Chapter 3. Network Boundary Traffic Conditioners: Packet Classifier, Marker, and Traffic Rate Management
Traffic conditioning functions at the network boundary are vital to delivering differentiated services within a network domain. These functions provide packet classifier, marker, and traffic rate management.

In a network, packets are generally differentiated on a flow basis by the five flow fields in the Internet Protocol (IP) packet header: source IP address; destination IP address; IP protocol field; and source and destination ports. An individual flow is made of packets going from an application on a source machine to an application on a destination machine, and packets belonging to a flow carry the same values for the five packet header flow fields. Quality of service (QoS) applied on an individual flow basis, however, is not scalable because the number of flows can be large. So, routers at the network boundary perform classifier functions to identify packets belonging to a certain traffic class based on one or more Transmission Control Protocol/Internet Protocol (TCP/IP) header fields. A marker function is used to color the classified traffic by setting either the IP Precedence or the Differentiated Services Code Point (DSCP) field. Within the network core, you can apply a per-hop behavior (PHB) to the packets based on either the IP Precedence or the DSCP field marked in the packet header.

Oops - just realised it's 'marcat' and not 'marcador'. Sorry about that. I'm not properly awake yet!

So, maybe it should be 'marking' rather than 'marker'.

For example:

traffic marking

data flow marking
