* Layer: A collection of Ports with common Characteristic Information
So to describe a Layer you have to describe all the Ports that the Layer includes?
No, we indeed should define Layer as a property of each Port. A Layer should stands on it's own, and the word "collection" is probably not the correct word to use. If you have a suggestions for a better definition, please do let us know! (Here are the ITU definitions, I'm certain you can do better than this. Characteristic information (CI): This is the combination of the adapted information with additional information (layer information) that is transported across the network. Some of the layer information can remain unchanged across the network, though it can be read within the network, while other layer information may be altered within the network. Adapted information: Adapted information is the information that is transported transparently across a server layer network. Adapted information is the client information encoded in such a manner that it is transportable across the layer network. This encoding can include labelling of the client information in order to distinguish the client information within the context of a single instance of adapted information. Adapted information is the construct that allows independence between client and server. The termination sink function extracts layer specific information (e.g., encoding, labelling, fields for sublayer OAM) to create the layer adapted information. The extracted information is the layer information (LI), such that the adapted information is equal to the characteristic information minus the layer information. The operation of the termination function is independent of the client layer network. ) Regards, Freek
