CODES FOR DATA STORAGE WITH QUEUES FOR DATA ACCESS

Users of cloud systems demand that their data be reliably stored and quickly accessible. Cloud providers today strive to meet these demands through over-provisioning: keeping processors ready to go at all times and replicating data over multiple servers. Special erasure codes have been designed and adopted in practice as a more storage-efficient way to provide reliability. We will show how coding reduces download time of large files, in addition to providing reliability against disk failures. For the same total storage used, coding exploits the diversity and parallelism in the system better than today's replication schemes, and hence gives faster download. We will introduce a fork-join queuing framework to model multiple users requesting their data simultaneously, and demonstrate the trade-off between the download time and the amount of storage space. At the end, we will mention several problems that arise in distributed systems when the stored data is large, changing, and expanding.

PHYSICAL-LAYER NETWORK CODING WITH LATTICES

Using ideas from compute-and-forward relaying and lattice coding, we show how wireless fading and interference can be turned from a "bug" to a "feature", yielding an end-to-end physical-layer network coding channel. (Joint work with Chen Feng and Danilo Silva.)
