Multiple Interface Realms
The multi-interface realm feature lets you group multiple network interfaces to aggregate their bandwidth for media flows. In effect, this feature lets you use the total throughput of the available phy-interfaces on your Oracle® Enterprise Session Border Controller for a single realm. Multi-interface realms are implemented by creating multiple steering pools, each on an individual network interface, that all reference a single realm.
Note:
Labels that read 'physical interface' in the diagrams below should be understood to reference the phy-interface configuration element.Without using multiple interface realms, the basic hierarchical configuration of the Oracle® Enterprise Session Border Controller from the phy-interface through the media steering pool looks like this:
In this model, one (non-channelized) network interface exists on a phy-interface. One realm exists on one network interface. One or more steering pools can exist on one realm. Within each higher level configuration element exists a parameter that references a lower level configuration element in the Oracle® Enterprise Session Border Controller’s logical network model.
The multi-interface realm feature directs media traffic entering and exiting multiple network interfaces in and out of a single realm. Since all the steering pools belong to the same realm, their assigned network interfaces all feed into the same realm as well. The following diagram shows the relationship in the new logical model:
The advantage of using multi-interface realms is the ability to aggregate the bandwidth available to multiple network interfaces for a larger-than-previously-available total bandwidth for a realm. In the illustration below, three phy-interfaces each have X Kbps of bandwidth. The total bandwidth available to the realm with multiple network interfaces is now 3X the bandwidth. (In practical usage, interface-1 only contributes X - VoIP Signaling to the total media bandwidth available into the realm.)
