A method (1002, 1102) for measuring performance of a network, comprising: providing an innermost probe packet, the innermost probe packet having an innermost destination address corresponding to an intended final destination entity for the innermost probe packet; generating a first probe packet, the first probe packet including: a first destination address that identifies a first network component in the network; and the innermost probe packet, which is encapsulated in the first probe packet through at least one layer of encapsulation; sending the first probe packet to the first network component of the network based on the first destination address associated with the first probe packet; at the first network component, generating first mirrored information, the first mirrored information providing content that is associated with the first probe packet; providing the first mirrored information to a collection and analysis system, CA system,; decapsulating the first probe packet to produce a second probe packet, the second probe packet including the innermost probe packet and a second destination address; sending the second probe packet to a second network component that is associated with the second destination address; at the second network component receiving the second probe packet, generating second mirrored information, the second mirrored information providing content that is associated with the second probe packet; providing the second mirrored information to the collection and analysis system; at the collection and analysis system, collecting one or more instances of mirrored information produced by one or more respective network components in the network, in response to injection of one or more probe packets into the network; and providing information regarding at least one network-related behavior based on said one or more instances of mirrored information. providing an innermost probe packet, the innermost probe packet having an innermost destination address corresponding to an intended final destination entity for the innermost probe packet; generating a first probe packet, the first probe packet including: a first destination address that identifies a first network component in the network; and the innermost probe packet, which is encapsulated in the first probe packet through at least one layer of encapsulation; a first destination address that identifies a first network component in the network; and the innermost probe packet, which is encapsulated in the first probe packet through at least one layer of encapsulation; sending the first probe packet to the first network component of the network based on the first destination address associated with the first probe packet; at the first network component, generating first mirrored information, the first mirrored information providing content that is associated with the first probe packet; providing the first mirrored information to a collection and analysis system, CA system,; decapsulating the first probe packet to produce a second probe packet, the second probe packet including the innermost probe packet and a second destination address; sending the second probe packet to a second network component that is associated with the second destination address; at the second network component receiving the second probe packet, generating second mirrored information, the second mirrored information providing content that is associated with the second probe packet; providing the second mirrored information to the collection and analysis system; at the collection and analysis system, collecting one or more instances of mirrored information produced by one or more respective network components in the network, in response to injection of one or more probe packets into the network; and providing information regarding at least one network-related behavior based on said one or more instances of mirrored information.
