11.3. Node, Attack, and Monitor Models
11.3.1. Node Model
A node in the network performs routing and switching. With the switching capability, a node can propagate a crosstalk attack from one attack channel to other normal connections. Some nodes can also support monitoring capabilities. Such a node is referred to as a monitor node. Otherwise, it is a nonmonitor node.
11.3.2. Crosstalk Attack Model
As shown in Figure 11.1, a crosstalk attack connection usually only affects another connection on the same wavelength. We define the following terms to describe a crosstalk attack model:
Upstream and downstream neighbor nodes. For a node on a certain path, its upstream neighbor node (UNN) is the previous node on that path. Similarly, its downstream ...
