Fix VxLAN issue in SFC integration by using Eth+NSH and VxLAN-gpe+NSH Hybrid Mode - Yi Yang
NSH (https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/) is a standard IETF is drafting, it is especially introduced to address SFC (Service Function Chaining) in SDN/NFV, VxLAN-gpe is a proposed encapsulation protocol, but in data center, SFF (Service Function Forwarder) and Classifier are on the same ovs node, VxLAN-gpe can’t handle such cases, https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/ also suggested another encapsulation type Eth+NSH+overload, which can reduce unnecessary encapsulation & decapsulation and significantly improve performance. My presentation will show all the details about how NSH and SFC work together in data center and demo it by using Eth+NSH and VxLAN-gpe+NSH hybrid mode, this demo will use the almost same network topology setup as OVSDB+SFC+Openstack+tacker integration used except VM isn’t be started by Openstack and it is a docker container, this demo also shows typical Openflow multi-writer issue and indicates why we need a solution to Openflow mulit-writer issue.

NFV/SDN Information and Data Models in Standards and Open Source - Bryan Sullivan, AT&T
Information / Data Models will play a key role in establishing a model-driven NFV service environment. Since realization of NFV-enabling platforms is substantially driven by Open Source communities today, SDOs and Open Source communities should seek alignment on the models that are or will be implemented in Open Source. This effort requires establishing a baseline for the current state of alignment, processes and tools for assessing models, and collaborative engagement of SDOs and Open Source to promote alignment. This talk will summarize the current state of standardized models, as well as the current defacto models derived from Open Source. A demonstration will be provided for the tools and processes used in this effort. The talk will finish with a draft summary of the findings so far on key gaps between standardized and Open Source models, and plans to address them.

A Whirlwind Tour of OpenDaylight - Colin Dixon, ODP & Luis Gomez, Brocade
OpenDaylight is a broad, industry-wide effort to build a common platform for SDN and NFV solutions. It currently has more than 50 subprojects providing support for everything ranging from southbound protocols like OpenFlow and NETCONF to high-level features like network virtualization or policy-based network configuration. Keeping track of these projects, what they provide, and how they interact is a difficult task even for people deeply involved in OpenDaylight. However, this understanding is critical, for newcomers trying to learn how they can use OpenDaylight and/or where they might contribute. In this talk, Luis Gomez and Colin Dixon will lend their experience from running the TSC and Integration project, respectively, to provide an introduction to all of the current projects in OpenDaylight, what they do, how they interact, and why people should care about them.

Intent-based VPNs and Its Future in SDN - Icaro Camelo, Inocybe Technologies
The new SDN era is more abstract, orchestrated, independent and doesn't rely on specific technologies. That being
said, Intent frameworks manage and direct network services and resources based on describing the “Intent” for network behaviors and policies. We will discuss how an Intent-based solution can abstract different types of technologies (such as MPLS, BGP, GRE, etc) and what are the architecture challenges of this process.

Securing SDN Controllers – Attack Surfaces and Mitigation Strategies - Rafat Jahan & Vedyas Krishnamoorthy, Tata Consultancy Services
SDN controller is identified as the single most important point of failure that can affect the entire network, hence securing the controller from external sources of attack is of importance. The attack could be from the application, network or the peer controllers. The rationale behind a unified controller security plugin is to devise a security information repository for the applications and is developed for SDN controllers as an infrastructure that provides a single pane of visibility related to controller security. The security information could be for collating source of different attacks reported in SB plugins/suspected controller intrusions or information about trusted controllers in the network. It also opens the possibility of mitigating persistent attack(s)on the controller by blocking(quarantining)the offending switches/ports or locking them down temporarily/permanently.

Implementation of an SSL Proxy in a SDN to Monitor Internet Users Aboard A Navy Ship - Patrick Dyroff, Hanover High
Cyber Security is essential aboard US Naval ships. With a variety of people taking part in the ship’s network, browsing the web or otherwise, measures must be taken to ensure oversight of each user. The problem is that with the conventional network used today, a network administrator or information technology professional cannot know how many devices are aboard the ship and connected, much less their activity on the network. The solution I used was the implementation of a SSL Proxy in a new network paradigm known as Software Defined Networking (SDN). An SDN simplifies routers, switches and other network devices by adding a centralized controller which allows full visibility of every device on the network, dynamic programmability of traffic flows and full control.

Safeguarding Vulnerable, Exposed Internet WAN Connected Equipment - Thomas Kee, Tempered Networks
SDN innovations are making migration from highly secured VPN networks to the Internet WAN a reality. Connecting trusted devices and subscribers to a trusted network formerly achieved with complicated equipment and expensive advanced networking services, is now greatly simplified with cutting edge security methods and products that provide robust solutions with military grade encryption, identity assurances, and VPLS network segmentation.

SDN appliances can be quickly and seamlessly deployed, turning vulnerable IP-enabled devices that cannot protect themselves into hardened, invisible assets. Cloaking technologies minimize potential network attack surfaces, significantly reducing vulnerability to externally mounted attacks. With added intelligent control plane management APIs, developers can quickly deploy flexible network customizations, simplifying IT network management.

Open-O (Orchestrator) Implementation for Fixed and Mobile NFV Networks - Michael Kearns, Huawei; Lingli Deng & Hui Deng China Mobile
OpenO is designed to be ETSI NFV architecture compliant, whose northbound interface supports both TOSCA and YANG templates input as well as an GUI engine for NFV service template creation/editing. OpenO is composed of a NS orchestrator, responsible for NS lifecycle events management, and Resource orchestrator, maintaining a DB for stats and status of resource/VNF/NS instances. There is also a dedicated module for real time monitory on the running status of instantiated VNFs/NSs. Currently, Tacker is integrated as the generic VNFM implementation, which could be used to create and manage the corresponding virtual resources via OpenStack, e.g. virtual machines via Nova and virtual networks via Neutron. Service Function Chaining is also supported by integrated SDN driver within the NS orchestrator talking to an ODL controller to fulfill network orchestration.

Power-up Networking for Micro-Services: Connecting your application containers with SDN - Jason Messer, Microsoft
SDN can be your unfair advantage when dealing with micro-services from DevOps. It is the ultimate infrastructure-as-code experience – let the developers set their own pace, and still maintain control and reliability for enterprise class infrastructure services. Designing and deploying networks for new micro-service based architectures can be just as fast as the development cycle, if you have the right infrastructure support. We know how to use SDN to solve the challenges of agility, flexibility, scale, availability, and security for VMs in the software-defined data center. But, have you thought about how it could help you cope with a 10 to 100x increase in the number of network endpoints, while maintaining security? In this session we’ll talk about some of the amazing results you’ll be able to get when you combine SDN and a container based development practice.

Scalable and High-Performance Virtual Switch Using Pre-vSwitches - Jun Nakajima & Mesut Ergin, Intel
A single and centralized vSwitch (virtual switch), such as OVS (Open vSwitch) can have scalability issues, thus performance issues as it needs to perform low-latency packet processing among the data plane VNFs (Virtual Network Function) running in VMs (virtual machine).

We have been working on inter-VM communication to achieve low-latency and high-throughput at OPNFV. In our prototype based on KVM, the “pre-vSwitch” of the source VM can directly access the destination VM or the shared pages in a protected and efficient fashion. By having a small cache of the information maintained by the vSwitch, the pre-vSwitch can send packets in consistent with the vSwitch. That way we can offload the vSwitch for inter-VM communication, and thus we can improve scalability and performance of the vSwitch. We share our findings and performance data, showing a prototype that uses OVS with DPDK.

Container Network Interface: Network Plugins for rkt, Kubernetes and Beyond - Josh Wood, CoreOS
With the rise of containers comes new networking problems to solve. Numerous container SDN solutions have entered the market, each best suited for a particular environment. Combined with multiple container runtimes and orchestrators available today, there exists a need for a common layer to allow interoperability between them and the network solutions.

As different environments demand different networking solutions, multiple vendors and viewpoints look to a specification to help guide interoperability. Container Network Interface (CNI) is a specification started by CoreOS with the input from the wider open source community aimed to make network plugins interoperable between container execution engines. It aims to be as common and vendor-neutral as possible to support a wide variety of networking options. Today it is adopted by Kubernetes and rkt.

Towards Continuous Delivery in Open Source Projects - Daniel Farrell, Red Hat
In a world of ubiquitous Continuous Integration testing, Continuous Delivery is becoming a requirement for modern open source projects. Integration-focused projects like OPNFV can only validate consumed upstream projects as frequently as they provide testable release artifacts. As integration tests become more frequent (towards Continuous Integration), the frequency of the integrated projects’ releases must increase (towards Continuous Delivery).

The release artifacts expected from modern open source projects are also becoming increasingly complex. Vagrant boxes and Docker containers need to be built alongside traditional packages. Configuration management options like Ansible and Puppet need to be provided.

These topics and others, from the trenches of building OpenDaylight’s delivery pipeline.

Path Protection and Failover Strategies in SDN Networks - Rashmi Pujar, Inocybe Technologies
In a SDN solution it is crucial to have a self healing network that detects node and link failure events to recover the connectivity of a system by exploiting redundant links; all of which is transparent to the user.
Failover mechanisms can be implemented either using slow-reroute or hard-reroute.
1. Slow-reroute is done in software using disjoint path calculation algorithms (E.g. Suurballe algorithm) and standard Openflow features.
2. Fast-reroute is done using hardware assisted OAM with 802.1ag path failure detection and using Openflow group failover table features.
Opendaylight controller currently implements path failure detection and recovery using slow-reroute mechanism. In this presentation we discuss the current implementation of failover mechanisms, and the challenges in supporting it in the SDN paradigm.
