PowerNOC Helps Slow Computer Viruses for Wireless ISPs
Packet Rate Limiting tool is now available through PowerNOC.
Orem, Utah (PRWEB via PR Web Direct)
August 19, 2005 -- Computer viruses can be a constant battle for small Wireless
ISPs. If a customer's computer is infected with a computer virus, it can mean
disaster for the ISP's network. It can even shut the Internet down for customers
who don't have viruses. PowerNOC has recently developed a tool that will help
slow these viruses.
When a computer is infected with a virus, it
typically blasts the network with hundreds of tiny packets each second. Wireless
ISPs have it harder then other ISPs like DSL and cable because Wireless ISPs use
equipment that cannot handle the packet rate that wired equipment can. A virus
can usually send packets faster than the wireless equipment can process them,
which can cause a single computer virus to shut down the Internet on an entire
wireless network. One virus can use up all available packets.
Most
Wireless ISPs (sometimes called WISPs) put an outdoor wireless access point on a
high tower. This access point can transmit a wireless Internet signal within a
2-5 mile radius. Customers who want Internet have the ISP come to their home and
put an outdoor radio, which looks like a satellite dish, on their house. An
Ethernet cable is then run from the radio to the inside of the customer's home,
where they connect a computer for Internet access.
PowerNOC has recently
developed a software tool to put on the radio at the customer's home that limits
the amount of packets per second that can be transmitted to the access point.
This is called "Packet Rate Limiting."
PowerNOC is now shipping an
outdoor radio that has this technology built into it. Now, when a computer has a
virus the packet rate limiter will keep the packets transmitted to the access
point within normal limits.
