In resource reservation, VIM reserves resources for a certain -period as requested by the NFVO. A resource reservation will have a start time -which could be into the future. Therefore, the reserved resources shall be -available for the NFVO requested purpose (e.g. for a VNF) at the start time for -the duration asked by NFVO. Resources include all three resource types in an -NFVI i.e. compute, storage and network. - -Besides, NFVO requires abstracted NFVI resource capacity information in order -to take decisions on VNF placement and other operations related to the virtual -resources. VIM is required to inform the NFVO of NFVI resource state -information for this purpose. Promise project aims at delivering the detailed -requirements on these two features defined in ETSI NFV MAN GS [5], the list of -gaps in upstream projects, potential implementation architecture and plan, and -the VIM northbound interface specification for resource reservation and -capacity management. - -Problem description -=================== - -OpenStack, a prominent candidate for the VIM, cannot reserve resources for -future use. OpenStack requires immediate instantiation of Virtual Machines -(VMs) in order to occupy resources intended to be reserved. Blazar can reserve -compute resources for future by keeping the VMs in shelved mode. However, such -reserved resources can also be used for scaling out rather than new VM -instantiation. Blazar does not support network and storage resource reservation -yet. - -Besides, OpenStack does not provide a northbound interface through which it can -notify an upper layer management entity e.g. NFVO about capacity changes in its -NFVI, periodically or in an event driven way. Capacity management is a feature -defined in ETSI NFV MAN GS [5] and is required in network operation. |
