Abstract:
1. A computer implemented method for providing virtual local area network capacity requirement estimation, the method comprising: receiving at a computing system an identification of virtual local area network access ports, virtual local area network switches and virtual local area network trunks in a virtual local area network; determining at the computing system a target trunk and a target switch corresponding to a target access port, wherein the target trunk corresponds to one of the virtual local area network trunks and the target switch corresponds to one of the virtual local area network switches; calculating at the computing system a bandwidth contribution of the target access port to the virtual local area network, wherein calculating the bandwidth contribution of the target access port to the virtual local area network includes: splitting the virtual local area network into two portions based on location of the virtual local area network switches relative to the target trunk, wherein one portion includes the target access port and is an access port side and the other portion is a non-access port side; calculating a current access port side bandwidth requirement responsive to the virtual local area network; calculating a potential access port side bandwidth requirement responsive to the virtual local area network and to the target access port; calculating a current non-access port side bandwidth requirement responsive to the virtual local area network; and determining the bandwidth contribution of the target access sort by subtracting a minimum of the current access port side bandwidth requirement compared to the current non-access port side bandwidth requirement from the minimum of the potential access port side bandwidth requirement compared to the current non-access port side bandwidth requirement.
