Using Linux's network namespace feature, the job only can access one of the network pipe devices. The other end of the network pipe device is configured to utilize the host's network. By having HTCondor manage the external network pipe device's configuration, we manage every aspect of the job's network. + +Lark's technologies allow for users to specify a desired network policy and the starter to execute the desired configuration. See the developer documentation below for more information about what can be configured. + Personnel responsible: Zhe Zhang, Brian Bockelman +{subsection: PIVOT outreach} + +The PIVOT project is an outreach project based at UNL.
