Control Model Nigel Davis (Ciena) From oimt 2020. ND. 006 -View. Context. pptx and TR-512. 8 and TR-512. 7 (at https: //www. opennetworking. org/wp-content/uploads/2018/12/TR 512_v 1. 4_Onf. Core. Im-info. zip)

Introduction • SDN: • Emphasizes networks and software definition • Networks imply functional and physical forms • In 2. 1. 3 TAPI includes both • Software definition implies control • TAPI includes the effect of control but currently not a model of control • The ONF Core Model includes a representation of control • Discussion: • What from the control model is relevant for TAPI • Note that this relates to otcc 2020. ND. 014_TAPI-Build. Context. pptx

TAPI Control • Several considerations • Examining progress of long lived operations via a control task • Monitoring and controlling the control components themselves • As an administrator role • As a client that has been provided with a view of control to monitor/control • Considering the cost/value of each addition • Feature phasing • Release phasing • This meeting is intended to be whiteboard discussion

Exploration

Exploration sketch • CC coordinates view formation • • Has admin focus Has source context, target context and mapping Controlled by a view administrator Has library of view patterns and corresponding mapping patterns • Receives input on desired view • Performs computation using library forms to determine realization and hence mapping • What represents computation capability? PC? CASC? Something else? • Sets up mapping and CD to be used via another control port by another user • • May be same or different CC that provides access EC formed when? And who owns EC? ? • Can modify existing view on change request • Modifies access and mappings • Modification could include Spotlight/Snapshot streaming • All activity coordinated by tasks • Resulting material should be recorded in a supporting document
