OKC
Opportunistic Key Caching. OKC is a technique available for authentication between multiple APs in a network
where those APs are under common administrative control. Using OKC, a station roaming to any AP in the
network will not have to complete a full authentication exchange, but will instead just perform the 4-way
handshake to establish transient encryption keys.
onboarding
The process of preparing a device for use on an enterprise network, by creating the appropriate access
credentials and setting up the network connection parameters.
OpenFlow
OpenFlow is an open communications interface between control plane and the forwarding layers of a
network.
OpenFlow agent
OpenFlow agent. OpenFlow is a software module in Software-Defined Networking (SDN) that allows the
abstraction of any legacy network element, so that it can be integrated and managed by the SDN controller.
OpenFlow runs on network devices such as switches, routers, wireless controllers, and APs.
Optical wireless
Optical wireless is combined use of conventional radio frequency wireless and optical fiber for
telecommunication. Long-range links are provided by using optical fibers; the links from the long-range
endpoints to end users are accomplished by RF wireless or laser systems. RF wireless at Ultra High
Frequencies and microwave frequencies can carry broadband signals to individual computers at substantial
data speeds.
OSI
Open Systems Interconnection. OSI is a reference model that defines a framework for communication
between the applications in a network.
OSPF
Open Shortest Path First. OSPF is a link-state routing protocol for IP networks. It uses a link-state routing
algorithm and falls into the group of interior routing protocols that operates within a single Autonomous
System (AS).
OSPFv2
Open Shortest Path First version 2. OSPFv2 is the version 2 of the link-state routing protocol, OSPF. See RFC
2328.
OUI
Organizationally Unique Identifier. Synonymous with company ID or vendor ID, an OUI is a 24-bit, globally
unique assigned number, referenced by various standards. The first half of a MAC address is OUI.
OVA
Open Virtualization Archive. OVA contains a compressed installable version of a virtual machine.
