What is Retransmission, ARQ and HARQ? 

Posted by leopedrini Friday, June 22, 2012 11:12:00 AM Categories: Course
It's very important to use solutions that improve the efficiency of the adopted model in any data communication system. If the transmission is 'Wireless', this need is even greater. In this scenario we have techniques that basically checks, or verify if the information sent by the transmitter correctly arrived in the receiver. In the following example, we have a packet being sent from the transmitter to the receiver. If the information arrived properly (complete), the receiver is ... read more
 

IP Packet switching in Telecom - Part 4 

Posted by leopedrini Thursday, March 22, 2012 11:11:00 AM Categories: Course
And then we finally get to NGN signaling protocols: SIP and SDP. The picture below was extracted from RFC 3261 and gives a fairly good example of a SIP dialog between two users, Alice and Bob. The entities involved in the call setup are called User Agents (UA). UAs which request services are called User Agent Clients (UAC), and those which fulfill requests are called User Agent Servers (UAS). Although the basic operating mode is end-to-end, the model supports the use of intermediate ... read more
 

IP Packet switching in Telecom - Part 3

At the end of the precedent article I’ve told you that we’re going to dig a bit deeper into IMS and NGN signaling protocols (all this happens at the application layer of TCP/IP network architecture – see the first article of this series). Note: My blog Smolka et Catervarii (portuguese-only content for the moment) And so we shall do. I must warning you, though: you’d better fasten your seat belts, ‘cause there’s turbulence ahead. Few things can be more intellectually intimidating ... read more
 

IP Packet switching in Telecom - Part 2 

Posted by leopedrini Sunday, February 05, 2012 10:06:00 AM Categories: Course
So far so good… Like promised, let’s start our journey about IP networking in the telecom context from the ceiling and going down. So let’s understand what the heck is an “application”. Note: My blog Smolka et Catervarii (portuguese-only content for the moment) Technically we call an application any program that runs under control – and taking advantage of the services of – the operating system. That’s a fairly reasonable definition for our purposes, since all networking... read more

Posted by leopedrini Monday, January 30, 2012 10:05:00 AM Categories: Course
Let me start saying thanks to Leonardo Pedrini for the privilege of writing this series of articles for TelecomHall. He doesn’t do this frequently that I know of. If you like the articles and want to read more then go visit my blog: Smolka et Catervarii (portuguese-only content for the moment). // I’d better warn you right now that you’ll find my writing style quite different from Leonardo’s. While he emphasizes simplicity I’m a bit more fond of rigorousness. So I’ll make ... read more
