Dynamic Load-Balancing DNS: dlbDNS

An attempt to solve the problem of network traffic congestion by adding a dynamic load-balancing feature to the existing DNS.
Future Work

Currently, the gethostbyname system call fails within the BIND code. This problem is avoided by using a configuration file with a list of host and IP addresses. We'd like to find a better solution.

The rating algorithm is still not complete. An algorithm that takes into account the number of processors, CPU and memory utilization would make the rating algorithm more efficient.

At this time, only Linux servers can take part in the dynamic load-balancing scheme, as the rating algorithm uses files in the /proc file structure. A more extensible design is needed.

Developing servers with more

Developing servers with more capacity and capability of handling this traffic is one way to solve the problem; another is to distribute client requests across multiple servers.
