Backup Link Optimization

As accessing business applications hosted centrally is key to day-to-day activity of employees, access link should be redundant. Moreover, due to xDSL eligibility limitations, an enterprise may need to aggregate the bandwidth of multiple links.

But managing a backup link is becoming an increasing difficult task:

• ISDN links have become too expensive and their bandwidth is now too low compared to xDSL main links.
• Having a backup link used only when the main link fails is a waste of bandwidth
• Buying dual access links from the same provider can lead to severe outages in case they are both connected to the same Point-of-Presence (PoP)
• Buying dual access links from different Service Providers can lead to very complex routing management

In order to solve these issues, Streamcore Branch Office solutions provide automated control of application delivery over branch offices with dual access links. A suite of control features allow for more efficient management of dual access links:

• Balance traffic exchanged between StreamGroomers over the two access links
• Activate encryption to use the Internet as a back-up link
• Detect the failure of a main access and automatically adapt the QoS policy and bandwidth management allocation for the new data rate
