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...
