IP net management could get easier

IP net management could get easier
IP Flow Information Export (IPFIX), expected to be in final draft by early next year, defines a method for routers and switches to export traffic-flow data to management systems. If adopted, the export standard would be included in network gear from Cisco, Nortel, Riverstone Networks and others. IPFIX-compliant management products then would be able to collect and analyze the traffic-flow data and correlate it with other network and application performance metrics in a management console.

ISPs reel from P2P bandwidth hogs

ISPs reel from P2P bandwidth hogs
Now ISPs say that as much as 60 percent of data traffic zipping around their networks is in the form of large music, movies and software files. For a large ISP, experts say, the bandwidth costs needed to accommodate the traffic could run into the millions, if not tens of millions of dollars per year.

Cable Modem Traffic Jam

Cable Modem Traffic Jam
But, these days, earlier converts to broadband are noticing something different. They are seeing their Internet access rates slow down, instead of speed up. They are sitting in a cable modem traffic jam. In fact, today, a 56K dial-up modem can at times be faster than a cable modem and access can be more reliable, see also Slashdot

Bandwidth Constraints Begin to Worry Schools

Bandwidth Constraints Begin to Worry Schools
Those who are responsible for setting up and maintaining schools' Internet connections say that as more teachers embrace technology in the classroom, schools are reaching the limits of what their network infrastructure can handle -- which in turn may limit the types of applications educators can take advantage of for teaching and administrative tasks.

Some users shift control from hosters to Content Delivery Networks (CDNs)

Some users shift control from hosters to Content Delivery Networks (CDNs)
CDNs deliver content from geographically dispersed servers (Akamai has 8,000) that sit on the edge of various networks (473 in Akamai's case). Not all CDNs are as big as Akamai, however, and there is the issue of how to deliver content over disparate CDNs, a concept known as peering.
