CSPF，全称为 "Constrained Shortest Path First"，其中文直译即为"先约束最短路径"。这个术语主要应用于计算机科学领域，特别是在网络路由和路径规划中。该缩写词的流行度达到了30,819，表明它在专业领域有一定的使用频率。CSPF的缩写源自英文单词，表示在面临特定限制或约束时，寻找最短路径的一种算法。...
The first request indicates the ingress node, an egress node, a network constraint, and a scheduled time interval having a predetermined start time and a predetermined end time for the temporal LSP to carry traffic. The ingress node further includes a processor coupled to the receiver and ...
In recent approaches, the constrained shortest path first (CSPF) algorithm has been widely used in the PCE based implementations. The child PCEs were programmed to compute the paths based on either the Constrained Shortest Path First (CSPF) algorithm or the Adaptive Least Congested algorithm (ALCA...
Soft Constrained Shortest-Path First TunnelingSoft Constrained Shortest-Path First TunnelingIn one embodiment, a method includes obtaining a request to route traffic from a source to a destination in a network, where the request is associated with a setup bandwidth criterion. The method includes: ide...
What is Constrained Shortest Path First (CSPF) Chapter 14 The path computed using CSPF is a shortest path meeting a set of constraints. Thus it runs the shortest path algorithm after discarding those links that do not meet a given set of constraints. Examples for constraints: minimum bandwidth...

First, the theoretic framework is developed, and a number of methods are proposed and analyzed. Second, some of the methods are tested computationally. In the third part, generalizations of the VRPTW are considered.In the theoretic part of the dissertation, we outline the relationship between the...
This paper presents a particle swarm optimization (PSO) algorithm for solving the delay constrained least cost (DCLC) path problem, i.e., shortest path problem (SPP) with a delay constraint on the total "cost" of the optimal path. The proposed algorithm uses the principle of Lagrange relaxati...
