The present invention relates to a complex composed of cucurbituril and fullerene and a method for manufacturing the complex on a solid-phase. The optical phase modulation element includes a Plasmon waveguide having a clad made of a metal material having a complex dielectric constant having a negative real part in the used wavelength and a core formed by a dielectric metal material having a complex dielectric constant having a positive real part in the used wavelength. Disconnected anterior impact braces extend anteriorly to a medial region forming a gap therebetween. If the current switching load due to traffic from all of the LAN ports is equal to the maximum switching capacity of the router resource, however, those of the LAN ports that are attempting to utilize more than their fair share of the bandwidth availability or the switching capacity may be throttled back.
