D-Link today announced a MoCA-based Coax Ethernet Adapter and kit.
The DXN-221 Coax Ethernet Adapter Kit allows the use of existing television coaxial cable to extend an Ethernet connection without the need to install CAT 5/6 cable. The adapters are Multimedia over Coax Alliance (MoCA) certified and will coexist with cable television signals on the same coax.
Internet Protocol version 6, known as IPv6, is an upgrade to the world's most common network addressing scheme, Internet Protocol version 4 (IPv4). The purpose of this post is to provide you with some background information on IPv6 and some simple things that you can do to get acquainted with it.
CopperGate Communications today announced the purchase of the HomePlug AV business from Conexant Systems. CopperGate said it is now the first semiconductor company with home networking technologies supporting all three wire types coax, phone and power.
Having introduced Iperf and Jperf, as well as covering details on TCP throughput tests by adjusting Window Size values, it's time to complete this series with comments on adjusting MSS and Buffer Length values. I'm also going to touch on using the results of Jperf testing to make changes to a PC to improve network performance.
Free and openly available, Iperf is a command line tool useful for measuring network performance. In my last post, I introduced some basic command line instructions to run Iperf between two endpoints and showed how the tool can be used to generate and measure both TCP and UDP performance. This time, I'll discuss Iperf's graphical cousin: Jperf.
The HomePNA Alliance wants us to know that it is still in the fight as an alternative (to Ethernet) networking technology. It today announced HomePNA 3.1 certification of nine new products and the first 320 Mbps chipset reference design from CopperGate.
The newly-certified products include VDSL2 and ADSL2+ residential gateways, Ethernet to coax bridges and a set top box. Companies included 2Wire, D-Link, SMC, SendTek and Scientific Atlanta.
One of the cool things about networks is there are many free tools to work with if you know where to look and how to use them. I've looked at a couple free network tools on this blog so far, including Wireshark and NetMeter. This time, I'm going to take a look at another network tool known as Iperf, a network performance tool used for measuring the bandwidth and the performance of TCP and UDP data flows between two endpoints.
