ANDA Plays Ethernet Watchdog
EtherProbe, as ANDA is calling the new systems, was launched this week to coincide with Light Reading's Ethernet Expo: Europe 2009 in London. ANDA will continue to sell its normal EtherReach boxes as well. (See ANDA Launches EtherProbe .)
EtherProbe checks traffic at Layer 2 and Layer 3, looking for potential signs of degradation so that problems can be corrected before the end user -- the VoIP or video consumer, especially -- notices any problem.
By having one of the devices at the customer premises and another at the central office, carriers can watch traffic on a particular Ethernet virtual circuit or a particular network hop. On the customer premises side, the carrier saves some money by not having to install a probe and a demarcation box separately.
Where EtherProbe gets interesting is in the case of guaranteed service levels. If measureable quantities, such as the delay on a VoIP call, reach certain thresholds chosen by the carrier, EtherProbe can tell the network to take action, by switching to an alternate route, for instance.
That means service providers could offer agreements for guaranteed latency or delay on certain services. Ethernet providers are moving towards that kind of "Carrier Ethernet 2.0" model, which involves services more sophisticated than point-to-point connectivity. ANDA itself loves the term, as you can see in this video from last August:
The key is that EtherProbe does its monitoring continually, rather than occasionally checking the line as some probes do. "There are a lot of drawbacks in the way the methodology is being used today," says Greg Gum, ANDA's vice president of marketing.
ANDA claims that EtherProbe is able to do this monitoring without any noticeable effect on the bandwidth. That's a combination of the device's inherently low overhead and the algorithms ANDA has developed, Gum says.
EtherProbe can be bought as a new box or as a software upgrade to EtherReach.
