SNMP
(Simple Network Management Protocol) A standard protocol that regulates network management over the Internet.
SNMP uses TCP/IP to communicate with a management platform, and offers a standard set of commands that make
multi-vendor operability possible. SNMP uses a standard set of definitions, known as a MIB (Management
Information Base), which can be supplemented with enterprise-specific extensions. See also,
Socket
A communication path between two computer programs, not necessarily running on the same machine. Sockets are
managed by a "socket device driver" that establishes network connections, as needed. Programs that communicate
through sockets need not know anything about how the network functions.
Solution Provider
Vendors are considered to be solution providers when they provide products and/or services that meet their customer's
specific needs. Normally, a solution provider is offering a solution that isn't readily available on the open market. For
example, NOMADIX™ is a solution provider to its customers (broadband network service providers), and those
customers are solution providers to their end users (network subscribers).
SSID
(Service Set Identifier) A 32-character unique identifier attached to the header of packets sent over a
as a password when a mobile device tries to connect to the BSS. The SSID differentiates one
all access points and all devices attempting to connect to a specific
be permitted to join the BSS unless it can provide the unique SSID. Because an SSID can be "sniffed" in plain text
from a packet it does not supply any security to the network. An SSID is also referred to as a "network name" because
essentially it is a name that identifies a wireless network.
SSL
(Secure Sockets Layer) A protocol developed by Netscape for transmitting private documents via the Internet. SSL
works by using a private key to encrypt data that is transferred over the SSL connection. Both Netscape Navigator and
Internet Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as
credit card numbers. See also, Protocol.
Static IP Address
An IP address that is assigned to a computing device permanently (or until the user changes it manually), unlike a
dynamic IP address which is assigned to a device temporarily by the DHCP server. See also, DHCP,
Dynamic IP Address.
STP
(Spanning Tree Protocol) A link management protocol that is part of the IEEE 802.1 standard for media access control
bridges. Using the spanning tree algorithm, STP provides path redundancy while preventing undesirable loops in a
network that are created by multiple active paths between stations. Loops occur when there are alternate routes
between hosts. To establish path redundancy, STP creates a tree that spans all of the switches in an extended network,
forcing redundant paths into a standby (or blocked) state. STP allows only one active path at a time between any two
network devices (this prevents the loops) but establishes the redundant links as a backup if the initial link should fail.
If STP costs change, or if one network segment in the STP becomes unreachable, the spanning tree algorithm
reconfigures the spanning tree topology and reestablishes the link by activating the standby path. Without spanning
tree in place, it is possible that both connections may be simultaneously "live," which could result in an endless loop of
traffic on the LAN.
Subnet
A portion of a network, which may be a physically independent network segment, which shares a network address
with other portions of the network and is distinguished by a unique subnet address. In general, a subnet is to a network
what a network is to the Internet.
