WSRP（Web Services for Remote Portals）：WebサービスをGUIで組み合わせるWSRP。Webアプリケーションやコンテンツをポートレットとして扱えるようにし、マウスなどで操作するGUI部品を使って画面にポートレットを配置するだけでポータル構築を可能にするというもの。各ポートレットをプラグ＆プレイで組み合わせることができ、アプリケーション固有の整合作業や手作業での調整は必要なくなる。
JSR168（JSR：Java Specification Request）
RBOC：Regional Bell Operating Companies (8社あり)米国の地域電話サービス会社。
Access Service (provided by Windows NT) ：service provided
by Windows NT which allows most of the services which would
be available on a network to be accessed over a modem link.
The service includes support for dialup and logon, and then
presents the same network interface as the normal network
drivers (albeit slightly slower!).
RAS：Remote Access Server - PCなどからISDNや電話回線を介して遠隔地のLANに接続するリモート・アクセスのためのLAN側の装置。
TTPT：Point-to-Point Tunneling Protocol (Microsoft)
Access Control (Ascend) - A system of rules used to move data
from one physical medium to another.
Access Exchange (Ascend) - The Ascend MAX is a system-level
network access unit, with a cage and backplane into which Multiband
or Pipeline cards can be inserted to configure it for various
application requirements. It supports up to 32 host ports or
direct Ethernet connection and up to 8 Mbit/s to the network.
It supports multiple applications, including remote LAN access,
leased line backup and individual videoconferencing units,
as well as connecting videoconference MCUs to the digital dial-up
toll service refers to calls made between two different local
service areas within the same Local Access and Transport Area
(LATA). These calls are often referred to as regional toll
WATS: Wide Area Telephone Service and 800/888 "toll-free
number" service. - WATS is an effective solution for customers
with large-volume outbound calling. 800/888 service provides
added value to organizations who wish to increase their accessibility
to their customers and reduce the expenses of collect calling.
Annual Growth Rate(複合年成長率) - The formula for compounded annual
growth rate: ((last value/first value)^(1/(last year - first
FT1：Fractional T1 - A (usually) 128-, 256-,
384-, 512-, or 768-kbits/s point-to-point digital data communications
channel (which corresponds to 2, 4, 6, 8, or 12 channels of
a T1). The physical circuit is a full 1.544 Mbits/s T1 line
with CSU/DSUs, but only some (that is, a fraction) of the 24
slots are used.
T3：Digital Transmission Rate 3 - A communications
circuit that supports 28 T1s, which is a total of 672 DS-0
channels. Each DS-0 carries 64,000 bits/s of data (which could
also be a digitized voice conversation). The actual bit rate
is 44.736 Mbits/s.
OC-3：Optical Carrier 3 - A SONET rate of 3 *
51.84 = 155.52 megabits per second, which matches STS-3.
DS3：44.736 Megabits per second.- The third DS
level, a framing specification for digital signals
Gateway Protocol 4 - BGP-4 provides a new set of mechanisms
for supporting classless interdomain routing. These mechanisms
include support for advertising an IP prefix and eliminates
the concept of network "class" within BGP. BGP-4 also introduces
mechanisms which allow aggregation of routes, including aggregation
of AS paths. These changes provide support for the proposed
OSPF：Open Shortest-Path First Interior Gateway
Protocol - A link state routing protocol, as opposed to a distance
vector routing protocol. It is one of the Internet standard
Interior Gateway Protocols defined in RFC 1247.
MPLS proposes a network architecture that employs
two main types of routers:
LER (Label Edge Routers) located at the
edge of the network to perform traditional routing function
(layer 3) and for connectivity to user networks
LSR (Label Switching Routers) located
in the core of the network to perform high-performance
Label Switching Routing (layer 2).
MPLS network architecture can in itself increase
core network performance and capacity by a factor of ten over
traditional routing. Furthermore, MPLS networks retain full
compatibility with existing IP based systems and thus protect
