Switch Fabric and Control Board (SCB)
At the heart of the Dynamic Services Architecture is the switch fabric and control board (SCB). The SCB transforms the chassis from a simple module enclosure into a highly effective mesh network. The purpose of the SCB is to allow all modules in the chassis to send traffic at extremely high bandwidth.
The Route Engine (RE)
The routing engine (RE) is tightly coupled with the functionality of the SCB and can be considered the central nervous system of the architecture. The RE is the control plane of the chassis, and provides overall management and communications to and from system administrators, as well as calculating route tables for routing network traffic.
Services Processing Card (SPC)
If the RE is the central nervous system of the chassis, the Service Processing Card (SPC), is the brain.SPCs are blades that provide the capacity to perform the heavy lifting of processing network packets.The chassis must have at least one SPC to operate.
The true elegance of this design is realized when more than one SPC is installed.Rather than the chassis now having two or more “brains,” as in traditional network architecture, the addition of a new SPC essentially results in a larger system that can perform many more tasks at a given time.
Input/Output Cards (IOC)
The chassis slots in the Dynamic Services Architecture are unique in that they are card-agnostic, allowing administrators to configure the architecture for their specific needs up to the limits of the chassis itself.For example, an organization that requires more processing capability, such as a military installation, may include more SPCs and fewer Input/Output cards (IOCs).An Internet service provider, on the other hand, may choose to provide a great deal of I/O for its customer traffic, while needing less raw processing power. As business requirements change, administrators may easily add IOCs and SPCs to reconfigure the architecture as needed.
Based on this agnostic slot design, the IOC can therefore scale independently — the chassis may be equipped with as many IOCs as there are available slots (with at least one slot for the SPC).The dynamic nature of the architecture then automatically maps each session to a SPC in real time as new sessions are received to be processed.
