A Middleware Approach to Achieving Fault Tolerance of Kahn Process Networks on Networks on Chips

Algorithm 1

Sender middleware task per outgoing connector (𝑡: data token, 𝑡_𝑣𝑐: dummy token for virtual connector, 𝑃_𝑅: process identifier of the remote middleware task, 𝑣𝑐: virtual connector tag, 𝑜𝑐: original connector tag).
