Abstract:
A switching fabric which provides substantially jitterless and lossless transmission from a source switch to a destination switch in a network, comprising:at least one switch processor for determining, in response to at least one call request, if capacity exists in a link to establish a route from said source switch to said destination switch, said at least one switch processor blocking said call when no bandwidth is available;at least one buffer for holding data packets associated with said at least one call when bandwidth is available in said link, said at least one buffer coupled to said switch processor; andsaid at least one switch processor further operable to provision a required number of contiguous time slots in a specified frame when said bandwidth is available in said link, said processor further operable to route said data packets by counting said number of contiguous time slots provisioned to said data packets and cross-referencing said number of contiguous time slots to an output port and to switch said data packets in said given time frames.
