def Lowpan.Converter.Converter.ipv6_string_to_headers	(		self,
			ipv6_string
	)

Converts an IPv6 string into IPv6 headers.

The resulting headers are a dictionary which can contain the following fields:

• 'ipv6' the IPv6 header, cut into fields
• 'udp' (if present) the UDP header, cut into fields
• 'payload', (if preset) all remaining bytes
• 'validity', contains string 'valid' or 'invalid'

Precondition:

The string needs to be read beforehand, i.e. from a tun virtual interface.

Call before calling any other function in this module.

Parameters:

ipv6_string

A string of bytes, starting at the first byte of the IPv6 header ending at the last byte of the payload.

Returns:

ipv6_headers A dictionary with the different ipv6_headers and fields in the packet.

def Lowpan.Converter.Converter.ipv6_headers_to_string	(		self,
			ipv6_headers
	)

Converts IPv6 headers into an IPv6 string.

Parameters:

ipv6_headers

IPv6 headers.

Returns:

The corresponding IPv6 string

def Lowpan.Converter.Converter.lowpan_string_to_headers	(		self,
			lowpan_string
	)

Converts a lowpan string into lowpan headers.

The resulting headers are a dictionary which can contain the following fields:

• 'lowpan' the lowpan header, cut into fields
• 'payload', (if preset) all remaining bytes
• 'validity', contains string 'valid' or 'invalid'

Parameters:

lowpan_string

A string of bytes, starting at the first byte of the lowpan header ending at the last byte of the payload.

Returns:

lowpan_headers A dictionary with the different lowpan_headers and fields in the packet.

def Lowpan.Converter.Converter.lowpan_headers_to_string	(		self,
			lowpan_headers
