Engineering the interactions among all these nodes will become increasingly challenging. This BOF is aimed at initiating discussion for developing standards for = a general purpose recording system for Internet interaction engineering. = Such a recording system must meet important scalability challenges. One scalability challenge is recording computations that involve multitudes = of interconnected devices each with very limited storage and processing capabilities. To accommodate these devices, recording must be = space-time efficient, support events, provide great flexibility in what is to be recorded, and allow recordings to be stored remotely from the device = that created them. Another scalability challenge is recording computations = that involve servers with extensive storage and processing capabilities. To accommodate these servers, recording must, in addition, be able to efficiently and flexibly structure large recordings created on these = servers and to integrate with application services, e.g., Web Services = Architecture. Recording computation is a means of reifying what has happened so far. = It can be particularly useful when computations are not easily repeatable = due to the nature of the computation involved, e.g., indeterminacy, = scalability, security, etc. For example, it can provide information what happens = during or after computations without giving up control of the computing = devices, as is required by traditional tracing and debugging tools. Recording computation that spans several Internet nodes can be linked across = messages between those nodes to provide means for navigating what is happening. =20 A general purpose recording system can become an important tool for = Internet interaction engineering analysis (e.g., debugging, replaying, etc.) and education. =20--- End Message ---
