Study Notes
Redes IP (I) - Traceroute y Ping
-
Traceroute y ping: Tools used to diagnose network issues. Traceroute maps the route a packet takes to reach a destination, identifying intermediate routers. Ping tests connectivity with a destination, providing information about latency.
-
Traceroute Operation: Sends packets with progressively decreasing Time To Live (TTL) values. Each router, upon receiving a packet, decrements the TTL. If the TTL reaches zero, the router discards the packet and sends an ICMP TTL expired message back to the sender. This allows tracing the path.
-
Traceroute Example: Shows the sequence of routers involved in a traceroute to a specific destination, along with the time taken at each hop.
-
Ping Operation: Sends ICMP echo request packets to a destination. The destination responds with an ICMP echo reply packet, providing a measure of latency.
-
Ping Example: Shows how pinging a specific destination indicates connectivity and latency.
-
ICMP (Internet Control Message Protocol): Protocol used for error reporting and network information in IP networks. Both traceroute and ping utilize ICMP messages to achieve their functionality.
-
Network Devices: Show diagrams of routers (e.g., R1, R2) and computers (e.g., A, B) linked to represent network setups involved with traceroute and ping examples.
-
Tables Summary: Examples of tables illustrating how devices exchange network information and routing entries. These tables highlight ARP, and routing information necessary for proper network functionality.
-
Sequence of Events: Detailed diagrams depict the order in which network messages are exchanged between devices in a ping or traceroute scenario.
Cronograma and Timing Details
- Timing: The time taken from sending to receiving and responding within a network.
- Diagram Explanation: Shows how devices in the scenario (Router, host) communicate to display results of traceroute and ping.
- Timestamps: Timing details showing how time values/time between events measure latency and packet travel.
- Messages: Explains ICMP messages (Echo Request/Reply) role in confirming communication.
Protocol Breakdown
- Protocols for Messages: Information on ICMP protocol involved in ping communication and the messages involved (e.g., echo request and echo reply), indicating they are crucial for network communication.
