With this technology, Citrix NetScaler breaks the dependency between application requests and the transport layer to optimally fulfill every end-user's
request. This unique ability to handle individual application requests and responses enables application-level protection and infrastructure
optimization not afforded by other technologies or solutions.
|
- Enables continuous application availability in the presence of traffic surges and malicious attacks
- Boosts server capacity, decreases bandwidth consumption and reduces complexity to significantly lower the total cost of operations
- Provides wire-speed capacity to fully secure the delivery of web applications
As a result, Request Switching technology allows Citrix NetScaler customers to secure 100% of their application content, continuously serve users, and
reduce total cost of operations, all without diminishing their end-user experience.
How Does Request Switching Work?
|
Request Switching dramatically improves the throughput and scalability of Internet application infrastructure by decoupling each
application request/response flow from the underlying transport – ensuring the most efficient use of transport protocols and resources, even in
a scenario where all of the content is encrypted or compressed. By managing the complete lifecycle of the request/response transaction, Citrix NetScaler
is uniquely equipped to direct and control application requests most efficiently, from the customer to the server and back again.
Request Switching includes the following
sophisticated traffic management techniques:
|
- Offloads transport processing from servers and caches
- Analyzes and optimizes every server response
- Provides adaptive regulation of request flow without transaction loss
- Keeps client TCP connections alive to speed response times
- Multiplexes and de-multiplexes application level requests to maximize server efficiency
Through its high performance processing techniques, Request Switching technology optimizes the use of standard Internet protocols by
multiplexing requests from millions of users to a few servers via persistent connections between clients and servers (despite competitor claims,
no competing technology can fully exploit HTTP 1.1 persistent connections like Citrix NetScaler). Request Switching technology adjusts the parameters
associated with transport protocols, allowing the servers to quickly adapt to the capacity of the network. This results in data being transmitted
at a higher rate, improving the user response time. And by offloading the TCP processing onto the Citrix NetScaler system, server side resources are
carefully optimized to achieve high throughput, low latency and high availability.
Citrix NetScaler has built this revolutionary technology into its products at the deepest levels of processing, providing enterprises, e-businesses
and service providers with unparalleled web application protection, unprecedented performance and secure delivery—all at wire speed—in one
complete solution.

Citrix NetScaler's patented Request Switching technology is the foundation for a new breed of web application infrastructure explicitly designed to
ensure the cost-effective, continuous, secure delivery of web applications. Based on pioneering research in network optimization, Request
Switching technology handles web application traffic in the most efficient way possible - by analyzing, securing and directing incoming traffic at
the application request level - enabling fine-grain traffic direction, protection and control.
