Re: Question on peering strategies

fabric. Is this just because that shared fabric has geographical reach, as in the case of IXReach? I also see that links provided in this discussion show Europe based networks that are using this peering type more often. Is this widely accepted that US market is totally different from Europe?

Question on peering strategies

? Can the networks do load balancing on the two connection and essentially use them as primary routes? Best Regards Reza Motamedi (R.M) Graduate Research Fellow Oregon Network Research Group Computer and Information Science University of Oregon

Figuring out traceroute

all different ports of one router? I think the other explanation is that there is switch (or something that does not have IP footprint) between `From` side and `To` side. How probable do you think this second explanation is? Best Regards Reza Motamedi (R.M)

Inferring the location points of traffic exchange between two networks

uld be a flag to differentiate records showing iBGP vs eBGP. On the same note, if we issue the commands on a router other than the border router in San Fran, is there any difference in the output of show commands? Now how are things different if we actually run the commands on that gateway ro

Re: interconnection costs

All the costs of HW, SW, personnel, administration, and perhaps transmission between colos (including remote peering, being waved to another location, tethering) would be the same, right?

interconnection costs

there is no single answer as different businesses may have different pricing models. I hope the discussion can help me understand the whole ecosystem a little bit better.

Re: What can I infer from show ip route and similar BGP commands?

Thanks Joel for your detailed explanation. It was very informative. I have been using routeviews for sometime, but given that I could get this amount of information from other sources, I decided to give this a try. On another note, do you think there is any value in checking the next hop IP? I
