谁能帮忙翻译如下的一段英文,设计IP 地址以及BGP路由?
Covered prefixes are usually due to practical purposes such as load sharing or multihoming. To help infer the actual routing practice for covered prefixes, in Table 1 we classify covered prefixes into four classes based on their advertise- ment paths relative to that of their corresponding covering prefixes, with two of them further classified into sub-classes. The classification is inclusive, that is, every covered prefix falls into one of the classes. Figure 15 shows examples for all the classes and sub-classes, where a solid line with arrow between two ASes represents a provider to customer AS re- lationship, which is inferred by using Gao’s algorithm [6], a line without arrow shows the cases where the relation cannot be directly determined by the routing table, and a dashed line with arrow indicates prefix advertisement. Note that
the line between two ASes represents a logical connection which correspond to more than one physical connections be- tween the two Ases. Also note that this classification does not include level-2+ covered prefixes, which make less than
5% of the routing table entries. Due to space limit, we skip the discussion on the motivations for various prefix adver- tisement practices; interested readers can find more detail in [9].

涵盖前缀通常归结于实用目的,例如负载分配或multihoming.为了推断涵盖前缀的实际的路由练习实践,在表1我们根据与他们的广告宣传路径相关的对应的覆盖物前缀而将涵盖前缀分成四类,同时其中的两类再进行进一步的二级分类.分类是包含的,也就是说,每个涵盖的前缀落入了其中一类当中.图15显示有关所有一级分类和二级分类类的例子,凡带有箭头的两个自治域之间的实线代表了通过使用高推断的算法[6]得出的供应商和客户之间的关系,那些没有箭头的线表示了不可能直接地依据路线表就能得出关系的案例,那些带有箭头的虚线表示前缀广告.请注意,两个自治域之间的连接线代表了两个自治域之间一个对应一个以上的的物理连接的逻辑关系.并且注意这个分类不包括2+级涵盖前缀,利用路由表项目不超过5％.由于空间极限,我们跳过了关于各种各样的前缀广告实践的动机的讨论 ; 感兴趣的读者能找到更多细节
