The History of Data Push and the Lightstreamer Technology
Agenda:
- History of Data Push
- Lightstreamer Technology
- Lightstreamer Success Stories
- MQTT.Cool and JMS Extender
This document provides an overview of the MQTT protocol. Some key points:
- MQTT is a popular protocol for IoT devices to publish and subscribe to data. It is open, simple to implement, lightweight, and robust.
- An MQTT server (broker) receives all messages and manages client connections and message delivery. It can handle thousands of clients simultaneously depending on capacity.
- Devices connect to brokers to publish data to topics and subscribe to topics to receive data. Brokers can be bridged to expand reach.
- Features like quality of service levels, retained messages, and last will messages provide reliability and notification capabilities.
The document provides an overview of a training on practical demonstrations of digital forensic tools. It introduces the instructor and their qualifications. The agenda includes an introduction to digital forensics, computer forensic processes, and demonstrations of forensic tools like FTK Imager and EnCase. Key points covered are the forensic investigation process of acquiring, analyzing, and reporting evidence from a computer, and types of data like active, latent, and archival that can be extracted.
Computer networks play an important role today, but it is essential to check if computers are ready for data transfer by determining if they are connected to the network. Network monitoring collects information from various parts of the network to manage and control it. It has three main goals: performance monitoring, fault monitoring, and account monitoring. Tools like ping and trace route are used to check connectivity and network performance.
This document provides instructions for configuring and using PRTG Network Monitor to monitor the LICT network. It describes setting up the PRTG server, adding administrator credentials, configuring monitoring of network devices, servers, websites and cloud services. It also outlines how to set up groups, devices and sensors to monitor key aspects of the LICT network like domain controllers, Exchange servers, switches and service servers. The document concludes with information on generating and customizing reports in PRTG to analyze monitoring data and system performance.
For enterprise software applications and related processes, highly accurate and synchronized time is a necessity. An inaccurate
computer clock can cause significant problems. A discrepancy of a minute or two could cause a significant and unacceptable margin of error, since many applications require that the time be kept accurate to the nearest second or less.
The document discusses network time servers and synchronization. It describes how most electronic clocks in devices are inaccurate and drift over time, causing issues for file systems, billing, security, and more. It recommends using a dedicated time server running NTP behind a firewall to provide the most accurate and secure synchronization for a local network. It also discusses Meinberg as a leading manufacturer of NTP servers and their LANTIME M1000 time and frequency synchronization platform.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

2. Agenda
● History of Data Push
● Lightstreamer Technology
● Lightstreamer Success Stories
● MQTT.Cool and JMS Extender
3. What Is Data Push?
Information is delivered on the fly as soon as it
is generated. Web pages and mobile apps are
updated in real time.
Many application domains are taking benefit from push technology:
● Financial Services: Online trading platforms for capital markets, live price
dissemination, order submission, spread betting
● Gaming: Sports betting, online casinos, online multiplayer video games
● Aerospace and Defense: Web telemetry of space vehicles, satellites, and
aircrafts, web-based management of airport operations
● Media: social TV, second screen, sports event live data
● Transportation and Logistics: live tracking, supply chain monitoring
● Alerting: Emergency mass notification systems
● And many others: Social networks, in-app notifications, online
collaboration tools, online auctions, systems monitoring, e-learning, etc.

5. The Four Waves
of Data Push
● 1996-2000: Webcasting
Coarse-grained daily updates
● 2000-2012: Comet
(the term "Comet" was coined by Alex Russell in 2006, but Comet technologies existed since 2000)
Polling, long polling, streaming
● 2009 onwards: Push Notifications
Apple APNs, Google FCM (previously C2DM and GCM), Web
Push protocol
● 2012 onwards: WebSockets
Full-duplex bidirectional streaming
6. Second Wave:
the Raise of Data Push
● 2000: Online financial trading systems required
data push for real-time stock price delivery
● Requirements:
○ Fine-grained updates
○ Real-time updates (low latency)
● Very first players: Lightstreamer, Caplin,
Pushlets, KnowNow
● Technology:
○ Front-end: HTML and/or Java applets
○ Transport techniques: Ajax polling, Comet long
polling, and Comet streaming
7. An Example to Help Illustrate
A temperature and
humidity sensor must send
data to a Web browser
(sensor example).
Let's see how this might
have been done in the
history of push technology.
Web
9. Full Page Refresh
Typical issues:
● Low update frequency; no
real time
● High bandwidth usage
● High load on Web server
Sensor example: for each
refresh, the full HTML page
with the current values is
retrieved
wait...
wait...
wait...
Refresh 1
Browser Server
wait...
Refresh 2
User
wait...
Refresh 3
wait...
10. Ajax Polling
Typical issues:
● Low update frequency; no
real time
● High bandwidth usage (but
lower than page refresh)
● High load on Web server
Advantages:
● User interface is never
blocked
Sensor example: for each
poll, the current values are
retrieved
wait...
wait...Action 1
Browser Server
Action 2
User
wait...
11. Comet Long Polling
(or HTTP Long Polling)
Typical issues:
● Medium update frequency;
near real time
● Medium bandwidth usage
(HTTP headers still present
in each round-trip cycle)
● High load on Web server
Advantages:
● User interface is never
blocked
● Low latency on
low-frequency events
Action 1
Server
Action 2
User
wait...
wait...
wait...
Browser
12. Sensor example: for each
poll, the new values are
retrieved only when they
become available. Otherwise,
the request is kept pending
(long poll)
Action 1
Server
Action 2
User
wait...
wait...
wait...
Browser
Comet Long Polling
(or HTTP Long Polling)
13. Comet Streaming
(or HTTP Streaming)
Typical issues:
● May be blocked by some
anti-virus software
mounted on proxy servers
Advantages:
● High update frequency;
low latency; true real time
● Low bandwidth usage
(very little overhead)
● Low load on the network
infrastructure
Action 1
Server
Action 2
User Browser
14. Action 1
Server
Action 2
User Browser
Possible techniques:
● Iframe streaming
● XHR streaming
● Flash streaming
● Server-Sent Events (SSE)
Sensor example: the server
keeps pushing real-time
updates as they become
available, whatever is the
frequency, without
request/response round trips
from the client
Comet Streaming
(or HTTP Streaming)
15. Third Wave:
WebSockets
● Goal:
○ Full-duplex asynchronous communication between a
web client and a web server
● Why not just plain TCP?
○ Client runs untrusted code: origin-based security
model; ports 80/443
○ WebSockets are message oriented (onmessage, send),
TCP is stream oriented
○ WS split messages into frames, to allow:
■ Sending messages of unknown size without buffering
■ Multiplexing more logical channels on the same connection
■ Masking (XOR with random key) frames sent from the client to
prevent cache poisoning on flawed proxy servers
16. WebSockets
Typical issues:
● There might be some
firewall or proxy still
blocking WebSockets
Advantages:
● Same as HTTP Streaming
Action 1
Server
Action 2
User Browser
Sensor example: it's a
unidirectional scenario (from
server to client), so with
WebSockets the behavior is the
same as with HTTP Streaming.
17. WebSockets vs. HTTP/1.1
Myth:
WebSockets are better than HTTP for sending data from the server to
the client (use less bandwidth, have lower latency, etc.)
Myth debunked:
When sending data from the server to the client, WebSockets and
HTTP Streaming behave exactly the same way.
After handshake, pure payload over TCP is streamed in both cases
(WebSocket framing and HTTP chunking have a negligible difference)
18. ServerBrowser
The real difference is for bidirectional scenarios:
ServerBrowser ServerBrowser
TCP connection 1 TCP connection 1 TCP connection 2
WebSocket
HTTP
1. HTTP requires at least 2 sockets
2. HTTP requires full round trip for each request
(by default there is no pipelining)
3. HTTP gives no control over connection reuse
(risk of a full SSL handshake for each request)
4. HTTP gives no control over message ordering
WebSockets vs. HTTP/1.1
19. What About HTTP/2 ?
HTTP/2 improves performance over HTTP/1.1:
● Pipelining of requests
● Multiplexing of requests
● Compression of headers
● HTTP/2 server push
What is HTTP/2 server push?
● It is not a notification mechanism
● It can send page resources without waiting for requests
● It does not replace WebSockets
● It is possible to combine Server-Sent Events (SSE) and
Multiplexing to "emulate" WebSockets (with no
particular benefits)
20. In-app Notifications vs.
Push Notifications
In-app Notifications (Data Streaming):
● Server sends real-time data directly to the app
● The app needs to be running to receive the data
● High throughput
● Low latency
● Guaranteed delivery
Push Notifications:
● Server sends notifications to Google/Apple servers
● Google/Apple servers send notifications to the device
● The app does not need to be running to get the data
● Low throughput
● No control over latency and actual delivery
22. What Is Lightstreamer?

28. ● Efficient and reliable bidirectional channel provided in
all the cases (whatever is the underlying transport)
● Messages sent from the client to the server have
in-order guaranteed delivery with automatic batching
● Lightstreamer enriches HTTP:
○ Messages are acknowledged explicitly
○ Lost messages are retransmitted automatically
○ Out-of-order messages are reordered automatically
○ Underlying socket is kept open for reuse via reverse heartbeats
○ Multiple requests are automatically batched, to highly reduce the
number of HTTP round trips
Multichannel Transport:
Bidirectional Channel

29. ● Data can be delivered to mobile clients using native
push notifications too
● Apple APNs and Google FCM are supported
● If an app is not active, the device will receive live
updates in any case
● No extra development on the server side: messages
originated from the Data Adapter can use both the
streaming channel and the push notification channel
● Trigger support: determine what messages should
result in a push notification

● Asymmetric pub-sub:
○ In many scenarios the "data feed" is completely different from the
data consumer (topology, protocol, business model)
○ Optimization for massive publishing from server-side data feeds
● Clients can still publish:
○ The Client (Subscriber API) can send messages to the Adapter to be
processed and possibly incorporated into the data stream

35. Optimized Delivery:
Filterability
● Data filterability
○ Based on the nature of the data, series of updates
to an item can be filtered, to reduce frequency, via:
■ Queueing
■ Resampling
■ Conflation
● Lightstreamer's filtering
○ For each subscription of each client, Lightstreamer
allows to define how data can be filtered, with
several parameters
○ Filtering is then applied on the fly to the data
stream based on a number of static and dynamic
conditions
36. Optimized Delivery:
Throttling
● Bandwidth Control
○ For each client, a maximum bandwidth can be
allocated to the multiplexed stream connection
● Frequency Control
○ For each subscription of each client, a maximum
update frequency can be allocated
● Smart Throttling
○ Internet congestion is detected
Lightstreamer heuristically combines these
three variables to dynamically throttle the data
flow with filtering See live Bandwidth and Frequency Demo:
https://demos.lightstreamer.com/BandwidthDemo/
37. Optimized Delivery:
Other Mechanisms
● Batching and TCP packet optimization:
○ Data is aggregated efficiently within TCP packets
○ Configurable trade-off between latency and overhead
reduction, overriding Nagle's algorithm
● Lightweight protocol:
○ Position-based protocol with negligible overhead (no JSON, no
XML, no metadata redundancy)
● Delta delivery:
○ For subsequent updates to an item, only the actually changed
fields (delta) are sent; custom selectors available
● Multiple subscription modes:
○ MERGE, COMMAND, DISTINCT, RAW

47. Lightstreamer Named a
"Cool Vendor" by Gartner
Gartner, "Cool Vendors in Application
and Integration Platforms, 2012", by
Massimo Pezzini and Jess Thompson,
11 April 2012.
Cool Vendor Report 2012 cites Weswit (former name of Lightstreamer
company), with its Lightstreamer product, as innovative, impactful and
intriguing in the area of Application and Integration Platforms.
"Web streaming is an emerging form of MOM aimed at enabling back-end applications to send real-time
messages over the public Internet, typically to large numbers (up to millions) of mobile or stationary
endpoints, according to a publish-and-subscribe model". When analyzing 'Who should care' the report goes
on to explain: "ISVs, SIs and cloud service providers that require efficient, low-latency and scalable
publish-and-subscribe data distribution to mobile and Web-based endpoints should look at Web-streaming
technologies as a way to add value to their offerings by enabling reliable and relatively easy-to implement
connectivity."
