Detailed Description

LogicalLink is so named because it is mostly independent of the underlying link layer. OLSR uses link-layer broadcasts or multicasts for the purposes of neighbor discovery, and links are created through the exchange of HELLO messages. LogicalLink may be associated with link-layer specific state, e.g. that of an 802.11s mesh portal.

 LogicalLink (Neighborhood* tm, EventLoop& eventloop, const OlsrTypes::LogicalLinkID id, const TimeVal& vtime, const IPv4& remote_addr, const IPv4& local_addr)

LogicalLink

inline OlsrTypes::LogicalLinkID  id ()

id

[const]

Returns: the ID of this link.

inline OlsrTypes::NeighborID  neighbor_id ()

neighbor_id

[const]

Returns: the ID of the neighbor at the far end of this link.

inline void  set_neighbor_id (OlsrTypes::NeighborID neighborid)

set_neighbor_id

Set the ID of the neighbor at the far end of this link.

Parameters:

neighboridthe ID of the neighbor.
inline Neighbor*  destination ()

destination

[const]

Returns: the cached Neighbor pointer.

inline void  set_destination (Neighbor* n)

set_destination

Set the cached neighbor pointer.

Parameters:

nthe Neighbor pointer.
inline OlsrTypes::FaceID  faceid ()

faceid

[const]

Returns: the ID of the local interface where this link resides.

inline void  set_faceid (OlsrTypes::FaceID faceid)

set_faceid

Set the ID of the local interface where this link resides.

Parameters:

faceidthe ID of the local interface.
inline IPv4  local_addr ()

local_addr

[const]

Returns: the protocol address of the local interface.

inline IPv4  remote_addr ()

remote_addr

[const]

Returns: the protocol address of the neighbor's interface.

inline double  near_etx ()

near_etx

[const]

Returns: the near end ETX measurement.

inline double  far_etx ()

far_etx

[const]

Returns: the far end ETX measurement.

void  update_timers (const TimeVal& vtime, bool saw_self = false, const LinkCode lc = LinkCode())

update_timers

Update the link timers, based on the information present in a HELLO message. Section 7.1.1, 2: HELLO Message Processing.

Parameters:

vtimeThe validity time present in the HELLO message.
saw_selftrue if the neighbor advertised our own address.
lcthe link code with which our address was advertised.
OlsrTypes::LinkType  link_type ()

link_type

[const]

Determine the current state of the link. Section 6.2, 1: HELLO Message Generation, Link Type.

Returns: The link type code representing this link's state.

inline bool  is_sym ()

is_sym

[const]

Returns: true if this link is symmetric.

inline TimeVal  sym_time_remaining ()

sym_time_remaining

[const]

Returns: the amount of time remaining until the SYM timer fires.

inline TimeVal  asym_time_remaining ()

asym_time_remaining

[const]

Returns: the amount of time remaining until the ASYM timer fires.

inline TimeVal  time_remaining ()

time_remaining

[const]

Returns: the amount of time remaining until the DEAD timer fires.

inline bool  pending ()

pending

[const]

Determine if a link is pending (i.e. not yet established).

Returns: true if the link is pending.

void  event_sym_timer ()

event_sym_timer

Callback method to: service a LogicalLink's SYM timer.

void  event_asym_timer ()

event_asym_timer

Callback method to: service a LogicalLink's ASYM timer.

void  event_lost_timer ()

event_lost_timer

Callback method to: service a LogicalLink's LOST timer.

void  event_dead_timer ()

event_dead_timer

Callback method to: service a LogicalLink's DEAD timer. This is immediately passed to the parent Neighborhood as the link may be deleted.
