彩铃即个性化回铃音业务，它是一项由被叫用户订制的替代普通回铃音的业务。在发展初期，用户只能在网站上下载流行金曲、经典音乐，但随着这项业务的迅速发展，各种个性化的“酷铃”、“另类炫铃”不断被开发出来，并得到用户追捧。不但运营商和内容提供商赚了个盆满钵满，还顺带着产生了一个新职业——彩铃写手，据说仅仅凭简单的录音设备和音频编辑软件，这些写手就能日进斗金。 这段话主要告诉我们( )。

Border Gateway Protocol(BGP) is inter-autonomous system (96) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (97) count is not the preferred route. For example, we may not want a packet through an not secure even though it is the shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that (98) . A router that receives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (99) routing is also not a good candidate for inter-autonomous system routing because an Internet is usually too big for this routing method. To use link state routing for the whole internet would require each router to have a huge link state database. It would also take a long time for each router to calculate its rousting (100) using the Dijkstra algorism.
