Border Gateway Function (BGF)

Junos® OS, Release 10.3

The BGF application is part of the Junos Session Border Control (SBC) portfolio. It is an individually licensed software application that handles SBC media tasks. The BGF application provides media gateway control and media latching functions, Network Address Translation (NAT) and network address port translation traversal, Differentiated Services Code Point (DSCP) marking and rate limiting, and more.
