Deploying Sandvine in WiMAX Networks
Sandvine’s platform elements are flexible enough to give communications service providers (CSPs) many deployment options across access technologies. Sandvine, as a true access-agnostic network policy control solution, can be deployed across different technologies and offers operators multiple options enhancing their deployment versatility.
This flexibility is enabled by the deployment versatility of Sandvine's platform element, the Policy Traffic Switch (PTS), which intersects data traffic. The location of the PTS in the network determines what the PTS can see and how it can impact use cases.
WiMAX refers to interoperable implementations of the IEEE 802.16 family of wireless-networks standards ratified by the WiMAX Forum.
Additionally, given the relatively low costs associated with the deployment of a WiMAX network in comparison with conventional network technologies like 3G, HSDPA, xDSL, etc., it is more economically viable to provide last-mile broadband Internet access in remote locations.
The network reference model supports unified network architecture for supporting fixed, nomadic, and mobile deployments, and is based on an IP service model. A simplified illustration of IP-based WiMAX network architecture has three logical parts:
- Mobile Stations (MS) used by the end user to access the network
- The access service network (ASN), which comprises one or more base stations and one or more ASN gateways that form the radio access network at the edge
- Connectivity service network (CSN), which provides IP connectivity and all the IP core network functions
Sandvine’s network policy control solution works with the all IP-based WiMAX architecture, where the PTS is deployed in the ASN layer alongside the ASN gateway. The below diagram shows a typical Sandvine solution deployed in WiMAX.
