Vendor-Independent Bandwidth Broker Architecture for DiffServ Networks

A bandwidth broker (BB) is an automated resource manager in the Differentiated Services (DiffServ or DS) architecture. It manages Quality of Service (QoS) resource allocation requests within a single or successive DiffServ domains based on the available resources and on the service level agreements (SLAs) formerly negotiated between the customer and its service provider. If used for multi-domain resource management, BBs negotiate among each other on the behalf of the service initiator. Additionally, BBs also participate in transit domain communication by coordinating SLAs across domain boundaries.
