Summary
The Trio chipset offers line rate performance with the ability to offer inline services. As new versions of Junos are released, the Trio chipset has the ability to be upgraded and offer additional services as well. This new architecture of offering inline services in the Trio chipset frees you from having to invest in additional hardware for service processing. However, the Trio inline services are basic in nature as of Junos 11.4, and any advanced features such as carrier-grade NAT (CGN) requires the MS-DPC.
It’s amazing to consider that inline services such as J-Flow, NAT, GRE, and port mirroring are available from the line card itself. One of the big benefits of keeping the services within the Trio chipset is low-latency and near line rate performance. This is because the packet doesn’t have to travel to a services card, be processed, and sent back to the line card; everything is done locally within the Trio chipset.
