如今,各领域都需要尽可能高的网络可用性和尽可能小的数据丢失概率。因此,在网络设计过程中需要提供冗余,但相应地,也会需要更高的管理和运营成本。冗余协议有助于解决这个问题。第一跳冗余协议群(FHRP)可减少网络通信中从源到目的地的数据丢失。第一跳冗余协议群包括三个协议:热备用路由器协议(HSRP),虚拟路由器冗余协议(VRRP)和网关负载平衡协议(GLBP)。每个协议都有自己的目的,各有利弊。FHRP旨在减少流量损失。这些协议通过建立关联,从而成功地将流量从源传输到目标。在发生故障的情况下,将自动启动备用服务器继续发送流量。HSRP协议和GLBP协议是Cisco专有的,而VRRP协议是电气和电子工程师协会(IEEE)标准。本文通过多种仿真进行了协议之间的比较,以确定哪种协议在哪种情况下最佳。如果由于某些技术问题导致网络中的一个路由器中断,协议仍能够传输流量。此外,我们通过基于md.算法对上述协议进行了验证。通过使用不同的路由协议(如FHRP)包含md.5认证来模拟网络,完成md.5认证的分析。本文仿真基于GNS3平台,重点是实现在不影响网络有效性的情况下进行加密、高效、可靠的信息交换。

Journal of Coastal Life Medicine 2017年第8期5卷 360-364页

Objective: To evaluate the possible phytochemical constituents, antibacterial and anthelmintic activity of Coix lacryma-jobi L. (Job's tears) using the chloroform leaves and seed extracts. Methods: The test for antibacterial activity and minimum inhibitory concentration was conducted by the disc diffusion and two-fold dilution method, respectively. In anthelmintic activity test, using Pheretima posthuma model, vermifuge and vermicidal activity were determined by using the chloroform extract at various concentrations. Results: The preliminary phytochemical screening of chloroform extracts of Job's tears leaves indicated the presence of alkaloid, carbohydrate, saponin, glycosides, flavonoids, phenols, tannins and steroids whereas the seeds extract contained glycosides, flavonoids, phenols and steroids, which revealed highest antimicrobial activity against Bacillus cereus and Klebsiella pneumoniae. The lowest minimum inhibitory concentration (12.5–50 mg/mL) was observed against all selected bacteria. On the other hand, it has been observed that chloroform leaves extracts showed shortest time of paralysis (P = 8.17 min) and death (D = 18.23 min) at 100 mg/mL concentration, in comparison with seed extracts (P = 36.83 min and D = 62.33 min) at 100 mg/mL concentration and albendazole (10 mg/mL) used as reference drug (P = 20.17 min and D = 43.67 min), which indicated the plant possessed mild anthelmintic activity. Conclusions: The chloroform extracts (leaves and seeds) showed efficacy for both bacterial infections and parasitic diseases, which ensure the traditional uses of Coix lacryma-jobi L.

Residual Spray for the Control of <i>Aedes</i>Vectors in Dengue Outbreak Residential Areas

The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed tha
