2019-11-22[HICN-405] Added application face deleteAlberto Compagno2-2/+4
Added two new messages in the binary api: - hicn_api_face_cons_del to delete a consumer face - hicn_api_face_prod_del to delete a producer face Added the corresponding commands in the vpp_api_test for debugging and testing Reworked the cache policy structure to add a new function that flash the content store from the content coming from the destroyed producer face. This is required since the CS while each producer face has its own lru list. Removing only the producer face without flushing the CS from the content coming from the producer face will lead to a segfault in case there is a hit in the CS as the lru no longer exists and it won't be possible to update the head of the lru.

2019-11-22[HICN-411] Change how manifests are requestedOlivier Roques3-90/+73
This patch introduces a new way of requesting manifests such that all the segments they contain fill the current transport window. When a manifest (M) is received, we compute L = last_segment_requested + current_window_size. L is therefore equal or greater than the last segment of the current window. Then we compare L to the suffix of the next manifest that will be (potentially) requested. If L > next_manifest, it means that the last segment of the window is greater than the first segment contained in the next manifest. Therefore we request manifests until L <= next_manifest, ie until the manifests would cover the entire window. If L <= next_manifest, then all the manifests that were requested already cover the window, so there's no need to request more. However if the next manifest immediately follows the current one (M), we still need to request it so that the content suffix queue is correctly updated.

2019-11-20[HICN-402] Limit in-flight interests for manifestsOlivier Roques3-2/+25
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-393] Fix various issues related to manifestsOlivier Roques7-20/+50
The current manifest implementation is broken: 1. ManifestIndexingManager, responsible for validating manifests and segments and retrieving the next ones, assumes that all manifests have the same size. This assumption affects the retrieval of next manifests which is based on the number of segments the current manifest contains. Therefore when a non-full manifests arrives, the computed suffix of the next manifest is wrong and refer to a content instead, which results in an error. 2. Manifests are used to update a suffix queue which stores all the segments listed in manifests. This queue is used to retrieve content sequentially via a pointer indicating the next content to fetch. When the pointer reaches the end of the suffix queue, the consumer stops sending interests. The correct behavior would be to wait for a new manifest which would update the queue. This patch fixes these two issues: 1. Issue 1 was fixed by using SuffixManifest (HICN-392). This allows to set the capacity of a manifest at the start of the consumption instead of checking each time the size of the current manifest and then using that (non-constant) value to retrieve the next manifests. 2. Issue 2 was fixed by passing to ManifestIndexingManager a reference to an object capable of calling the scheduleNextInterest function, which is then called after a new manifest is retrieved to make sure interests for content kept being sent. This is not an optimal solution but rather a temporary one, until the retrieval of manifests is done at the transport level rather than in ManifestIndexingManager. This patch also changes the order of production: manifests are now sent before content. To do so, contents are added into a queue until the manifest is complete.

2019-11-14[HICN-392] Assign independent suffixes for manifests/contentsOlivier Roques9-42/+270
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...
