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 --- .../helper-scripts/dpi/sutstatsconsfile.py | 61 ++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 VNFs/DPPD-PROX/helper-scripts/dpi/sutstatsconsfile.py (limited to 'VNFs/DPPD-PROX/helper-scripts/dpi/sutstatsconsfile.py') diff --git a/VNFs/DPPD-PROX/helper-scripts/dpi/sutstatsconsfile.py b/VNFs/DPPD-PROX/helper-scripts/dpi/sutstatsconsfile.py new file mode 100644 index 00000000..82bca9a8 --- /dev/null +++ b/VNFs/DPPD-PROX/helper-scripts/dpi/sutstatsconsfile.py @@ -0,0 +1,61 @@ +#!/bin/env python + +## +## 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. +## + +from statsconsfile import * +from decimal import * + +class SutStatsConsFile: + def __init__(self, fileName, offset): + self.offset = offset; + self.statsConsFile = StatsConsFile(fileName) + + def readNext(self): + entry = self._readNextEntry(); + + if (entry is None): + return None; + + while (entry is not None and entry[-1] <= 0): + entry = self._readNextEntry(); + return entry; + + def getHz(self): + return self.statsConsFile.getHz(); + + def _readNextEntry(self): + entry = self.statsConsFile.readNext(); + if (entry is None): + return None; + + rx = 0; + tx = 0; + drop = 0; + last_tsc = 0; + + for i in range(0, len(entry), 2): + rx += entry[i][2] + tx += entry[i][3] + drop += entry[i][4] + last_tsc = entry[i][5] + + last_tsc -= self.offset; + last_tsc = Decimal(last_tsc) / self.statsConsFile.getHz(); + return [rx, tx, drop, last_tsc]; + + def close(self): + self.statsConsFile.close(); -- cgit 1.2.3-korg
