The other option we are looking into is the DCSG (Dissagregated Cell Site Gateway) Project a initiative by the telecom Infrastructure Project with many hw and sw vendor following the open source model.

Capacity/speed is an issue with me, so I think I introduced some possible bottlenecks above 4.5Gbps using MPLS/VPLS in my own network which is Mikrotik. VPLS endpoints I don’t think were/are hardware offloaded, so required some great CPU capacity at the edge and core for large transport. I also think I had MTU issues with so many layers of “layer2” stuff going on inside and outside of MPLS tunnels, native interfaces, VPLS endpoints, bridges and VRRP interfaces along with VLAN at some endpoints. However, with the right equipment (not Mikrotik) MPLS is fully capable and large networks use them to diversely traverse redundant paths back to a central core. My problem also was geo-diverse BGP cores to different providers as stated below. I was running EVERYTHING on a Mikrotik 1072 CCR, lol! It still drives me crazy hunting down issues where I still have MPLS/OSPF/BGP/VRRP/VLAN on one device across multiple interfaces, lol!

Is routing faster on MikroTik by using MPLS/VPLS? No Do you gain extra capacity by reducing the router load per packet by using MPLS? Yes, think looking at 4-bytes of data vs 40. Is it 10 fold increase, no but you get the point. What is the big deal about MPLS without VPLS? Just that it does get you a bit of extra capacity. Bout it. Why does everyone want to run VPLS? VPLS gets you the IP and subnet savings. You do need to design your core network correctly to handle this. If you have a single core router and all of your tunnels go to that, then yes if it goes down yes your tunnels are down, but may of our customers have to have redundancy, so multiple edges, connected to multiple cores, connected to multiple VPLS termination boxes, connected to multiple PPPoE servers. Etc. The core is VERY robust, but the general network is not. This also does not work very well if your have multiple geographically diverse BGP feeds, i.e. everything goes back to the datacenter and that’s where it is, great, but otherwise, it gets to the point that it not worth the effort. L2VPNs? Weill there are a few customers that prefer them, but in all honestly there is better, more secure, and faster protocols out there. Keep in mind that L2VPNs are fine if all of the customers are on your network, but they seldom are, so you will need a plan for those guys as well. My questions is why do you build your network to deliver something that people don’t want, a layer 2 network connection. If you are delivering Pipes then sure, but you have to have the capacity and availability to do so. Most Wisps, not all, don’t have this figured out. 99% of the time, they can make more money by providing a managed L3 solution than L2 anyways.

Reasons for doing this are typically to achieve better IPv4 utilization (not having to route a block of IP's to each POP and maybe wasting IPv4, etc). Another common use-case is providing L2VPN services for customers (connecting multiple locations together, etc).

I mean I've been reading the white-papers and such, and I see it brings some features to the table, but when are we going to use them? Routing speed: * MPLS can make forwarding decisions faster. When they made this in the 1990's I'm sure that was a big deal, but I'm doubting whether there is really measurably better latency on modern hardware. Is there? Traffic Engineering: * It can do redundancy, but it seems to rely on the routing protocol (eg OSPF) to know which paths are up. I don't understand what that buys us. * It can do load sharing on unequal paths. Admittedly that's very hard to do with L3 routing protocols, and that would have been extremely useful at one point in time. But how often does that happen now that we're in a world of gigabit and 10gigabit connections? L2 tunneling * It can transport L2 traffic over an L3 network. It does it with less overhead (8 bytes) than any other method I can think of. I don't really see a downside to this. So are people running MPLS just to get VPLS tunnels, or do you find that the other tools in the MPLS toolbox matter in today's world? -- AF mailing list AF@af.afmug.com<mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com<http://af.afmug.com/mailman/listinfo/af_af.afmug.com>
