Part $3$: Integration of Concepts

Scenario: A streaming service company is experiencing lag issues. They use $1$Gbps Ethernet $(1000$BASE$-$T$)$ for their LAN and primarily rely on TCP for transmitting video content.

Problem Analysis: Highlight potential issues that might cause lag in the given scenario, considering both Ethernet and transport protocol aspects.

Recommendations: Suggest at least one solution related to Ethernet and one related to the transport protocol to improve the streaming experience for users.

UDP Consideration: Would using UDP be more efficient for video streaming in some scenarios? Provide a brief justification for your answer.
