GMPLS-Based Optical Slot Switching Access-Distribution Network With a 10 ns High-Speed PLZT Optical Switch

This paper designs and implements an optical slot switching network for bulk content transfer. To realize the slot switching network, the paper employs the Generalized Multiprotocol Label Switching (GMPLS) extension protocol to reserve and release slots dynamically according to the application. The paper uses optical switches as relay points in the slot switching network, and one employs a 10 ns high-speed Pb,LaZr,TiO3 (PLZT) optical switch. The paper extends the resource ReSerVation Protocol - Traffic Engineering (RSVP-TE) and realizes optical slot reservation. In the slot reservation, the proposed scheme allocates a slot in a frame for clients in order to guarantee the minimum bandwidth. The scheme considers the accelerated and tentative slot reservation. In the slot switching network, one uses the PLZT optical switch.
