Providing additional networking services on top of routing and switching is critical to the success of any good network architecture. Networking services includes features such as:

  • Sampling information and statistics

  • Network Address Translation (NAT)

  • Port mirroring

  • Generic Routing Encapsulation (GRE) and IP tunneling

  • Logical tunnels

Historically, routers have required a separate Services Module to provide additional features. One of the key differentiators of the Trio chipset is its ability to integrate network services without the requirement of an additional Services Module. With each new Junos release, it’s possible to add new features such as inline services within the Trio chipset.

Providing network services as part of the MPC line cards, which use the Trio chipset, offers some distinct advantages:

Total Cost of Ownership

As network services become available through the Trio chipset, you are no longer required to purchase an additional Services Module. However, the real cost savings manifests itself in an additional FPC slot that is now available because the Services Module isn’t required. This additional FPC can be used to provide additional WAN ports to realize previously lost revenue.

Configuration

The configuration of inline Trio services is largely the same as services on the MS-DPC. The largest difference is the requirement to set aside a specific amount of bandwidth on the Trio chipset to be reserved for inline services.
