    摘要： One embodiment pertains to a switching device which is configured to provide multicast traffic management in a layer 2 network without layer 3 devices A specific embodiment relates to a method of implementing IGMP multicasting in a layer 2 network. IGMP packets are snooped by multiple switches in the layer 2 network. IGMP query messages are generated by each of the multiple switches. IGMP join report messages are forwarded by each of the multiple switches to all ports on which a querier is present. Other embodiments are also disclosed.

    摘要： A process for preparation of ceramic objects which comprises: (a) applying a layer of a high-solids photocurable ceramic composition, to a substrate, the composition comprising: (1) at least 10 percent by volume of water; (2) at least 0.05 percent by weight of photocurable compounds which are soluble or dispersible in water; and (3) at least 45 volume percent dispersed ceramic particles; and (b) subjecting the composition to sufficient ultraviolet radiation to react the compounds or polymers sufficiently to form a layer of the photocurable compounds or polymers, which is water-insoluble and non-dispersible in water, having the ceramic particles dispersed therein.
