Networking

Computer networks enable information to move across the globe. They are foundational to the world we live in and to the vast majority of our work. Our interests include transport and routing protocols, network security, p2p systems, publish-subscribe protocols, and network monitoring and simulation.

IPFS-FAN: A Function-Addressable Computation Network
Permissionless computation is one of the missing pieces in the web3 stack in order to have all the tools needed to “decentralise Internet services”. There are already proposals to embed computation in decentralised networks like smart contracts, or blockchain networks for computational offloading.

Accelerating content routing with Bitswap: A multi-path file transfer protocol in IPFS and Filecoin
Bitswap is a Block Exchange protocol designed for P2P Content Addressable Networks. It leverages merkle-linked graphs in order to parallelize retrieval and verify content integrity. Bitswap is being used in the InterPlanetary File System architecture as the main content exchange protocol, as well as in the Filecoin network as part of the block synchronisation protocol.

GossipSub: Attack-resilient message propagation in the Filecoin and ETH2.0 networks
Permissionless blockchain environments necessitate the use of a fast and attack-resilient message propagation protocol for Block and Transaction messages to keep nodes synchronised and avoid forks. We present GossipSub, a gossip-based pubsub protocol, which, in contrast to past pubsub protocols, incorporates resilience against a wide spectrum of attacks.

Automating QUIC interoperability testing
We present QuicInteropRunner [1,2], a test framework for automated and on-demand interoperability testing between implementations of the QUIC protocol [3]. We describe the key constraints and insights that defined our work, the recent innovations that made the framework possible, a high-level overview of our design, and a few exemplary tests.

Decentralising the Internet with IPFS and Filecoin (DI2F) workshop at IFIP Networking 2021: Call for Contributions
Since the InterPlanetary File System (IPFS) was first introduced in a 2014 whitepaper, interest from the research community on improving and building on its protocol stack has been steadily growing. A search for “IPFS networking” on Google Scholar now returns over 1500 results, and that is just a fraction of the relevant publications.

ResNetLab 2020 in review: we love it when a plan comes together
We hope you spent some fantastic time with your loved ones during the holiday season. With the time to pause, rest, and reflect – and with the goal of kicking off 2021 in the best way possible – we decided to capture ResNetLab’s 2020 highlights, share what we’ve learned, and describe what we will be focusing on in 2021.

Beyond Swapping Bits: project review (and preview!)
If you have been following along for the past three months (1, 2, 3, 4), you know that we in ResNetLab started the Beyond Bitswap project with one goal in mind: to drive speed-ups for file-sharing in IPFS.

Our Bitswap nodes have become “jumping inspectors” (updated)
A few weeks ago, we shared how we have taught our Bitswap nodes to jump. If you recall from that post, the content discovery range extension gained came at the expense of an increased number of duplicate blocks exchanged in the network.

Teaching Bitswap nodes to jump
By now you may have heard about ResNetLab’s research endeavour to drive speed-ups on file transfers: Beyond Swapping Bits. Our recent blog post, “Honey, I shrunk our libp2p streams”, considers how adding compression to libp2p could lead to significant bandwidth savings.

"Two ears, one mouth": how to leverage bitswap chatter for faster transfers
As part of ResNetLab’s research endeavour to drive speed-ups on file transfers, Beyond Swapping Bits, we present a new contribution to IPFS Bitswap protocol. We argue that Bitswap is currently discarding a wealth of information that could be used to its benefit, improving retrieval success and minimizing the latency to retrieve content.

A brief history of (re)building the Internet
The Internet began life as a military network engineered for resilience in the face of a nuclear attack. That’s right—the same network you use to check on your friends and share cat photos has at its core a structural pattern intended to survive a nuclear exchange long enough to mutually assure destruction with the USSR.

How content addressing can solve streaming challenges as networks are overloaded
Given the mass migration to remote work we’ve seen in recent months, you’d think the internet would be collapsing under the added strain. Yet precisely the opposite has happened. As experts have observed, the internet isn’t buckling under added traffic; it’s thriving.

A new lab for resilient networks research
Resiliency is at the core of systems that are capable of standing the test of time, providing unshakable access for the many generations to come. A resilient system or network is fundamentally uncompromised by an isolated failure or network split.
