Dialogic I-Gate 4000 Session Bandwidth Optimizer Core X
Deliver a large reduction in the bandwidth requirements and the traffic load

Overview:

The Dialogic I-Gate 4000 Session Bandwidth Optimizer Core X (I-Gate 4000 SBO-CX) is a standalone equipment solution designed to deliver a large reduction in the bandwidth requirements and the traffic load (packets per second) for VoIP traffic, allowing for significant CAPEX and OPEX savings.  It is a versatile solution, which can be deployed in applications such as:

• Between VoIP media gateways (VoIP traffic optimization)
• Between 3G mobile media gateways (Nb traffic optimization)
• Between a 3G mobile media gateway and a Radio Network Controller (IuCS traffic optimization)
• Between a Session Border Controller and VoIP media gateways (VoIP traffic optimization)
• Between a Session Border Controller and 3G mobile media gateways (Nb traffic optimization)
• Between Session Border Controllers (VoIP and Nb traffic optimization)

The I-Gate 4000 SBO-CX can leverage sophisticated in-house bandwidth and IP packet rate optimization technologies, while preserving the quality and reliability of the original VoIP, Nb and IuCS traffic.  By combining high-quality VoIP, Nb and IuCS traffic optimization techniques, the I-Gate 4000 SBO-CX can serve as a powerful CAPEX and OPEX savings option for operators that have deployed 3G mobile networks as well as for operators and service providers using VoIP interconnecting networks.

High Bandwidth Savings

The I-Gate 4000 SBO-CX can significantly reduce the bandwidth required for 3G Nb and IuCS traffic, as well as VoIP traffic from service provider or enterprise media gateways, while preserving the original voice quality. The I-Gate 4000 SBO-CX automatically detects and processes the Nb, IuCS or VoIP traffic streams without interworking with a control or signaling element.

Usually, deployed VoIP and 3G mobile media gateways use bandwidth optimization techniques such as encoding and silence suppression; however, the overall optimization level of these systems can be relatively low. In contrast, the I-Gate 4000 SBO-CX uses distinctive bandwidth optimization algorithms and techniques to optimize the already-compressed VoIP, Nb or IuCS traffic without degrading the original traffic quality. See Figure 1, Chart A example and accompanying description.

IP Network Optimization

The I-Gate 4000 SBO-CX can significantly reduce the original VoIP, Nb or IuCS packet rate (packets per second) load while providing full application and services transparency. Packet rate reduction can help release core IP network router resources, which, in addition to contributing to CAPEX and OPEX savings, can help enhance overall Quality of Service. See Figure 1, Chart B example and accompanying description.

Figure 1 shows an example that compares the bandwidth requirements (Chart A) and the packet rate (Chart B) of VoIP traffic before and after an I-Gate 4000 SBO-CX solution has been deployed. In Chart A, the green column depicts the bandwidth requirements before deploying an I-Gate 4000 SBO-CX solution and the blue column depicts the bandwidth requirements after deploying an I-Gate 4000 SBO-CX solution. Similarly, In Chart B, the green column depicts the packet rate before deploying an I-Gate 4000 SBO-CX solution and the blue column depicts the packet rate after deploying the an I-Gate 4000 SBO-CX solution.
