Software dataplane verification

Towards a Programmable Dataplane

Software Verification

When a technology reaches a higher level of maturity, its development begins to diversify and to differentiate. In 1885 engineers were happy to build the first car powered by a gasoline engine. Today we see a whole spectrum of vehicles ranging from city cars, limousines, off-road vehicles, sports cars, buses, trucks, etc., that share some basic technologies but greatly differ in details. Softwa...

A Look at Intel’s Dataplane Development Kit

The increased performance and cost-efficiency of modern multi-core architectures allows for packet processing implemented in software instead of using dedicated hardware. Such solutions provide large flexibility as features can be added at any time. The drawback of such systems are bottlenecks which appear during the processing of packets at line rate up to 10 Gbit/s. Hence, specialized high-sp...

Automated Incremental Software Verification

Software continuously evolves to meet rapidly changing human needs. Each evolved transformation of a program is expected to preserve important correctness and security properties. Aiming to assure program correctness after a change, formal verification techniques, such as Software Model Checking, have recently benefited from fully automated solutions based on symbolic reasoning and abstraction....

Reuse in Software Verification

A major obstacle facing adoption of formal software verification is the difficulty to track changes in the target code and to accomodate them in specifications and in verification arguments. We introduce abstract method calls, a new verification rule for method calls that can be used in most contract-based verification settings. By combining abstract method calls, structured reuse in specificat...
