SIGCOMM Networking Systems Award

The SIGCOMM Networking Systems Award is awarded to an institution or individual(s) to recognize the development of a networking system that has had a significant impact on the world of computer networking.
2019: Multipath TCP implementation in the Linux kernel
Multipath TCP [RFC6824] is a recent TCP extension that enables the utilisation of multiple paths to exchange data over a single TCP connection. The development of Multipath TCP started in 2008 when a group of researchers convinced the IETF to work on developing multipath extensions to TCP. At the beginning, the IETF was skeptical. The implementation was developed in parallel with the standardisation work. Early experiments with this implementation revealed that deployed middleboxes were hindering the extensibility of TCP. A detailed measurement study confirmed those problems [Honda11]. Despite the interferences from middleboxes and thanks to the feedback from the implementation, the mptcp working group managed to ensure the deployability of Multipath [NSDI12]. Since then, various research groups have used this implementation to perform measurements, design extensions to Multipath TCP such as new congestion control schemes, ... Citations to RFC6824 or NSDI12 illustrate the impact of Multipath TCP on the research community.
This implementation has also played a key role in the adoption of Multipath TCP within industry [RFC8041,IETFJ16]. Since 2013, Apple uses Multipath TCP on iOS, initially for the Siri application and since last year for any application. The main benefit that they see with Multipath TCP is the ability to support fast handovers from WiFi to cellular when the user is moving. Although Apple developed their own stack, the availability of the Linux implementation reassured them for the stability of the protocol and the possibility of using it on Linux servers. Korea Telecom has convinced Samsung and LG to use this Multipath TCP implementation in all their high-end smartphones to bond WiFi and cellular for premium users. The main benefit that they see with Multipath TCP is the ability of increasing the bandwidth offered to endusers. Another growing use case are the hybrid access networks. To provide higher bandwidth services, a growing number of network operators are deploying solutions to combine their xDSL and 4G networks. This is possible thanks to the availability of a Multipath TCP implementation in the Linux kernel which is the default operating system for xDSL CPE routers. Broadcom and intel include the Linux Multipath TCP implementation in the Software Development Kit that they provide for CPE vendors. Tessares, Soft@home and OVH have deployed hybrid access network services that rely on this implementation. Those hybrid access networks are typically deployed in rural areas where xDSL performance is poor due to line distance.
This implementation is freely available from The development of new features is discussed on the mptcp-dev mailing list,

2018: The Akamai Content Delivery Network (CDN)
The Akamai CDN pioneered the concept of a content distribution network, combining numerous technical innovations with an equally innovative business model that simultaneously met the needs of multiple stakeholders (site owners, ISPs, and users).  Akamai’s technical contributions include a system for mapping clients to the best CDN server, active probing to create a latency model of the Internet, and a dynamic control system that provides load balancing and fault tolerance. In particular, the paper "Consistent Hashing and Random Trees: Distributed Caching Protocols for Relieving Hot Spots on the World Wide Web" (STOC ‘97) provided a deep algorithmic basis, introducing random cache trees for load-balancing, and consistent hashing to minimize churn. With its enormous worldwide scale, the Akamai CDN is an exemplary study in translating research results into a successful operational system.
