Re: question about bgp incremental updates

Hi, I can think of two reasons for such behavior: - one of the attributes of these routes changed suddenly, so they have been reannounced by your peer, - you sent a 'route refresh' request to this peer, asking him to reannounce all his table. Other than that, I don't see why a peer would resend lots of already-announced prefixes.. cheers, Mateusz On 08/04/2014 04:29 AM, Song Li wrote: > Hi everyone, > > I have a question about bgp updates: > > BGP uses an incremental update strategy to conserve bandwidth and > processing power.

Greenfield Access Network
by Colton Conor 01 Aug '14

01 Aug '14

If a new operator or city is building a greenfield access network from the ground up, what software and hardware is needed in the core network to provide and manage residential and business internet services similar to the likes of AT&T, Comcast, and Google Fiber? Television and Telephone services are not to be considered only internet. Assume hypothetically the operator already has the following in place: 10 GPON OLTs Chassis from an access vendor in 10 POPs around town (each POP has 1 Chassis). Each OLT Chassis has 4 10G Uplinks back to the core. Dark fiber going from the POP locations back to the core location Assume a 32:1 way split, and each OLT chassis has enough ports populated to serve the area. 10,000 GPON ONTs. The ONTs can be put in routed gateway or bridged mode. Assume you are building a network designed to serve 10,000 subs All the fiber splitters, ducts, fiber, etc connecting the OLTs to the ONTs is already in place ASN from ARIN /20 of IPv4 space and /32 of IPv6 space from ARIN 4 burstable 10G internet connections from 4 tier 1 internet providers Questions are: What is the ideal way to aggregate the 40 10G connections from the uplinks of the chassis? I would guess a 10G switch since 10G ports on a router would be much more expensive? Which router is recommended to handle 4 10G internet connections with full tables, and then at least 4 10G ports going back to the 10G aggregation switch? How do you handle IP address management? a /20 is only 4096 IP addresses, but the network would have potentially 10,000 customers. Assume that getting more space from ARIN is not an option. Is CGN an option? Dynamic IP addresses? DHCP? How do you separate users and traffic? VLANs, Service VLANs, Per Customer VLANs, Usernames? Passwords? PPPoE? MAC Separation? Is a BRAS or BGN functionally really needed or are these older concepts? If CGNAT or DHCP is needed, what will host the CGNAT or DHCP service? The core router, a linux box, or something else? What about DNS? Is a firewall needed in the core? What else is needed? Is there a guide out there somewhere? I know many cities are looking at building their own network, and have similar questions. Access vendors are willing to sell gear all day long, but then they leave it up to the operator/city to answer these harder questions. How would you build a access network from the ground up if you had the resources and time to do so? Would you even use GPON? Even if GPON was not used and another access technology like AE, VDSL2, or wireless was used I think many of these questions would be the same.

Netflix To Cogent To World
by Jay Ashworth 01 Aug '14

01 Aug '14

While thinking about this double play over the weekend, a very interesting chain of thoughts occurred to me. If I were Netflix, why would I buy all my transit from Cogent[1], given Cogent's propensity for getting into peering fights with people *already*, even before *I* start sending them 1000:1 asymmetric outbound traffic? Presumably because they're offering me a helluva deal on the bandwidth. So why would Cogent offer Netflix a helluva deal? Perhaps because they were smart enough to see how popular NF would become... and thought it would make an excellent stalking horse in their own peering fights? Who's gonna depeer Cogent *now*? Cheers, -- jra [1] This is my understanding, though of course I'm not privy. -- Jay R.
