Traffic from Columbia goes from our primary gateway to mbone.appliedtheory.com, and then to pen-mbone-1.sprintlink.net, which, I've been told, is a Sun SPARC machine of some kind running Solaris. It has a large bunch of tunnels hung off it, and it leaks packets like a sieve. When connectivity isn't screwed up like it is now (more on this in a second), it loses anywhere from 40% to 60% of all the traffic passing through it. The shuttle mission astronauts can hear NASA better than we can when a mission is being multicast. Recently though, things have gotten even weirder. It looks as though the particular chunk of the MBONE on which reside has been split off from the rest of the world. I only see one thing in the session directory these days, and that's Radio Free Vat. The only people I see on that group are either closely peered to Sprint or overseas somewhere. I've been told that plans are afoot to obtain an MBONE tunnel from an alternate source because Sprint's service is so spotty. About the only good thing about the whole mess is that at least now I can actually listen to Radio Free Vat. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
