Routing Algorithms: Shortest Path, Widest Path, and Spanning TreeWe also discuss spanning tree algorithms that are applicable in multicast routing.Deep MedhiKarthik RamasamyNetwork Routing (Second edition)
In this chapter, we first describe two classes of routing algorithms: shortest path routing and widest path routing. They appear in network routing in many ways and have played critical roles in the development of routing protocols. For example, shortest path routing is used in IP networks is ...
最短路 最短路径问题(Shortest Path)是图论中最经典的问题之一,该问题可以简单描述为找到一个图或网络中两点之间的最短路径。求最短路的常见算法有Dijsktra算法、Floyd算法、A*算法等,每个算法都有各自的特性,针对不同的应用场景,我们需要选择合适的算法以提高效率。Dijsktra算法是最早的求最短路的算法之一,其主要思想...
As the package name suggest, cppRouting is initially aimed to provide efficient algorithms for finding shortest paths. Algorithms Path algorithms proposed by the package are : 1 uni-directional Dijkstra algorithm, 2 bi-directional Dijkstra algorithm, 3 uni-directional A* algorithm 4 New bi-directiona...
Delay and packet loss probability performance of the MLSR and shortest path routing algorithms. Because the performance of MLSR has the same performance as the shortest path algorithm, consequently, both curves are overlapped. Full size image
The steady-state response of link-state and loop-free distance-vector routing algorithms to multiple changes in the costs of links is investigated. A quantitative comparison of an ideal link-state algorithm similar to the one used in the open shortest path first (OSPF) and in the OSI intradom...
Based on the thorough analysis of the network communication of the Network-on-Chip(NoC) and study of the shortest path algorithms, a directed Ford-Fulkerson algorithm is proposed in this paper. 文章通过对NoC网络通讯的分析,以及对现有最短路径算法的研究,提出了一种定向Ford-Fulker-son算法,实现了No...

OSPF(Open Shortest Path First)是一个内部网关协议(Interior Gateway Protocol,IGP),用于在单一自治系统(Autonomous System,AS)内决策路由。与RIP相对,OSPF是链路状态路由协议,而RIP是距离矢量路由协议。 链路是路由器接口的另一种说法,因此OSPF也称为接口状态路由协议。OSPF通过在路由器之间通告网络接口的状态来建立链...
