2020-05-29Added initial support for BGPXavier Simonart1-0/+13
Through this commit BGP messages are forwarded to tap device Netlink messages are enabled to receive route Updates. In addition, generating tasks can also specify a routing table which will be used when sending packets The routes initialized by the routing table can be changed through the reception of BGP messages Change-Id: I187ba9a921885cbc9b209aae5fb654309e3388b8 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2020-05-29Added support for netlinkXavier Simonart1-9/+31
Through this commit ARP and ICMP messages are forwarded to the kernel when vdev tap devices are enabled, as well as PROX l3 mode. ICMP support has also been added to master (i.e. PROX L3 mode) and to swap (so when L3 submode is not enabled).

2019-03-06PROX generator: performance optimization (2/4)Xavier Simonart1-33/+0
Improve PROX generator performance by pre-calculating bytes_to_tsc. This improvement is only implemented for non-pcap generator, where only few different packet sizes are usually generated. This change might have a negative performance impact in some cases, if many different packet sizes are generated, resulting in higher memory usage. This is the case for instance if random is applied to packet size. In addition, simplified the rx path, receiving now only MAX_PKT_BURST packets per handle loop. Before we were trying to empty the NIC looping on RX packets, ending up with many rx packets per handle loop. This was used to determine an lower bound for the time the packet was received. We now set the lower bound when less than MAX_PKT_BURST has been received. Change-Id: I1ce813d7e4ac1577ea412c590add5d6f94b36ec7 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-10-28Add support for counting non dataplane related packetsXavier Simonart1-2/+2
When performing some zero packet loss performance testing on dataplane, it is important (not) to count non dataplane packets. For instance, one might receive uexpected packets from a switch, or ARP packets. Or one might need to transmit ARP packets. Such packets should not be counted as dataplane packets as for thse packets there is no 1:1 mapping between transmitted packets and received packets. To support this, the counters reporting numbers of transmitted and received packets remain unchanged but two new counters have been added to PROX, counting respectively number of received and number of transmitted non-dataplane packets. On RX side, packets are counsidered as non-dataplane if being ARP or if they do not countain the proper signature On TX side, ARP packets are not considered as dataplane packets. This feature requires configuration of signature. "dp core stats" command has been added Change-Id: I98e113cd02f36d540383d343a433592867ad86a9 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-02-13Fix potential crash in rx and tx distributionXavier Simonart1-1/+4
In some (rare) modes, more than 64 packets can be received through one rx function. This is for instance the case of the lat mode. Change-Id: Ie733c927a8e116c679c464f2551768185ef85366 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-01-16Fix dumping receive packetsXavier Simonart1-5/+6
There were two issues identified in dump receive packets - when the receive packets was going to be dropped (and not transmitted), it was also printed as TX[255]. - a potential crash when using the dump function with modes like lat which can receive more than MAX_RING_BURST. Those issues have been fixed. Change-Id: Ia2297539d64961a211389d68e3c9c6280472243c Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-01-08Fix stacking of rx receive functionsXavier Simonart1-7/+3
PROX can stack different RX functions, so that they are executed after each other. This feature is for instance used to dump packets or to print distribution of receive packets, without influencing the performance of the rx functions when no dump or print is needed. The previous implementation was wrong and causing some of the stacked functions not to be executed. This was causing for instance issues in latency measurement after enabling dumping packets.

2017-07-14Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNFDeepak S1-0/+427
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...
