Submarine Cable Protection

The following YouTube video shows a way to protect submarine (telecommunication) cable. Anybody knows source of this video?

Cable Breaks - Again Around Taiwan

Since several days, some media have reported this issue. Some media have pointed to the Typhoon Morakot as the possible cause. Others (as cited by Commsday) mentioned a possibly undetected underwater earthquake. In common, seems they agree that the sources of these multiple cuts shall be something related to the natural happening. Which cable is impacted?

• SMW3
• EAC S2A1 (detected on 06/August); D (08/August); C (9/August)
• APCN2 S7 HK-TW? (09/August)
• APCN2 S1 SG-MY? (19/August)
• APCN (?)
• FNAL (HK-TW)

10 Gig-E IP Transit Prices

Firstly, I want to quote this : "Tata Communications says that its recently launched 10 Gig-E service now offers large capacity users a saving of up to 60% per megabit of traffic when compared to traditional Gigabit Ethernet services" (Commsday). Now, we might want to ask ourselves, without having to call any sales personal, how much does it actually cost? Price is something strongly not linear :-D .. it depends on this, that, these, and those. And often such factors can not be explained easily (if not at all :-D). Na Und? just want to know how much! :-D ... okay, look at the table below, it's a very simple model.

Submarine Cable Laying

If some days ago I mentioned two videos illustrating submarine cable repair/maintenance, this time I would refer to two other videos showing a basic scheme for submarine cable laying. As before, the first video is 3D (from GMSL??) while the second one is in the ASN fashion.. :-D

Internet : How It Works

How does the Internet work? The following two videos are good introductory material for answering that question. We used those for introducing our Department at TUHH to new undergraduate students. And couple of times I used also at ITB for the same purpose. The fist video (Warriors of the Net) is made by Ericsson MediaLab (?), narated in English and it's also available for download in several languages. The second video (Die Maus erklaert das Internet) is an episode from the "die Sendung mit der Maus" from the german WDR TV-broadcaster (sure, it's in German, but I think it's quite "selfexplanatory" :-D ).
