hi,
I am trying to send a MAC broadcast message in response to having overheard
something. So I create and send a packet as follows (inside recvDATA before
address filtering):
Packet* report_pkt =
Packet::alloc();
hdr_ip* iph_report =
hdr_ip::access(report_pkt);
hdr_cmn* ch_report =
hdr_cmn::access(report_pkt);
hdr_wd* wd_report =
hdr_wd::access(report_pkt);
ch_report->direction() =
hdr_cmn::DOWN;
ch_report->next_hop() =
IP_BROADCAST;
ch_report->addr_type() =
NS_AF_INET;
ch_report->ptype() = PT_MAC;
//method to set address
iph_report->saddr() =
Address::instance().create_ipaddr(NodeId,RT_PORT);
iph_report->daddr() =
IP_BROADCAST;
iph_report->sport() =
RT_PORT;
iph_report->dport() =
RT_PORT;
iph_report->ttl() =
IP_DEF_TTL;
hdr_mac *mh_report =
HDR_MAC(report_pkt);
wd_report->is_bad_ = 1;
wd_report->watchdog_id_ =
NodeId;
wd_report->watched_id_ =
sorc;
send(report_pkt,0);
Then I put the following check in recvDATA:
if(dst == MAC_BROADCAST) {
if(ch->direction()==hdr_cmn::UP)
if ( wd->BadCheck()==1 )
printf("In broadcast I am
node %d and I heard a badness report for %d from ip src%d %d bad report %d
dst is %d \n", netif_->node()->nodeid(), wd->WatchedID(), ssriph->saddr(),
wd->WDID(), wd->BadCheck(), ssriph->daddr());
}
The problem is, only node 0 is receiving these messages. No other node
receives this message. Can anyone please give any suggestions, I have been
stuck here for a week now. Should I put this functionality somewhere else
maybe?
thanks
