This book is about pricing issues in modern communications networks. Recent technology
advances, combined with the deregulation of the communication market and the
proliferation of the Internet, have created a new and highly competitive environment for
communication service providers. Both technology and economics play a major role in
this new environment. As recent events in the marketplace make clear, the success of a
communication services business is not guaranteed by new technology alone.
Speed of hardware, NICs (network interface cards), operating systems, logging conﬁgurations,
network bandwidth, load balancing and many other factors must also go into benchmark
requirements. One may have two identical server environments with two very different EPS
requirements due to any or all of these and other variables. With consideration of these vari-
ables, EPS can be established for normal and peak usage times.
To fulfill the ever increasing demands of internet based communication network, the
speed of computing as well as the speed of data processing should be high enough
with the transmission medium of enormous potential bandwidth having the vast
amount of information handling capabilities. On the other hand, conventional
electronic technology has already reached its ultimate speed limit (40 Gb/s) through
the limitations of miniaturization of chips and bandwidth limitation, and obviously it
will create data traffic jam in future internet based networking services....
THE recent development of various methods of modulation such as PCM and PPM which exchange
bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A
basis for such a theory is contained in the important papers of Nyquist1 and Hartley2 on this subject. In the
present paper we will extend the theory to include a number of new factors, in particular the effect of noise
in the channel, and the savings possible due to the statistical structure of the original message and due to the
nature of the final destination of the information....
Real Time Digital Signal Processing Adaptive filters are time varying, filter characteristics such as bandwidth and frequency response change with time. Thus the filter coefficients cannot be determined when the filter is implemented. The coefficients of the adaptive filter are adjusted automatically by an adaptive algorithm based on incoming signals. This has the important effect of enabling adaptive filters

The PON (Passive Optical Network over wavelengths) Express 16 is the first transport platform
to use a Passive Optical Network (PON) architecture to break the access bottleneck. Using Dense
Wave Division Multiplexing (DWDM), the PON Express 16 provides cost-effective access to
business parks, campuses, and multi-dwelling unit/multi-tenant units over a shared network
infrastructure without sacrificing security or limiting bandwidth. Up to 16 customers can be
simultaneously connected with each having up to 1Gbps dedicated, symmetrical bandwidth.
Novel generation wireless system is a packet switched wireless system with wide area
coverage and high throughput. It is designed to be cost effective and to provide high spectral
efficiency . The 4th wireless uses Orthogonal Frequency Division Multiplexing, Ultra Wide
Radio Band and millimeter wireless and smart antenna. Highly directive, planar UWB
antennas are gaining more and more attention, as required in many novel and important
ADC’s LoopStar SONET system is designed to enable service providers to easily and economically provide Ethernet business services to enterprise customers looking to increase their bandwidth above current DS1 or DS3 speeds. These systems efficiently transport layer 2 Ethernet service
over SONET while providing the level of redundancy and protection associated with traditional SONET networks. The LoopStar SONET system is designed to be rack or wall mounted for individual and/or multi-tenant business units.
Private SONET networks provide large multi-site enterprise customers and
campuses a simple cost-effective way to interconnect each site or building using
their own fiber, leasing SONET bandwidth or leasing dark fiber. Large enterprise
customers typically have multiple sites in a metro or campus area. In addition
to requiring connectivity to corporate headquarters, many of these sites need
to be interconnected. Since building a physical mesh network can become
quite expensive, enterprise customers require a cost-effective solution that can
interconnect their sites.
network-based services need powerful end-to-end
solutions to effectively and predictably deliver the
differing Quality-of-Service (QoS) requirements
of voice, video, and data applications. Voice, for
example, requires a small but assured amount of
bandwidth, low delay, low jitter and low packet
loss. A data application such as file transfer
protocol (ftp) needs more bandwidth, but can
tolerate the delay & jitter.
The main goal of Grid programming is the study of programming models, tools, and methods that support the effective development of portable and high-performance algorithms and applications on Grid environments. Grid programming will require capabilities and properties beyond that of simple sequential programming or even parallel and distributed programming.
The tremendous growth of the mobile users’ population coupled with the bandwidth requirements of new cellular services is in contrast to the limited spectrum resources that have been allocated for mobile communications. The objective of channel allocation is to assign a required number of channels to each cell such that efficient frequency spectrum utilization is provided and interference effects are minimized.
Wireless multihop networks, also known as packet radio networks and ad hoc networks, hold great promise for providing easy to use mobile services for many applications, especially military and disaster relief communications. Such networks can provide robust communication, be rapidly deployed, and respond quickly in dynamic environments. However, effectively deploying and utilizing such networks poses many technical challenges. One such challenge is to make effective use of the limited channel bandwidth....
Although FTTP is receiving a great deal of attention for delivering today’s
bandwidth-hungry triple-play services to the home, many service providers are
opting for a fiber-to-the-node (FTTN) access solution. FTTN takes advantage of
existing copper infrastructure to provide a cost effective alternative – and ADC
has developed an entire portfolio of FTTN service delivery solutions.
We show experiments for on-line convergence to a
global partitioning solution for sharing the database
buffer pool, storage cache, and disk bandwidth in dif-
ferent application conﬁgurations. We compare our ap-
proach to two baseline approaches, which optimize ei-
ther the memory partitioning, or the disk partitioning, as
well as combinations of these approaches without global
coordination. We show that for most application con-
ﬁgurations, our computed model effectively prunes most
of the search space, even without any additional tuning
through experimental sampling.
PG-Plus® is a cost-effective subscriber carrier system that derives 2, 4, or 6 lines from a single
copper pair. ADC’s proven HDSL transmission technology provides reach 20% beyond that of
traditional Digital Added Main Line (DAML) solutions.
PG-Plus installs in minutes due to line powering and its plug-and-play design. Its unique

testability and network management all from the same platform.
Access to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation.
