Frame relay is also a critical technology for the Internet--service providers use it for port aggregation
, backbone switching, and dedicated customer access.
The new PAIX offers the following advantages: 99.999% availability commitment; 24/7 support; proactive network operations centre (NOC) monitoring of system performance; customer ability to monitor traffic stats and sFlow through the Customer One portal; port speeds from 100Mb/s to 10GigE, including multiple 10GigE port aggregation
up to 80GigE; Route Server; public and private peering via VLANs; as well as support for IPv4 and IPv6.
<p>The IEEE draft standards boast a feature called Virtual Ethernet Port Aggregation
(VEPA), an extension to physical and virtual switching designed to eliminate the large number of switching elements that need to be managed in a data center.
Additionally, the IEEE approved the 802.3ad port aggregation
standard in March 2000.
In addition, this new switch family supports port aggregation
, which allows Ethernet ports to be combined to form a single higher speed port - as well as port mirroring, which allows all traffic of a port to be 'mirrored' to another so it can be analyzed.
