high-capacity Gigabit Ethernet switch designed for the network core of large enterprise and campus networks. 3Com directed The Tolly Group to benchmark the Layer 2 performance of the 3Com Switch 7700R against two switches from Cisco Systems, Inc. -- the Catalyst 4507R and the Catalyst 6509.
Engineers subjected each of the devices to Layer 2 throughput tests using packet sizes of 64, 512 and 1,518 bytes. Tests show that the 3Com Switch 7700R was the only device tested that achieved zero-loss wire-speed performance across all packet sizes tested when handling Layer 2 traffic in an adjacent port-pairing scheme.
Test highlights include:
- The 3Com switch delivered 100% of theoretical maximum zero-loss throughput at all frame sizes tested, while Cisco Catalyst switches delivered considerably less
- It generated 96 Gbps aggregate throughput consistently across 48 ports in full-duplex mode, versus Catalyst switches achieving 20 to 89 Gbps
- It provided up to four times the performance of the Catalyst 4500 and 6500
