请帮忙解析下面的句子，要分析语法结构，谢谢！

There exists, also, a need for strong authentication of such traversal in as fine-grained a manner as is practical.
This requirement stems from the realization that client-server relationships emerge between the networks of various organizations, and that such relationships need to be controlled and often strongly
authenticated.
此外，我们还需要对这类防火墙穿越实现强鉴权，并且强鉴权的实现方式应当兼顾细致缜密和高效实用两个方面。
这个需求是基于下列认知而形成的：在不同组织的网络互连时、必然存在客户端-服务器的关系；这样的连接关系是必须受控的，并且通常以强鉴权的方式来控制。

语法结构其实没什么难点，你看懂 as... as...就不会有任何问题了。
