Introduction

Ethernet Switching Technology

Ethernet Switching Technology dramatically increases the total bandwidth of a network, eliminates
congestion problems inherent with ( CSMA/CD ) protocol, which greatly reduces unnecessary
transmissions.

Switch Technology has revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port ( Full-duplex ), which essentially doubled the bandwidth. Second, by
reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing.
Third, by using the store-and-forward technology’s approach of inspecting each packet to prevent
transmitting corrupt or redundant data, switching eliminates unnecessary transmission. By employing
address-learning, the switch only transfers data to the port it is destined for.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices.
Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto­negotiation and flow-control may require disablement for some networking operations involves legacy
equipment. Disabling the auto-negotiation is accomplished by configuring the speed or duplex of a port.

Ethernet Switching Technology supplies higher performance at costs lower than legacy solutions. Wider
bandwidth, no congestion, and the reduction in traffic are the many reasons why switching is replacing
expensive routers and inefficient hubs for the ultimate networking solution. Switching brings a whole
new way of thinking to networking.

The MIL-S2400 and MIL-S1600 Switches are multi-port Switches that can be used to build high­performance switched workgroup networks. These switches are store-and-forward devices that offer low
latency for high-speed networking. They are targeted at workgroup, department or backbone computing
environment at SME ( small, medium enterprise ) businesses.

Figure 1-1. The MIL-S2400 and MIL-S1600 Switch ( Auto MDI/MDIX )

The MIL-S2400 and MIL-S1600 Switches feature a “store-and-forward “ switching scheme. This allows
the switch to auto-learn and store source address on an 4K-entry MAC address table.
The MIL-S2400 and MIL-S1600 Switches have 16/24 auto-sensing 10/100Base-TX RJ-45 ports plus
one extension slot for ( Optional ) 100Base-FX fiber module enables long-distance connection. The
optional modules support MT-RJ, SC single-mode, ST, MT-RJ, VF-45 multi-mode connectors. The fiber
port can be used to connect to a remote side up to 2 Km ( multi-mode ) or 60Km ( single-mode ).
