Please remark as well that it isn't shure if the new IPv6 routing can be implemented to support secure transmissions over TCP/IPOSS. 2.0 CONTENT 2.1 MAKING A FIRE Making a fire is the first of all that you have to do. For further assistence please ask your local scout or fire founder. 2.2 BUY A INDIAN When you are looking for a indian please check if there isn't "made in Taiwan" sign on in. Indians aren't originaly from Taiwan so please have a look at the quality. I personaly doesn't bother about that because some copies are ratter better than the original ones. 2.3 COMPATABILITY Please ensure that your communications partner has the same kind of Indian. There are indians that only support asynchronous or synchronous (a lot more expensive usualy) smoke signs. Please remark that transfer speed depends on the weather conditions. A too long distance between the different indians stocks can reduce the transmission quality. 2.4 ROUTING To ensure a clean routing you have to distribute routing tables to each indian you are using. In this version they don't support RIP and probably will not do this in future. 2.5 TTL Please increase the TTL up to half an hour to ensure that your packets don't get lost. Some hops, especially if the load of your network is low, will be burnt out and have to make a new fire before they can transmit a new packet. It is possible to increase the TTL in the night to one hour. An other common possibility is to send a ping all 20 minutes so the fire keeps on burning. but please remark that indians, cause they aren't produced in a big number of items yet, are expensive and will not work for long if they are used permanently. A golden rule says: if you increase the Time-To-Life for your transmitted packet, you increase the TTL of your indian to. 3.0 THINGS THAT HAS TO BE DONE 3.1 HA high-avaibility isn't yet support but seems to be possible if you are using several indians at the same hop. in future it will be possible to load balance the traffic over several indians. the problem is the dissolution of the different smoke-streams over a long distance. we are working on solutions based on different colored smoke-streams 3.2 TCO AND ROI The total cost of ownership is enorme today, but will be decreasing at the time we can export this TCP/IPoSS to countrys like Iran, Irak and other non democratic regimes because TCP/IP over smoke signs is not covered by the high technologie export prohibition. 4.0 CONCLUSIONS Please ensure that indians work only good if they have good conditions. This mean direct sight to the next hope and working conditions between 20 and 30 degree celsius. The todays cost are enorme and the transmission speed is slower than over a strowstem-line. that is perhaps the reason why nobody is using it. But with implementing the UDP,WSP and wireless application protocol there is real chance for TCP/IP over smoke signs!
