Publication number: 20150304218Abstract: The present invention provides a control channel establishing method, a forwarding point, and a controller. The method includes: sending, by a first FP, topology information of the first FP to a second FP by using the LLDP; receiving, by the first FP, first routing information that is sent by the controller and is used by the first FP to reach the controller, where the first routing information is generated by the controller according to the topology information of the first FP; and establishing, by the first FP, a second control channel with the controller according to the first routing information. The first FP does not need to run the IGP protocol, thereby avoiding that the first FP maintains an IGP neighbor relationship; moreover, the first FP does not need to store routing information for reaching another FP, which helps save storage resources and helps improve forwarding performance.Type: ApplicationFiled: July 6, 2015Publication date: October 22, 2015Inventors: Jun Wang, Tao Bai

Publication number: 20150241388Abstract: An improved staining method and system is described for staining a biopolymer such as a peptide, a protein, an RNA, a DNA, an oligosaccharide or a complex containing a peptide, a protein, an RNA, a DNA, or an oligosaccharide in a matrix. The method includes the step of moving a staining reagent into the matrix using an electric force. The staining time can be dramatically reduced relative to conventional technologies. The improved staining method can particularly be used, for example, to stain proteins after gel separation. Other related methods, related kits and related systems for carrying out the staining method are also described.Type: ApplicationFiled: May 7, 2015Publication date: August 27, 2015Inventors: Hong QIAN, Xin CHEN, Hongfei REN, Tao BAI, Fang Liang ZHANG

Patent number: 9061236Abstract: A device for gel electrophoresis is provided having larger wells for loading an increased sample volume with improved gel resolution. The device includes a gel cassette having a front plate and a back plate, wherein at least one plate has a stepped inner surface to create a wider opening at the top of the gel cassette, a gel matrix, and a comb with teeth having a thickness substantially equal to the spacing at the top opening of the gel cassette. Using this device, the sample volume in each well can be increased and the sample height in each well can be significantly reduced, as compared to loading the same volume in the wells of a standard gel cassette.Type: GrantFiled: November 20, 2012Date of Patent: June 23, 2015Assignee: Nanjingjinsirui Science & Technology Biology CorporationInventors: Zhuying Wang, Hong Qian, Yuanming Liao, Tao Bai

Patent number: 9019952Abstract: Embodiments of the present invention provide a method and an apparatus for forwarding multicast traffic. The method includes: receiving a third multicast join message; in response to the third multicast join message, sending a first multicast join message to a first upstream router, and establishing an active path; in response to the third multicast join message, sending a second multicast join message to a second upstream router, and establishing a standby path; and sending multicast traffic to the multicast receiver through the active path, where the standby path does not forward the multicast traffic. In the foregoing embodiments, the standby path that does not forward the multicast traffic is established beforehand, so that when a fault occurs in the active path, the standby path established beforehand can be used to forward the multicast traffic.Type: GrantFiled: January 7, 2013Date of Patent: April 28, 2015Assignee: Huawei Technologies Co., Ltd.Inventors: Tao Bai, Yunfu Yu, Gang Chen, Shuxue Fan, Hui Liu

Publication number: 20130279324Abstract: The embodiments of the present invention provide a tunnel fault detection method and a traffic engineering (TE) node. The method includes: receiving, by a traffic engineering TE node, a link fault report packet; determining, by the node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the node, whether one or more tunnels which use the node as an ingress node and pass through the faulty link exist; and identifying the tunnels as faulty tunnels if the one or more tunnels which use the node as the ingress node and pass through the faulty link exist. In the embodiments of the present invention, the TE node can detect all faulty tunnels at a time, and it is not necessary to wait until the fault notification based on each tunnel is received and then the faulty tunnel is identified one by one.Type: ApplicationFiled: June 24, 2013Publication date: October 24, 2013Applicant: Huawei Technologies Co., Ltd.Inventors: Fei Chen, Tao Bai, Lei Chen
