	* to be ~~added~~		* In the meet on 11th August it was decided that only L4S mode will be implemented for FqPIE, not the threshold which is used for DCTCP. For L4S mode it was decided that if the packet is ECT1 and L4S is enabled then the packet would bypass PIE and get marked based on CE threshold and other packets would go through PIE.

			Work done in this week includes:
			* Implementing L4S mode for FqPIE Queue disc.
			* Adding unit test cases for FqPIE
			* Documentation of FqPIE, work for FqPIE available on my [https://gitlab.com/bhaskar792/ns-3-dev/-/tree/FqPIE_over_RFC_MR GitLab repository].
			* Implementing Active/Inactive feature for PIE available on my [https://gitlab.com/bhaskar792/ns-3-dev/-/tree/Active-Inactive GitLab repository]

	Phase 3 project definition will be informed by any IETF tsvwg outcomes from the next week's IETF 108 meeting.		Phase 3 project definition will be informed by any IETF tsvwg outcomes from the next week's IETF 108 meeting.

			Work done in this week (available at my Gitlab [https://gitlab.com/bhaskar792/ns-3-dev/-/tree/FqCobalt repository])
			* Implementation of FqCobalt Queue Disc with L4S mode, ECN, and set-associative hash using the existing implementation of FqCoDel.
			* Implementation of CE threshold marking and L4S mode Cobalt Queue disc.
			* Addition of unit test cases for FqCobalt Queue disc.
			* Addition of the CE threshold marking test for Cobalt Queue Disc.
			* Review of ACK filtering [https://gitlab.com/nsnam/ns-3-dev/-/merge_requests/346 Merge Request]

			After the meet on 28th July it was decided that Phase 3 will consists of the inclusion of FqPIE to the mainline ns-3 and inclusion of AQM Evaluation Suite to the ns-3 Appstore.

	* '''Project Goals:''' The project ~~aims~~ to implement the Some Congestion Experienced (SCE) marking feature which uses ECT(1) codepoint of Explicit Congestion Notification (ECN) to deliver the earlier notification of congestion than the Congestion Experienced (CE) mark along with the TCP which responds appropriately to the SCE feedback. The project also intends to implement Controlled Delay Approximate Fairness (CoDelAF) AQM with Cheap Nasty Queueing (CNQ) and Lightweight Fair Queueing (LFQ) with SCE support. As simulation models already exist for many of the Low Latency, Low Loss, Scalable throughput (L4S) components, the project ultimately aims to provide the feature to experiment with SCE and L4S to the ns-3 community.		* '''Project Goals:''' The project originally aimed to implement the Some Congestion Experienced (SCE) marking feature which uses ECT(1) codepoint of Explicit Congestion Notification (ECN) to deliver the earlier notification of congestion than the Congestion Experienced (CE) mark along with the TCP which responds appropriately to the SCE feedback.
