Introduction

This chapter describes the Oracle Communications Session Border Controller’s static flows feature. Static flows allow network traffic that matches specific criteria to pass through the Oracle Communications Session Border Controller unrestricted. Static flows are unidirectional. This feature lets you steer traffic toward a particular destination based on its original characteristics. Static flows can range from being widely accessible to very restrictive, depending on the values you establish. Static flows are used for transporting a variety of signaling messages through the Oracle Communications Session Border Controller to achieve vendor interoperability. The Oracle Communications Session Border Controller supports the following types of Static flows:

• IPv6 to IPv6 flows
• IPv4 to IPv6 flows
• IPv4 to IPv4 flows

Note:

Traffic that traverses the Oracle Communications Session Border Controller in two directions, such as ICMP requests and responses, requires static flows configured for both directions.
