APN: An Access Point Name (APN) provides access to an external
network. By default, the SIM Card in your terminal is configured
with the APN of your Service Provider. You may want to
configure further APNs if you have arranged with your Service
Provider to use more than one SIM Card.
BGAN Satellite Terminal: Referenced throughout this document as
the Satellite Terminal or “The Terminal,” this device implements
and manages BGAN satellite communications between your
computer and Service Provider’s network.
Class of Service: Class of Service (CoS) assigns a level of priority to
certain types of data traffic, in particular high bandwidth
applications such as video and multimedia. CoS attempts to
maintain a guaranteed throughput level, and minimize error
rates and end to end latency, so providing a higher level of
service than "best effort" protocols.
DNS Server: The Domain Name System (DNS) is an Internet service
that is required because the Internet does not recognize the
text-based Web address or email address that you type into your
Web browser or email application. All or part of a Web address
or an email address is a domain name, and DNS translates this
domain name into an IP address that is recognized by the
Internet.
A DNS Server holds a database of domain names and IP
addresses, so that when you enter a Web address or email
address, you are sent to the correct IP address over the Internet.
Dynamic DNS Server: If you are using dynamic IP addressing,
Inmarsat recommends that you use a dynamic DNS server. A
dynamic DNS server updates the IP address information in
the DNS database each time your IP address changes. A
dynamic DNS server also enables a computer using a
dynamic IP address to use network applications that
normally require a static IP address, for example FTP servers.
