Meeting summary --------------- * LINK: https://wiki.opendaylight.org/view/Group_Policy:Sub-Groups:MODEL#Team_Meeting (alagalah_, 17:05:56) * white board diagram of 3-tier to JSON (tbachman, 17:06:22) * alagalah created JSON of 3-tier model (tbachman, 17:07:29) * Regarding action of 3 tier app softcopy and JSON generation find information here: (alagalah, 17:07:48) * ACTION: https://drive.google.com/folderview?id=0BztNICcppsJKY0tMRl8tVlBQN2s&usp=sharing (alagalah, 17:07:53) * work in progressw (alagalah, 17:08:24) * Create power point of 3-tier (tbachman, 17:08:38) * work in progress -- task takes time (tbachman, 17:08:50) * action from last meeting: alagalah to instead of writing whitepaper or annotating the UML to write a PPT with animations that describes the UML model with annotations. (alagalah, 17:08:55) * WIP : blocked on time (alagalah, 17:09:01) * Action: dvorkinista to restruct model in structure, definition use - has not had time. (alagalah, 17:09:24) * no update, Mike at OS summit (alagalah, 17:09:31) * Action: alagalah regXboi edwarnicke to discuss service chaining, specifically their datastore/subscription requirements and how they are planning on addressing this with MD-SAL etc (alagalah, 17:09:44) * Action Items (though look to other topics on resolution -- didn't get topics right at first) (tbachman, 17:10:16) * ACTION: alagalah to schedule meeting with edwarnicke and regxboi (possibly ChrisPrice) to discuss Action: alagalah regXboi edwarnicke to discuss service chaining, specifically their datastore/subscription requirements and how they are planning on addressing this with MD-SAL etc (alagalah, 17:10:35) * Action: alagalah meeting with Uyen, Rex, Dave Lenrow, regXboi to discuss Use-Case -> UML -> JSON "conversion" ... 14:30 Pac Fri May9 (alagalah, 17:11:29) * meetings have been ongoing -- Unified communications use case with proactive flows. Team has been working on mapping use case to the model (tbachman, 17:12:10) * Microsoft Lync uses many ports, so the question has been of how to provide information for classifier so that renderer can install flows between session peers. (tbachman, 17:13:21) * plan is to manage call setup of 200+ per second (tbachman, 17:16:27) * readams says that changing the config dynamically is not the way to do this (tbachman, 17:16:56) * classifier represents dynamic concept, such as lookup in database (i.e. look up of metadata) (tbachman, 17:17:22) * readams recommends move lookup of 5-tuple to different store, which better supports the applications needs (tbachman, 17:21:04) * readams says operational data doesn't belong in the policy, which is a configuration store (tbachman, 17:23:59) * mickey_spiegel notes that we're maybe talking about two APIs here. (tbachman, 17:28:32) * readams asks if there is an orchestration system for the UC&C application to orchestrate this (tbachman, 17:29:10) * uchau says there's an application on the controller (idea is based on ONF use case) (tbachman, 17:29:26) * user app is integrated with UC&C system, network app that is part of the contoller, and is policy based system (tbachman, 17:29:54) * readams says that GBP does not make sense as a generic midlleware layer (tbachman, 17:32:09) * GBP model is different from the way normal network management is done. (tbachman, 17:33:24) * mickey_spiegel notes asks for definition of what uchau means by policy (tbachman, 17:35:00) * losing audio (tbachman, 17:35:31) * regXboi is concerned about narrow definition of what GBP is trying to provide (e.g. SFC) (tbachman, 17:36:49) * if there are orchestration systems NB with a different definition of policy model, he doesn't want us to say "oh we can't talk to you" (tbachman, 17:37:23) * readams notes that if the model is based on fundamentally different principles, this might not make sense. (tbachman, 17:37:50) * regXboi notes that this has to work with other orchestration systems (cough cough *openstack* cough cough) (tbachman, 17:38:49) * readams asserts that in cases where user sees endpoints and communication between these groups of endpoints, then GBP works well (tbachman, 17:40:41) * uchau says that there are users who want to establish link calls (tbachman, 17:43:03) * losing audio (tbachman, 17:43:34) * there are two broad categories of data: operational state data and configuration data (tbachman, 17:53:03) * for example, a new session could be considered operational state data (tbachman, 17:53:17) * the policy needed by a session is considered configuration data (tbachman, 17:53:35) * define a classifier that is "link communication", as "anything that is communication on an active link session" (tbachman, 17:54:05) * semantics around operational and configuration state data are different (tbachman, 17:55:47) * persistence, transactionality, referential integrity (tbachman, 17:55:58) * This affects how we represent this data (tbachman, 17:56:16) * question of can we change actions, classifiers, or tenants in a dynamic fashion? (tbachman, 17:57:14) * it's 11am PST (tbachman, 18:00:17) Meeting ended at 18:06:15 UTC.
