Across
  1. 2. The insertion of non-information bits into data to prevent specific patterns (like flags) from appearing in the payload, ensuring frame synchronization.
  2. 4. A specialized packet sent by a congested router to the source host to signal it to slow down its transmission rate.
  3. 5. A theoretical defense or technology that claims to solve all security problems, often used in networking to critique over-hyped security tools.
  4. 6. A technique where an acknowledgment for a received packet is attached to the next data frame being sent in the opposite direction.
  5. 7. Internals & Behaviors
  6. 8. A denial-of-service attack that exploits the TCP three-way handshake by sending a barrage of initial requests but never responding to the server's acknowledgment.
Down
  1. 1. A mechanism used to improve TCP efficiency by coalescing several small outgoing messages and sending them all at once.
  2. 3. An algorithm that doubles the waiting time between retries after every collision or failure, commonly used in Ethernet and CSMA/CD.
