U
UCS
Cisco Unified Computing System. Represents a radical simplification of traditional network
architecture, reducing the number of devices required to be purchased, cabled, configured,
powered, cooled, secured, and managed. Provides end-to-end optimization for virtual
environments while creating new agility for traditional OS and application stacks in physical
environments.
UCS CIMC
UCS Cisco Integrated Management Controller. Provides a lights-out management (LOM)
interface for Cisco UCS hardware.
UCS USRM
Platform for a very rack-dense USRM deployment that uses virtualization and Cisco UCS
hardware to fit eight virtual USRMs into a single 1 RU Cisco UCS server.
UDP
user datagram protocol. A connectionless protocol, like TCP, that runs on top of IP networks.
Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct
way to send and receive datagrams over an IP network without acknowledgements for
guaranteed delivery.
URL
uniform resource locator. A standardized way of representing different documents, media,
and network services on the World Wide Web. The URL is most commonly referred to as the
Web address for a particular item. For example, the URL, or Web address, for Cisco is
http://www.cisco.com.
USRM
universal session and resource manager.
V
VASP
value added service provider. A generic term for a server that is a part of the DBDS with data
files that contain system information and configuration information. VASP data does not
directly involve audio and video program services. Setting up a VASP enables the DNCS to
recognize the server and establishes a path for them to communicate with each other.
VCS
virtual channel service. A service in the Program and System Information Protocol (PSIP), that
provides a list of all the channels that are or will be on line, plus their attributes such as
channel name and channel number. This information allows a receiver to tune and locate the
particular service being broadcast.
