简单讲解 图的定义时 我们规定一个连通图的生成树是一个极小连通子图 含有N个顶点N-1个边 我们把图中带权的边最小代价生成的树成为最小生成树。 普里姆(Prim)算法prim算法适合稠密图,其时间复杂度为O(n^2),其时间复杂度与边得数目无关以顶点找顶点 考虑权值 存储方式为邻接矩阵 基本思想:假设G=(V,E)是...
解析:Explanation:STP’s main task is to stop network loops from occurring on your Layer 2 network (bridges or switches). It vigilantly monitors the network to find all links, making sure that no loops occur by shutting down any redundant ones. STP uses the spanning-tree algorithm (STA) to...

In the world of discrete math, these trees which connect the people (nodes or vertices) with a minimum number of calls (edges) is called a spanning tree. Strategies One through Four represent spanning trees. They connect all the people without creating a loop. Strategy Five contacts all the...
解析:Explanation:STP is used in LANs with redundant paths or routes to prevent loops in a layer 2 switched or bridged LAN.Incorrect Answers:A, B: The primary purpose of STP is to prevent loops, not for monitoring or management of switches or VLANs.D. VLANs are used to segment a LAN...
What is the reason for running spanning-tree in a Cisco Single-Site Secure Network Foundation Solution?() A. To protect the network in case someone inadvertently creates a physical loop in it B. To ensure that if a ...
5. Minimum Spanning Tree (MST) A Minimum Spanning Tree (MST) is a subset of edges of a connected, undirected graph that connects all vertices with the minimum possible total edge weight. Finding a graph’s MST is essential in various applications, such as network design, clustering, and res...
What is Spanning Tree Protocol In a networking infrastructure, a loop occurs when network packets continuously circulate among two or more network devices without reaching their intended destination. This situation arises due to redundant or multiple paths between network devices, causing packets to trave...
RSTP, an enhancement to STP, allows for rapid network topology convergence. However, both RSTP and STP have a defect, that is, all the VLANs on the same LAN share the same spanning tree. As a result, redundant links cannot be blocked byVLAN, and packets of all VLANs are forwarded alon...
