Hi,
I have FD.IO setup to receive a multicast stream. I would like to create a c++
app to process the udp messages but I am having trouble figuring out what api
to use and how to set this up.
The messages I am trying to processes are as follows:
00:14:50:997590: dpdk-input
GigabitEthernet6/0/3 rx queue 0
buffer 0xddcbf8: current data 14, length 1428, free-list 0, clone-count 0,
totlen-nifb 0, trace 0x9
PKT MBUF: port 2, nb_segs 1, pkt_len 1442
buf_len 2176, data_len 1442, ol_flags 0x180, data_off 128, phys_addr
0x932bd00
packet_type 0x211
Packet Offload Flags
PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid
PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid
Packet Types
RTE_PTYPE_L2_ETHER (0x0001) Ethernet packet
RTE_PTYPE_L3_IPV4 (0x0010) IPv4 packet without extension headers
RTE_PTYPE_L4_UDP (0x0200) UDP packet
IP4: 00:02:c5:1b:51:07 -> 01:00:5e:00:00:01
UDP: 10.10.10.33 -> 232.0.0.1
tos 0x00, ttl 64, length 1428, checksum 0x392d
fragment id 0x0000, flags DONT_FRAGMENT
UDP: 1000 -> 5001
length 1408, checksum 0x0000
00:14:50:997591: ip4-input-no-checksum
UDP: 10.10.10.33 -> 232.0.0.1
tos 0x00, ttl 64, length 1428, checksum 0x392d
fragment id 0x0000, flags DONT_FRAGMENT
UDP: 1000 -> 5001
length 1408, checksum 0x0000
00:14:50:997592: ip4-mfib-forward-lookup
fib 0 entry 6
00:14:50:997592: ip4-mfib-forward-rpf
entry 6 3 Accept,
Which API should I use to accomplish this?
Thanks,
Guy
