> ## Feature # 6: Peer map

> #### Visualizing traffic patterns

> The Peer Map view is a powerful tool for visualizing network traffic in a Packet File window or Capture window. The Peer Map uses line weight and line color to show the volume and protocol of traffic between nodes. The nodes themselves can be color-coded for protocol and size-coded for traffic volume and can show icons for node type, based on Name Table entries.

> The Peer Map displays only the packets visible in the Packets view. Hiding and unhiding packets in the Packets view can be used to alter the Peer Map. In addition, the Peer Map view contains its own tools to control the display of nodes and types of network traffic. This lets you quickly create a picture of all the traffic in a particular protocol, for example, or all the nodes sending or receiving multicast traffic.

> The Peer Map displays the nodes around an elongated ellipse. Communications are shown by a line connecting each two peers. The color of the line denotes the protocol, its thickness the volume of traffic. When you drag nodes to new positions, the lines rubber-band.

> To use the Peer Map:

> 1. Open a Capture window and begin capturing traffic.
> 2. Click the Peer Map tab to open the Peer Map view.
> 3. In the Display Options section at the right of the Peer Map view, choose IP Map from the Map Type drop-down list.
> 4. Notice that only nodes using the IP protocol are displayed.
> 5. Change the Traffic Type setting, using the drop-down list, from the default All to Unicast or Multicast. Notice how the Peer Map changes to display only the nodes sending or receiving these types of traffic.
> 6. Restore the Traffic Type setting to All.
> 7. Go to the Protocols section and deselect some of the protocols shown there. Notice that the lines indicating traffic between nodes in the Peer Map disappear as their protocol is disabled (unchecked) in the Protocols settings pane.
