TRILL
TRILL (Transparent Interconnection of Lots of Links) is a networking technology that helps large organizations manage their computer networks more efficiently. Think of it as a traffic management system for data centers that helps information flow faster and more reliably. Network engineers use TRILL to replace older methods of connecting computer systems, especially in big data centers where traditional networking approaches might cause slowdowns or reliability issues. It's similar to other networking approaches like Shortest Path Bridging (SPB), and both help make large networks more stable and efficient.
