“…OSPFv2 supports two types of authentication [4][5][6]: one is simple password authentication and the other is MD5 cryptographic authentication. The authentication type is configurable on a per-interface basis and the 2-byte authentication type field (AuthType) in the OSPFv2 packet header should be set accordingly.…”

Routing information release is a kind of promise from the router for network reachability. Illegal routing information may have disastrous effects on the normal work of the network. Open Shortest Path First (OSPF) protocol provides authentication methods to protect the authenticity and integrity of the routing traffic. This paper describes two authentication types of OSPFv2, analyzes the realization mechanism and packet header format of each authentication respectively. Based on GNS3, a typical network topology was designed, and with the aid of it we carried out functional verification and security analysis. The simulation can provide a reference for building an OSPF network. Experimental results show that the configuration of OSPFv2 routing authentication can effectively prevent the router from receiving unauthorized or malicious routing updates, thereby improving network safety.

In this paper, a systematic robust control design and analysis for a single axis precise positioner is presented. The effects of uncertainties on closed-loop stability and performance are considered in the H ∞ robust controllers design. v-gap metric is utilized to validate the intelligently estimated uncertainty. The robust controllers are formulated within the framework of the standard H ∞ mixed sensitivity optimization problem. Furthermore, a specially designed integral-H ∞ and two-degree-of-freedom 2 DOF H ∞ controllers are developed to provide improved robust performance and resolution properties. It is shown that the proposed design schemes are very effective for robust control and precise tracking performance of the servo positioning system.

“…A TMSOTf–mediated glycosylation of 2 and 3 afforded the orthogonally protected disaccharide 28 exclusively as its α-anomer ( J C1–H1 = 172.0 Hz). 15 26 The stereoselectivity of the glycosylation reaction was attributed to neighboring-group participation by the 2- O -acetyl group of glycosyl donor 2 . Next, oxidative removal of the Nap ether with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) provided the glycosyl acceptor 29 , 10 which was coupled with the readily available glucosyl donor 4 27 by using a relatively large quantity of TMSOTf (0.5 equiv) as the promoter 28 to smoothly generate the desired trisaccharide 5 in a yield of 55% over the two steps.…”

Lipopolysaccharide (LPS) is a major virulence determinant in Gram-negative bacteria and responsible for many pathophysiological processes during bacterial infections. However, the accessibility of LPS-associated oligosaccharides for infectious mechanism study and vaccine development remains challenging. Herein, we report an efficiently stereocontrolled approach for synthesis of a common inner core trisaccharide containing difficult-to-access rare higher-carbon sugars heptose (Hep) and 3-deoxy-α-D-manno-oct-2-ulosonic acid (Kdo). Key features include comprehensive elaboration of practical synthesis of versatile Hep and Kdo building blocks and stereoselective assembly of an inner core trisaccharide from multiple pathogenic bacteria.
