Improving Network Performance through Enterprise Caching
PDF of this tutorial5. Enterprise Caching Technology Overview
Selective Caching
- Selectively caches data that is frequently used on the link, such as images, JavaScript, and other blocks of data in other protocols
- Maintains mirrored caches in nodes
- Takes two similar packets, caches the repeated pieces, and forwards the unique differences
- Power of caching is extended to all enterprise traffic and not limited to just Web traffic
- Unlike Web caching, the data that is cached does not become stale.
- Reduces traffic flow, and improves throughput efficiency and network performance
Vertical Data Analysis
- Identifies data types with automatic digital signature recognition
- Automatically divides the packet into its various layers
- Highly efficient reduction in size of "header style" information
Adaptive Packet Compression
- Applies an adaptive algorithm to information that was not cached or not a part of the headers
- Unprecedented compression efficiency, resulting in superior performance, unlike legacy compression algorithms
- No added overhead or delay to encrypted or pre-compressed traffic
