In an edge computing environment, in order to provide highly accessible services and computing resources to nearby users, edge servers are usually deployed on base stations and other types of equipment. However, due to the limited storage space of edge servers, it is very difficult to manage services with a failure. Therefore, the rapid restoration of services in the edge computing environment will become an important means to ensure the resilience of the system. Among them, service replacement with similarities within the edge server is one of the effective technologies to ensure system resilience. In this paper, we regard the discovery and scheduling problem of replaceable services replacement as the discovery and scheduling component, and develop an approach based on replaceable service form the app vendor’s perspective for solving the none replaceable services environment. We have evaluated our approach in a real experimental environment. The results show that in the case of large mirroring, the DAS approach can effectively reduce the recovery time required by the system due to failure.

To compare the effects of oblique insertion at anatomical points and conventional acupuncture for sacroiliac joint injury.Eighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, oblique insertion therapy at anatomical points was used, and the 9 points of equal division (anatomical points) marked by palpating the anatomical symbol were treated as the insertion acupoints. In the control group, conventional acupuncture was applied, and perpendicular insertion was adopted at Huantiao (GB 30), Zhibian (BL 54) and Weizhong (BL 40), etc. In the two groups, the! treatment was given once a day and 5 times per week. Ten treatments were made into one course and two courses were required. The clinical effects, the changes of visual analogue scale (VAS) and Oswestry dysfunctional index. (ODI) before and after treatment were observed in the two groups.The total effective rate of the observation group was 90.0% (36/40), which was better than 72.5% (29/40) of the control group (P0.05). After treatment, the results of the VAS and ODI of the two groups were apparently declined (both P0.01), and those in the observation group were decreased more obviously (both P0.01).The effect of oblique inser-tion at anatomical points for sacroiliac joint injury is superior to that of conventional acupuncture, which can effectively relieve pain and improve the disfunction.
