Reason layer connection the 3rd time slots of PHY6 are sent out.Pair for the time slot that the time slot of receiving side physical layer connection is connect with sending side physical layer
Should be related to can be fixed, thus intermediary network device 200 can determine transmission according to the time slot that receiving side physical layer connects
The time slot of side physical layer connection.Optionally, each time slot and hair of each physical layer connection of receiving side are recorded by mapping table
Send the correspondence of a time slot of each physical layer connection in side.
Fig. 4 is the flow diagram of data forwarding method in a kind of FlexE provided by the embodiments of the present application.Side described in Fig. 4
Method can be applied to equipment shown in Fig. 2, and execute data forwarding shown in Fig. 3.
S401, the first time slot that intermediary network device 200 is connected in the first physical layer receive the number that network equipment A is sent
According to.
For example, referring to Fig. 3, the 1st time slot reception network that intermediary network device 200 connects PHY1 in physical layer is set
The data a that standby A is sent can also be the data b for connecting the 1st time slot reception network equipment A of PHY2 in physical layer and sending,
Can be the data c for connecting the 2nd time slot reception network equipment A of PHY3 in physical layer and sending.
S402, intermediary network device 200 determine that the second physical layer connects according to the first time slot that first physical layer connects
The second time slot connect.
For example, referring to Fig. 3, the 1st time slot that intermediary network device 200 connects PHY1 according to physical layer determines physics
The 1st time slot of layer connection PHY5 can also be to determine that physical layer connects PHY6 according to the 1st time slot of physical layer connection PHY2
The 2nd time slot, can also be when connecting the 2nd time slot of PHY3 according to physical layer to determine that physical layer connects the 3rd of PHY6
Gap.The corresponding pass of first time slot of the first physical layer of above receiving side connection and the second time slot that the second physical layer of sending side connects
System can be fixed, and thus intermediary network device 200 can determine the second object according to the first time slot that the first physical layer connects
Manage the second time slot of layer connection.
Optionally, intermediary network device 200 record in the mapping table each time slot of receiving side each physical layer connection with
The correspondence of one time slot of each physical layer connection in sending side.Physics when intermediary network device 200 is according to reception data
The time slot of layer connection searches the mapping table, thereby determines that the time slot of physical layer connection to be used when transmission data.The mapping
May include reception time slot mark (such as the 1- in Fig. 3 of each time slot for identifying receiving side each physical layer connection in table
1,2-1,3-2), the sending time slots mark of each time slot for identifying sending side each physical layer connection (such as 5-1 in Fig. 3,
6-2,6-3) and receive time slot mark and sending time slots mark correspondence.Time slot mark 1-1, the 1st number are received in Fig. 3
Word " 1 " can be used for identifying the 1st physical layer connection PHY1, and the 2nd number " 1 " can be used for identifying the 1st time slot, thus mark
The 1st time slot of PHY1 can be identified by knowing 1-1.Similarly, the 2nd physical layer company can be identified by receiving time slot mark mark 2-1
The 1st time slot of PHY2 is connect, the 2nd time slot of the 3rd physical layer connection PHY3 can be identified by receiving time slot mark mark 3-2.
The above naming method for receiving time slot mark by way of example only, can be with other modes.Such as number may be used into rower
Know, 20 time slots of PHY1 can be identified as digital 1-20, and 20 time slots of PHY2 can be identified as digital 21-40, PHY3's
20 time slots can be identified as digital 41-60.The naming method of sending time slots mark is similar with time slot mark is received, herein no longer
It repeats.The correspondence for receiving time slot mark and sending time slots mark, such as record identification 1-1 and mark can be recorded in mapping table
Know 5-1 to correspond to, mark 2-1 is corresponding with mark 6-2, and mark 3-2 is corresponding with mark 6-3.
Based on the above mapping table and naming method, the 1st time slot that intermediary network device 200 connects PHY1 in physical layer is received
It is determining to receive time slot mark 1-1 when to data, mark 1-1 is found in the mapping table and corresponds to mark 5-1, and being determined by mark 5-1 will
Time slot to be used is the 1st time slot that physical layer connects PHY5.Similarly, intermediary network device 200 is connected according to physical layer
The 1st time slot of PHY2 can determine the 2nd time slot of physical layer connection PHY6, when connecting the 2nd of PHY3 according to physical layer
Gap can determine the 3rd time slot of physical layer connection PHY6.
S403, the second time slot that intermediary network device 200 is connected in second physical layer is to described in network equipment B forwardings
Data.
Intermediate equipment 200 is received in the second time slot of S402 the second physical layer connections determined to network equipment B forwardings
Data.For example, the data a that intermediate equipment 200 is received in physical layer connection the 1st time slot of PHY1 in Fig. 3, connects in physical layer
It connects the 1st time slot of PHY5 and is sent to network equipment B, the data b network equipment B that the 1st time slot of PHY2 receives are connected in physical layer,
It is sent to network equipment B in physical layer connection the 2nd time slot of PHY6, in the data that physical layer connection the 2nd time slot of PHY3 receives
C is sent to network equipment B in physical layer connection the 3rd time slot of PHY6.
By the data that will directly be received on the time slot that a receiving side physical layer connects above, in sending side one
The method that one time slot of a physical layer connection is forwarded, intermediary network device need not package, according to packet attribute into
2 layers and 3 layers dispatch deal of row Ethernet and packet carried out again the operation such as to be sliced, so as to reduce in intermediary network device
Processing time helps to reduce the Forwarding Delay in intermediate equipment.
Optionally, the above first physical layer connection belongs to the first FlexE groups, and the first FlexE groups include multiple from net
The physical layer of network device A to intermediary network device 200 connects, such as including PHY1, PHY2 and PHY3 in Fig. 3.Above second object
Reason layer connection belongs to the 2nd FlexE groups, and the 2nd FlexE groups include multiple from intermediary network device 200 to network equipment B's
Physical layer connects, such as PHY4, PHY5 and PHY6 in Fig. 3.Multiple physical layers can be connected and be bundled to provide by FlexE groups
A variety of traffic rates end to end, the scheme for being applied to FlexE groups have better applicability.
Optionally, it in the above mapping table may include first identifier set and second identifier set.In first identifier set
Each of a time slot being connected for identify a physical layer in the first FlexE groups of mark, it is every in second identifier set
A time slot of a mark for identifying the connection of a physical layer in the 2nd FlexE groups.First identifier set may include
The mark of all time slots of all physical layer connections in one FlexE groups, can also include physical layer company in part in the first FlexE groups
The mark of the partial time slot connect, such as including mark 1-1, the mark 2-1 and mark 3-2 in Fig. 3.Second identifier set can wrap
The mark for including all time slots of all physical layer connections in the 2nd FlexE groups can also include part physical in the 2nd FlexE groups
The mark of the partial time slot of layer connection, such as including mark 5-1, the mark 6-2 and mark 6-3 in Fig. 3.Further, it is reflecting
The correspondence that each of first identifier set mark and a mark in second identifier set can be recorded in firing table, by
This intermediary network device can be determined according to a time slot of the physical layer connection in the first FlexE groups for receiving data
The mark for receiving time slot determines the mark of sending time slots according to the identifier lookup mapping table for receiving time slot, according to sending time slots
