Exploring Telkom / Telkomnet

I've captured robtex-view of Telkomnet two or three months ago (see below). And this is relevant with the conversation between Sang Pemimpin and Meneer Tutut.

First of all, "the edges of an AS graph represent logical relationship between ASes and do not represent the form of the physical connection" (Lixin Gao). Short speaking, this describes more-or-less the BGP-view from a specific AS.

Telkom currently owns at least 2 ASes : AS7713 and AS17974. All external connections seem to be happened at AS7713, while AS17974 looks to be a "domestic island". As we can see below, BGP-views from these ASes are different. Two or three years ago, I found a good source related with this issue made by Timothy Griffin. I have to check this again, or maybe if you have interest, you could try "google" using his name.

As mentioned by Meneer, the following ASes are adjacent to AS7713 as "upstream" (in the CIDR terminology - not necessarily real Telkom's upstream providers):
  • AS24077 --> TMHK-TRANSIT-AS-HK-AP TMHK Global Transit
  • AS24399 --> ABN-PEERING-AS-AP Asia Broadcast Networks Peering AS
  • AS38154 --> PSN-NAP-AS-ID PT. Pasifik Satelit Nusantara
  • AS30362 --> HPT-ASN - Hawaii Pacific Teleport LP
  • AS4657 --> STARHUBINTERNET-AS Starhub Internet, Singapore
  • AS4788 --> TMNET-AS-AP TM Net, Internet Service Provider
  • AS6762 --> SEABONE-NET Telecom Italia Sparkle
  • AS7473 --> SINGTEL-AS-AP Singapore Telecommunications Ltd
Looking at the number of BGP advertisements, it seems that AS7473 (Singtel) and AS24077 (Telekom Malaysia Hong Kong) plays important roles for Telkomnet's network. Disagree ? Any advise?






*Update 04/09*
Sedangkan untuk kapasitas bandwidth, Nyoman mengatakan, Telkom yang sebelumnya memiliki sekira 13 Gbps, saat ini bertambah menjadi 17 Gbps. Dan pada bulan juli mendatang Telkom akan mendapatkan sekira 40 Gbps sebagai bagian dari keanggotaan Telkom dalam konsorsium Asia-America Gateway (AAG).

thanks for response.
I am Agree that As number not represent physical connection because, phy and as number are in different layer OSI.

and for Meneer Tutut.
thanks for your information of another upstream in telkom.

for reability internet connection in indonesia.

Existing PT Telkom's upstream went to Singtel and TM cause related with private cable TIS cable and DMCS cable. Maybe Telkom also have a backup link via satellite to HKG or SNG. And soon Telkom will get some additional link to Singapore once BSCS cable completed to connect to AAG cable and if Telkom also buy some capcity to Matrix cable to Singapore
