REVIEW) — The rapid proliferation of network operation centers and
r

peering points has created new demands and challenges for service
r

providers. Increasing numbers of users and bandwidth-intensive
r

applications have put huge strains on networks, creating a growing
r

market for solutions that enable businesses and service providers to
r

ensure reliable performance of enterprise, e-commerce and e-business
r

applications; increase network efficiency; and enable the convergence
r

of data, voice and video traffic.
r

r

The combined impact of such new
r

applications is that network performance suffers. At best, performance
r

is inconsistent and unpredictable, and at worst, it is consistently
r

slow and frustrating, which impacts productivity and, in the case of
r

e-commerce, profitability.
r

r

The common response from many enterprises
r

and service providers is simply to increase bandwidth. Network managers
r

spend large portions of their budgets on bandwidth upgrades in attempts
r

to solve performance problems. Usually their efforts are in vain,
r

because traffic and control problems normally persist.
r

r

Increased use of intensive applications
r

results in an unending cycle of more traffic, more unmanaged congestion
r

and bandwidth bottlenecks as new bandwidth connections become
r

saturated. Increased bandwidth also always imposes a set-up cost.
r

Enlarging bandwidth pipes always increases costs, and such costs are
r

always recurring. Continually increasing bandwidth can thereby be
r

construed as a cyclical model with limited benefits. In networks
r

overwhelmed by increasing traffic and unmanaged congestion, application
r

performance and company productivity will persistently be undermined,
r

even after bandwidth upgrades.
r

r

The challenge to enterprises and service
r

providers therefore is to exercise more visibility into, and control
r

over, bandwidth allocation and utilization within their data centers.
r

In terms of the network services, service providers need to improve and
r

protect the performance of their clients’ urgent and critical business
r

applications. They need to pace important but less urgent traffic. They
r

need to provision bandwidth for streaming applications to ensure smooth
r

reception. And lastly, service providers need to compress traffic so
r

that more data can fit through increasingly constrained links. Traffic
r

optimization and control solutions can address all these requirements
r

by ensuring the efficient routing of data and through the
r

implementation of policy-based bandwidth usage.
r

r

Good traffic optimization systems allow
r

service providers to gain visibility, control bandwidth and compress
r

traffic. A solution should inform network administrators precisely what
r

applications traverse the network, what portion of the network they
r

consume, how well they perform, and where delays originate. A solution
r

should also offer policy-based bandwidth allocation to boost or curb
r

application performance over network connections. Flexible policies
r

protect critical applications, pace greedy traffic, limit recreational
r

usage, and block malicious traffic. Finally, traffic optimization
r

should enable more data to flow through constrained links, freeing
r

bandwidth for the critical applications that need it.
r

r

Traffic optimization solution developer Packeteer (packeteer.com)
r

says its technology can solve all those problems for a hosting company.
r

Packeteer offers a comprehensive set of solutions that provide
r

visibility, control, compression, and management of Internet-enabled
r

business applications and managed application services. These solutions
r

- which include PacketSeeker PacketShaper, PacketShaper Xpress,
r

ReportCenter, and PolicyCenter – enable service providers to offer a
r

platform for delivering application-intelligent network services that
r

control quality of service and expand revenue opportunities.
r

r

For businesses, these solutions optimize
r

use of network resources, and align application performance with
r

business priorities. Packeteer delivers its application traffic
r

management system via intelligent appliances at the local area network
r

and wide area network interface. This helps enterprises maximize IT
r

investments by aligning network applications and resources with
r

business needs, providing significant cost savings in the process. The
r

Packeteer system protects and accelerates key business applications and
r

controls malicious, recreational and other non-business traffic.
r

r

Packeteer’s solutions automatically
r

detect more than 400 applications running on an enterprise WAN and
r

allow users to set policies and partitions to ensure that critical
r

application get the network resources they need to perform optimally.
r

With its multi-algorithm compression, Packeteer also ensures that an
r

algorithm to enhance network performance compresses multiple traffic
r

types. This allows users to obtain 10 times the compression on some
r

traffic types.
r

r

IDC (idc.com)
r

is quite impressed with the technology. Late in May 2004, the research
r

firm showed that Packeteer had almost four times the market share of
r

its next closest competitor.
r

r

“WAN managers and IT architects are under
r

pressure to cost-effectively manage bandwidth costs while improving
r

application performance,” noted IDC analyst Stephen Elliot. “Adding
r

additional bandwidth to improve WAN application performance is the
r

wrong approach as it does not provide cost efficiencies and utilization
r

improvements. Packeteer has been and continues to be the major dominant
r

vendor in this market.”
r

r

Indeed, in a recent case study, a Fortune
r

1000 company that was initially spending over $1 million a year in
r

bandwidth and was experiencing bottlenecks was able to able to save
r

$600,000 in bandwidth costs and lower connectivity demands with a
r

$200,000 investment in Packeteer technology.
r

r

This is a powerful example of the
r

cost-savings that application traffic management systems can exact for
r

large businesses and service providers with comparable bandwidth
r

requirements.
