79      <p>Core QUIC introduces a framework in which <em>any</em> Core QUIC-compliant implementation can be safely extended using dynamically loaded plugins. We demonstrated the feasibility of our approach by making two popular QUIC implementations, Cloudflare’s <code class="language-plaintext highlighter-rouge">quiche</code> and <code class="language-plaintext highlighter-rouge">quinn</code>, Core QUIC compliant.</p>

91      <p>The Internet has never connected so many devices as of today, with an increasing number of constrained/IoT devices being publicly reachable over the public Internet, and therefore scannable through IP address enumeration. This work questions the current TCP/IP architecture of the current Internet and envisions a network whose names, such as URLs, are the only information the client needs to know to reach the wanted service.</p>

106      <p><img src="/images/pubpic/xbgp.png" class="img-responsive img-margin" width="33%" style="float: left" /></p>
107      <p>How can we quickly deploy new BGP features in a network made of devices from different vendors? xBGP addresses this issue by proposing a vendor-neutral API enabling network operators to dynamically inject plugins in all xBGP-compliant implementations. We made FRRouting and BIRD xBGP-compliant and implemented different use-cases such as valley-free path checks and prefix origin validation. We also proposed a framework verifing the behavior of the injected plugins.</p>

119      <p>We revisited the extensibility model of transport protocols by using plugins. The dynamic insertion of bytecode inside a running implementation let the connection adapt to the application it serves. We managed to implement various QUIC extensions (montoring, Multipath, Datagram, Forward Erasure Correction) only with plugins.</p>
