Detailed Description

Packets contain Messages. They are coalesced up up to the available MTU size, to save power on devices where transmission may have a high energy cost.

[static]

[const]

Returns: the size of the packet payload.

[const]

Returns: the amount of free space in this packet for an OLSR packet payload, after MTU is taken into account.

[const]

Returns: the size of the packet payload which will fit inside the MTU without splitting any messages. If no MTU is set, returns length().

Decode an OLSR packet header.

An OLSR packet is considered valid if its length is greater than the size of a standard packet header. The host IP stack takes care of UDP checksums, IP fragmentation and reassembly, and MTU size checks for us.

Encode a packet, including any nested messages.

[const]

[const]

[const]

[const]

Returns: a string representation of the entire packet.

Get a non-const reference to a packet's messages. For debugging use only, ie in simulation of multiple hops.

Returns: reference to the messages contained within the packet.
