This document provides an overview of the OpenDataPlane (ODP) framework, which aims to support application portability across diverse hardware architectures. It discusses ODP's requirements, components, structure, and governance model. The key points are: ODP provides an abstract API specification and multiple independent implementations to ensure portability across systems. It supports exploiting platform-specific capabilities without application changes. The API specification is vendor-neutral and defines functional behavior. Implementations can be open or closed source. A test suite validates conformance. Reference implementations provide easy adoption on new platforms while allowing customization. The Linaro Networking Group sponsors and maintains ODP through open design processes.

Hotplug and Virtio - Tetsuya Mukawa
This document summarizes a presentation about dynamic network function virtualization (NFV) deployment using port hotplug and virtio. It discusses the current status of port hotplug support in DPDK, including which physical and virtual network device drivers (PMDs) support it. It then outlines how NFV could be deployed dynamically using software switches, port hotplug, virtual network interfaces, and containers or VMs. Current limitations are noted, such as the lack of a PMD for NFV ports and denial of reconnection if the software switch restarts. The document concludes that upcoming DPDK releases will address some issues by adding a "vhost PMD" and container support, but denial of reconnection will still
Hyperscan - Mohammad Abdul Awal
The overall volume of Internet traffic has been growing in a tremendous rate day-by-day which also contains unwanted malicious traffic. It has been a continuous challenge for the network operators to effectively identify the threats from line rate traffic. Hyperscan is a pattern (in terms of regular expression) matching software ideal for applications such as intrusion prevention/detection system, antivirus, unified threat management, deep packet inspection systems, etc.
Hyperscan works in two phases. At first, the customer patterns are parsed and compiled into databases in terms of bytecode. During runtime, these bytecode are used to search for patterns against blocks/streams data. Hyperscan library runs entirely in software and scales with IA processors to provide the maximum throughput of 293 Gbps.
DPDK Architecture Musings - Andy Harvey
The document discusses the goals and requirements of an abstraction layer (AL) for networking applications. The AL aims to decouple innovation between network application vendors and hardware vendors to allow both sides to innovate independently. It seeks to define a common interface that supports different hardware architectures, provides offloads, and enables applications to efficiently move packets while being hypervisor agnostic and portable across systems. The requirements include functional characteristics like packet processing as well as non-functional aspects like security, performance, extensibility, and manageability.

Crossing the river by feeling the stones from legacy to cloud native applica...
Doug Smith, Red Hat, Inc, Gergely Csatari, Nokia
There is an anecdote about a tourist lost in the middle of the countryside in Ireland, who pulls over and asks a local, "How can I get to Galway from here?" To which the local, after thinking for some time, responds, "If I was going to Galway, I wouldn't start from here at all."
Cloud native application development can feel like that sometimes, especially in the telecom industry. I have an application, it's running fine on a bare metal server, and now I am expected to make it resilient, scale-out, cloud native, microservice architecture, buzzword compliant. But how do you get there from where you are?
This presentation will present the hero's quest, identifying the key constraint to cloud resiliency at each stage, and identifying measures for addressing them. By showing the evolution story from the perspective of two applications, including a real telecom application, this presentation addresses the practical problems. The approach is not "rewrite your app from scratch", it is refactoring for incremental improvements.
Doug and Gergely will address the automation of application deployment and configuration, separation of state from behaviour, clustering, handling storage for cloud native applications, monitoring and event management, and container orchestration, so that, at each step along the journey, you know what problem you are solving, and how to get to the next step from where you are.
This presentation is in addition to a series of workshops held at the summit sponsored by the Cloud Native Computing Foundation and organized by Dave Neary, and includes a short summary of the topics presented in those workshops in addition to the perspectives on how to complete the quest to cloud native applications.

Finally, it summarizes ONAP's architecture, including its design time and run time frameworks, and provides a use case
Tech Talk by John Casey (CTO) CPLANE_NETWORKS : High Performance OpenStack Ne...
OpenStack is HOT! No doubt about it. A recent survey by The New Stack and The Linux Foundation shows OpenStack as the most popular open source project ahead of other hot projects like Docker and KVM. OpenStack is now taking its rightful place as the open source cloud solution for enterprises and service providers.
To date OpenStack networking has not yet achieved the performance, scalability and reliability that many large enterprises demand. CPLANE NETWORKS solves that problem by delivering secure multi-tenant virtual networking that overcomes the limitations of the standard Neutron networking service. By making all networking services local to the compute node and achieving near line-rate throughput, CPLANE NETWORKS Dynamic Virtual Networks (DVN) delivers mega-scale networking for the most demanding application environments.
In this session John Casey will cover the basics of DVN and explain how CPLANE NETWORKS achieves "at scale" network performance within and across data centers.

How can we make sure that new code in OPNFV does not break or stop CI?
How can we ensure quick feedback for each patch-set?
With the new way to snapshot a virtual deployment it is now possible to get virtual clouds up and running in about 2 min. In addition, through low amount of disk/cpu consumption and isolation of the networking it is possible to have a very high number of virtual deployments co-existing in the same bare-metal server.

The 7 Deadly Sins of Packet Processing - Venky Venkatesan and Bruce Richardson
The document summarizes seven deadly sins of packet processing that can negatively impact performance:
1) Unpredictable branches that confuse the branch predictor. Code should guide the compiler on likely/unlikely cases.
2) Incorrect prefetching that pulls in unnecessary data or data needed by other cores, adding overhead. Hardware prefetchers often help but can also share cache lines inadvertently.
3) Per-packet operations like memory I/O and atomics that have overhead magnified at the per-packet level.
Symmetric Crypto for DPDK - Declan Doherty
The document describes the DPDK symmetric cryptography framework. It includes APIs for scheduling crypto workloads using mbuf bursts, crypto primitives like cipher and hash algorithms, crypto transforms, session management, crypto operations, operation pools, and implemented PMDs like the AES-NI multi-buffer PMD and QAT PMD. Performance tests show the QAT PMD achieving higher throughput than the AES-NI multi-buffer PMD for AES128_CBC_SHA256_HMAC. Future work includes adding asymmetric crypto and an accelerated IPsec solution.
Performance Lessons learned in vRouter - Stephen Hemminger
This document summarizes lessons learned from optimizing DPDK performance in a virtual router. It discusses assigning cores to dataplane and control plane tasks, using small sleep intervals based on activity to limit CPU usage, and updating link state and statistics periodically. It recommends techniques like avoiding system calls, mutexes, and spinlocks for performance. Profiling showed the top functions were for packet input, output, and forwarding. Optimizing the longest prefix match for routing was also discussed.
Dpdk Validation - Liu, Yong
The document discusses Intel's DPDK Validation team and their efforts to improve the quality and robustness of DPDK. It outlines their focus on features like NICs, packet framework and virtualization. It also describes moving to a continuous integration model with automated testing of each patch to DPDK and daily health reports. This is aimed to improve the development and release cycle by catching issues earlier through more frequent testing.
Packet Framework - Cristian Dumitrescu
The document discusses the DPDK Packet Framework and the ip_pipeline application generator. It describes how the framework uses ports, tables, and actions to quickly develop packet processing pipelines. It also explains how ip_pipeline allows defining packet processing applications by connecting different reusable pipeline types and mapping them across CPU cores. The framework provides a way to build high performance packet processing applications from configurable processing blocks.
Project growth & Next steps - Thomas monjalon
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow, releases endorphins, and promotes changes in the brain which help enhance one's emotional well-being and mental clarity.
Generic Resource Manager - László Vadkerti, András Kovács
The document discusses a proposed generic resource manager for the DPDK framework. It aims to provide better control and management of resources like CPU, memory, network ports and packet pools. The resource manager would track resource usage, enable migration of resources between instances, and prioritize access. It presents examples of how the manager could allocate memory domains with different configurations like default shared memory, NUMA-aware shared memory, and exclusive private memory per instance.
TRex Traffic Generator - Hanoch Haim
TRex is an open source, low cost, stateful traffic generator fuelled by DPDK. It generates L4-7 traffic based on pre-processing and a smart replay of real traffic templates. TRex amplifies both client and server side traffic and can scale to 200Gb/sec with one UCS.

It shares one user's experience of initial challenges in using DPDK/OVS and improvements over time. Suggestions are made to improve areas like debugging, testing, documentation and training to enhance the usability of DPDK/OVS. Performance tuning techniques like using multiple threads are also briefly covered.
DPDK Integration: A Product's Journey - Roger B. Melton
The document discusses Cisco's experience integrating their data plane product with DPDK. Key observations from implementing DPDK include: adapting multi-threaded applications was difficult in early DPDK versions; UIO eliminates traditional device management; per-core packet buffer caches may be underutilized if RX and TX are on different cores; altering packet buffer pool sizes can impact performance; and PMDs have varying levels of maturity and may not implement all APIs. The solutions involved updating to newer DPDK versions, adapting the application, and being aware of PMD limitations.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

OpenDataPlane - Bill Fischofer
- 1. Presented by Date Bill Fischofer October 2015 OpenDataPlane (ODP) A Quick Introduction and Overview Linaro Networking Group (LNG)
- 2. ● Requirements that motivate and drive ODP ● What is ODP? ● Components ● Structure ● ODP sponsorship and governance model Discussion Topics
- 3. ● Support application portability across diverse ISAs and system architectures ○ Core counts, memory organization, integrated HW capabilities, etc. OpenDataPlane Requirements ● Be able to exploit platform-specific acceleration and offload capabilities (HW and SW) without application effort ○ e.g., HW buffer/packet mgmt, integrated I/O, HW parsing and classification, HW scheduling and flow ordering, HW egress traffic shaping and QoS, etc. ● Support scalability to many-core architectures without application redesign ○ Application design unchanged if running on 4, 40, or 400 cores
- 4. OpenDataPlane Components and Structure An Abstract API Specification Multiple independently maintained implementations of the ODP API Validation Test Suite ODP API Specification ODP Implementations ODP Validation Test Suite
- 5. The ODP API Specification ODP API Specification An Abstract API Specification ● Open Source, open contribution, BSD-3 licensed ● Vendor and platform neutral ● Application-centric--covers functional needs of data plane applications ● Ensures portability by specifying functional behavior of ODP ● Defined jointly and openly by application writers and platform implementers ● Architected to be implementable on a wide range of platforms efficiently ● Sponsored, Governed, and Maintained by Linaro Networking Group (LNG)
- 6. ODP Implementations Multiple independently maintained implementations of the ODP API ● One size does not fit all--widely differing internals among platforms ● Anyone can create an ODP implementation tailored to their platform ● Distribution and maintenance of each implementation as owner wishes ○ Open source or closed source as business needs determine ○ Have independent release cycles and service streams ● Allows HW and SW innovation in how ODP APIs are implemented on each platform ODP Implementations
- 7. ODP Implementations (Cont’d) LNG distributes and maintains a number of Reference Implementations of ODP ● Open source, open contribution, BSD-3 licensed ● Provide easy bootstrapping of ODP onto new platforms ● Implementers free to borrow or tailor code as needed for their platform ● Implementers retain full control over their own implementations whether or not they are derived from a reference implementation ODP Implementations
- 8. ODP Validation Test Suite ODP Validation Test Suite Validation Test Suite ● Synchronized with ODP API Specification level ● Maintained and distributed by LNG ● Open source, open contribution, BSD-3 licensed ● Key to ensuring application portability across all ODP implementations ● Tests that implementations of ODP conform to the specified functional behavior of ODP APIs ● Can be run at any time by both users and vendors to validate implementations of ODP
