1. An arrangement comprising a network tap, the network tap comprising:
- a first port for receiving data packets from a network, wherein the data packets specify a destination address;
logic communicatively coupled to said first port, said logic adding first metadata to each data packet of a first plurality of data packets comprising a percentage of said data packets from the network, thereby forming a first plurality of metadata-enhanced data packets, wherein said first metadata includes data specifying a geographic location of said arrangement, and wherein said geographic location is also a location where said first metadata is added to said first plurality of data packets, and wherein the data specifying the geographic location is distinct from a respective network address in each data packet of the first plurality of data packets;
a second port for forwarding said first plurality of metadata-enhanced data packets from the network tap to a monitoring tool remote from the network tap, thereby enabling monitoring of the network by said monitoring tool remote from thenetwork tap, wherein said first metadata comprises data employed by said monitoring tool remote from the network tap to perform network monitoring tasks; and
a third port for forwarding the data packets on a path to the destination address.

Abstract
Methods for enabling monitoring a network with a monitoring tool are disclosed. The method includes receiving data packets and adding metadata to the data packets, thereby forming metadata-enhanced data packets. The method also includes forwarding the metadata-enhanced data packets along a path toward the monitoring tool, wherein the metadata pertains to data employed by the monitoring tool to perform network monitoring tasks. Arrangements for performing the same are also disclosed.

11. A method performed by a network tap, the method comprising:
- receiving data packets from a network, wherein the data packets specify a destination address;
adding first metadata to a first data packet of said data packet and to each packet of a first plurality of data packets comprising a percentage of the data packets from the network, thereby forming a first plurality of metadata-enhanced data packets, wherein said first metadata includes data specifying a geographic location of said arrangement, and wherein said geographic location is also a location where said first metadata is added to said first data packet and a first plurality of packets, and wherein the data specifying the geographic location is distinct from a respective network address in the first data packet and each packet of the first plurality of data packets;
forwarding said first metadata-enhanced data packet from the network tap to a monitoring tool remote from the network tap, thereby enabling monitoring of the network by said monitoring tool remote from the network tap, wherein said first metadata comprises data employed by said monitoring tool remote from the network tap to perform said network monitoring tasks; and
forwarding the data packets on a path to the destination address. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
