Hello Albert, > If a router is to be installed in a repressive country, then it is certainly possible to have whatever layer 3-7 filters implemented in that router, as just such filters are implemented in "firewalls." Or, if an Internet site wants to serve customers with special location-based apps, they can certainly do so without having to impact the IETF standards (either by requiring GPS input into the app, or by asking the user to provide his location).
How would you know if a mobile router crossed the city or country boarders, so you can change the "firewall" rules? it could be very short distance in terms of physical locations and defiantly won't be reflected on topology. and it's not about firewalls in repressive countries, it's about classification and marking where you can implement location-based policies like QoS, ACL, routing .. etc. > It just seems unwise, to say the least, to build this feature directly into layer 3 or 4 protocols, where it becomes ubiquitous, and where the user is not in control of it. Today locations are assigned to IP addresses without user awareness or control, everytime I do ip-lookup query I find myself in a different city because I am connected to a different ISP which has it's IP subnet registered to a different area. I remember few years ago when there were sanctions on Iraq, people used to download software updates through VSAT as their IP address shows Germany or Netherlands. I am suggesting to make locations more accurate and controlable through OS and network devices, exactly like IP addressess (user can change it's IP address and router can also modify the header information in case it's required). > Or, if a group wants to develop a location-based routing protocol, they can certainly do so, without forcing this information to impact IETF standards. I totally understand, appreciate and highly recognize your efforts to safeguard IETF standards, i wish you guys the best of luck and looking forward to see more promissing projects.

At the same time, I would like to raise my concern regarding the http location request which will not be detected by layer-3 devices (Routers), I am anticipating that in the future, GPS capability will be added to the router itself (just like smart phones) and packet marking and classification based on geo-location will be required. QoS, firewall and routing based on geo-location will be highly demanded when mobile routers move from one geo-location to another which has different regulations/electronic laws. Here is an example, if your router is within city-X and this city has very good electronic and copyright laws, then users will have relaxed network security settings, but what if the very same router moved to city-Y which according to its law, certain websites should be blocked (like facebook in china for example) .. these rules based on geographic location won't be feasible unless the mobile router has a GPS and can read/write coordinates to layer-3 packets.
