RB750GL

The RB750GL is a small SOHO router in a white plastic case.

It has five independent Gigabit Ethernet ports and optional switch chip functionality for wire speed Gigabit throughput. It’s probably the most affordable MPLS capable Gigabit router on the market and now it is even more affordable than before. Compared to the previous model, the RB750GL has almost the same performance, but is significantly lower cost,
only $59.95!

With it’s compact design and clean looks, it will fit perfectly into any SOHO environment.

Box contains: RB750GL, plastic case, power adapter

All throughput tests done with Xena Networks specialized test system and RouterOS v5, according RFC2544, with Ethernet frame sizes 64, 512, 1518 bytes.
Each board is tested with specified number of Ethernet interfaces, to ensure optimal load on hardware.
Values in Italics indicate that the maximum possible throughput was reached, limited only by ethernet ports themselves.
