Step 1105: when the network equipment received message on a port, taxon received this message, and selected the Core unit from forward processing unit, and the message that receives is sent to selected Core unit.
Here, referring to Fig. 3, in the present invention, when network device internal comprises first order taxon and a plurality of second level taxon, the process of this step 1105 specifically comprises: by the message on the first order taxon reception network equipment port, this first order taxon is selected a second level taxon from the taxon of a plurality of second level then, and message is sent to selected second level taxon; This selected second level taxon is carried out the process of selecting the Core unit from forward processing unit when receiving message.Wherein,
First order taxon selects the specific implementation process of a second level taxon can include but not limited to following dual mode from the taxon of a plurality of second level:
Mode A, first order taxon are monitored the traffic load situation of each second level taxon in real time, and therefrom select the second level taxon of a current business load minimum;
Mode B, first order taxon are selected a second level taxon according to the partial session information of carrying in the message.Such as, for the message that carries particular source, first order taxon is selected second level taxon 1, and for the message that carries the specific purpose address, first order taxon is selected second level taxon 2 etc.
In this step 1105, taxon (when comprising first order taxon and a plurality of second taxon in the taxon, taxon described herein is the selected second level of a first order taxon taxon) selects the specific implementation process of Core unit to include but not limited to following mode from forward processing unit:
Mode one, select according to session under the message.
In this mode one, set in advance through the corresponding relation between the different sessions of the described network equipment and the different Core unit; When taxon receives message, determine the session under the message, according to set corresponding relation, from forward processing unit, select with message under the corresponding Core unit of session.
Preferably, transmit treatment effeciency, in the present invention,, can adopt mode one, select same Core unit that all messages of this session are transmitted processing for the session that needs order-preserving in order further to improve message; For the session that does not need order-preserving, can not adopt mode one, utilize different Core unit that all messages of this session are transmitted processing.Therefore, in this mode one, under taxon is determined message after the session, taxon can at first judge whether and need carry out order-preserving to session under the determined message, if, then continue described in the executive mode one according to set corresponding relation from forward processing unit, select with the step of the corresponding Core unit of definite session, otherwise, do not adopt mode one, and adopt other modes to select the Core unit.
Wherein, described taxon judges whether and need the implementation procedure that order-preserving is carried out in session under the determined message be comprised:
Described taxon is judged that the described network equipment is follow-up and need whether be had the order-preserving requirement to the processing that described message carries out, if, then assert and to carry out order-preserving to session under the determined message, otherwise assert does not need order-preserving is carried out in session under the determined message;
Perhaps, set in advance the session information that does not need order-preserving, whether the taxon judgement can find the session information under the determined message in the set session information that does not need order-preserving, if can not find, then determine and to carry out order-preserving to session under the determined message, if can find, then determining does not need order-preserving is carried out in session under the determined message.Wherein, described setting do not need order-preserving session information implementation procedure can for: in advance according to actual business requirement, the session information that does not need order-preserving directly is set in taxon; Or, any one Core unit is after initially receiving previous or several messages of a session, according to the characteristic information that carries in the message, whether the message of judging this session arrives in proper order, if order does not arrive, the message of then determining this session does not need order-preserving, the information of this session is carried in the non-order-preserving notice is sent to taxon; Taxon is provided with the not session information of needs order-preserving according to the non-order-preserving notice that receives.
In this mode one, taxon determines that the process of the affiliated session of message comprises: when the message that receives was the IPv4 message, taxon was determined the session that message is affiliated according to five-tuple that carries in the message (source IP address, purpose IP address, protocol type, source port number and destination slogan) and private network index information; When the message that receives was the IPv6 message, taxon was determined session under the message according to the source IP address that carries in the message and flow label information; When the message that receives was the multiprotocol label switching (mpls) message, taxon was determined session under the message according to the outermost layer label information that carries in the message; When the message that receives was two layers of exchange of Ethernet message, taxon was determined the session that message is affiliated according to medium access control (MAC) address, source of carrying in the message and target MAC (Media Access Control) address information.
Mode two, select according to the traffic load situation of each Core unit in the forward processing unit.
In this mode two, taxon is monitored the service load quantity of each Core unit in real time; In this step, taxon is selected the Core unit of current business load minimum from forward processing unit.
Mode three, taxon are selected the Core unit arbitrarily from forward processing unit.
Step 1106: the control information that selected Core unit is sent according to control Core, the message that receives is carried out message transmit processing.
Here, described message is transmitted and is treated to prior art, but can be exemplified as: the skin forwarding processing first time, internal layer transmit processing and the skin forwarding second time is handled.
