Cloud & Virtualized Networking
Across
- 4. A signal processing technique used in Wi-Fi 6 to direct a wireless signal toward a specific receiving device rather than broadcasting in all directions.
- 6. Protocols & Logic
- 10. The portion of a hierarchical network that comprises the intermediate links between the core network and the small subnetworks at the edge.
- 11. (Network Context) The process of clearing out old, stale entries from an ARP cache or a routing table to free up memory.
- 12. A private, isolated section of a public cloud provider's network where users can launch resources in a virtual network.
- 14. The process in mobile telecommunications where a cellular session is transferred from one base station to another without interruption.
- 15. (Advanced Clue) A routing technique where multiple servers share the same IP, and BGP directs the user to the "closest" node to reduce latency.
- 16. An interface that allows a controller to push configurations down to the physical or virtual switches (e.g., OpenFlow).
- 17. A technology that allows a router to communicate with multiple devices simultaneously rather than in a round-robin sequence.
Down
- 1. A message sent between two devices to check if the link between them is still active and to prevent firewalls from closing the connection.
- 2. An interface that allows a network component to communicate with a higher-level component (like an SDN controller to an application).
- 3. A property of API requests where making the same call multiple times has the same effect as making it once (crucial for network reliability).
- 5. The deviation of the attenuation affecting a signal over certain propagation media, often caused by multipath interference in wireless.
- 7. An Ethernet frame with a payload greater than the standard 1,500 bytes, used to reduce CPU overhead in high-speed data centers.
- 8. & Mobile Complexity
- 9. A framework for overlaying a Layer 2 network on a Layer 3 network, used to extend VLANs across data center boundaries.
- 13. A small-size datum derived from a block of digital data for the purpose of detecting errors that may have been introduced during its transmission.
