Q: How can you maintain your current network infrastructure while optimizing broadband services?

A: By using the Arbor eSeries solution for intelligent bandwidth management.

Network service providers will always need to add capacity and upgrade their access networks from time to time. What’s important is to be sure this is done for the right reason—namely, subscriber growth. All too often, however, capacity upgrades are made for the wrong reason—specifically, an escalation in bandwidth demand that is out of proportion to subscriber growth.

This disproportionate demand for bandwidth is often due to unattended applications, such as peer-to-peer (P2P) and streaming video. Such bandwidth-hungry applications can consume the bulk of available network capacity and affect the performance of mainstream interactive applications, such as Web browsing and e-mail. With no effective bandwidth management, providers run the risk of continually over-provisioning their networks without achieving the expected performance improvement.

Manage Bandwidth Demand and Network Costs
With the subscriber and application intelligence that the Arbor eSeries solution delivers, you can maximize your existing network capacity and avoid adding costly infrastructure until it’s truly warranted. You can proactively manage bandwidth demand and prioritize it according to how and when it’s used, and by whom. By so doing, you can fully optimize network performance in off-peak and peak periods.

• Scale networks to support growing numbers of subscribers and the bandwidth they require.
• Remove select circuits costing hundreds of thousands of dollars per month.
• Prioritize and control network applications to improve the user experience.
• Deliver a fast, reliable broadband network service, day in and day out.
• Ensure network bandwidth is divided fairly among all users all the time.

Optimize Network Utilization and Broadband Services
The intelligent bandwidth management capabilities of the eSeries stem from its unique ability to measure network traffic by application, activity and subscriber. As a result, the eSeries provides the network visibility and control to meet the following dual objectives:

• Reduced costs through improved network utilization, resulting in an infrastructure that supports more subscribers while using the same capacity.
• Improved broadband services through traffic prioritization, dynamic quality of service (QoS) and real-time bandwidth control to satisfy user requirements, reduce churn and offer differentiated services in an increasingly competitive market.

The eSeries delivers the full advantages of bandwidth management in a cost-effective platform that is easy to deploy and manage. A proven solution deployed in broadband networks worldwide, the eSeries is managing bandwidth for service providers supporting up to millions of active and satisfied subscribers.
