Thanks for the reply, but excluding the ARP,
Is it possible to receive POSIX TCP or UDP packets using DPDK-application?
Because DPDK application for me right now, only recognizes the packets sent
from DPDK only. But by the sound of it, and based on your reply
DPDK can receive packets from

Currently, I am trying to send ARP requests, but it seems that DPDK

Is there some configuration that needs to be done in order to receive

Hello DPDK experts,
I am having trouble applying ip fragmentation in multiple cores.
*My ultimate questions is whether it is possible to have multiple ip
fragmentation table allocated with each different direct and indirect

Hello DPDK experts,
I am trying to allocate multiple ip frag table for each rx-queue.
For example,
for loop of rx-queues per logical cores

frag_cycles,
Hello DPDK experts
I am trying to assign 8 rx-queue with each different socket ids from
different logical cores.
For example I am using
for (lcore_id = 0; lcore_id < RTE_MAX_LCORE; lcore_id++)
socketid = rte_lcore_to_socket_id(lcore_id);
to get the socket id and trying to assign the pools.
Thank you very much for the reply, this cleared things up.
So in that case, I need a single frag-table correct?
so If I want to receive using multiple rx-queues, the fragmented data can
arrive at different queues, which means I cannot have multiple frag-table.
And does this imply that I have to
Hello DPDK experts,
I have a question of how to ideally use ip fragmentation and assemble using
N number of logical cores each associated with tx queues.
Should the ip fragmentation table be single received by a single rx-queue?
Because I am not sure whether I will receive all the fragmented

But in that case, should I busy wait, to create the delay?
Hello DPDK experts,
I'am testing the performance of DPDK not on high speed polling
but sending each packet with 100 microsecond interval.
As same as the POSIX, DPDK performance degrades into 90 ~ 100 microsecond
round-trip latency per 4KB message.
Is there a way to improve the performance,

Hello DPDK users,
I was struggling with the packet fragmentation,
since the dpdk application(l3fwd, ip-fragmentation, ip-assemble) did not
recognized the received packet as the ipv4 header.
At first, I have crafted my own packets when sending ipv4 headers so I
assumed that I was crafting the
Hello DPDK users,
I have been struggling with how to use the ip fragmentation provided by
DPDK. and was wondering I have the correct concept of IP address and the
MAC address used in rte-mbuf ethernet header.
Is Ip address alone in the header of rte-mbuf used to transfer from local
to remote?

Hello, DPDK users,
I am trying to send 4096 byte of message by splitting the message into 4
packets.
However, Simply sending the messages in bursts does not guarantee that the
messages will be received in order.
For example if I send 3 messages in 3 bursts
I receive messages like this below
Hello, DPDK-users,
I am wondering whether there is a good explanation for high latency caused
by rte_ring when testing the round-trip latency using 1 burst in (tx rx

and calculated the elapsed latency of the round-trip of
Hi Stephen thanks for the reply,
but, what I am asking is using while loop on the rx-queue the proper way
for applications to use DPDK for sending and receiving data? Or is there
any notification mechanism that works even in polling-mode?
Hello
currently, I'am using dpdk by sending and receiving the packets in to the
rte-rings. I'am having difficulty of finding the proper way of to notify
the application that the DPDK received incoming messages.
In order to check the whether the rte_ring has received the data or not, I
run a busy

Hello
I am developing a project with DPDK but have encountered a silly issue,
that is not obvious to me.
I am sending and receiving 4kb rte_mbuf between remote and local node,
that alone works fine,
however when I combine the implemenation with 3rd party library, the DPDK
stops receiving the
Would it be possible to know how I can improve the performance of a
round-trip latency of a single message?
(Or is this not ideal for DPDK?)

Thank you very much Rosen
Your reply gave me good ideas of how to solve the problem.
I've found out the solution by comparing the message size(that I am
sending) with the actual data_length of the rte_mbuf. That way I was able
to allocate the location of my data.

each client and server before increasing the size of the packets.
Does this problem have to do with the NIC architecture?
If so, is there a document to find out the correct limit size for the
packets?

since my implementation is just pingpong and have very simple
implementation, I don't believe that there should be any packet losses in
my case.
