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/dpi/dpi.h | 76 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 76 insertions(+) create mode 100644 VNFs/DPPD-PROX/dpi/dpi.h (limited to 'VNFs/DPPD-PROX/dpi/dpi.h') diff --git a/VNFs/DPPD-PROX/dpi/dpi.h b/VNFs/DPPD-PROX/dpi/dpi.h new file mode 100644 index 00000000..5ce1015d --- /dev/null +++ b/VNFs/DPPD-PROX/dpi/dpi.h @@ -0,0 +1,76 @@ +/* +// 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. +*/ + +#ifndef _DPI_H_ +#define _DPI_H_ + +#include +#include +#include + +struct flow_info { + uint32_t ip_src; + uint32_t ip_dst; + uint8_t ip_proto; + uint16_t port_src; + uint16_t port_dst; + uint8_t reservered[3]; +} __attribute__((packed)); + +struct dpi_payload { + uint8_t *payload; + uint16_t len; + uint16_t client_to_server; + struct timeval tv; +}; + +struct dpi_engine { + /* Returns 0 on success, This function is called from an + arbitrary thread before any other function in this struct + is called. */ + int (*dpi_init)(uint32_t thread_count, int argc, const char *argv[]); + /* Return the size that should be allocated in the flow + table.
