 Banyan switch - Wikipedia, the free encyclopedia
Banyan Switches are complex crossover switches used in electrical or optical switches.
Logical banyan switches are used in logic or signal pathways to crossover switching of signals onto new pathways.
Their complexity depends on the topology of the individual switches in a switch matrix (how wide it is by how many 'plies' or layers of switches it takes), to implement your desired crossover logic.

 Cisco Systems Designing Switched LAN Internetworks
A LAN switch is a device that typically consists of many ports that connect LAN segments (Ethernet and Token Ring) and a high-speed port (such as 100-Mbps Ethernet, Fiber Distributed Data Interface [FDDI], or 155-Mbps ATM).
The fundamental difference between a LAN switch and a router is that the LAN switch operates at Layer 2 of the OSI model and the router operates at Layer 3.
Switched LAN topologies are susceptible to loops, as shown in Figure 12-6.

The multiplex switching is the physical transfer of a cell from an input port to the output port.
Label switching is translation of a connection identifier from one valid at the input port to one valid at the output port.
A minimal signaling path is the one from the bottleneck back to the place where the last data frame which was pushed into the network by the source currently resides.

 Integrated packetized voice and data switching system - Patent 4958341   (Site not responding. Last check: 2007-10-13)
Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024.times.1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module.
The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator.
In accordance with one embodiment of the invention, a packet switch is used for switching voice packet outputs of the data switching modules and a circuit switch, such as the space division switch, is used for switching data packet outputs.

Regeneration allows a firm to create LANs that span very long distances because the data link distance across multiple switches in an Ethernet LAN is almost unlimited because the signal sent from switch to switch is regenerated as a clean signal to the next switch.
Switches in an Ethernet LAN are organized in a hierarchical topology.
A nonblocking switch is a switch with aggregate throughput large enough to handle even their highest possible input load.

The optical nature of the switch provides enormous bandwidth with input/output port rates of the order of Gbits/sec., and the distributed approach is highly modular, creating an easily growable switch.
In medium to large reconfigurable switches, clustering techniques are required for optimizing the connection diagram among modules and routing traffic through the switch.
However, simulation results for a switch of size $81 \times 81$ seem to indicate that the traffic-handling capability scales well with the size of the switch when non-uniformity prevails in the offered traffic, a realistic assumption.

The reason suggested is that otherwise bandwidth is wasted by transmitting fragments of partially dropped packets, which the receiving TCP cannot use.
In fact ATM switches tend to drop cells from multiple packets when the window increases too much, causing TCP to pause for a long time rather than continuing with a reduced window.
Each switch estimates the additional fraction of cells lost if a new call would be routed through the switch.

Nonblocking Minimal Spanning Switch - Needs work from someone knowledgeable about some of the theoretical underpinnings of telephone networks, things like Clos networks in their rearrangeably nonblocking form.
There are other problems but I am not familiar enough with the topic (Flanders is both a region in Belgium and a region spanning three countries...).
there is also a bit, noted on its discussion page, about someone exploring "fifty metres inland" seems to be a verrrry minimal exploration if that measurement is correct.

 SuperStack II Switch Family 10/100/1000 Stackable Switches
The Switch 9300 learns MAC addresses (up to 16,000) on all ports at a address learning rate of 400,000 addresses per second and by default floods frames with unknown destination addresses to all ports assigned to the source frame's VLAN.
SuperStack II Switch 2700 is an Ethernet/ATM workgroup switch with 12 Ethernet ports and 1 ATM port for high-speed backbone connections.
The switch is ideal for workgroups and small departmental LANs that need increased bandwidth across Ethernet ports, and also require a high-speed ATM downlink to an ATM campus backbone now or in the future.

As switched internetworking is taking over as the new wave in campus networks, Cisco Systems has gained a leadership position in implementing switched campus networks using leading-edge products and technology.
The Catalyst 5000 family is flexible enough to function as a wiring closet switch and as a collapsed switch in the data center.
Unlike other ATM switch architectures, however, the shared-memory fabric of the Catalyst 5500 switch allows all the advanced traffic management and other mechanisms of the switch to be implemented not on the interface modules, but on a field-replaceable feature card on the switch module.

This switch disables code in a number of places throughout ntop, code which analyzes specific protocols, but can place additional load on the host.
This switch could be used to run ntop on low-end CPUs or where ntop is acting as a collector (netFlow or sFlow) and the GUI is not required.
