From 7286b2518ec8e4398b512ce95def9166a7af2e4a Mon Sep 17 00:00:00 2001 From: Deepak S Date: Thu, 13 Jul 2017 21:26:50 -0700 Subject: Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNF JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S --- VNFs/DPPD-PROX/expire_cpe.c | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 VNFs/DPPD-PROX/expire_cpe.c (limited to 'VNFs/DPPD-PROX/expire_cpe.c') diff --git a/VNFs/DPPD-PROX/expire_cpe.c b/VNFs/DPPD-PROX/expire_cpe.c new file mode 100644 index 00000000..4f2f5cd8 --- /dev/null +++ b/VNFs/DPPD-PROX/expire_cpe.c @@ -0,0 +1,43 @@ +/* +// Copyright (c) 2010-2017 Intel Corporation +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. +*/ + +#include + +#include "hash_entry_types.h" +#include "hash_utils.h" +#include "expire_cpe.h" + +#define MAX_TSC __UINT64_C(0xFFFFFFFFFFFFFFFF) + +void check_expire_cpe(void* data) +{ + struct expire_cpe *um = (struct expire_cpe *)data; + uint64_t cur_tsc = rte_rdtsc(); + struct cpe_data *entries[4] = {0}; + void *key[4] = {0}; + uint64_t n_buckets = get_bucket_key8(um->cpe_table, um->bucket_index, key, (void**)entries); + + for (uint8_t i = 0; i < 4 && entries[i]; ++i) { + if (entries[i]->tsc < cur_tsc) { + int key_found = 0; + void* entry = 0; + rte_table_hash_key8_ext_dosig_ops.f_delete(um->cpe_table, key[i], &key_found, entry); + } + } + + um->bucket_index++; + um->bucket_index &= (n_buckets - 1); +} -- cgit 1.2.3-korg
