Description
Technical Field
The invention relates to the field of realization of an Ethernet network processing chip integrated circuit, in particular to a method for realizing a low-rate port adaptive high-rate port in a direct forwarding mode.
Background
There are two ways of forwarding packets at the switching or routing nodes of a packet-switched network, one is store-and-forward and the other is cut-through forwarding. The storing and forwarding is to receive the whole message and then to perform the processing of message distribution, filtering, statistics, routing/switching and forwarding, etc. The store-and-forward method has a relatively large packet storage delay, for example, an ethernet packet of 1542 bytes is received at a gigabit rate, which takes 12.336us and has a relatively large delay. The through forwarding does not need to receive the whole message completely, and only needs to receive a part of the message, such as the first 14 bytes of the ethernet message or the first 64 bytes of the message, and the like, to start message processing, so that the packet storage delay of the message is greatly reduced, and meanwhile, the jitter caused by different message lengths can be reduced, and the method is often used in scenes requiring low delay or jitter, such as a TSN time sensitive network and the like.
Due to the problem of port rate adaptation, the direct forwarding mode cannot be realized from a low-rate port to a high-rate port, that is, when a packet is forwarded from the low-rate port to the high-rate port, the direct forwarding mode cannot be used, for example, a 100Mbps port forwards data to a 1Gbps port or a 1Gbps port forwards data to a 10Gbps port, and a common solution is to change the direct forwarding mode into a store-and-forward mode. But the store-and-forward mode necessarily brings a relatively large forwarding delay.

In order to solve the technical problem, the invention discloses a method for realizing the adaptation of a low-rate port to a high-rate port in a cut-through forwarding mode, which comprises the following steps: splitting a data link layer MAC layer of a high-rate port into a plurality of sub-MAC layers according to the number of low-rate ports, so that each low-rate port corresponds to one sub-MAC layer of one high-rate port; adding an MAC merging layer between an MAC layer and a physical layer (PHY) layer of the high-rate port, wherein each sub-MAC layer of the high-rate port is connected with the PHY layer through the MAC merging layer; dividing the bandwidth of a high-rate port into a plurality of time slots according to the rate grade of a low-rate port, wherein the rate of a logic communication link divided according to the time slots is equal to the access rate of the corresponding low-rate port, and the number of the time slots is equal to the number of the logic communication links; and the low-rate port sends data to a corresponding sub MAC layer of the high-rate port according to a rate consistency principle.
In a further technical scheme, received message fragments are forwarded to a sub-MAC layer of a high-rate port corresponding to a low-rate port from the low-rate port, the message fragments are packaged into Ethernet fragment messages by an MAC merging layer of the high-rate port, and the message fragments of each sub-MAC layer are forwarded according to time slots.
In a further technical scheme, when the message is packaged into the Ethernet fragment message in a fragment manner, the preamble of the message is modified, and the identification information of the logical link and the message fragment information are added.
In a further technical scheme, modifying a preamble of a packet and adding logical link identification information and packet fragmentation information includes: the method comprises the steps that an original lead code of 7 bytes of an Ethernet message is changed into 5 bytes, the 6 th byte of the original lead code is changed into a fragment start delimiter, the fragment start delimiter comprises a first fragment delimiter for indicating that the current fragment is a first fragment and a non-first fragment delimiter for indicating that the current fragment is a subsequent fragment, and the 7 th byte of the original lead code is changed into a channel identification ID for indicating a logic communication link where the fragments are located.
In a further technical solution, modifying the preamble of the packet, and adding the logical link identification information and the packet fragmentation information further includes: the method comprises the steps of changing an Ethernet message initial separator into a fragment effective data length to indicate the effective data length of a data field of the current Ethernet fragment message, filling data to 60 bytes when the last fragment data is less than 60 bytes, wherein the data field is used for storing message fragment contents, and a cyclic redundancy check code (CRC) is used for identifying the end of the fragment and the end of the message.
In a further technical scheme, the high-rate port sequentially sends out the data in each sub-MAC according to time slots and fragments, and receives the data information of each logical communication link according to time slots at the receiving end of the high-rate port and processes the message fragments.

As shown in fig. 1, VPN users access to a network at a gigabit GE rate and converge on a 10GE port, and then connect two networks through a 10GE link, and reduce forwarding delay by using a direct forwarding mode, where if the packet processing depth of the direct forwarding mode is 64 bytes (the packet is divided into 64 byte fragments), the packet storage delay of each hop of the packet is reduced to 512ns, thereby greatly improving network performance.
The design key points of the invention comprise:
(1) And splitting the MAC layer of the high-rate port into a plurality of sub-MACs according to the rate matching level.
(2) And adding a MAC merging layer between the MAC layer and the PHY layer of the high-rate port.
(3) The bandwidth of the high-speed port is divided into a plurality of time slots according to the rate grade of the low-speed port, namely, the high-speed channel is divided into a plurality of logical communication links according to the rate grade of the low speed.
(4) And the low-rate port sends data to the corresponding sub-MAC of the high-rate port according to the rate consistency principle.
