NETWORKING TRENDS :)

  Trend: Faster Media

One Gbps over 4-pair UTP-5 up to 100 m

10G being discussed.

Was 1 Mbps (1Base-5) in 1984.

Dense Wavelength Division Multiplexing (DWDM)

64×OC-192 = 0.6 Tbps

OC-768 = 40 Gbps over a 1l to 65 km [Alcatel98]

400 Gbps using 80l products.

Was 100 Mbps (FDDI) in 1993.

11 Mbps in-building wireless networks

Was 1 Mbps (IEEE 802.11) in 1998.

2.5 Gbps to 5km using light in open air

               Trend: All-Layer Routing
Old: All packets followed the same path, stood in the
same FIFO queue. Path based on Destination IP
Address.
New: Buffering, Queueing, Scheduling, and path
based on Destination IP address, Source IP address,
TCP Ports, Type of Service, ...
