CTXDispatcher
CTXDispatcher — Click element;
CTXDispatcher
Ports: 1 input, any number of outputs
Processing: push
Define a context to classify packets among its outputs. It works much like Classifier, except the context will be grabbed by a CTXManager element that will handle classification and state management. See the MiddleClick paper.
It takes a serie of argument such as : CTXDispatcher(12/0806 20/01 0, 12/0806 20/02 1, 12/0800 2, - drop)
Where each argument defines a pattern and an output port. The output ports can be omitted if sequential, as much as the default rule. The following is therefore identical. CTXDispatcher(12/0806 20/01, 12/0806 20/02, 12/0800)
Each output rule cannot overlap with other rules. Eg you cannot have TCP packets going to port 0 and IP packets to port 1, as TCP packets are IP packets, it is impossible. You can use FlowContextDispatcher to have rules added in a "cascading else" fashion, i.e. if packets are not TCP but still IP packets, go to port 1. This is the default behavior of the context link (~>).
