NetStar Technologies' Smart Content Delivery Services are designed to prevent unacceptable web site performance problems from arising. Smart Content Delivery Services deliver fast, reliable Web content, rich media and e-commerce transaction processing by marrying the cost benefits of a monitored, redundant, and shared architecture with the performance and stability of high-end carrier class equipment. 

Smart Content Delivery Services technology utilizes three components:

• Load Balancing
• Global Server Load Balancing
• Reverse Proxy Caching

Why Smart Content Delivery Services

• To ensure web site performance is constantly maintained
• Smart Content Delivery Services prevent problems from arising by delivering fast and reliable Web content, rich media and transaction processing 
• Smart Content Delivery Services leverage a highly reliable Global IP Network to create a content management, distribution and global server load balancing solution that improves performance while providing infrastructure-based cost savings
• Smart Content Delivery Services eliminates bottlenecks inherent to the Internet since content is cached globally on multiple Smart Content Delivery servers that reside at the edge of the Internet and on top of a Layer 2/3 infrastructure
• Smart Content Delivery Caching Services -- available in data centers near Internet peering points -- allows delivery of content to the majority of worldwide Internet destinations with superior quality
• Detailed set of health metrics are constantly monitored for each Smart Content Delivery server so the optimal cache server for a user's request is always known
• Smart Content Delivery Services substantially reduce the likelihood of overloaded Web servers and Internet delays by serving content from the most optimal Smart Content Delivery server, located much closer to end users
• Smart Content Delivery Services provide Web site performance that is two to eight times faster, according to internal research, because of ability to off-load content from original servers
• Smart Content Delivery Services manage and distribute rich media and static content to strengthen a company's brand with increased customer loyalty and greater satisfaction

Load Balancing

• Shares traffic among multiple network-connected devices, such are firewalls, web servers, databases, or caches
• Allocates load across a set of devices that perform the same functionality
• Increases performance by distributing load
• Allows customers to scale server architecture easily in order to keep up with growing traffic demands
• Reduces single points of failure, resulting in higher-availability or "always-on" conditions
• Layer 4-7 switch-based server load balancing allows the most flexible options, greatly augmenting the level of complexity of these balancing algorithms

Global Server Load Balancing

• Allows balancing end user load across multiple servers in geographically distributed data centers
• In addition to standard load balancing algorithms, also allows the implementation of location based routing rules
• By utilizing Global Server Load Balancing across multiple data centers, site owners can improve their sites' performance by moving content closer to users, while gaining protection if an equipment failure or natural disaster disables one or more data centers
• Customers are responsible for the synchronization of their Web content on their origin servers behind the load balancing solution
• The Smart Content Delivery solution controls of basic cache and Global Server Load Balancing switch configuration, monitoring, and management

• Content Edge Servers (geographically distributed caches) which allow caching of Web content in remote data centers
• Content Delivery Network (CDN) content can be distributed widely to the network edge on various caching servers, but these solutions cannot provide fault tolerance for the source server 

Reverse-Proxy Caching

Reverse-Proxy Caching increases origin site capacity by: 

• Reducing the cost of scaling Web server architecture
• Offloading static HTTP content delivery duties from original servers, allowing them more capacity for dynamic content display and e-commerce transaction processing
• Minimized the effects of flash crowds (sudden traffic increases) by scaling quickly
• Decreases download time caused by busy origin servers

• Improving the performance of Web server content by storing the information on caches located near peering points
• Improving the latency and quality of stored or live streaming video by processing it through specialized cache devices built to handle high numbers of connections and multiple streams which are located at peering points
• Enhancing Web users' experience by delivering objects with greater speed and efficiency
• Providing new ways to deliver rich, multimedia content to end users, increasing a Web site's return on investment
• Extending the reach of one Web server throughout the world

• "Local Web Cache/Accelerator" -- caches located in the same data center as the origin server with most of the benefits in increased capacity provided to the entire implementation
• "Content Edge Server" -- caches geographically separated from those servers that eliminates the need for extensive management to keep balanced servers' content in sync, and enabling improved performance by placing the content closer to the user's Web browser
