Routing and Reliability

The expansion of computer networks in the 1980s raised issues in routing, reliability, and information security.

Packet Scheduling and Routing
CSL did cutting-edge work on the scheduling and routing of information packets in computer communication networks.

The Secret Sharing System
This was one of CSL's first results in information security. It protected information against inadvertent damage and covert tampering.

Network Delay Calculus
The powerful sigma-rho delay calculus showed how to derive tight bounds on the end-to-end delay for packet communication networks, depending on the load the network has agreed to carry.
