  • Patent number: 10735309
    Abstract: A packet processing method includes: a traffic classifier receives a first packet; the traffic classifier determines, in policy information in the traffic classifier and according to a first filtering rule that matches the first packet, a first service identifier that matches the first filtering rule, and an address, which matches the first filtering rule, of a first service routing trigger. The traffic classifier sends a second packet to the first service routing trigger. Where the policy information includes: a filtering rule, an address of a service routing trigger, and a service identifier corresponding to the filtering rule. Where the filtering rule is used to identify a packet, and the service identifier is used to represent a sequence of a service node that processes the packet. Where the second packet is formed by adding the first service identifier to the first packet.

  • Publication number: 20190182145
    Abstract: An information management method includes that a controller generates a first message carrying an address of a first next hop of a network device. The first message includes first identification information. The first identification information instructs the network device to delete, from a next hop table stored in the network device, an entry of the first next hop corresponding to the address of the first next hop. The network device receives the first message, and deletes the entry of the first next hop as indicated by the first identification information. The controller withdraw an unavailable next hop by separately sending information about the next hop to the network device without route prefix information, effectively saving a system resource occupied for route withdrawal message exchanging between the controller and the network device, and improving service processing efficiency.

  • Publication number: 20190182152
    Abstract: An information synchronization method includes sending, by a controller, a first message to a network device, where the first message carries control routing protocol (CRP) routing entry information, and is used to advertise a CRP route, and the first message includes first identification information, and after receiving the first message, storing, by a forwarding device, the CRP routing entry information into a CRP routing table of the network device as indicated by the first identification information. Hence, because a route advertised by the controller and a route advertised using a routing protocol between forwarding devices are stored in different routing tables, a related application of the route advertised using the routing protocol between the forwarding devices is not affected.

  • Patent number: 7399812
    Abstract: The present invention relates to silicon ether compounds having a general formula (I), a method for the preparation thereof and use thereof as a component of catalysts for polymerization of olefins. In particular, in propylene polymerization, catalyst systems comprising the silicon ether compounds as external electron donor component exhibit good hydrogen response, and can be used to prepare polymer having high isotacticity at high yield. wherein R1-R10 groups are as defined in the description.

  • Patent number: 6822109
    Abstract: The present invention relates to a silicon ether compound having general formula (I): wherein, R and R1-R10 groups, which may be Identical or different, represent hydrogen, halogen, C1-C20 linear or branched alkyl, C3-C20 cycloalkyl, C8-C20 aryl, C7-C20 alkaryl or C7-C20 aralkyl group, and two or more R groups can be linked to form saturated or unsaturated condensed ring structure which is optionally substituted by a group having the same meanings with that of R1, R and R1-R10 groups optionally contain one or more hetero-atoms replacing carbon atom, hydrogen atom or the both, said heteroatom is selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus and halogen atom, and A represents carbon atom or silicon atom. The present invention also relates to a method for the preparation of the silicon ether compounds of general formula (I) and a process for polymerization of olefins.
