第11题:
DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings.
DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber.
In DPT/RPR rings, data packets can be sent in one direction (downstream) and the corresponding control packets in the opposite direction (upstream),thus using both fibres concurrently to maximise bandwidth.
DPT/RPR can be deployed in the Core of the SP networks where point-to-point POS links are used tomake best use of the Bandwidth.

over leased lines, use the multilink ppp command to reduce latency and jitter, and to create Distributed Link Fragmentation and interleaving
use the service-policy command to attach a traffic flow to an interface on the router
use the ip rsvp bandwidth command to set a strict upper limit on the bandwidth NBAR uses, and to guarantee admission of any flows
use the policy-map command to define one or more QoS policies (such as shaping, policing, and so on) to apply to traffic defined by a class map
use the random-detect dscp command to modify the default minimum and maximum thresholds for the DSCP value
use the class-map command to define one or more traffic classes by specifying the criteria by which traffic is classified

Receiving broadcast traffic
Negotiating spanning tree with upstream switches
Learning MAC addresses from upstream switches
第23题:
Downstream RS error correction effectiveness is reduced
The downstream line rate and throughput remains unchanged, but FEC efficiency is reduced
The upstream DSL bandwidth is reduced, since less carriers become available for upstream traffic
The downstream DSL bandwidth is increased
