Minimal Viable Detailed Requirements Taken from the “Project Box” on previous slides The OPNFV SFQM Brahmaputra Release cannot release without these: DPDK Stats Extensions Deliverables: IXGBE error/extended stats Exposure i40e error/extended stats Exposure Sample App that retrieves stats on the Host Sample App that retrieves stats on the Guest Sample App that retrieves Host stats on the Host Description: Development activity to support the exposure of NIC MAC/PHY Level Counters, particularly for packet drops and errors. Functional Requirements: Expose error/drop registers to DPDK Sample Apps Expose VF including error/drop registers to DPDK Sample Apps Extend Exposed registers to include those not in struct hw_stats Extend Exposed registers to include Sums that are not in struct hw_stats Performance Requirements: Does NOT impact performance. Targeted DPDK release: DPDK 2.1 and DPDK 2.2 (November 30th 2015) Notice: This is still a draft

Minimal Viable Detailed Requirements Taken from the “Project Box” on previous slides The OPNFV SFQM Brahmaputra Release cannot release without these: CollectD DPDK stats Plugin Deliverable: CollectD Plugin for DPDK stats Description: CollectD Plugin that runs on the host and polls stats from DPDK Functional Requirements: Runs on the Guest/Host. Collects PF/VF Stats. Performance Requirements: Does NOT impact performance. Targeted DPDK release: upstream to github by the end of October as there is no release cadence for CollectD. Status: To be started. Notice: This is still a draft

Minimal Viable Detailed Requirements Taken from the “Project Box” on previous slides The OPNFV SFQM Brahmaputra Release cannot release without these: FEATURE: DPDK KEEP ALIVE (KA) Deliverable: DPDK Keep Alive Sample App on Guest (A simple forwarding app with DPDK KA functionality) Description: Development activity to support detection of ‘failed’ DPDK cores and notification to a HA/SA middleware. The purpose is to detect Packet Processing Core fails (e.g. infinite loop) and ensure the failure of the core does not result in a fault that is not detectable by a management entity. Functional Requirements: Runs on the Guest. Runs on the Host. Configurable timeouts. Measures detection time. Has a hook function where HA/SA middleware can hook in for fault management notifications. Performance Requirements: Does NOT impact performance. Targeted DPDK release: DPDK 2.2 (November 30th 2015) Status: In Progress Notice: This is still a draft
