Radware FireProof SynApps 2.51



Radware's product is unique among the products we tested in that SynApps is an add-on to Radware's switch product line. Although it finished at the rear of the pack and can't match rivals in features, it does come at a bargain if you already have a Radware switch in your network. This product is well-suited as a supplement, but it's not a full-blown QoS device.

Overall, SynApps' management features are better than Lightspeed's, but its bandwidth control and reporting lag behind the standalone boxes. Bandwidth is controlled by weighted-fair queuing or CBQ. You can set policies based on source and destination IP addresses, port numbers, diffserv value, or IP ToS bits. The switch we tested had eight network ports, more than any other entry. Each port can have available bandwidth specified. There are seven priority levels, and a real-time level as well. Minimum bandwidth and maximum borrow bandwidths can be set, but only per class, not by connection.

SynApps offers virtually no reporting elements, except for showing current bandwidth usage per policy. Of course, if you have a predictable type of traffic flowing across the switch, that may be good enough, especially for the price.
