TCP/IP Connectivity
MAC address —Short for media access control.
Mbps —spelled this way it is short for megabits per second, a unit of measure
for data transfer speed (a megabit is equal to one million bits).
Newer versions of Ethernet, called Gig-E or 1000Base-T support data
transfers of 1 gigabit (1,000 Mbps).
MBps —Spelled this way it is short for megabytes per second.
Multi-homed —more than one network interface (for example, the two SL8500
TCP/IP ports)—this does not imply redundancy.
Netmask —This entry makes the library accessible through a subnet on a
larger network, using a number from 0 to 32; for example, 126.80.70.121/ 23 .

The number 23 in this example is the netmask.
Network masks—also known as a subnet mask or netmask—use bits to
identify the subnetwork, and how many host addresses may access it.
These masks are usually represented by a dotted decimal notation of four
numbers from 0 to 255 separated by periods. For example 255.255.254.0
is a subnet mask.
A shorter form of notation—known as Classless Inter-Domain Routing
(CIDR)—gives the network number followed by a slash (“/”) and the
number of bits in the netmask.
Redundant TCP/IP —relates to dynamic routing or switching from a primary
interface to a secondary interface in the event of a failure on one interface.
This is not supported .
Routing —is the process of moving a packet of data from a source to a
destination. Routing is a key feature in networking because it enables
messages to pass from one device to another device, eventually reach its
target.
Static Routing —routing information in the host system is manually configured
by the system administrator. This is the only routing method supported by the
SL8500.
TCP/IP —Transmission Control Protocol/Internet Protocol
TCP is one of the main protocols in networks that enable two hosts to
establish a connection and exchange streams of data. TCP guarantees
delivery of data and also guarantees that packets are delivered in the
order they were sent.
IP specifies the format of packets and the addressing scheme.
