Comprehensive practice problems covering OS fundamentals including CPU instructions, memory management, process management, threading, concurrency control, virtual memory, paging, and filesystem operations.
Threads and Concurrency – Thread Creation and Design Patterns
Introduces fundamental concepts of threads including thread creation, management, context switching, and thread design patterns. Explores differences between processes and threads, benefits of multithreading, and challenges in thread-based programming.
TurboEPC – Offloading Mobile Packet Core Control Plane to Programmable Dataplane
TurboEPC redesigns the mobile packet core by offloading a portion of signaling message processing to programmable dataplane switches, alleviating control plane bottlenecks and reducing latency. The approach partitions user state across switches, supports replication for fault tolerance, and implements series and parallel switch designs for scalability. Hardware and software prototypes demonstrate up to 102% throughput increase and 98% latency reduction.
