第6题
A、DiffServ requires RSVP to set up a path through the network to accommodate the requested QoS. B、Network traffic is identified by class， and the level of service is chosen for each class. C、The DiffServ model relies on a fairly simple mechanism to provide QoS over a wide range of equipment. D、RSVP enables the DiffServ model to provide end-to-end QoS. E、The DiffServ model is more scalable than the IntServ model. F、The flow-based approach of the DiffServ model is ideal for large scalable implementations such as the public Internet.
第7题
A、 A class can be identified as a single application， multiple applications with similar service needs， or be based on the source or destination IP addresses. B、 A drawback of the DiffServ model is that it does not provide backward compatibility with devices that can only use the ToS field. C、 DiffServ uses the DiffServ field in the MAC header to mark frames into behavior aggregates （BAs）. D、 The DiffServ field occupies the same eight bits of the MAC header that were previously used for the ToS field. E、 The first six high-order bits of the DiffServ field are used to identify the Resource Reservation Protocol （RSVP） value. F、 The primary goal of DiffServ is scalability.
