f49ebfe1c4 Temporarily disabled rime route udp because it breaks with newest MAC interfaces 2010-02-18 21:53:08 +00:00
adamdunkels
e34eb54960 A work-in-progress rework of the Contiki MAC and radio layers. The
main ideas are:

* Separates the Contiki low-layer network stack into four layers:
  network (e.g. sicslowpan / rime), Medium Access Control MAC
  (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
  radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
  that specify what mechanism/protocol/driver to use at the four
  layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
  NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
  the fate of a transmitted packet: if the packet was not possible to
  transmit, the cause of the failure is reported, and if the packets
  was successfully transmitted, the number of tries before it was
  finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
  which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
  efficient radio duty cycling protocols: channel check, pending
  packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
  #defines.

583dd11c55 rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value.
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values

5aab2eb77d A simple addition with significant performance implications:
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

fe30886b37 Added functionality for decaying routes: when a packet is sent over a route, it is decayed. If the route is not refreshed within four packets (with the route_refresh() function, which is called when a new packet arrives), the route is dropped. A route can be decayed at most once per second 2009-05-10 21:08:01 +00:00

c83c5c4c55 Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception) 2009-05-04 11:23:30 +00:00

e70cf0c7c6 Rewrite of the collect module. The new version uses a packet queue for outgoing and forwarded packets so that more than one packet can be forwarded at the same time. The new version uses the packetqueue module to maintain the packet queue. 2009-04-29 20:48:57 +00:00
