NMS
Network Management System. A generic term describing most elements of
network management.
Octet
An octet is 8 bits. This term is used in networking, rather than byte, because
some systems have bytes that are not 8 bits long.
OPSEC
Open Platform for Secure Enterprise Connectivity. A level of certification
applicable to products that are deemed compatible with OPSEC standards.
OPSEC-certified products guarantee interoperability at the policy level
between Checkpoint's FireWall-1 and leading security applications. OPSEC
Alliance members cover the broad range of enterprise network security
technologies, including authentication, encryption, content security,
networking infrastructure, application software, and managed service
providers.
OSPF
Open Shortest Path First. Similar to RIP, except that OSPF broadcasts when
a new router is on the network or a route changes. OSPF also considers factors
such as line capacity, delay, and security restrictions, as well as Hop count
when calculating a route. OSPF is a link state, as opposed to distance vector,
routing protocol. It calculates routes based on least hops, speed of
transmission lines, and congestion delays.
OSI
Open Systems Interconnection. A set of international, openly developed and
accepted standards created by the ISO and CCITT (now ITU-T) for data
networking.
