2019-11-20	[HICN-402] Limit in-flight interests for manifests	Olivier Roques	1	-0/+5
	Currently, interests for manifests are sent independently of the transport protocol. When receiving a manifest, interests for next manifests are sent until the next window would be full of data segments. But there is no limit on the number of interests for manifests that can be sent. After a while, the interest input buffer in the producer's side is full of them and cannot satisfy the requests quickly enough. This results in a large drop of bandwidth on the consumer side. This patch allows to limit the number of in-flight interests for manifests. Signed-off-by: Olivier Roques <olvrqs@gmail.com> Change-Id: Ic497bd55fd92233e4b47b04635fb9bf75506375e
2019-11-14	[HICN-392] Assign independent suffixes for manifests/contents	Olivier Roques	1	-0/+134
	This patch introduces a new class, SuffixStrategy and two sub-classes, SuffixContent and SuffixManifest which allow to independently assign suffixes to contents and manifests respectively. The produce() function in socket_producer.cc has also been changed to use them. Given a strategy and an offset (and optionally the capacity of a manifest), these classes automatically compute the correct next suffixes for both type of data (manifest or content). This removes the burden of having to manage suffixes for instance when producing or when retrieving content, and could be expanded to add more strategy in the future. Currently the only existing strategy is "INCREMENTAL": manifests with capacity N have a suffix multiple of N+1: 0, N+1, 2(N+1) etc. Contents have a suffix incremented by 1 except when it conflicts with a manifest: 1, 2, ..., N, N+2, N+3, ..., 2N+1, 2N+3...
