Peering Wars

This was actually a quite old story issued by Renesys several months ago and it was also presented at NANOG 43 (June 2008). The story took a case of network-depeering and the actors were Cogent and Telia. At that time, both Cogent and Telia are considered as "near" Tier-1 providers. Why "near"?
  • Cogent gets (got?) transit from NTT (formerly Verio) to reach AOL (ATDN?).
  • Telia appeared to get transit from Verizon to reach certain networks.
Additionally, it is worth to mention that
  • Tier-1 providers act like a cartel and have no incentive to add members
  • "Near" Tier-1 providers can try to buy their way into the club (via "paid peering")

Telkom's Backbone

Several times ago, I mentioned Telkom's national backbone in this post. According to records published by KOMINFO, as of Q4/2005 Telkom owns 10,816 km fiber optic cable. The backbone network is distributed as follows:
  • Surabaya-Banjarmasin-Makassar : 2,088 km (constructed in 2000)
  • Trans-Java : 2,605 km (2000)
  • Jakarta-Medan-Batam: 2,990 km (2004)
  • Batam-Singapore-Bangkok: 1,043 km (2004)
  • Dumai-Melaka: 161 km (2005)
  • Banjarmasin-Balikpapan : 955 km (2005)
  • Makassar-Palu: 974 km (2005)

Palapa Ring (6)

Below are some updates for the Palapa Ring project as of September 2008. It seems that there are some route adjustments; and that now the project schedule is more realistic, taking into account current market situations.
  • 2 FP for repeatered system
  • 12 FP for inland and repeaterless system
  • Construction begin on April 2009;
  • RFS final (all segments) on September 2011
  • Section 1 Mataram - Parigi
  • Section 2 Palu-Sorong
  • Section 3 Makassar-Sorong
  • Section 4 Makassar-Mataram/Kupang
  • Section 5 Sorong-Jayapura
  • Section 6 Fakfak-Merauke

Jakarta (IP) Bandwidth Price

I followed some traces left by Pak Meneer and was delivered to his records at Opisboy. This is claimed to be an "Informal ISP Technical ( dir-pji-like :p )" forum. Comments ? :-D Well, for non-local readers, "dir-pji" could be understood as "indonesian ISP Executives/VIPs" or as the forum of ISPs' owners/high-rank officials. It is "dir-pji-like" ? Personally, I would say "better-than-dir-pji" :-D Reasons? he..he..he. Don't take it seriously or even start thinking about that!! :-D

Back to bandwidth. According to Pak Meneer, the condition is as follows:

Jakarta Metro Backbone

It seems that everybody in Jakarta want to have his own metro :-) Currently many companies have built their metro infrastructure to support their business, particularly in big cities such as the Greater Jakarta, Surabaya, Medan, Bandung etc. These include :
  • well known telcos (TELKOM/TSEL, ISAT, XL, other?)
  • successfull ISPs (BizNET,CBN, other?)
  • VSAT network operators (CSM, Lintasarta, other ?); and
  • backbone operators (ICON+,PowerTel,Napinfo,Moratel, other ?)
Recently, PT. iForte Solusi Infotek announced, that they have finished the construction of their fiber optic network which is using (and installed simultaneously with the development of) the TransJakarta busway infrastructure (map see below). They currently offer connection/access services called M-Wifo which are basically WiFi (802.11n compatible) access and fiber bridging. To my guess, it might be a RoF (Radio over Fiber) system.

Bandwidth "Under Water"

As Asia NetCom (currently PACNET) introduced its idea for EAC Pacific one or two years ago, they underlined the fact that due to underserved routes from South and South-East Asia, Japan-US connections have become a bottleneck. They have shown a picture similar to one below. It has attracted my attention since it split Asia into three regions together with their connectivity parameters. At least, it was something different than we might see in the free version of TeleGeography's reports/databases :-D CMIIW!

After a closer look at the given bandwidth figures and comparing with other publications (TeleGeography etc.), I have to conclude that it isn't real i.e. ANC possibly gave the capacity based on design numbers (fully equiped system). Right ?? Wrong ??

How Much Bandwidth do Indonesian ISPs Have ?

Though there are many Internet and NAP service providers running their business since several years ago, "big Internet pipes" are only owned by the (former-telco-only) giants: Indosat, Telkom, Excelcomindo, and Telkomsel. They may have a total international IP bandwidth more than 1 Gbps. Unfortunately, as usual :-D I don't have complete, official, clear, and confirmable numbers for that. Maybe next time, I would come with a simple calculation using several rough statistics found in the media and balanced with some cases (personal experiences).

Unity Cable System

Unity is a new multi-terabit transpacific cable system with Google's taste :-D As you can see at this post, I've misunderstood that EAC Pacific would completely be a new transpac cable. It shall actually be a part of the Unity cable. To my knowledge, there are currently three competing parties offering new Asia-US connections:
  • Trans-Pacific Express (TPE) : Verizon's Taste :-)
  • Asia America Gateway (AAG)
  • Unity : PACNET, Google etc.
Any other planned cables ?

PT. Power Telecom (PowerTel)

Is there any relation between PowerTel Indonesia and PowerTel New Zealand/Australia ? Honestly I've just heard about this company a few months ago and about last week I was quite surprised when several media quoted the company press release that they are ready to offer services in Jakarta Bandung and that they are in the last stage of the preparation of Java-wide fiber optic infrastructure. Well, "Gut gemacht! Gratuliere!"

National and Regional RENs

Actually since a long time ago I want to write threads about RENs (Research and Education Networks). Why? Simply because they were the origin of the current Internet and they still have a major role in creating advances in networking technologies. This time I would not start with an indonesian case (if INHERENT or Jardiknas can be categorized as a National REN/NREN), but with european cases.

Excelcomindo's Backbone

As of Q4/2006, Excelcomindo has installed and operated more than 2,300 km submarine and more than 5,500 km terrestrial fiber optic cable. This information can be used to check or balance my former calculation (however this was for Q4/2007, since it is based on the information from Kominfo on that time frame). I'm just thinking to derive a progress factor, something like fiber deployment rate each year each operator (km/year), just to have a rough metric for measuring operators' progressivity. Whether somebody out there (in Kominfo or in the operators) is already doing this??

Mobile Network Coverage

How many BTSs are needed to completely cover a city on average? 50 ? 100 ? more/less ? If each operator has its own tower, then it would be 250 to 500 towers in a city (assuming there are 5 operators, 1 BTS each tower).

Around two years ago, when I came back from Germany after several years leaving, almost every 1 minute or maybe less of my trip from Jakarta to Bandung (also inside the cities) I saw a BTS tower!! Several times later people told me that indeed due to "cellular wars", our cities have turned into "Hutan BTS" (BTS forrests). Well this is the fact. This might:

Indosat's Backbone (2)

I've just found another version of Indosat's backbone. For me it looks a bit better than the previous one, though some links might still be not so accurate.

Palapa Ring (5)

The last non-incumbent member of Palapa Ring consortium, PT. Powertek Utama Internusa has indirectly cancelled its membership (update to this post) . Thus the consortium currently consists of the four-biggest telcos:
  • PT. Telekomunikasi Indonesia (Telkom)
  • PT. Indosat
  • PT. Excelcomindo Pratama
  • PT. Bakrie Telecom

Highlight XL (Excelcomindo)

In this new "Highlight" thread, I would archieve some actual facts (of my interest) related to indonesian telcos/ISPs.

Currently, XL (Excelcomindo Pratama) is the third largest telco in the country. This is currently justified if we look at the customer base and some financial performances of the company. The current champion is Telkom Group (inc. Telkomsel) while the "vize" champion is Indosat Group. The position might change in the (near) future, especially since XL "moves" quite progressive after TM acquisition and after the former Indosat CEO Hasnul Suhaimi leads this company.

International IP Bandwidth

Currently I have only some official information specific to Indosat. This was presented by Indosat several times ago (Apricot 2006 Bali ??). However, it belongs to the "biggest" pipes owned by indonesian ISPs.

Indosat's IP Transit Bandwidth:

Wiring Kalimantan

As in the case of Sumatera, the biggest three telcos are developing their optical transmission infrastructure in Kalimantan. As you can see below, they have chosen to follow terrestrial paths approximately parallel to the coastal line of Kalimantan. This might mirror the actual social and economic development in Kalimantan. Festoon optical networks could still be possible to be deployed as backup for current almost linear topology.

TIS Cable

TIS stands for Thailand Indonesia Singapore. As indicated by the name, it is an optical submarine cable spanning from Songkhla (Thailand) to Batam (Indonesia) via Changi (Singapore). TIS cable was the first submarine cable project of PT. Telkom.

Indosat's Backbone

In this post I just want to put some additional information (maybe "another view") of the Indosat's backbone mentioned in the this post. The map below was presented by Indosat in Apricot conference several times ago (2006, in Bali I guess). Does Indosat use any consortium's cables (SMW, APCN) just to link to Singapore ?
