谁能解释一下是什么意思吗 谢啦
遇到一道难题 想求助下 问题是说什么原因会造成WAN PERFORMANCE DEGRADING,还有 if the problem is caused owing to the WAN capacity, what does that mean?

WAN = wide area network
wide area network capacity = 广域网容量 (straight from google translation)

Is this what you are after? If someone ask me this question face to face i will probably interpret it as the speed of my WAN connection

When managing wide area network (WAN) capacity, it's not enough to buy additional leased lines and hope for the best. The key question when addressing network capacity planning is, "How much is enough?" Network managers must decide if it makes sense to configure the minimum amount of bandwidth or to over-engineer the network. They must regularly review network performance to know what capacity is needed, now and in the future. And they must always balance the need to meet user performance expectations against the available budget.

WANs are typically built with high-capacity node-to-node links such as DS3 (45 Mbps) channels, with lower-capacity links such as DS1 (1.544M bps) connecting from the major nodes to office locations. Internet-based networks, such as virtual private networks (VPNs), use low- to high-speed access (based on the requirements) from the originating user site to an Internet node, and the same or similar configuration at the terminating site.

根据上面的粗略翻译一下,那就是广域网容量大小的问题啦,WAN内部是108MBPS或是54M的,出口如果用DSL的话也就1、2M吧,要是有更高的需求,就要按照需求增加出口或是做更复杂的网络拓扑结构了。
