Detailed Description

 MfeaDft (MfeaNode& mfea_node)

MfeaDft

Constructor for a given MFEA node.

Parameters:
mfea_nodethe MfeaNode this table belongs to.

 ~MfeaDft ()

~MfeaDft

[virtual]

Destructor

MfeaNode&  mfea_node ()

mfea_node

[const]

Get a reference to to the MFEA node this table belongs to.

Returns: a reference to the MFEA node (MfeaNode) this table belongs to.

int  family ()

family

[const]

Get the address family.

Returns: the address family (e.g., AF_INET or AF_INET6 for IPv4 and IPv6 respectively).

int  add_entry (const IPvX& source, const IPvX& group, const struct timeval& threshold_interval, uint32_t threshold_packets, uint32_t threshold_bytes, bool is_threshold_in_packets, bool is_threshold_in_bytes, bool is_geq_upcall, bool is_leq_upcall)

add_entry

Add a dataflow entry.

Note: either is_threshold_in_packets or is_threshold_in_bytes (or both) must be true. Note: either is_geq_upcall or is_leq_upcall (but not both) must be true.

Parameters:
sourcethe source address.
groupthe group address.
threshold_intervalthe dataflow threshold interval.
threshold_packetsthe threshold (in number of packets) to compare against.
threshold_bytesthe threshold (in number of bytes) to compare against.
is_threshold_in_packetsif true, threshold_packets is valid.
is_threshold_in_bytesif true, threshold_bytes is valid.
is_geq_upcallif true, the operation for comparison is ">=".
is_leq_upcallif true, the operation for comparison is "<=".

Returns: XORP_OK on success, otherwise XORP_ERROR.

int  delete_entry (const IPvX& source, const IPvX& group, const struct timeval& threshold_interval, uint32_t threshold_packets, uint32_t threshold_bytes, bool is_threshold_in_packets, bool is_threshold_in_bytes, bool is_geq_upcall, bool is_leq_upcall)

delete_entry

Delete a dataflow entry.

Note: either is_threshold_in_packets or is_threshold_in_bytes (or both) must be true. Note: either is_geq_upcall or is_leq_upcall (but not both) must be true.

Parameters:
sourcethe source address.
groupthe group address.
threshold_intervalthe dataflow threshold interval.
threshold_packetsthe threshold (in number of packets) to compare against.
threshold_bytesthe threshold (in number of bytes) to compare against.
is_threshold_in_packetsif true, threshold_packets is valid.
is_threshold_in_bytesif true, threshold_bytes is valid.
is_geq_upcallif true, the operation for comparison is ">=".
is_leq_upcallif true, the operation for comparison is "<=".

Returns: XORP_OK on success, otherwise XORP_ERROR.

int  delete_entry (const IPvX& source, const IPvX& group)

delete_entry

Delete all dataflow entries for a given source and group address.

Parameters:
sourcethe source address.
groupthe group address.

Returns: XORP_OK on success, otherwise XORP_ERROR.

int  delete_entry (MfeaDfe *mfea_dfe)

delete_entry

Delete a given MfeaDfe dataflow entry.

Parameters:
mfea_dfethe MfeaDfe dataflow entry to delete.

Returns: XORP_OK on success, otherwise XORP_ERROR.
