Abstract. As Virtual Leased Line (VLL) type point-to-point connections over Internet are now possible with the Expedited Forwarding (EF) Per Hop Behavior (PHB), Internet Service Providers are looking for ways to sell bandwidth services to prospective corporate customers with the so called Bandwidth Brokers (BB). Based on this approach most of the recent implementations consider providing such services only in a single provider domain. However, many of the ultimate customers might actually want to extend VLLs up to the periphery of other providers. In this paper, we describe the implementation of a BB that uses simple signaling mechanism to communicate with other cooperative Brokers to enable customers to dynamically create VLLs over multiple Diffserv domains.
