Bindings
A binding is an association between elements within the system. There are two types of bindings: static and dynamic.
Static binding is accomplished through system configuration. Static bindings associate:
A specific logical interface (configured within a particular context) to a physical port. Once the
interface is bound, traffic can flow through the context as if it were any physically-defined circuit.
Static bindings support any encapsulation method over any interface and port type.
Static bindings support any encapsulation method over any interface and port type.
A service to an IP address assigned to a logical interface within the same context. This allows the
interface to take on the characteristics (that is, support the protocols) required by the service.
Dynamic binding associates a subscriber to a specific egress context based on the configuration of their profile or
system parameters. This provides a higher degree of deployment flexibility, as it allows a wireless carrier to
support multiple services and facilitates seamless connections to multiple networks.
