| | Blueprint: Metro Ethernet |
 | | The key technical challenge of SpyNet was to provide replica traffic from the InteropNet (using SPAN ports, external and internal taps, either optical or copper, ranging from 100M, to 1G or even 10G) and to channel this data to a variety of monitoring tools. |
 | | SpyNet is essentially the virtualization layer between the network and the tools, providing customizable data access and matching the bandwidth requirement of the business enabling production network and the bandwidth available on the mission critical monitoring tools. |
 | | Again, the fundamental building block is the data access switch which acquires traffic from multiple SPAN ports, aggregates and filters the aggregated traffic according to specific VLAN range (in order to segregate the total traffic by business groups), and multicasts the customized traffic to different tools. |
