History
adamdunkels 7165a3866f Significant rework of the Contiki data collection protocol: 
* the new version makes use of MAC-layer feedback so that bad paths
  can be identified quicker and then avoided.

* the new code uses transport layer ACKs that contain feedback from
  the collect protocol: when a packet cannot be forwarded due to lack
  of resources, the ACK contains a flag that indicates that the packet
  could not be forwarded. ACKs also contain the routing metric of the
  sender, which improves agility in face of rapid path changes.

* loop detection and management has been improved: with higher path
  metric agility, the system is more prone to short-lived routing
  loops. Instead of dropping looping packets, the new version adjusts
  the routing metric for the routes that exhibit loops so that the
  risk for future loops is reduced.

* make use of packet attributes to inform the MAC layer of how many
  times packets should be retransmitted.

netstack.h Changed the network stack to use different structures for the different layers (network_driver, mac_driver, rdc_driver, radio_driver). This helps to avoid incorrect configuration. 2010-02-23 20:09:11 +00:00
psock.c *** empty log message *** 2009-07-23 16:13:48 +00:00

rawpacket.h Added *experimental* module for sending raw (non-routed) packets from Contiki. The name of the module is likely to change. 2006-10-22 12:31:46 +00:00
resolv.c Remove compiler warning 2010-02-15 20:49:38 +00:00

slipdev.c Import of the contiki-2.x development code from the SICS internal CVS server 2006-06-17 22:41:10 +00:00

tcpdump.h corrected function signature 2007-08-06 13:14:09 +00:00
tcpip.c Major bugfix, found by Raimondas Sasnauskas: the TCP periodic timer was not started when a new connection request arrived. If there were no other active TCP connections, this means that the SYNACK would never be retransmitted, potentially leading to a forever stale TCP connection. 2010-02-09 12:58:53 +00:00
tcpip.h Changed to use separate Contiki event type for ICMP6 notifications 2010-02-05 12:43:36 +00:00

uaodv-rt.h * Make it explicit that some seqno:s are in host byte order by naming 2007-05-09 13:45:16 +00:00
uaodv.c removed compiler specific attribute 2010-01-20 09:58:16 +00:00
uaodv.h including uaodv-rt 2007-12-13 10:04:59 +00:00

uip-neighbor.c Remove unguarded printf() 2008-11-09 12:16:05 +00:00
uip-neighbor.h Change typedef of uip_ipaddr_t from a vector type to a union. 2006-08-09 16:13:39 +00:00
uip-netif.c Bugfix: the compile-time check for UIP_LLADDR_LEN previously generated a run-time error, when it should have generated a compile-time error 2010-02-28 08:30:39 +00:00
uip-netif.h changed timer to stimer for neighbor, prefix, default router, address list 2009-02-19 16:42:41 +00:00
uip-over-mesh.c Disable the stream mode for TCP packets since it does not seem to work reliably with cxmac 2010-02-04 18:57:33 +00:00
uip-over-mesh.h Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node. 2008-11-09 12:20:56 +00:00
uip-split.c Bugfix: split full size TCP segments if they match the MSS definition, not only the buffer size definition 2010-01-25 13:53:15 +00:00
uip-split.h Import of the contiki-2.x development code from the SICS internal CVS server 2006-06-17 22:41:10 +00:00

uipopt.h Made TCP MSS configurable 2009-04-10 00:37:48 +00:00
