Problems solved by technology

[0004] However, at present, for many hardware chips such as MRVL chips, etc., the LPM table on it does not support SEBP and DEBP (also known as the LPM table subdivision of the EBP to which the IP address belongs), which makes micro-segmentation impossible.

Embodiment 1

[0070] Embodiment 1 is applied to an IPv4 scenario. In this IPv4 scenario, the source IP address and the destination IP address of a packet are two different IPv4 addresses.

[0071] When a network device such as a VTEP receives a packet sent by a local host (recorded as the source host), such as figure 2 As shown, the TTI engine uses the source IP address of the packet as a keyword and searches the TCAM table for the EPG corresponding to the keyword according to the longest match principle, and determines the found EPG as the SEPG.

[0072] Afterwards, the IPCL engine uses the destination IP address of the message as a keyword and searches for the EPG corresponding to the keyword in the TCAM table according to the longest match principle, and determines the found EPG as the DEPG.

[0073] Afterwards, as an embodiment, the IPCL engine uses SEPG and DEPG as keywords to search for GBP whose matching condition is the keyword. Or, as another embodiment, the virtual private netwo...

Embodiment 2

[0077] Embodiment 2 is applied to an IPv6 scenario. In this IPv6 scenario, the source IP address and the destination IP address of the message are two different IPv6 addresses. The IPv6 address is 128 bits, which is 4 times higher than the 32-bit IPv4 address. However, the TTI engine only supports 30 bytes, which leads to the fact that the TTI engine cannot fully match the 128-bit IPv6 address when using the TTI engine to find the SEPG that matches the source IP address. Based on this, in this embodiment, the 128-bit source IP address (128-bit IPv6 address) can be converted into a 48-bit MAC address to save TTI resources.

[0078] Specifically, when a network device such as a VTEP receives a message sent by a local host (recorded as the source host), as in image 3 As shown, the TTI engine first determines that the IP address is the source MAC address of the source host of the source IP address in the packet. Optionally, in this embodiment, the TTI engine can find the MAC ad...

Abstract

The invention provides a message forwarding control method and device and electronic equipment. In the application, when hardware chips such as an MRVL chip and the like do not support an LPM table originally used for message three-layer forwarding to realize micro-segmentation by SEBP and DEBP, the network device realizes micro-segmentation and GBP by a TCAM table originally not used for messagethree-layer forwarding, so as to realize message forwarding control; in this way, micro-segmentation can be achieved on the premise that hardware chips such as an MRVL chip do not support LPM tables on the hardware chips to be divided into SEBP and DEBP.

Description

technical field [0001] The present application relates to network communication technology, in particular to a message forwarding control method, device and electronic equipment. Background technique [0002] Micro-segmentation, also known as security isolation based on fine-grained grouping, means that servers in the data center network are grouped according to certain principles, and then traffic control policies are deployed based on grouping, so as to achieve the purpose of simplifying operation and maintenance and security management and control. [0003] In network applications, micro-segmentation is implemented based on the Longest Prefix Matching hardware Layer 3 switching (LPM: Longest PrefixMatching) table. Specifically, a source endpoint group (SEBP: Source End PointGroup) and a destination endpoint group (DEBP: Destination End Point Group) can be classified in the LPM table. Here, SEBP refers to the EBP to which the source IP address is assigned, and DEBP refers...
