Computer Networks

A book-shaped table of contents for computer networking, from first principles to production systems: Ethernet through IP, TCP/UDP/QUIC, DNS, the HTTP ecosystem, security, cloud/Kubernetes networking, performance engineering, observability/debugging, and distributed-systems networking — cross-linking existing kubernetes/sre/system-design/tech notes instead of duplicating them.

1 — RPC Systems

The RPC call lifecycle, serialization, and timeouts as the networking concerns underneath every remote procedure call.

2 — Message Brokers

Kafka, RabbitMQ, NATS, and Pulsar as message brokers, and how each handles the networking side of asynchronous messaging.

3 — Event Streaming

Partitions, consumer groups, and delivery guarantees as the mechanics behind event-streaming systems built on top of message brokers.

5 — Cross-Region Communication

Replication, WAN latency, and multi-region design as the networking concerns specific to systems that span regions.
