Sitting at the center of a Diameter signalling network is the Diameter Routing Agent or SVI-DRA reducing complexity.
High volume traffic is managed through dynamic load balancing and configurable throttling whilst multi-vendor support is provided by onboard mediation.
Powerful routing, filtering and message manipulation is available as standard with complex policy building provided through the onboard policy engine.
NFV compliant the SVI-DRA provides a secure, scalable, high availability platform providing total control of an operators Diameter network.
The DRA acts as a mediation platform allowing complex routing and normalisation of messages across the Diameter network.
The DRA provides load balancing and throttling to insure the optimum management of the Diameter network.
Multiple Transaction Criteria Records (TCR’s) can be created to define transaction allowance and actions to take; queue, ignore and reject transactions.
Bind a session to one or cluster of devices. Start bind - Configure message or AVP to initiate bind. End bind on receipt of correct response or timeout.
Define Diameter Messages, AVP formats, contents and ENUM resolution. 3GPP and vendor specific dictionaries can be used.
Applied to avoid known issues by comparing message headers and AVP contents against configured black lists and white lists.
DRA can act as a redirect server, redirecting messages to other services, and to provide advanced load balancing and throttling.
DRA provides centralised routing based on message headers and AVP’s, reattemps, load balancing profiles and external lookups.
Regular-expression based manipulation of message header and AVP contents allows for removal, creation and replacement.
