Next-generation firewalls claim to identify application-layer attacks and enforce application-specific policies while delivering top-notch performance, even with advanced security features turned on.

SonicWALL's initial response to results of our SSL decryption tests was "you've got to be kidding - we go way faster than that." Indeed, the vendor's internal tests showed the Supermassive decrypting SSL traffic at rates well into the gigabit range, compared with less than 100 Mbps in some of our tests.

We assessed performance using three sets of tests, covering forwarding rates with mixed HTTP content; rates with static HTTP content, and TCP connection behavior. Two pairs of Spirent Avalanche 3100 GT traffic generator/analyzers, each equipped with two 10G Ethernet interfaces, served as the primary test tool. We connected all devices using an Arista Networks 7124S 10-gigabit Ethernet top-of-rack switch.

Packing 384 10G Ethernet ports into an 11-rack-unit form factor is only the beginning for Arista Networks' DCS-7508 data center core switch.

We assessed the Arista DCS-7508 with tests of performance and power consumption. The performance tests used the Spirent TestCenter test instrument to measure layer-2 and layer-3 unicast throughput and latency; layer-2 and layer-3 multicast throughput and latency; OSPF equal cost multipath (ECMP); N+1 fabric failover; buffering capacity; OSPF routing capacity; and multi-chassis link aggregation (MLAG). All tests used version 4.8.4 of Arista's EOS software and version 3.95 of Spirent TestCenter software.

We assessed the performance of the Palo Alto PA-5060 firewall using three sets of tests, covering rates with mixed content; rates with static content, and TCP connection behavior. Two pairs of Spirent Avalanche 3100 GT traffic generator/analyzers, each equipped with two 10G Ethernet interfaces, served as the primary test tool.

Cisco doesn't just want to sell you switches. It also wants to be your power distribution vendor.

We assessed the Cisco Catalyst 4500 with tests of functionality, performance and Ethernet energy efficiency. The performance tests used the Spirent TestCenter test instrument to measure layer-2 unicast throughput and latency; layer-3 throughput and latency, with separate IPv4 and IPv6 tests; layer-2 multicast throughput and latency; layer-2 MAC address capacity; and in-service software upgrades and downgrades (ISSU/ISSD). All tests used version 03.02.00.2.70 of Cisco’s IOS-XE software (with a .80 release for the ISSU test) and version 3.62 of Spirent TestCenter software.
