P2P & Skype traffic control in ISP networks

it seems some ISPs have started to introduce management facilities into their networks. Is those products of carrier level? reference: http://webreprints.djreprints.com/1341970908457.html Joe __________________________________ Do you Yahoo!? New and Improved Yahoo!

Comments or suggestions required Internap FCP 500 vs. OER
by Drew Weaver 10 Nov '05

10 Nov '05

We're looking at possibly purchasing a Internap FCP500, everything I hear about these boxes is good. We are simultaneously trying to decide if Cisco's Optimized Edge Routing solution (built into the IOS) should be a consideration as an alternative? We're basically just trying to find a solution to traffic engineering. That will A) work, B) be supported and C) be somewhat easy to manage. I had heard that Cisco planned to release a hardware solution based off of OER but never got around to it due to lack of interest possibly? I'm just looking for your opinions on the two more or less. We have also looked at the Arbor product, but we need something that actually can implement routing policies as well as provide statistics on what is going on in our infrastructure. Thanks, -Drew

Phone ouages grow more severe

Networks Are Taking Longer To Repair Despite Focus On Boosting Reliability By JESSE DRUCKER and AMY SCHATZ Staff Reporters of THE WALL STREET JOURNAL November 10, 2005; Page B10 Despite a new focus on strengthening traditional U.S. telecommunications systems to withstand terrorism and natural disasters, telephone-network outages have grown more severe and are lasting longer to repair. [...] In the past four years, the median duration of an outage was 3.3 hours -- "significantly higher" than the 2.86 hours it took to restore operations during the first eight years data were tracked, according to the report. The severity of the outages -- which takes into account several factors, including the number of customers affected -- has also jumped over the past four years. [...]

Our peering setup is a follows: - Our peering exchange connection goes into switch A - Switch A has a dark fibre connection to switch B, which is in a different PoP - Our peering router is connected to switch B We use spanning tree across our network to allow the VLANs connectivity across our network. The peering exchange has an MoU that only 1 MAC address should be visible on their switch. However they see 2 MAC addresses on our port. - MAC address of Peering router - MAC address of the port they are connected to on switch A Is there any way to prevent switch A from presenting the interface MAC address? Or is this a symptom of spanning tree that cannot be stopped? Your input will be most welcome. The config on switch A is as follows: interface GigabitEthernet0/5 description Peering Link switchport access vlan 148 switchport mode access speed nonegotiate storm-control broadcast level 5.00 no cdp enable spanning-tree portfast spanning-tree bpdufilter enable spanning-tree guard root Regards Simon Brilus

Many ASes explicitly do *NOT* >want to send traffic to any other AS. They only want >to send traffic to customers, vendors or business >partners of some sort. You are right, but this was not the point I was trying to make on this slide. The point I was trying to make is: A site is assigned an AS if it has a network that is connected to the global Internet and wants to send traffic somewhere. (If not, why bother to get an AS?) One of the rules in the policies is that the AS is returned when the need disappears. So, very naively, I'd think that for each assigned AS there is at least one path announcing the address space in that AS to somebody else. I immediately agree that there are cases where an AS does not want to send traffic to another AS, or prefers not to use a path even though it is available. I also agree that there are cases where a network is not visible at all on the Internet and a private AS cannot be used. However, I do not believe that these cases account for 1/3 of the AS out there.
