[5] Bandwidth Comparison Latency comparison [5] This shows significant difference for both bandwidth consumption & latency which shows that the Lightstreamer scales better than simple socket IO. Lightstreamer Architecture The Lightstreamer engine implements publisher subscriber model. Lightstreamer uses the long-polling technique It basically has three components [7] 1. Server side implementation-coded in java(Lightstreamer server) 2. Client side implementation coded in javascript 3. Adapters to support diversity of data exchange platforms Server The server consists of java process. This process controls the Network messaging stack & threads which helps the process to achieve maximum optimization for the returning the data. The servers use java NIO framework to scale up with huge number of connections It uses advanced techniques which allow data transfer without being blocked by the firewall The server continuously pushes the data to client (streaming) which is then displayed in UI by client Client The client side uses the API provided by the Lightstreamer vendors which allows the clients to update the contents of HTML & HTML 5 web pages in real time. The javascript use helps achieve the compatibility with any browser, both desktop and mobile .There is no need of third party plugins to be installed which is a big advantage Adapters As shown in the below diagram we have Two sets of adapters in the architecture While creating a new lightstreamer session, the client can select the adapter to use. Each lightstreamer session needs the adapter set which includes one metadata adapter & multiple data adapters. These adapters are customized components which reside on server. These adap... ... middle of paper ... ... Lightstreamer framework is useful for real time data updates for applications like chat rooms, blogs, notifications, Web site live data updates etc. • Monitoring and telemetry:NASA Is Using Lightstreamer to dispatch the real time data coming from the satellites • Telecommunication & media: Lightstreamer is the best solution for providing live feeds for sporting events • Transport system monitoring & updates • Web Mail system • Public utility services Conclusion Lightstreamer provides a framework for push technology implementation in which real time data updates & exchange is achieved with low delays & high scalability. It’s an emerging form of Message oriented middleware which allows applications to send real time messages over internet & is firewall friendly which is gaining popularity in industry especially in domains which require real time web experience.
In this lab, we used Transmission Control Protocol (TCP) which is a connection oriented protocol, to demonstrate congestion control algorithms. As the name itself describes, these algorithms are used to avoid network congestion. The algorithms were implemented in three different scenarios i.e. No Drop Scenario, Drop_Fast Scenario and Drop_NoFast Scenario.
I work in the event technology field and have been responsible for managing the setup and operation of sound, visual, lighting and tele-communications technology for events. Success requires the synchronization of disparate technologies and following a timeline of events that may require on the fly reevaluation and modification. Inevitably technology will fail, either through its own internal fault or in the connections between devices, by electrical/internet problems and/or when media compatibility/playback issues fail or do not perform as
It is also written in pure JAVA and can be used as a standalone library or client
1.4 – State why and when health and safety control equipment, identified by the principles of protection, should be used relating to types, purpose and limitations of each type, the work situation, occupational use and the general work environment, in relation to:
This also provided the ability to handle large volumes of client requests without creating unwanted delays, thus, low latency and high availability were achieved. Network load balancer provided a continuous service by automatically detecting any failures of a server and redirecting client traffic among the remaining servers. Scalability was another reason to use a server cluster. As traffic increases, additional servers can be added to the cluster if needed to handle the extra
Dementia is a long-term condition that normally affects people aged 65 and over, younger people can be affected. Having dementia can cause loss of key functions to the brain, such as; loss of memory; confusion; speech and language problems; loss of ability to make judgements; loss of concentration; difficulty in processing information; changes in behaviour and personality. These all lead to a person not been able to function properly. The person’s ability to function deteriorates over a period of time and is usually at least 6 months before positive diagnosis of dementia can be made. Dementia is caused when the brain is damaged by diseases such as Alzheimer’s which is the most common of dementia, vascular which is a series of mini strokes,
Also, it requires a fast and secure communication to monitor real-time connection status to act as Energy Manager. [SANCHEZ]
What makes such a solution unique within this market and what benefits can it deliver to deployers of digital signage?
It runs a RealAudio Server over TCP with media stream transmission via UDP for supplying sound clips.
For viewers new to streaming video deciding which device is the best choice for them will be determined by price, features and the availability of their desired
Proxy / Cache Management: The Windows Media Server can be configured in such a way that it serves as reverse proxy server or as a cache / proxy server. This will allow to provide proxy and caching support to other servers. One of the major advantages of having a server that provides proxy and caching support for the media content is that it reduces operational costs and better streaming for users by offsetting the load from the ori...
In today’s technology boom, the new waves of doing business have transformed the way people shop and live. The same happened the way people access personal entertainment. With Internet, people can stream movie online without have to go theater, or the rental movie box.
Peer-to-peer (P2P) is a substitute network design to the conventional client-server architecture. P2P networks utilize a decentralised model in which each system, act as a peer, and serve as a client with its own layer of server functionality. A companion plays the role of a client and a server in the meantime. That is, the node can send calls to other nodes, and at the same time respond to approaching calls from other companions in the system. It is different from the traditional client-server model where a client can just send requests to a server and then wait for the server’s response.
