Real-time collaborative editing gives users the illusion that they are editing the same document, but in reality, each collaborator makes edits to their own local replica of the document to ensure a low-latency typing experience. Each user's local operations must then be transmitted to remote collaborators and integrated so that the contents of every replica remain equivalent and that the intentions behind each participant's edits are preserved. This challenge has been the focus of nearly...

We all know how to program CPUs, making it easy to prototype new ideas, build new applications, and share them with others. Today it is commonplace to program not just CPUs, but almost any domain-specific processors, such as GPUs, DSPs, and even machine-learning accelerators (e.g., TPUs). Unfortunately networking has long been an exception to this trend; the network data plane -- packet processing -- has been dictated by fixed-function switching chips, which help...
