In application embodiment, after obtaining characteristic information, the first equipment can determine the report to match with characteristic information Literary (i.e. object message), that is, the feature that the characteristic information and the first equipment that carry in object message are received from the second equipment Information matches, and object message is the message of forward-path to be adjusted.

S203: whether the interface that judgement is currently used in forwarding object message is aggregation interface, if so, executing S204.

In application embodiment, after determining object message, the first equipment, which can determine, is currently used in forwarding object message Interface (being properly termed as target interface), and judge whether target interface is aggregation interface.Specifically, will be in subsequent embodiment It is discussed in detail.

S204: other interface for being used to forward object message being revised as in aggregation group belonging to current interface connect Mouthful.

In application embodiment, when the first equipment determines that being currently used in the interface of forwarding object message is aggregation interface, The interface for being used to forward object message can be revised as other interfaces in aggregation group belonging to current interface by the first equipment. First equipment can then be forwarded object message by other interfaces in aggregation group belonging to current interface, so that mesh Mark message no longer passes through the link of script congestion, can reduce the probability of network service interruption

Due to the first equipment the mode that object message is forwarded can be it is diversified, the first equipment can To determine target interface by different modes, and then judge whether target interface is aggregation interface.

Optionally, may include in outer layer feature information virtual LAN (Virtual Local Area Netwo rk, VLAN it) identifies.Correspondingly, the source MAC (Media Access C ontrol, media access control) in outer layer characteristic information In the case that address (being properly termed as outer layer source MAC) is not the MAC Address of itself, S203 be may comprise steps of:

It will go out connecing with the target MAC (Media Access Control) address and the MAC forwarding-table item that matches of VLAN mark in outer layer feature information Mouthful, it is determined as being currently used in the interface of forwarding object message, and judge to be currently used in whether the interface of forwarding object message is poly- Splice grafting mouth.

In application embodiment, after obtaining outer layer feature information, the first equipment can be obtained from outer layer feature information Outer layer source MAC, then, the first equipment may determine that whether outer layer source MAC is itself MAC Address.

When the first equipment determines that outer layer source MAC is not the MAC Address of itself, the first equipment can be determined for mesh Message is marked as double layer network forwarding, (is properly termed as outer at this point, the VLAN in the available outer layer feature information of the first equipment is identified Layer VLAN mark), and then can determine with the target MAC (Media Access Control) address in outer layer feature information (with being properly termed as outer layer purpose MAC Location) and the MAC forwarding-table item (being properly termed as the first MAC forwarding-table item) that matches of outer VLAN identification, and the first MAC is forwarded Outgoing interface in list item is determined as target interface, and then may determine that whether target interface is aggregation interface.

Above-mentioned VLAN mark can be VLAN Tag (label), for identifying different VLAN.

Correspondingly, the first equipment can be by the first MAC forwarding table when the first equipment determines target interface for aggregation interface Outgoing interface in, other interfaces being revised as in aggregation group belonging to target interface.

For example, the first current MAC forwarding-table item may refer to table (1).

Table (1)

Target MAC (Media Access Control) address	VLAN mark	Forwarding label	Outgoing interface
				MAC1	VLAN1	\	Aggregation group 1

In table (1), with outer layer target MAC (Media Access Control) address be MAC1 and outer VLAN identification is belonging to the corresponding outgoing interface of VLAN1 Aggregation group be aggregation group 1, due to currently forward be labeled as " ", that is, for outer layer target MAC (Media Access Control) address be MAC1 and outer layer VLAN is identified as the message of VLAN1, and the first equipment can forward the message by any outgoing interface in aggregation group 1.

If target interface is the corresponding interface of link L12 in Fig. 1, aggregation group 1 belonging to target interface further includes other Interface, then the first equipment can modify to the first MAC forwarding-table item of table (1), obtain table (2).

Table (2)

Target MAC (Media Access Control) address	VLAN mark	Forwarding label	Outgoing interface
				MAC1	VLAN1	Disable L12	Aggregation group 1

It is MAC1 for outer layer target MAC (Media Access Control) address and message that outer VLAN identification is VLAN1, first sets based on table (2) Standby then the message will not be forwarded by the corresponding interface of link L12, the first equipment can pass through other interfaces in aggregation group 1 and turn The message is sent out, causes the second equipment to abandon the message to avoid link congestion, and then the probability of network service interruption can be reduced.

In addition, the first equipment can determine characteristic information if not including in outer envelope information has VLAN mark The message that message is untag (removing label) is issued on incoming interface, and is identified according to the corresponding VLAN of the message and determined that the first MAC turns Forwarding list item.

When the first equipment determines that target interface is not aggregation interface, the first equipment can will be used to forward and outer layer purpose The MAC forwarding-table item for the message that MAC Address and outer VLAN identification match is revised as current MAC forwarding-table item (i.e. first MAC forwarding-table item) list item of equal value or backup list item.

It is understood that even if target interface is aggregation interface, but aggregation group belonging to target interface does not include it He allow using interface, that is, other interfaces in aggregation group belonging to target interface in addition to target interface are all prohibited from using, Then the first equipment can also will be used to forward the MAC of the message to match with outer layer target MAC (Media Access Control) address and outer VLAN identification to turn Forwarding list item is revised as the list item of equal value or backup list item of the first MAC forwarding-table item.

Specifically, if target interface is not aggregation interface, alternatively, if target interface is aggregation interface, but target Aggregation group belonging to interface do not include other allow using interface, then the first equipment may determine that the first MAC forwarding-table item is It is no to there is list item of equal value.

When the first equipment determines that the first MAC forwarding-table item has list item of equal value, the first equipment can be forwarded the first MAC The list item of equal value of list item is determined as the message for being currently used in forwarding and outer layer target MAC (Media Access Control) address and outer VLAN identification matches MAC forwarding-table item.

When the first equipment determines that list item of equal value is not present in the first MAC forwarding-table item, the first equipment can turn the first MAC The backup list item of forwarding list item is determined as the report for being currently used in forwarding and outer layer target MAC (Media Access Control) address and outer VLAN identification matches The MAC forwarding-table item of text.

In addition, may include encapsulation format information (being properly termed as outer envelope format information) in outer layer feature information, the One equipment can judge whether target interface is aggregation interface according to outer envelope format information.

Optionally, in the case that the source MAC in outer layer characteristic information is the MAC Address of itself, S203 be can wrap Include following steps:

Step 1, if the encapsulation format information in outer layer feature information indicates Internet protocol IP (Internet Protocol, IP) encapsulation, and the source IP address in outer layer feature information is not the IP address of itself, it will be with outer layer feature information In the fast-turn construction list item that matches of five-tuple in outgoing interface, be determined as being currently used in the interface of forwarding object message, and judge Whether the interface for being currently used in forwarding object message is aggregation interface.

In application embodiment, when the first equipment determines that outer layer source MAC is the MAC Address of itself, the first equipment Available outer envelope format information, to determine outer envelope format.If in outer layer feature information including destination IP Location and source IP address (being properly termed as outer layer source IP address), the first equipment can determine outer envelope format for IP encapsulation.

If outer layer source IP address is not the IP address of itself, the first equipment can by with five yuan in outer layer feature information The outgoing interface in fast-turn construction list item that group matches, is determined as target interface, and then may determine that whether target interface is that polymerization connects Mouthful.

Correspondingly, the first equipment can will be believed with outer layer feature when the first equipment determines target interface for aggregation interface The outgoing interface in fast-turn construction list item that five-tuple in breath matches, other being revised as in aggregation group belonging to target interface connect Mouthful.

Wherein, the fast-turn construction list item to match with the five-tuple in outer layer feature information, i.e., with the source in outer layer feature information The homogeneous matched fast-turn construction list item of IP address, purpose IP address, source port number, destination slogan and protocol type.

In addition, when the first equipment determines that target interface is not aggregation interface, the first equipment can will be used to forwarding with it is outer The route table items for the message that purpose IP address (being properly termed as outer layer purpose IP address) in layer characteristic information matches, are revised as The list item of equal value or backup list item of current route table items (being properly termed as the first route table items).

It is understood that even if target interface is aggregation interface, but aggregation group belonging to target interface does not include it He allow using interface, that is, other interfaces in aggregation group belonging to target interface in addition to target interface are all prohibited from using, Then the first equipment will can also be used to forward the route table items of the message to match with outer layer purpose IP address, be revised as the first via By the list item of equal value or backup list item of list item.

Alternatively, when the first equipment determines that the fast-turn construction list item to match with the five-tuple in outer layer feature information is not present, First equipment will can also be used to forward the route table items of the message to match with outer layer purpose IP address, be revised as the first via by The list item of equal value or backup list item of list item.

In this step, after determining the first route table items, the first equipment may determine that the first route table items whether there is Valence list item.

When the first equipment determines that the first route table items have list item of equal value, the first equipment can be by the first route table items List item of equal value is determined as being currently used in the route table items for the message that forwarding matches with outer layer purpose IP address.

When the first equipment determines that list item of equal value is not present in the first route table items, the first equipment can be by the first route table items Backup list item, be determined as being currently used in forwarding and the route table items of message that outer layer purpose IP address matches.

Step 2, if source IP address in outer layer feature information is the IP address of itself, and characteristic information includes to the One message carries out inner layer features information when internal layer encapsulation, and according to inner layer features information, judgement is currently used in forwarding object message Interface whether be aggregation interface.

In application embodiment, if outer layer source IP address is the IP address of itself, the first equipment may determine that feature is believed Inner layer features information when whether breath includes to the progress internal layer encapsulation of the first message.When the first equipment determines that characteristic information includes interior When layer characteristic information, the first equipment can judge whether be currently used in the interface for forwarding object message according to inner layer features information For aggregation interface.Specifically, will be discussed in detail in subsequent embodiment.

Optionally, in the case where outer layer source MAC is the MAC Address of itself, S203 be may comprise steps of:

If the encapsulation format information in outer layer feature information indicates MPLS (Multi-Protocol Label Switching, multiprotocol label switching) encapsulation, by with the target MAC (Media Access Control) address and MPLS outgoing label phase in outer layer feature information The outgoing interface in MPLS forwarding-table item matched is determined as being currently used in the interface of forwarding object message, and judges to be currently used in and turn Whether the interface for sending out object message is aggregation interface.

In application embodiment, if outer layer source MAC is the MAC Address of itself, and include in outer layer feature information Have MPLS outgoing label (being properly termed as outer layer MPLS outgoing label), the first equipment can determine outer envelope format for MPLS encapsulation. First equipment can determine that the MPLS forwarding-table item to match with outer layer MPLS outgoing label and outer layer target MAC (Media Access Control) address (can claim For the first MPLS forwarding-table item).Outgoing interface in first MPLS forwarding-table item can be determined as target interface by the first equipment, into And it may determine that whether target interface is aggregation interface.

Correspondingly, if target interface is aggregation interface there is list item of equal value and/or backup in i.e. the first MPLS forwarding-table item List item.First equipment will can be used to forward the message to match with outer layer MPLS outgoing label and outer layer target MAC (Media Access Control) address MPLS forwarding-table item is revised as the list item of equal value or backup list item of the first MPLS forwarding-table item.

In this step, after determining the first MPLS forwarding-table item, the first equipment may determine that the first MPLS forwarding-table item is It is no to there is list item of equal value.

When the first equipment determines that the first MPLS forwarding-table item has list item of equal value, the first equipment can turn the first MPLS The list item of equal value of forwarding list item is determined as being currently used in what forwarding matched with outer layer MPLS outgoing label and outer layer target MAC (Media Access Control) address The MPLS forwarding-table item of message.

When the first equipment determines that list item of equal value is not present in the first MPLS forwarding-table item, the first equipment can be by the first MPLS The backup list item of forwarding-table item, is determined as being currently used in forwarding and matches with outer layer MPLS outgoing label and outer layer target MAC (Media Access Control) address Message MPLS forwarding-table item.

Optionally, inner layer features information may include VPN (Virtual Private Network, Virtual Private Network) Mark.

Source MAC (being properly termed as internal layer source MAC) in internal layer characteristic information is not the MAC Address of itself In the case of, for the first equipment according to inner layer features information, whether the interface that judgement is currently used in forwarding object message is aggregation interface, It may comprise steps of:

It will go out connecing with the target MAC (Media Access Control) address and the MAC forwarding-table item that matches of VPN mark in inner layer features information Mouthful, it is determined as being currently used in the interface of forwarding object message, and judge to be currently used in whether the interface of forwarding object message is poly- Splice grafting mouth.

Wherein, VPN mark can carry for VPN ID if there are VXLAN encapsulation for internal layer in inner layer features information VXLAN ID, then the first equipment can determine that VPN is identified according to the VXLAN ID；If there are GRE (Generic for internal layer Routing Encapsulation, Generic Routing Encapsulation) encapsulation, i.e., it is (close GRE Key to be carried in inner layer features information Key), then the first equipment can determine that VPN is identified according to the GRE Key.

In application embodiment, after obtaining inner layer features information, the available internal layer source MAC of the first equipment, so Afterwards, the first equipment may determine that whether internal layer source MAC is itself MAC Address.

When the first equipment determines that internal layer source MAC is not the MAC Address of itself, the available VPN mark of the first equipment Know, and by in inner layer features information target MAC (Media Access Control) address (being properly termed as internal layer target MAC (Media Access Control) address) and VPN identify match MAC forwarding-table item (being properly termed as the 2nd MAC forwarding-table item) in outgoing interface, be determined as target interface, and then may determine that Whether target interface is aggregation interface.

Correspondingly, the first equipment can be by the 2nd MAC forwarding table when the first equipment determines target interface for aggregation interface Outgoing interface in, other interfaces being revised as in aggregation group belonging to target interface.

In addition, when the first equipment determine target interface be not aggregation interface when, the first equipment can will be used for forward with it is interior The MAC forwarding-table item of message that layer target MAC (Media Access Control) address and VPN mark match is revised as current MAC forwarding-table item (i.e. the Two MAC forwarding-table items) list item of equal value or backup list item.

It is understood that even if target interface is aggregation interface, but aggregation group belonging to target interface does not include it He allow using interface, that is, other interfaces in aggregation group belonging to target interface in addition to target interface are all prohibited from using, Then the first equipment will can also be used to forward the MAC forwarding table of the message to match with internal layer target MAC (Media Access Control) address and VPN mark , it is revised as the list item of equal value or backup list item of the 2nd MAC forwarding-table item.

Specifically, if target interface is not aggregation interface, alternatively, if target interface is aggregation interface, but target Aggregation group belonging to interface do not include other allow using interface, then the first equipment may determine that the 2nd MAC forwarding-table item is It is no to there is list item of equal value.
