The CSPF calculates an optimum … Webbased shortest path first (CSPF) routing algorithm with multiple QoS metrics. This algorithm, called the multiple constraint-based shortest path first (M_CSPF) algorithm, provides an optimal route for setting up a label switched path (LSP) that meets bandwidth and end-to-end delay constraints. In order to maximize the LSP accommodation

Web10 12 b 25 24 6 C 13 20 9 An MPLS system uses RSVP with a CSPF algorithm to assign paths to demands. Each link has capacity 1Gbps (in each direction) and node s wants to reserve 400Mbps of capacity for each of the 9 destinations. Paths are reserved in alphabetical order (s za, s->b, ..., 5-> t). WebThis algorithm can be used to compute LSPs between two nodes of the network. In that sense, the use of this algorithm is quite similar to the use of CSPF algorithm.

Constrained Shortest Path First - Wikipedia

WebAbstract—Shortest path algorithms such as SPF and CSPF are widely used in online traffic engineering where connections need to be setup one at a time as connection requests arrive sequentially. We propose an ap-proach, called design-based routing (DBR), whereby optimized paths com-puted offline are used to guide online path setups. http://www.cs.utsa.edu/~korkmaz/citations/PapersCitingMe/MahiNetworks2003.pdf

http://docs.frrouting.org/projects/dev-guide/en/latest/cspf.html Constrained Shortest Path First (CSPF) is an extension of shortest path algorithms. The path computed using CSPF is a shortest path fulfilling a set of constraints. It simply means that it runs shortest path algorithm after pruning those links that violate a given set of constraints. A constraint could be minimum bandwidth required per link (also known as bandwidth guaranteed constraint), end-to-end delay, maximum number of links traversed, include/exclude nodes. CSPF is widely …
