拜托啦
1) Consider some of the pros and cons of virtual-circuit and datagram networks.
a) Suppose that in the network layer, routers were subjected to stressful conditions that might cause them to fail fairly often. At a high level, what actions would need to be taken on such router failure? Does this argue in favour of VC or datagram architecture?
b) Suppose that in order to provide a guarantee regarding the level of performance (for example, delay) that would be seen along a source-to-destination path, the network requires a sender to declare its peak traffic rate. If the declared peak traffic rate and the existing declared traffic rates that have been declared are such that there is no way to get traffic from the source to the destination that meets the required delay requirements, the source is not allowed access to the network. Would such an approach be more easily accomplished within a VC or datagram architecture?

1.思考虚拟电路和自带寻址信息的网络的利弊
2.假如在网络层，路由器受到压力状况，将常常可能引起他们无法正常工作，在高层上，什么举动将需要承担这种路由错误？这争论时间参与VC还是自带寻址信息体系的活动。
3.假如为了提供保证关于一级别那些将会沿着源至目标（端到端）的路径的性能（适合于：实例，延迟），网络要求一个发送器去判别他的最高传输量，如果宣称（理论）的传输速度和实际的传输量已经判别没有方法从源至目标去获取合适延迟要求的传输量，源头就不允许访问网络层，用VC还是自带寻址信息系统比较容易完成
翻译得狗屁不通，知识不理解，太过专业
楼主要的是专业英语高手吧，不是网络高手！
