Content-aware load balancing using direct routing for VOD streaming service

The number of internet users rapidly increases as the business relies more on the internet and intranet. Accordingly, the traffic on the Internet is increasing dramatically. The workload on the servers is also increasing rapidly so that servers will be easily overloaded for a short time. To overcome the overloading problem of the servers, it is necessary to increase system performance and availability. In the web server cluster environment, it is necessary to implement router that performs routing using TCP information and requested content information, in order to process client's requests in connection with multiple servers. In this paper, designs a load balancer via direct routing that share a virtual service on a single IP address in the Linux system and suggests an efficient load balancing method to improve transmission speed in the web server cluster environment. It will increase performance and scalability with fast packet transfer and removing bottleneck problem by using TCP Splicing and Content-Aware Balancer method.
