A major component of the network intelligence universe, WAN optimization appliances accelerate and secure business applications for users across the distributed enterprise to improve user productivity, reduce bandwidth expense and enable key IT initiatives (e.g. Bluecoat ProxySG).
Enterprises need to scale bandwidth and performance, optimizing the networked application architectures for today and tomorrow to support cloud and rich media services globally to all branch offices. For cloud services and SaaS applications - which rely on HTTP and SSL delivery - you need scalable optimization technologies that can asymmetrically accelerate HTTP and SSL and secure client-side certificate handling in way that is also reliable and cost effective.
Growing Complexity Challenges Reliability and Budgets
The growing complexity to create fault-tolerant WAN optimization architectures in the network core is driving up CAPEX and OPEX prohibitively. Core WAN optimization appliances benefit most from this optimization in the form of simplified deployment configuration, robust load balancing between multiple appliances, multi-layered fault tolerance and policy based traffic redirection.
Optimize with Intelligent Load Balancing and Bypass Technology
Part of the VSS Network Intelligence Optimization System, the Protector Series™ performs hardware-based traffic filtering, active inline bypass, and redirection. The Protector family of active vNodes is designed to redirect network traffic inline, intelligently load balance and forward only the traffic of interest to multiple WAN optimization appliances inline.
With VSS systems, you can connect multiple WAN optimization appliances inline to a Protector system incrementally or immediately, for inline configurations. The Protector Series utilize the VSS unique IntelliScale Architecture, delivering a never-seen-before level of network availability, flexibility, and scalability when deploying inline WAN optimization. The Protector Series can be combined to optimize other inline appliances such as firewalls, intrusion prevention systems, and web gateways.
Why Deploy VSS with WAN Optimization:
- Simplify WAN optimization appliance deployment, transparently inline without the need for more complex 3rd Party protocols like WCCP
- Achieve high availability with configurable level of redundancy for WAN optimization appliances inline, so that failure of one appliance doesn't result in a network outage or lapse in security
- Optimize fault tolerance support - configure policy to automatically bypass a failed WAN optimization appliance and send network traffic to a backup appliance, or opt to stop network traffic
- Increase WAN optimization performance and throughput with load balancing, e.g. optimize a 10G link by load balancing to multiple 1G appliances
- Perform maintenance on inline appliances without impacting business applications; automatically redirect traffic during updates or maintenance so that inline appliances can be inserted and removed without application or network downtime
