This technology opened the door for efficient programming in the operating system, especially in its network stack. However, its applicability is not limited to the Linux kernel. Various efforts leveraged the eBPF Instruction Set Architecture (ISA) as the basis of other networking related use cases outside of the Linux kernel. This paper focuses on the pluginized protocols' use case such as PQUIC and xBGP where the eBPF ISA serves as the basis to execute plugins providing per-session protocol behavior. It first quickly describes how the Linux kernel builds around this eBPF ISA to provide enhanced in-kernel network programmability. Then, the paper considers the case of pluginized protocols. Leveraging eBPF outside of the Linux kernel environment requires complementing the eBPF ISA to meet the pluginized protocols' requirements. This paper details these integration efforts. Based on the lessons learned from these, it finally concludes by an applicability discussion of the eBPF ISA to other use cases.</p>","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"260 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139924797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are three main factors at play here. Given the timing of our SIGCOMM conferences, summer is a low period for submissions to CCR. Then, as CCR is selective and its scope limited to timely works relevant to our community, few technical papers make it above our bar. Finally, I have witnessed a healthy shift away from technical papers towards more thought-provoking editorials over the last few years. We have enough conference and journals for technical papers to find an appropriate venue. On the other hand, our conferences and journals, due to their selective nature and the overly critical nature of the reviewing process, do not lend themselves to welcome thought-provoking and contentious contributions.

As context, we note that the Internet was originally designed to provide a simple universal service - global end-to-end packet delivery - on which a wide variety of end-user applications could be built. The early Internet supported this packet-delivery service via an interconnected collection of commercial Internet Service Providers (ISPs) that we will refer to collectively as the \"public Internet.\" The Internet has fulfilled its packet-delivery mission far beyond all expectations and is now the dominant global communications infrastructure. By providing a level playing field on which new applications could be deployed, the Internet has enabled a degree of innovation that no one could have foreseen. To improve performance for some common applications, \"enhancements\" such as caching (as in content-delivery networks) have been gradually added to the Internet. The resulting performance improvements are so significant that such enhancements are now effectively necessary to meet current content delivery demands. Despite these tangible benefits, this document argues that the way these enhancements are currently deployed seriously undermines the sustainability of the public Internet and could lead to an Internet infrastructure that reaches fewer people and is largely concentrated among only a few large-scale providers. We wrote this document because we fear that these developments are now decidedly tipping the Internet's playing field towards those who can deploy these enhancements at massive scale, which in turn will limit the degree to which the future Internet can support unfettered innovation. This document begins by explaining our concerns but goes on to articulate how this unfortunate fate can be avoided. To provide more depth for those who seek it, we provide a separate addendum with further detail.</p>","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"48 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139924799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this editorial, I discuss why SmartNICs are an especially powerful form factor for improving I/O intensive applications, and how their position in the dataplane enables them to take on central role in managing I/O. Rather than focusing on the benefits of individual offloads, this paper aims to explore the position of SmartNICs in the overall system integration of datacenter servers at the hardware and software level. I argue that SmartNICs should be viewed as 'data movement controllers' (NIC-DMCs) which are responsible for tasks involved in moving data between network, CPU, accelerators, and other endpoints: multiplexing/steering, interfacing between protocols, and enforcing I/O policies. I then enumerate open questions in how the hardware and software systems of the future will evolve to accommodate a dedicated NIC-DMC which is independent of the CPU complex.</p>","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"54 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139924687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this paper offers an overview of the privacy-preserving mechanisms for layer 3 (i.e. IP) and above that are currently under standardization at the IETF. This includes encrypted DNS at layer 5 classified as DNS-over-TLS (DoT), DNS-over-HTTPS (DoH), and DNS-over-QUIC (DoQ) where the underlying technologies like QUIC belong to layer 4. Followed by that, we discuss Privacy Pass Protocol and its application in generating Private Access Tokens and Passkeys to replace passwords for authentication at the application layer (i.e. end-user devices). Lastly, to protect user privacy at the IP level, Private Relays and MASQUE are discussed.
