This chapter will cover Trio Inline Services and enumerate the different services that are available through the power of Trio. Many Juniper MX customers often ask, “Why is the bulk of the cost in the line cards?” The answer is because all of the awesome is in the line cards! Think about all of the typical services in the line cards from Chapter 1: line-rate forwarding, class of service, access lists, and much more. That’s just the tip of the iceberg. Trio inline services go above and beyond and introduce sampling, network address translation, port mirroring, and tunnel protocols.
