HCL Sametime

HCL Sametime is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand HCL Sametime rather than just read about it. In short: HCL Sametime Premium (formerly IBM Sametime and IBM Lotus Sametime) is a client–server application and middleware platform that provides real-time, unified communications and collaboration for enterprises. Those capabilities include presence information, enterprise instant messaging, web conferencing, community collaboration, and telephony capabilities and integration.

Key takeaways

HCL Sametime belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HCL Sametime to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HCL Sametime from memory before moving on to harder problems.

Reference excerpt

HCL Sametime Premium (formerly IBM Sametime and IBM Lotus Sametime) is a client–server application and middleware platform that provides real-time, unified communications and collaboration for enterprises. Those capabilities include presence information, enterprise instant messaging, web conferencing, community collaboration, and telephony capabilities and integration. Currently it is developed and sold by HCL Software, a division of Indian company HCL Technologies, until 2019 by the Lotus Software division of IBM. Because HCL Sametime is middleware, it supports enterprise software and business process integration (Communication Enabled Business Process), either through an HCL Sametime plugin or by surfacing HCL Sametime capabilities through third-party applications. HCL Sametime integrates with a wide variety of software, including Lotus collaboration products, Microsoft Office productivity software, and portal and Web applications.

HCL Sametime (pre v11.5) comes in four levels of functionality: HCL Sametime Limited Use (Old name HCL Sametime Entry) provides basic presence and instant messaging. HCL Sametime Standard provides additional functionality to HCL Sametime Entry, including:

rich presence including location awareness rich-media chat, including point-to-point Voice-over-IP (VoIP) and video chat, timestamps, emoticons, and chat histories group and multi-way chat web conferencing contact business cards interoperability with public IM networks via the HCL Sametime Gateway, including AOL Instant Messenger, Yahoo! Messenger, Google Talk and XMPP-based services. open APIs that allow integrations between HCL's own and other applications Sametime Audio/Video Services supports audio (e.g. G.722.1) and video codecs (e.g. H.264) HCL Sametime Advanced provides additional real-time community collaboration and social networking functionality to HCL Sametime Standard, including:

persistent chat rooms instant screen sharing geographic location services HCL Sametime Unified Telephony provides additional telephony functionality to HCL Sametime Standard or HCL Sametime Advanced, including:

telephony presence softphone click-to-call and click-to-conference incoming call management call control with live call transfer connectivity to, and integration of, multiple telephone systems - both IP private branch exchange (IP-PBX) and legacy time-division multiplexing (TDM) systems HCL Sametime Gateway provides server-to-server interoperability between disparate communities with conversion services for different protocols, presence information awareness, and instant messaging. HCL Sametime Gateway connects HCL Sametime instant messaging cooperate communities with external communities, including external HCL Sametime, and public instant messaging communities, such as: AOL, AIM, ICQ, Yahoo, Google Talk, and XMPP. HCL Sametime Gateway replaces the Sametime Session Initiation Protocol (SIP) Gateway from earlier releases of HCL Sametime. The HCL Sametime Gateway platform is based on IBM WebSphere Application Server, which provides failover, clustering, and scalability for the HCL Sametime Gateway deployment. The product is shipped with the following connectors: Virtual Places, SIP, and XMPP. More protocol connectors may be added.

Worked examples

Example 1 — a first encounter with HCL Sametime

Start with the simplest possible case. Write down what HCL Sametime claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to HCL Sametime before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about HCL Sametime ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of HCL Sametime

In research: HCL Sametime appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses HCL Sametime in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: HCL Sametime is common in secondary-school and first-year university syllabi. It links to neighbouring topics Instant messaging server software, Internet software for Linux, Lotus Development software, so understanding it makes those chapters shorter.
In everyday life: Look for HCL Sametime outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
