我的水平很潮，抛砖引玉，也请高手赐教~
也想画的比如水牛同学，也要开始画啊！
就用球球的图，希望球球妈妈不介意哦！
1。打开原照片，新建一个layer，用来画轮廓。用brush tool，我喜欢用一个小号柔边
的，in the brush window, check on Noise.基本上描着球球的轮廓画就好了，
因为是漫画，可以比较概括，不用画太多细节（我自己是水平太差，画不细），
表情可以夸张一些，自己设计一下。
2。再建一个新layer，用来画背景。用brush tool，我常用一个大号柔边笔刷，mode我
会选成Multiply,透明度也降一些，这样不同的颜色会有叠加，色彩丰富些。画上颜色后，
可以选择filter, blur, Gaussian Blur，让背景朦胧。再建一个新layer，
用来画前景，重复刚才的操作，不用blur太多，远虚近实嘛。
理论上不应该把背景和前景都画的差不多了再画主体，应该同时铺进，不过这个图相对
简单，就直接一步到位了。
（请忽略2图中球球身上的阴影——我是画着画着就画错层了 -_-;)

所以可以让EE的人单独做好优化好这一个hop，后面进入有线网络后，再让CS的人按照

比如第一个hop，EE就用他们各种point-to-point的information theory的fancy模型搞

发帖数: 1950 | 27 我对路由器转发包的理解是，

PC A 根据PC B的IP地址决定选择router 1，然后运行ARP协议，得到router 1的MAC地
址，将其作为linker layer frame中的destination MAC address。
router 1检查IP包，根据PC B的IP地址决定选择router 2，然后router 1需要运行ARP
协议知道router 2的MAC地址，然后将其作为linker layer frame中的destination MAC
address。
router 2作类似的事情，
router 3收到IP包后，发现PC B跟它在一个网络，运行ARP协议，得到PC B的MAC地址，
将其作为linker layer frame中的destination MAC address, 并将包直接发给PC B。
