A Frame Relay Customer Network

Tue, 18 Jul 2017 19:45:02 GMT

A bunch of my previous posts have laid the foundation for future discussions of the frame relay protocols which had achieved widespread use and acceptance in the early 90s. While some of these technologies have mostly been eclipsed in North America and elsewhere, you can still find pockets of Frame Relay and ATM usage today.

How Banks Can Monetize Their APIs Part 2

Mon, 17 Jul 2017 23:10:30 GMT

Beyond the different maturity levels of offering APIs for monetization, there are different methods or plans for monetization, and in most cases, you will use a variety of these plans based on the type of API and how it is used:

How Banks Can Monetize Their APIs Part 1

Going even further, banks may take another logical step by looking to aggregate APIs across multiple financial institutions through their own single API. This may be a good offering to broker style app makers in the mortgage, loan and insurance space. Or the bank could offer their own brokerage app in these spaces. Service and transaction fees would likely be the right revenue model for this method.

The Network-to-Network Interface

Thu, 13 Jul 2017 22:12:53 GMT

Until now, my recent posts have focused on the relationship between a single user and a single network, or User Network Interface (UNI). To extend the user's communication beyond a single frame relay network, the FRF has developed a Network Node Interface (NNI) specification.

Design Problems with Frame Relay Networks Part 3

Tue, 11 Jul 2017 15:54:16 GMT

The excess burst-rate parameter (Be) lets users exceed the Committed Information Rate for brief periods, as required by such "bursty" applications as Local Area Networks. The access rate, measured at the physical interface to the network, provides an upper limit to the rate at which users may offer data to the network.

Design Problems with Frame Relay Networks Part 2

Tue, 11 Jul 2017 15:37:22 GMT

Frame relay networks have two ways of notifying the network of and/or controlling congestion: explicit congestion notification and implicit congestion notification. ECN uses the FECN and BECN bits included in the T1.618 Address field to notify the network of congestion.

Design Problems with Frame Relay Networks Part 1

Tue, 11 Jul 2017 14:53:37 GMT

Committed Burst Size (Bc), the maximum amount of data in bits that a network agrees to transfer under normal conditions, over a measurement interval T

The Local Management Interface

Tue, 11 Jul 2017 14:44:49 GMT

After several (typically six) link integrity verification polls have been issued, the user requests the status of all PVCs on the interface. The resulting full status message response contains information on every PVC configured on that bearer channel.

Final Thoughts on IGMP

Thu, 29 Jun 2017 21:32:49 GMT

Along with some other topics, this series will start to look into the details of UDP for User Datagram Protocol and discuss how UDP differs from TCP as a transport protocol.

IGMP: Leaving a Host Group

Tue, 27 Jun 2017 23:19:54 GMT

As the final step of initialization, hginit calls hgjoin to place the host in the all-hosts group. Once a host has joined the all-hosts group, it will receive IGMP queries.

IGMP: Sending Reports

Tue, 27 Jun 2017 00:11:47 GMT

Once igmp_in accepts a message, it uses macro IG_TYP to extract the message type. If the message is a query, igmp_in calls igmp_settimers to start a timer for each entry in the host group table.

IGMP: Membership Reports

Tue, 27 Jun 2017 00:03:48 GMT

Because the standard specifies that the report for each host group should be delayed a random time, igmp_settimers calls function hgrand to compute a delay.

Technology has no boundaries

Mon, 26 Jun 2017 12:41:58 GMT

Well, I've scared a few fish and some people even tried to save me until I convinced them that I am human and not the great white whale.

So, as I sat down, a thought came to mind. Technology really has no boundaries. If you think about it, no matter where in the world you go, you will find the same technology. It may be a different brand, it may be locally made but the basic technology

Beach blogging

Mon, 26 Jun 2017 12:33:15 GMT

This time I'm sitting here at a beach and it's a very picturesque location. The water is a lovely turquoise colour and very shallow. Unfortunately I can't go in it as I am suffering from a touch too much sun. Poor little me :).


Instead, I am writing another article. Not on my tablet this time but on a five inch screen telephone. A HTC one m7 if you really want to know. There

Are tablets dead?

Mon, 26 Jun 2017 04:43:17 GMT

Just to make you all jealous I want to let you know that I am currently on holiday in Greece. It is a very nice place and I didn't bring my computer with me. So how am I able to type this article? 


Well I sort of lied here. I actually have three computers with me. I have two mobile phones and a tablet. I am currently using the tablet, with no external keyboard attached

Get your facts straight!

Fri, 23 Jun 2017 04:29:26 GMT

As you probably know I write programs for a living. More specifically I write programs which interact and control different devices. These varied devices are often controlled by their own firmware.


Firmware is just another name for a program which has been installed on the device to control it and is not changeable by the normal user. Just about, all actually, smart electronic

Computer clean thyself!

Thu, 22 Jun 2017 09:32:03 GMT

They say a clean desk is a sign of a sick mind. I have to admit that my mind must be as healthy as an ox because my desk is as cluttered as a teenagers mind when he looks at a playboy picture (although I have heard that playboy is not as, er, graphic as it used to be).


When it comes to computers and operating systems however, that is a different story. I will literally spend

Microsoft opens up

Thu, 22 Jun 2017 07:06:15 GMT

I knew it would happen sooner or later. There is no possible way that the closed source model will ever be a successful one for software which is integral to computer usage.


For years Microsoft denied this. They called open source software a cancer and a disease and vowed to destroy it. Well maybe not in those exact words but very similar.


Finally Microsoft

Other Dead LAN Strategies

Tue, 20 Jun 2017 23:59:52 GMT

Companies such as Bridge Communications, Ungermann-Bass, AT&T, and Wang were major players, or at least they were attempting to be.

The changes in social media

Tue, 20 Jun 2017 15:57:46 GMT

Even before the Arpanet allowed people to communicate with each other across the network there has been a social media. People for some reason just love to communicate with each other. Whether it is by the office water cooler talking about what Johnboy did to Maryjane or over the wire sharing questionable photo's and movies.


In the beginning there were things called bulletin

DEC's Networking Strategies

Sun, 18 Jun 2017 03:09:58 GMT

An important deviation from past DEC policies was extensive support for interconnection to networks and facilities outside DNA, including, in particular, support for IBM's SNA and Novell's NetWare.

IBM's Impact on LANs

Fri, 16 Jun 2017 00:11:00 GMT

Particularly in the areas of microcomputers, LANs, and enterprise networking, IBM's insistence that its customers remain "pure blue" ran against both the economic and technological developments set in motion before 1990.

Power for the people gadgets

Wed, 14 Jun 2017 06:51:59 GMT

Just about, actually I would say all, technological knick nacks and doo dads we love to wear, carry and play with need electricity to run. It is these busy bee electrons which are tirelessly working to provide for our entertainment, computational and living needs.


This power comes from several sources and for us, it starts with a plug and a wall socket. That, coupled with

Light 4j Docker Container Chassis Ideal for IOT

Wed, 14 Jun 2017 00:43:47 GMT

ResinOS and Light 4J based containers could offer some of the highest performing utilities in the IOT space.

Network History - APPC/APPN Notes Continued

Wed, 07 Jun 2017 22:26:08 GMT

In the paper, "Advanced Peer-to-Peer Networking," Joyce and Walker have offered the following characterizations of APPN and APPC:

IBM Networking Strategies and APPC/APPN

Mon, 05 Jun 2017 22:38:40 GMT

As their names imply, APPC, Advanced Program-to-Program Communication, deals with programs, while APPN, Advanced Peer-to-Peer Networking, deals with networks.

The programming life continues

Wed, 31 May 2017 16:18:30 GMT

In the previous article, I mentioned how I worked for a company which was a real sweatshop, high-pressure environment which was really not healthy for mind and soul. Suffice to say I did not renew my contract with that company.


Consequently, other companies I have done programming for have also been wildly different. Some were pretty laid back and allowed my creative juices

The programming life

Wed, 31 May 2017 15:54:50 GMT

I have been involved with computers since before I found girls interesting. The only problem is that girls never found me to be interesting but that is another story.


It was my first computer, with it's very well detailed basic programming book which taught me how to program. From there it was keying in programs from magazines, finding out why those keyed in programs didn't

What a cutie!

Wed, 31 May 2017 10:42:21 GMT

I just got an interesting mail today, not of the dead tree variety but of the live electron variety. This mail told me that the latest version of my favourite programming platform, Qt (supposedly officially pronounced "cute" but I have always pronounced it as "Q,t" and probably always will) has been released.


This in itself is not earth shattering news as Qt is always releasing

The good, bad and the ugly

Wed, 31 May 2017 06:09:39 GMT

If it wasn't for technology we wouldn't be where we are right now. It has lifted the human race to heights (literally) that have never been achieved in the history of the Earth before. The only place for humans to go now is up (again literally :) ).


Technology has increased our lifespan, our health and standard of living. It has made the world a smaller place (not literally
