Member Function Documentation

Ptr<Packet> ns3::ArpCache::ArpCache::Entry::DequeuePending

(

void

)

Returns:

0 is no packet is pending, the next packet to send if packets are pending.

Ipv4Address ns3::ArpCache::ArpCache::Entry::GetIpv4Address

(

void

)

const

Returns:

The Ipv4Address for this entry

Address ns3::ArpCache::ArpCache::Entry::GetMacAddress

(

void

)

const

Returns:

The MacAddress of this entry

uint32_t ns3::ArpCache::ArpCache::Entry::GetRetries

(

void

)

const

Returns:

number of retries that have been sent for an ArpRequest in WaitReply state.

bool ns3::ArpCache::ArpCache::Entry::IsAlive

(

void

)

Returns:

True if the state of this entry is alive; false otherwise.

bool ns3::ArpCache::ArpCache::Entry::IsDead

(

void

)

Returns:

True if the state of this entry is dead; false otherwise.

bool ns3::ArpCache::ArpCache::Entry::IsExpired

(

void

)

const

Returns:

True if this entry has timed out; false otherwise.

This function returns true if the time elapsed strictly exceeds the timeout value (i.e., is not less than or equal to the timeout).

bool ns3::ArpCache::ArpCache::Entry::IsWaitReply

(

void

)

Returns:

True if the state of this entry is wait_reply; false otherwise.

(

Ptr< Packet >

waiting

)

Parameters:

waiting

void ns3::ArpCache::ArpCache::Entry::SetIpv4Address

(
