arrayToUINT64()

template<size_t N>

static uint64_t E::NetworkUtil::arrayToUINT64 ( const std::array< uint8_t, N > &  array )

inlinestatic

Converts a std::array to uint64_t.

Parameters

N	Size of array
array	Array to convert. ipv4_t and mac_t are also okay.

Returns

Converted uint64_t

one_sum()

uint16_t E::NetworkUtil::one_sum ( const uint8_t *  buffer, size_t  size  )

static

Calculate checksum once

Parameters

buffer	Buffer to calculate.
size	Size of buffer.

Returns

Checksum

tcp_sum()

static uint16_t E::NetworkUtil::tcp_sum ( uint32_t  source, uint32_t  dest, const uint8_t *  tcp_seg, size_t  length  )

static

Calculate TCP checksum.

Parameters

source	Source address (pseudo header)
dest	Destination address (pseudo header)
tcp_seg	TCP segment
length	TCP length (pseudo header)

Returns

Checksum

Note

See RFC 793 Checksum

UINT64ToArray()

template<size_t N>

static std::array<uint8_t, N> E::NetworkUtil::UINT64ToArray ( uint64_t  val )

inlinestatic

Converts a uint64_t variable to std::array

Parameters

N	Size of array
val	uint64_t variable

Returns

Converted array
