better QoE for short sessions, e.g. for web page download. In this paper, we show how to define and implement multi-timescale fairness among flows independently ...

In this paper, we report on our investigation of how current local time is reported accurately by devices connected to the internet. We describe the basic mechanisms for time management and focus on a critical but unstudied aspect of managing time on ...

The Internet was not designed with security in mind. A number of recent protocols such as Encrypted DNS, HTTPS, etc. target encrypting critical parts of the web architecture, which can otherwise be exploited by eavesdroppers to infer users' data. But ...

Container systems (e.g., Docker) provide a well-defined, lightweight, and versatile foundation to streamline the process of tool deployment, to provide a consistent and repeatable experimental interface, and to leverage data centers in the global cloud ...

Many multi-domain use cases can benefit substantially from network information exposure, but also introduce new, key requirements that existing exposure solutions, such as the Application-Layer Traffic Optimization (ALTO) protocol, do not satisfy. In ...

Nowadays, Internet actors have to deal with a strong increase in Internet traffic at many levels. One of their main challenge is building high-speed and efficient networking solutions. In such a context, kernel-bypass I/O frameworks have become their ...

When programming network functions, changes within a packet tend to have consequences---side effects which must be accounted for by network programmers or administrators via arbitrary logic and an innate understanding of dependencies. Examples of this ...
