  • Publication number: 20200403914
    Abstract: This application provides a packet sending method. The method includes: receiving, by a target service node, a first packet sent by a client, where a destination address of the first packet is an IP address of a server; sending, by the target service node, a second packet to the client, where the second packet includes an IP address of the target service node; and receiving, by the target service node, a third packet sent by the client, where a destination address of the third packet is the IP address of the target service node. The client changes a destination address from the IP address of the server to the IP address of the target service node to send the third packet, and the server directly forwards the third packet to the target service node with no need to record a correspondence between the client and the target service node.

  • Patent number: 10798760
    Abstract: The method includes: receiving, by a first forwarding device, a first control packet sent by a control device, where the first control packet carries N pieces of control information and N network slice identifiers, the N pieces of control information are in a one-to-one correspondence with the N network slice identifiers, where i?[1, N], and N?1; determining, by the first forwarding device, M pieces of first control information from the N pieces of control information based on the N network slice identifiers, where the M pieces of first control information are in a one-to-one correspondence with M first network slices, and the M first network slices are borne on the first forwarding device, where M?1; and controlling, by the first forwarding device, a first network slice j based on first control information j, where j?[1, M]. This application can reduce processing burden of the control device.

  • Publication number: 20200062792
    Abstract: A method for preparing high-purity D-psicose, comprising the following steps: (1) centrifuging a fermentation broth of Bacillus subtilis, and then subjecting the bacteria to homogenization to obtain a mixed solution containing D-psicose 3-epimerase; (2) preparing a fructose solution, adding the mixed solution containing D-psicose 3-epimerase to the fructose solution, adjusting the pH, adding cobalt chloride thereto, and performing the reaction at a certain temperature; and feeding the fructose solution to the reaction solution, continuing the reaction, and stopping the reaction, obtaining a crude D-psicose solution; and (3) subjecting the crude D-psicose solution to decolorization, filtration, ion exchange, chromatographic separation, concentration, and then crystallization or drying, obtaining D-psicose.

  • Publication number: 20190372881
    Abstract: A method for implementing network virtualization, and a related apparatus and a communications system are provided. The method for implementing network virtualization may include: receiving, by an SDN controller, a virtual network creation request that carries virtual network topology information; creating a virtual network in response to the virtual network creation request; establishing, by the SDN controller, a device mapping relationship; establishing, by the SDN controller, a port mapping relationship; allocating, by the SDN controller, a virtual SDN controller to the virtual network; and registering, by the SDN controller, a first virtual forwarding device and a second virtual forwarding device with the virtual SDN controller. Technical solutions of embodiments of the present invention help to improve networking flexibility, reduce service costs, and shorten a service deployment period.

  • Patent number: 10479840
    Abstract: A resistant dextrin and a method for preparing the same. In the resistant dextrin, molar content of DP1 is smaller than or equal to 1%, molar content of DP2 is smaller than or equal to 4.5%, molar content of DP3 is smaller than or equal to 7.0%, an average degree of polymerization is 6-12, a pH value is 3.0-6.0, and molar content of dietary fibers is greater than or equal to 85%. The present invention further relates to a method for preparing the resistant dextrin. Since the present invention uses starch as the raw material and divides dextrinization reaction into two stages for the first time, the degree of polymerization of the polymerization reaction is reliably guaranteed, the number of caused side reactions is decreased at the same time and the difficulty in subsequent purification treatment is greatly decreased.
