Constructor Details

#initialize(options = {}) ⇒ TableStatsReply

Information about tables that a switch supports. A switch may choose to maintain a single table that can store both wildcard and exact match flows. Or may use separate tables for each flow type. A user would not explicitly instantiate a Trema::TableStatsReply object but would be created as a result of parsing the OFPT_STATS_REPLY(OFPST_TABLE) message.

Returns an object that encapsulates the OFPST_STATS_REPLY(OFPST_TABLE) OpenFlow message.

Examples:

TableStatsReply.new(
  :table_id => 0,
  :name => "classifier",
  :wildcards => 4194303,
  :max_entries => 1048576,
  :active_count => 4,
  :lookup_count => 4,
  :matched_count => 0
)

Parameters:

• options (Hash) (defaults to: {}) —

  the options to create this instance with.

Options Hash (options):

• :table_id (Number) —

  a number that uniquely identifies the table.

• :name (String) —

  a meaningful name for the table.

• :wildcards (Number) —

  wildcards that supported by the table.

• :max_entries (Number) —

  the maximum number of flow entries the table can support.

• :active_count (Number) —

  number of active entries.

• :lookup_count (Number) —

  a counter of the number of packets looked up in the table.

• :matched_count (Number) —

  a counter of the matched hit entries.
