Benefits of technology
This patented technology improves upon existing methods by providing an isolated section called Shared Memory Data Storage Critarea Protection (SCA) which controls how many times each piece of hardware device accessing this region has been granted access before they have accessed any other parts or functions within their own network. It prevents damage caused during these procedures while still allowing different devices to communicate securely through communication channels like HTTP protocols over TCP/IP networks. Additionally, SCA allows users to easily configure services across various domains without having to worry about interfering with previous configurations files. Overall, this innovation enhances the functionality and reliability of software systems' networking capabilities.
Problems solved by technology
The technical problem addressed in this patents relates to managing remote internet protocol television networks without compromising their reliance or functionality provided by current systems like TCP connections. Current solutions require manual configurations and administration from operators who manually configure each device's settings before deploying it into an enterprise environment.
