Building DataCenter networks with VXLAN BGP-EVPNCisco Canada
The session specifically covers the requirements and approaches for deploying the Underlay, Overlay as well as the inter-Fabric connectivity of Data Center Networks or Fabrics. Within the VXLAN BGP-EVPN based Overlay, we focus on the insights like forwarding and control plane functions which are critical to the simplicity operation of the architecture in achieving scale, small failure domains and consistent configuration. To complete the overlay view on VXLAN BGP-EVPN, we are going to the insides of BGP and its EVPN address-familiy and extend to about how multiple DC Fabric can be interconnected within, either as stretched Fabrics or with true DCI. The session concludes with a brief overview of manageability functions, network orchestration capabilities and multi-tenancy details. This Advanced session is intended for network, design and operation engineers from Enterprises to Service Providers.
2600Hz - Tuning Kazoo to 10,000 Handsets - KazooCon 20152600Hz
People love to talk about scale. Some vendors pitch that their systems easily support 100,000 simultaneous calls, or 500 calls per second, etc. The reality is, in the real world, people’s behaviors vary and the feature sets they use can cut these numbers down quickly. For example, ask that same vendor claiming 100,000 simultaneous calls if it can be done while call recording, call statistics and other features are turned on at the same time, and you’ll usually get a very different, cautious, qualified response.
In this presentation, we'll show you how to set up your infrastructure to support 100,000 simultaneous calls.

Safely Protect PostgreSQL Passwords - Tell Others to SCRAMJonathan Katz
PostgreSQL 10 introduced SCRAM (Salted Challenge Response Authentication Mechanism), introduced in RFC 5802, as a way to securely authenticate passwords. The SCRAM algorithm lets a client and server validate a password without ever sending the password, whether plaintext or a hashed form of it, to each other, using a series of cryptographic methods.
At the end of this talk, you will understand how SCRAM works, how to ensure your PostgreSQL drivers supports it, how to upgrade your passwords to using SCRAM-SHA-256, and why you want to tell other PostgreSQL password mechanisms to SCRAM!
High Scale Relational Storage at Salesforce Built with Apache HBase and Apach...Salesforce Engineering
Apache HBase is an open source, non-relational, distributed datastore modeled after Google’s Bigtable, that runs on top of the Apache Hadoop Distributed Filesystem and provides low-latency random-access storage for HDFS-based compute platforms like Apache Hadoop and Apache Spark. Apache Phoenix is a high performance relational database layer over HBase optimized for low latency applications. This session will explore how the Data Platform and Services group at Salesforce.com supports teams of application developers accustomed to structured relational data access, while surfacing additional advantages of the underlying flexible scale-out datastore.

The advent of Network Function Virtualization (NFV) is dramatically changing the way in which telecommunication networks are designed and operated. Traditional specialized physical appliances are replaced with software modules, called Virtual Network functions(VNFs), running on a virtualization infrastructure made up of general purpose servers. Examples of VNFs categories are NATs (Network Address Translation), firewalls, DPIs (Deep Packet Inspection), IDSs (Intrusion Detection System), load balancers, HTTP proxies. Service Function Chaining (SFC) denotes the process of forwarding packets through the sequence of VNFs. IPv6 Segment Routing (SRv6) is a source routing paradigm that allows to steer packets through an ordered list of VNFs in a simple and scalable manner. In this slides, we present the architecture of SFC using SRv6 for both cases of SRv6-aware and SRv6-unaware VNFs. We provide an open source implementation and easy replicable testbed for the presented work.

Presented at TM Forum Live ! on May 16th 2017
by Red Hat - François Duthilleul Telco Solutions Architect
For the past few decades, telecommunications networks have been built using closed-source monolithic products from network equipment vendors. Today, Network Functions Virtualization (NFV) and Software Defined Networking (SDN) are disrupting the way telecommunications networks are being built and operated and are gradually becoming the foundation of modern networking. The introduction of virtualisation, automation and orchestration provides the basis from which the networks will evolve towards a Zero-touch Orchestration, Operations and Management (ZOOM) target.
This presentation highlights the prominent role of open source and Red Hat’s portfolio in the implementation of future networks.

LAS16-405: OpenDataPlane: Software Defined Dataplane leader
Speakers: François-Frédéric Ozog
Date: September 29, 2016
★ Session Description ★
You may think OpenDataPlane and DPDK are somewhat equivalent. But they are not. OpenDataPlane is about Software Defined Dataplanes while DPDK is a Software Dataplane. A Software Defined Dataplane can control a hardware only Dataplane in a way that packets can go from input port to output port without reaching a CPU core. With Software Dataplanes , all packets have to reach a CPU core. As a result, one vendor could leverage a Software Defined Dataplane to build a 100Tbps network box while it is not possible with a Software Dataplane.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

3. A bit of background

4. Our’s vision
A communications product you can use as cloud-based, on-premises
or any combination of local/remote sites and cloud
providers.
The only operator’s interface for voice/data/video is the browser. The
web application connects to any local cluster if available, or directly
to the cloud if none is up.
Self-healing, peace of mind, dev-ops friendly. If a node goes down
in any of the local clusters, there is no hurry in repairing it. Even if the
full cluster goes down, operators connect automatically to another
one or directly to the cloud.
The specific client application should be developed easily, in a few
months, without special distributed programming abilities.

11. Freeswitch was not enough
We need SIP
OpenSIPS, Kamailio, Mobicents…
… they don’t really fit.
11
12. Another SIP product?
Existing products are either too complex to integrate into a
distributed application server (Kamailio, Mobicents) or too
high-level to fully use all SIP’s potential (Freeswitch, Asterisk).
SIP is a very complex protocol, but most of this complexity
has no added-value and should be hidden from the
developer. On the other hand, SIP concepts are actually easy.
No product clearly maps SIP concepts to the application.
Implementing new RFCs is currently a painful process.
SIP routing is at the very heart of any multimedia solution.
Wouldn’t it be nice to have full control of it?
12
13. NkSIP’s vision
An open source tool to develop any kind of SIP
application (NkAPPs), specially focused on highly
available, distributed and scalable SIP applications.
Each NkAPP application decides what callback functions
to implement. Very few for a simple, standard behavior.
Many of them for fine-tuned or low level behaviors.
NkSIP takes care of all the details: retransmissions,
transactions, authentication, dialogs, sessions, etc.
All SIP applications are similar from NkSIP’s point of
view: UACs, UASs, proxy servers, B2BUAs, SBCs, load
testers… why a different box for each one?
13
14. NkSIP’s vision
NkSIP does NOT try to emulate a PBX. No dial plans. No
extensions. Only pure SIP. You need to now what INVITE and BYE
means to use NkSIP, but don't need a deep understanding of the
details.
Implementing new RFCs should be easy and natural. NkSIP offers
a rock solid core, written from scratch core to develop distributed,
highly available and scalable systems. It has a hierarchical plug-in
system to develop new functionality without having to modify the
core or other base plugins.
The Erlang ecosystem is the perfect fit for this kind of product. You
can run any number of SIP applications on a NkSIP cluster, using
Erlang but (soon) also using Javascript, Lua, Java, or any other
language capable of receiving a JSON over a socket connection.
14
15. Current features
Full support for all defined SIP methods: PRACK, INFO,
UPDATE, SUBSCRIBE, NOTIFY, REFER, PUBLISH and
MESSAGE, as UAC, UAS and Proxy.
Registrar and Event State Compositor (using the RAM built-in
store or any other external database).
Stateful proxy servers with serial and parallel forking. Stateless
proxy servers, even using TCP/TLS.
IPv6 support. NkSIP can connect IPv4-only with IPv6-only hosts.
Support for NAPTR and SRV location, including priority and
weights.
Support for events, reliable provisional responses (100rel),
session timers, path, service route, outbound and GRUU.
15
16. Current features
Automatic outbound registrations and timed pings.
Dialog and SDP media start and stop detection. SDP
processing utilities.
UDP, TCP, TLS, SCTP and WEBSOCKETS transports, capable
of handling thousands of simultaneous sessions.
Robust and highly scalable, using all available processor cores.
Currently is able to process 10.000 registrations/sec or 4.000
call setups/sec (INVITE+ACK+BYE) on a 4-core i7 machine.
A written from scratch, fully typed Erlang code easy to
understand and extend. Unit tests cover nearly all of the
functionality. Few external dependencies.
Hot, on the fly core and application code upgrade.

19. Plugin system
Most complex functionality have been extracted
into plugins: Registrar, PRACK, Outbound, etc.
Rich set of callbacks available.
The core remains simple.
Each plugin adds API functions and callbacks for
your application (and other, higher level plugins).
Each NkAPP can implement a different set of
plugins. Can even change them on the fly.
Zero added latency, even with many plugins.

20. Pending features
Distribution based on the Dynamo
model.
Other languages for NkAPPs (Node.js,
Lua, Python…)
More RFCs and Event Packages
IMS

28. Another application server?
NkSIP offers a fresh approach to the development of
applications, and it has very powerful tools, but is focused on SIP.
However, NkSIP could behave as a generic high-capacity, low-latency
message processing engine.
Many concepts and technology solutions from NkSIP are
applicable to many other protocols: REST, Diameter, MSRP,
XMPP, DNS, DHCP, Mail, OpenFlow…
There is no easy to use, fully distributed, heavy-load open source
application server out there.
This looks a lot like an SDN/NFV framework!

29. NkCORE’s vision
You start any number of control nodes, and install any number of user
applications (NkAPPs) on the cluster.
Incoming messages (in a broad sense: SIP, REST request…) are sent to a
specific control node and triggers the call of specific application callbacks.
Applications are written using Javascript, Lua, Java, etc.
Many modules are available, offering tools and semi automatic processing of
messages: SIP (NkSIP), Web (NkREST), DNS, DHCP, Diameter,
OpenFlow,etc. Each one adds new callbacks and APIs available to the
application. Some of them offer additional optional plugins (i.e. event
support packages for SIP).
Many common functionality is available: configuration, cluster management,
distributed database, network transport management, storage, dns, logging,
authentication, roles, etc.

30. NkCORE’s vision
You also start any number of worker nodes. They don’t need to have Erlang, only Docker.
The NkAPP can program the scheduling of tasks (i.e, 10 instances of Freeswitch, 5 instances of
a node.js application, etc.), and NkCORE selects the worker nodes and downloads and starts
and monitors the Docker processes in selected ones.
Control nodes route specific traffic to any of the workers nodes, and offers network
functionalities to the application: firewall, load balancer, VPNs, VLANs… (using Openvswitch).
NkCORE offers easy-to-use APIs for each type of task, and can act as a proxy or B2BUA,
transparent or not. The application doesn’t even need to know that it is speaking to several
different instances of the processes.
We plan to support many common used packages:
Media servers (Asterisk, Freeswitch…) and XMPP (Ejabberd…)
NoSQL (Redis, Riak, CouchDB…) and SQL databases (MySQL, PostgreSQL)
Distributed Storage (Ceph)
Mail Servers
…

33. Expected features
The applications are in full control not only of the business
logic, but also of the network, the storage and the related
processes (data bases, media servers…)
Hot code loading (NkCORE itself, modules and user
applications). Hot relocation of external processes.
NkCORE offers a everything-as-a-service model to the
applications (Freeswitch, DNS, Riak, …), even in local. Hybrid
or hierarchical cloud model. Multi-cluster management.
Allows applications to become highly available and scalable
very easily.
