  • The Next 700 Network Programming Languages

    Nate Foster (Cornell University)

    • Abstract: Specification and verification of computer networks has become a reality in recent years, with the emergence of domain-specific programming languages and automated verification tools. But the design of these languages and tools has been largely ad hoc, driven more by the needs of applications and the capabilities of hardware than by any foundational principles. This talk will present NetKAT, a language for programming networks based on a well-studied mathematical foundation, Kleene Algebra with Tests (KAT). The talk will describe the design of the language, its semantic underpinnings, and extensions with features to support stateful and probabilistic programming.

      NetKAT is joint work with colleagues at Cornell, Facebook, Inhabited Type, Princeton, Samsung, UCL, and UMass Amherst.

  • The ONF Intermediate Representation for Networking-specific Programming Languages

    Gordon Brebner (Xilinx, Inc.)

    • Abstract: There has been much recent research around domain-specific programming languages for packet processing, notably the P4 language. There is a wide variety of targets for such languages, including CPUs, various NPUs, programmable switch chips, and FPGAs. Following established practice in normal programming language compilation to avoid the m*n proliferation of compilers for m languages to n targets, through the use of intermediate representations such as LLVM, the Open Networking Foundation started the PIF (Protocol Independent Forwarding) activity to define a domain-specific intermediate representation for networking. This talk will review the work of the PIF group, and discuss the candidate intermediate representation (BIR: the "B" Intermediate Representation) that has been developed.

       

    • Bio: Prof. Gordon Brebner is a Distinguished Engineer at Xilinx, Inc., the world's leading provider of all-programmable FPGAs and SoCs.

  • Interactive Query for Dynamic Network Analytics

    Haoyu Song (Huawei Technologies)

    • Abstract: Network data plane needs to be interactively programmed in order to support Dynamic Network Analytics (DNA). We envision the high level DNA applications can be break down into a set of queries and the queries can be further compiled into incremental configurations to the data plane. We emphasize the need to define standard DNA APIs and/or query language for DNA system.

       

    • Bio: Haoyu Song is a principal architect at Huawei Technologies. He is a leading researcher on SDN programmable data plane. His current research interests span all aspects of the SDN/NFV ecosystem. He was a researcher at Bell Labs, Alcatel-Lucent before joining Huawei. He hold a doctoral degree in computer engineering from Washington University in St. Louis.

       

  • Verifying Reachability in Networks with Mutable Datapaths

    Aurojit Panda (UC Berkeley)

    • Abstract: Recent work has made great progress in verifying the forwarding correctness of networks. However, these approaches cannot be used to verify networks containing middleboxes, such as caches and firewalls, whose forwarding behavior depends on previously observed traffic. We explore how to verify reachability properties for networks that include such "mutable datapath" elements. We want our verification results to hold not just for the given network, but also in the presence of failures. The main challenge lies in scaling the approach to handle large and complicated networks, We address by developing and leveraging the concept of slices, which allow network-wide verification to only require analyzing small portions of the network. We show that with slices the time required to verify an invariant on many production networks is independent of the size of the network itself.

       

    • Bio: Aurojit Panda is a PhD candidate at UC Berkeley advised by Scott Shenker. His research largely focuses on how to simplify developing and deploying new network services.

       

  • NEMO Engine, A Model Driven Compiler to Execute User's Intent and Manage Service Lifecycle by Multi Layer State Machine

    Yinben Xia (Huawei Technologies)

    • Abstract: In last year's NetPL workshop, I introduced an intent oriented network service programming language - NEMO. This time, I will introduce NEMO's model driven compiler, which compiles intent language to real network executable interface. Second, I will introduce a multi layer state machine engine in NEMO compiler, which will handle various changes from equipments, requirement or governance policy. This engine provides an automatic change management capability for whole service lifecycle. In the last, I will update NEMO's open source implementation progress.

Call for Participation

The NetPL workshop provides a forum to bring together researchers and practitioners from the fields of programming languages, formal methods, and networking.

Recent technological trends, such as Software-Defined Networking, Network Functions Virtualization and reconfigurable networking hardware, have created an opportunity for researchers in these traditionally separate communities to collaborate, applying their diverse perspectives towards the development of novel networking applications. It is important to clarify that the scope of this workshop goes strictly beyond SDN. We aim to enable language specialists to better understand opportunities in networking, and networking specialists to better understand opportunities enabled by specially-designed languages.

The program will include invited talks from experts in the field, with an emphasis on encouraging engaging technical discussions amongst the participants.

This is the second NetPL workshop, after last year's workshop at ECOOP. All talks in the previous edition of the workshop are on YouTube.
