The bottom line is maximum IP network consumers in the PH (approximately 68%) reside within PLDT's network control. >From the information I have it seems that for hosting commercial applications >(cloud based or otherwise) a Content Delivery Network could set up in almost >any and they should BUY a link to BTN (AS3491) asPLDT peers with them to get >bits into AS9299 (PLDT). Given the costs of ePLDT Vitro, PHIX, Globe MK2, ETPI, DataOne etc etc add infinitem add nausea one would have to compare them and add in the cost of a link to BTN or Reach. BTN is also a *related* company to Reach (AS4637) which is another option locally (over at RCBC Towers in Makati). I'm not exactly sure how BTN and Reach deal with each other business wise (kinda like I-Gate/Infocom and PLDT) but both BTN and Reach are part of the Hutchinson holdings from HK Telecom.. Anyways.. though dated 3 years ago the link posted shows how ePLDT/PLDT and Globes networks are set up.. however NOTE IN DIAGRAM the VIX router DOES NOT ALLOW TRANSIT. Its not an exchange router.. its ePLDT's border router. There is a significant difference. http://www.noaccess.com/~dsweeney/Y_Cache_PH.jpg Do good Stuff Dan On Jul 2, 2011, at 2:18 PM, Zak Elep wrote: > Great posts!
