I added the ability to generically add overlays to my network map. A function is provided with the visualisation options, the graph nodes and links and the canvas to draw on. I need to do some testing to make sure this is the best and easiest way to do this. I am going to firstly look at overlaying VLAN data on to the karen example.

The honours conference is coming up on the 31st of August, so I have been starting to think about what is going to go into my presentation. There was talk about presenting to wand as a practice with the others at some point before the say.

This week I worked on getting my Karen example tidy enough for Richard to present to the crew down in Wellington on Thursday. This involved making a drag & drop position editor to make it easier to make changes to node positions. I fixed up the CSS layout to make it look more like a dashboard. I also did some cross browser testing and it seems to work okay on most latest version browsers. There were some exceptions, but mostly just performance issues.

I have made the Karen demo public here:

Any feedback is most welcome :-D

Created a basic ISP for 514 this week. PPP client connecting to a NAS running PPPoE and authenticating via another server running freeradius.

I have also been working on getting a cleaner example of my network maps for Richard to show Karen next time he visits. I have been altering the overview plots to show and additional view for each deeper level. This will make it more useful when you zoom in further.

My health has been pretty bad lately. I have a flu for a week and a half, then crushed my hand on Sat and finally have been diagnosed with tonsillitis today :-S

Made a 520 interim presentation and presented it to the rest of the students on Wednesday. Steve is recording all of the presentations through Panopto. It was quite interesting listening (and watching) myself speaking. I need to cut back on the ummmms! Apart from that, the audience seemed engaged and asked thoughtful questions afterwards.

I have started looking in to producing a more stable and complete version of the Karen weather map such that I can evaluate my map with them. I also finally started playing with the CRCnet hosts file from Jamie.

Started classes again this week - COMP518 and COMP514.

I fixed up my broken force directed layout type for the network map and started looking at the most adaptable way of allowing multiple layers in a graph.

Have started putting together a few slides for my talk next week to the class about my 520 project progress.

Over the past week I added a couple more features to my network map such as an overview box and a debugging mode. The debugging mode just shows useful things like the frame rate, current scaling and translation offsets, and shows the outlines of nodes.
I think that I have now read and briefly summarised most of the relevant publications for my lit review.
Stayed at Hahei all weekend! Life of a student.

I collected some more useful publications for my lit review and started looking at ways to produce an overview of the network map.

I had a look at ways of visualising bandwidth in an effective way on a network map. I am experimenting more with an idea that incorporates width, height and colour of edge sections. Where width codes the bandwidth utilisation percentage, height codes the actual throughput and the colour codes some categorical severity measure.

See: http://joeloughton.com/blog/wp-content/uploads/2011/06/bandwidth2.png

Coding the height of a line in a map that has zooming capabilities does not work well. I have tried scaling the line height in proportion to the current zoom level which seems to be working well.

I spent the week finishing of my exports visualisation assignment and presenting it to the class.

This week I wrote my interim report for 520. Also planned out what I need to get done next semester. I need to convert this into some sort of timeline at some stage. It was a busy week with presentations and tests to prepare for. One last assignment left now at this stage but that will be next weeks job.

Weekend off!
