2020-05-04[HICN-590] Removed andjacency type specific face implementationAlberto Compagno1-919/+0
Changes in the new implementation are: - the adjacency index is replaced with a dpo that allows the single face node to dispatch the packet to the right vlib node. - local and remote address in the face are replaced with a single nat address which is used to perform the nat operation when rewriting an interest or a data (in case of tunnels the nat address will be equal to 0) - the list of next hop in the load balance is no longer a list of dpos but a list of face id (this makes the code easier and increases the number of next hop we supports) Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com> Change-Id: I4ac2b4eb09425bfe1b3ca9f82d7d0ff564297b0d

- Handling the case in which a pushed data hit an existing pit entry (created after the data has gone through the data_pcslookup_node). In this case the data packet is forwarded to the data_fwd_node - Handling the case in which the hash table (in pcs) is full and it is not possible to allocate another bucket. In this case the packet is dropped. - Copying packets whose length is less than 128B. VPP prevents to create a chain of vlib_buffer where the first, or middle, vlib_buffer are holding less then 128B. [HICN-72] - Assign a /128 subnet to the producer app face. Change-Id: I6c19d6d127774a7f59ac69ac965d4bcd6a72becc Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>

2019-01-19Improved performance on data-fwd node:Alberto Compagno1-4/+4
- Removed full pit entry initialization in favor of a lighter initialization on few fields - Squeezed pit entry size in order to store only the number of incomplete faces (as set in HICN_PARAM_PIT_ENTRY_PHOPS_MAX). The bitmap size is now determined by HICN_PARAM_FACES_MAX and optimized to do a fast lookup Replaced the field is_appface with the field flags in the hicn_buffer_t: - is_appface is now a flag with value 0x01 (HICN_BUFFER_FLAGS_FACE_IS_APP) - Added flag HICN_BUFFER_FLAGS_PKT_LESS_TWO_CL (0x02) to handle the copy of pkt with length < than 2*CACHE_LINES (in this case cloning is prevented by the cloning function in vpp). Such flag is initialized by the incoming face of the pkt. Change-Id: Ia956fd5719a28ee29f7fa2fd23d283964743efd8 Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>
