Abstract: Provided is a method and apparatus for searching for a Maintenance End Point (MEP), and a storage medium. The method includes that: a chip of the MEP parses an obtained packet; the chip of the MEP determines whether a field of the parsed packet matches a field in a combination of a port and a Virtual Local Area Network (VLAN); and in a case where the field of the parsed packet matches the field in the combination of the port and the VLAN, the chip of the MEP determines that the MEP is found successfully.

Abstract: A message processing method and device, a storage medium, and an electronic device are provided. The method includes: receiving a message to be processed by means of a Bidirectional Forwarding Detection (BFD) processing engine of a chip, the BFD processing engine storing head Maintenance End Points (MEP); if a head MEP corresponding to the message to be processed is not found in the BFD processing engine of the chip, judging whether to forward the message to be processed to a processor; and if a judgment result is yes, saving the information of the message in a client MEP in the processor. The problem in the related art that an MEP on a Head side in RFC8562 only transmits but does not receive a BFD message, an MEP on a Tail side only receives but does not transmits a BFD message and thus the requirements cannot be satisfied is resolved.

Abstract: Provided are a forwarding domain allocation method and device, a storage medium, and an electronic device. The method may includes: acquiring target messages from different input ports, the number of the acquired target messages being greater than or equal to the number of input ports; acquiring identifier information carried in the target message; and on the basis of the identifier information carried in the target message, allocating a forwarding domain to the target message.

Abstract: Provided is a Bidirectional Forwarding Detection (BFD) parameter negotiation method, apparatus and chip. The method includes that: a first apparatus sends a BFD negotiation packet to a second apparatus, the BFD negotiation packet carrying a first verification value; the first apparatus receives a BFD negotiation response packet returned by the second apparatus, the BFD negotiation response packet carrying a second verification value; the first apparatus checks whether the first verification value and the second verification value match each other, and determines whether negotiation of BFD parameters is an erroneous negotiation according to a checking result.

Abstract: Provided are a multicast message processing method and device, a storage medium and a processor. The method includes: a multicast group address is acquired from a received multicast message; according to the multicast group address, first routing information matching the multicast group address is searched in first data by means of a Hash algorithm; according to mark information and source address information of a multicast group, matched second routing information is searched in second data by means of the Hash algorithm; if the second routing information is found, the multicast message is sent according to next hop information of the multicast message in the second routing information; and if the second routing information is not found, the multicast message is sent according to the next hop information of the multicast message in the first routing information.

Abstract: The present disclosure provides recombinant microorganisms capable of sugar co-utilization, the recombinant microorganism comprising a genetically altered microorganism (e.g. S. cerevisiae) having a lack of, or reduced expression of, or expression of truncated or mutated forms of at least one polypeptide selected from Hxk1, Hxk2, and Glk1. Reduction of the expression or biological activity of Hxk1, Hxk2 and Glk1 leads to reduction in the glucose consumption pathway, allowing the microorganism to co-utilize multiple sugars (e.g. glucose, xylose, galactose) at an improved rate.
