Tech Talk by John Casey (CTO) CPLANE_NETWORKS : High Performance OpenStack Ne...nvirters
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

13. DEFINITIONS
Fundamental network architectures have been impacted by the
introduction and growth of virtual machine environments.
Often these terms are used interchangeably
Network Virtualization
Virtualized Networks
Network Abstraction
Software Defined Networking
15. NETWORK VIRTUALIZATION
Network Virtualization can be defined as using network resources through a
logical segmentation of a single physical network
• VLANs – Virtual Local Area Networks
• VRF – Virtual Routing and Forwarding
• MPLS – Multi-protocol Label Switching
• VPN – Virtual Private Networks
• MEC - Multi-Chassis EtherChannels
• VDC - Virtual Device Contexts
• VSANs – Virtual Storage Area Networks
17. VIRTUALIZED NETWORK SWITCHES
Server virtualization has led to the development of Virtual switches within the
hypervisors.
Allows for communication between virtual machines, and between virtual machines
and the physical network
• VMware - vSwitch
• VMware – Distributed Virtual Switch (DVS)
• Cisco Nexus 1000v
• Citrix Distributed Virtual Switch (Openswitch)
• KVM – Linux bridging, Open virtual switch

21. NETWORK ABSTRACTION
Traditional network constructs were not designed or intended
to support dynamic workloads in highly virtualized or cloud
environments
Overlay technologies allow for independent logical networks
(Overlay Networks)to be built on top of existing IP
infrastructure (Underlay Network)
Abstraction presents the logical networks as a simplified view
22. NETWORK ABSTRACTION
Generic Router Encapsulation (GRE)
Stateless Transport Tunneling (STT)
Overlay Transport Virtualization, (OTV)
Locator ID Separation Protocol (LISP)
Network Virtualization using GRE (NvGRE)
Virtual Extensible LAN (VxLAN)
23. Overlay Networks and Encapsulation
• Overlay Networking is achieved by using
encapsulation of the original network frame in a IP
packet.
• In the Data Center, VxLAN is a new overlay protocol
specifically designed to allow the creation of more
flexible and extensible virtual networks on top of a
hardware underlay.
24. Underlay Network
IP Subnet A IP Subnet B
IP Subnet D
IP Subnet C
This is an example of a
Layer 3 IP routed
network in a Data
Center
The physical network is the
underlay network and uses
“traditional” network protocols
OSPF
Network Segments are isolated
by Layer 3

31. SDN and Controllers
• A Controller in a SDN is the “brains” of the network.
• It relays information to the switches/routers ‘below’ (via southbound APIs)
• and the applications and business logic ‘above’ (via northbound APIs).
• Example:
• For VMware, the controller is called the NSX Controller. It resides as software on a
virtual machine within the vSphere environment.
• For Cisco, APIC (Application Policy Infrastructure Controller) is the controller and resides
as software on “bare-metal” compute platforms
33. Today’s Networks are Defined by the “Box”
• Hardware, Operating System, and Applications
built into a single hardware device
• Separate Policies
• Distributed algorithms between devices
• Federated Systems
• Derived from ARPANET
So let’s reset…..
34. • Networks today are rooted in packet switching concepts developed during 1960
to 1970’s.
• Core functions
• Packet switching
• Path selection
• Configuration / Management
• Services
• Path selection, the control plane,
is distributed on each network element.
• Distributed control planes eliminates single points
of failure disrupting the entire network.

35. What is SDN?
• “Early” view
• The control and the data planes are decoupled, network
intelligence and state are logically centralized, and the
underlying network infrastructure is abstracted from the
applications
• Single control plane manages multiple network devices
• Singular Southbound protocol
• Common Northbound protocols
36. • Early view of SDN has two characteristics (*)
• Control plane is separated from
device implementing data plane,
• Single control plane manages
multiple network devices
• SDN / OpenFlow initial deployments
were network research at universities
(Stanford ) providing a cost effective
and ‘clean slate’ network architectures.
• SDN is a tool to enable a higher degree of
control over network devices.

37. What is SDN?
• “Current” view
• The control and the data planes can be decoupled, or the local
control plane can be overridden.
• The underlying network infrastructure is abstracted from the
applications
• Hybrid/Multiple control planes manage multiple network devices
• Multiple Southbound protocol
• Common Northbound protocols
• Inclusion of Overlay Networks

40. Floodlight and Open Daylight
The Floodlight Open SDN Controller is an
enterprise-class, Apache-licensed, Java-based
OpenFlow Controller. It is supported by a
community of developers
The Open Daylight controller maintains the flexibility
to deploy SDN, yet still mitigates many of the risks of
adopting early stage technologies and integrating
with existing infrastructure investments.
42. Northbound Protocols
• REST (web based) API – applications which run on different machine or address
space on the controller
• HTTP PUT, GET, POST, DELETE
• URL
• Body
• Authentication
• Content Type (XML or JSON)
• Web Browser
• http://<controller ip>:8080/……
• OSGi framework is used for applications that will run in the same address space as
the controller.
43. Southbound Protocols
• Southbound protocols provide a communications path between the controller and network
device.
• OpenFlow used by the purist SDN approach.
• One design goal of the controller is to enable abstraction
of the network elements.
• For this reason, any number of southbound may be
implemented by the controller.
• Examples:
• OpenFlow
• Cisco onePK API
• SSH | CLI | HTTP |SNMP
• XMPP
• Interface to the Routing System Project (I2RS)
• Open vSwitch Database Management Protocol (OVSDB)

44. Network Functions Virtualization
• Network Functions Virtualization (NFV) is a network architecture concept
that proposes virtualization of entire classes of network node functions
into building blocks that may be connected, or chained, together to create
communication services.
• SDN is focused on the separation of the network control layer from its
forwarding layer
• NFV is focused on porting network functions to virtual environments in
order to enable the migration from proprietary appliance based
deployments to a standard hardware and cloud based infrastructure.
• SDN is related to NFV, but they refer to different domains.
• Both concepts can be complementary, although they can exist
independently.
45. SDN Key Players / Startups

47. Software-Defined Networking Use Cases
“Would you tell me, please, which way
I ought to go from here?“
"That depends a good deal on where
you want to get to.“
"I don't much care where –“
"Then it doesn't matter which way you
go.”
― Lewis Carroll, Alice in Wonderland
(from The 2013 Guide to Network Virtualization and SDN)
The Cheshire Cat
Software-Defined Networking is a tool that only provides business relevance when a
function can be done cheaper, better or faster than using traditional networking hardware
and software.
