The H.323 standard is a cornerstone technology for the transmission of real-time
audio, video, and data communications over packet-based networks. It specifies
the components, protocols, and procedures providing multimedia
communication over packet-based networks (see Figure 1). Packet-based
networks include IP–based (including the Internet) or Internet packet exchange
(IPX)–based local-area networks (LANs), enterprise networks (ENs),
metropolitan-area networks (MANs), and wide-area networks (WANs). H.323
can be applied in a variety of mechanisms—audio only (IP telephony); audio and
video (videotelephony); audio and data; and audio, video and data. H.323 can
also be applied to multipoint-multimedia communications. H.323 provides
myriad services and, therefore, can...

The DS1 Loop Extender (DLX) module is used to extend a DS1
up to 655 feet to a digital cross-connect (DSX-1). The DLX
receives a non-return to zero (NRZ) 1.544 Mbps signal from the
DS3 Soneplex multiplexer module, converts the NRZ signal to a
bipolar DS1 signal and transmits a DS1 signal that meets the
industry standard DSX-1 template boundaries as defined by TR-
NWT-000499.

ARP performs IP address-to-Media Access Control (MAC) address resolution for
outgoing packets. As each outgoing IP datagram is encapsulated in a frame, source
and destination media access control addresses must be added. Determining the
destination media access control address for each frame is the responsibility of
ARP.

mp3 collections, gargantuan software
programs, and multimegabyte video files
have left PC owners scrambling for free
storage space. The best solution for most
PC users is to buy and install a new hard
disk. Fortunately, now is a great time to
buy: Drives are bigger, faster, and cheaper
than ever. (For more on the recent crop
of drives, see “Livin’ Large” at www.

A cable connection is fast—sometimes. The many dif-
ferent types of DSL are zippy, too, but the installation
hassles they sometimes entail are legendary. Then there
are the dark horse candidates: satellite and wireless.
These offer quick downloads, but who knows what’ll
happen when sunspot activity picks up or some other
atmospheric phenomenon interferes? Finally, there’s
the venerable dial-up modem. It’s definitely not speedy,
but it isn’t too old to be taught a few new tricks.

The Internet Key Exchange (IKE) protocol, described in RFC 2409, is a key
management protocol standard which is used in conjunction with the IPsec
standard. IPsec can be configured without IKE, but IKE enhances IPsec by
providing additional features, flexibility, and ease of configuration for the IPsec
standard.
As mentioned in the T_IPsec chapter, IPsec security associations (SAs) must exist
in order for IPsec to protect network traffic. IKE manages those SAs on behalf of
IPsec, and automatically negotiates protection policies between IPsec peers. ...

During the course of a typical day—if there is such a thing as a typical day—network consultants are bombarded
with questions coming from all directions. These questions come from customers, peers, sales and marketing
teams, network administrators, and so on, and the list seems neverending at times. Network consultants, designers,
engineers, managers, and so on have developed an instinct over time and sometimes cringe or develop other
nervous habits when the phrase, You got a second? is uttered.
To the uninitiated, this question seems innocent enough, but after a while they, too, develop the same cringe or
nervous habit. ...
