Disclosed are a circuit unit, a circuit module and an apparatus for data statistics. The circuit unit comprises a first register and a second register, and stores data received via a first input terminal in the first register in a case where a first control terminal receives a valid control signal, stores data received via a second input terminal in the second register in a case where a second control terminal receives a valid control signal, and increases the value of data stored in the second register by 1 in a case where a third control terminal receives a valid control signal. The circuit module comprises one or more such circuit units, and the apparatus comprises one or more such circuit modules. The circuit module or the apparatus may use smaller resource and smaller power consumption to complete data statistics.

A method for establishing tunnels includes establishing a first unidirectional tunnel from a first node to a second node, and sending a first instruction for establishing a reverse tunnel of the first tunnel, when sending the first instruction to the second node, triggering the establishment of a second unidirectional tunnel from the second node to the first node, and binding the second tunnel to the first tunnel as the reverse tunnel of the first tunnel. A system for establishing tunnels is also provided. The establishment of a reverse tunnel may be automatically triggered after a forward tunnel is established, and a bidirectional tunnel is established.

A resource reservation method, a message sending method, a message receiving method, and a node apparatus in the field of network communication technology are provided. The resource reservation method includes the following steps. A resource reservation request message is received. A resource reservation value and additional accuracy information of the resource reservation value are recorded in the message. Bandwidth resources are reserved for a source node according to the additional accuracy information and the resource reservation value. Thus, resources can be reserved accurately and traffic loss caused by accuracy loss of reservation resources in the case of high traffic is avoided.
