Review: Wave 2 Wi-Fi delivers dramatic performance boost for home networks
In our testing with a Linksys SoHo router, we found that beamforming and MU-MIMO technologies could transform Wi-Fi networks

You can't see some malware until it's too late. Sophisticated attacks arrive in pieces, each seemingly benign. Once these advanced attacks reassemble, the target is already compromised.
Desktop publishing was the killer app that got me started with Macs.
In this Clear Choice test – Huawei's first public outing in a North American setting – the world's largest telecom vendor took the humble approach, supplying a pretty basic managed layer-2 switch that is a key building block found in every enterprise wiring closet.
Judging by initial appearances, our security testing turned up a ton of vulnerabilities – nearly 150 of them. In reality, however, none represented actual issues in the Huawei switch.
Huge data center, check. Multiple 10G Ethernet pipes, check. Load balancer, check. Firewall? Really? Do network architects need to buy yet another box, and likely take a performance hit?
It takes something different to stand out in the crowded network-attached storage market. How does free, as in free beer and free speech, sound?
Chinese telecom provider Huawei was hardly a household word a few months ago, but it's had lots of negative publicity of late, from an Economist cover story to a 60 Minutes piece.
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.
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.
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 100Mbps in some of our tests.
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.
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.
If you're considering the move to 40/100gigabit Ethernet, here are five things to keep in mind:
Ten-gigabit Ethernet was so last year.
