Latest Patents

One of Dragan Djurovic's latest patents is titled "Fault tolerance approaches for DNS server failures." This invention provides techniques for handling failures of DNS servers to respond to queries. The DNS resolver is designed to resolve domain names and includes a time-to-live (TTL)-based cache, a negative cache, and a long-term store cache. The TTL-based cache temporarily stores domain names with resolved IP addresses, while the negative cache stores entries indicating domain names that failed to be resolved. The long-term store cache retains resolved domain names indefinitely. This innovative approach reduces delays and network traffic by minimizing the number of DNS query retries when a server is non-responsive.

Another significant patent by Djurovic is the "Chattering line detection system and method." This system allows operators to remotely detect and diagnose a voice-enabled cable modem that has entered a chattering line state. The logic within the modem monitors for pulse dialing activity and excessive hook state or flash events that may indicate a faulty telephone or line. Upon detecting such conditions, the modem reports a fault condition to an external management system via a cable data network, enabling timely intervention.
