PacketSaver™ - reduces network load
Conventional VoIP gateways can be very inefficient when it comes to packetizing voice. Quintum’s Tenor eliminates the risk of high bandwidth usage for VoIP calls. But Tenor uses patent-pending PacketSaver technology to multiplex voice calls traversing the network to reduce the overhead created by IP packet headers. The result is lower bandwidth requirements so you don't have to worry about creating excessive additional load on your existing network. This is also an especially important consideration for remote offices with low-speed connections

Quintum Technologies has directly addressed this issue with its multi-switching VoIP architecture, which instantaneously re-routes voice traffic from the IP network to the public switched network if conditions on the IP network threaten to compromise call quality.

Now, Quintum has gone a step further in ensuring the quality of VoIP with its innovative new PacketSaver ™ technology. PacketSaver multiplexes multiple individual VoIP sessions into consolidated IP packets, significantly reducing the total amount of bandwidth needed to support voice calls over IP networks. This more efficient approach to transporting VoIP results in three key benefits:

1. By minimizing the bandwidth required for VoIP traffic, PacketSaver lowers the likelihood that other congestion on the network will threaten voice quality.
2. Because PacketSaver reduces the total number of packets used for VoIP traffic, it also reduces the chances of packet loss – another factor that can affect voice quality.
3. In minimizing the amount of bandwidth required for VoIP, PacketSaver contributes to the overall efficiency of the IP network – reducing congestion and lowering overall infrastructure costs.

This last benefit is particularly appealing to VoIP service providers, whose profitability is largely contingent on their ability to deliver high-quality voice services over IP networks at the least possible cost.

How PacketSaver Works
In the case of voice over IP, packets are usually created as a VoIP gateway receives a voice stream. The gateway compresses the voice and digitizes it into a packet payload, adding a header with destination information. With conventional gateways, packets are created as each individual voice stream hits the gateway. This results in the creation of tremendous header overhead. The network – which usually has lots of data packets flowing over it already – can easily become saturated, causing congestion and even lost packets. This can compromise the voice quality, as well as the overall health of the network.

Quintum’s PacketSaver technology is a packet assembly technique that queues up several voice and/or fax packets and multiplexes them into one or more larger packets, without introducing unacceptable delays in packet processing. In other words, packets from one or more sampled voice conversations are multiplexed (or “packed”) together into one larger multiplexed voice packet headed for the same destination device on the other side of the network. When the packet is full, or the pre-determined time limit for packet construction is reached, it is sent to the common destination point. When this multiplexed packet reaches the destination device, it is then de-multiplexed, allowing the packets for each original voice conversation and/or fax transmission to be distributed to their appropriate end-point destinations. A sophisticated, patented algorithm controls exactly how packets are identified for multiplexing and then effectively de-multiplexed at the other side of the wide-area network (WAN connection). This tunable multiplexing control mechanism also ensures that PacketSaver does not introduce unacceptable processing delays into the network.
