# As the "bufferbloat" folks have recently re-discovered and/or more widely | |
# publicized, congestion avoidance algorithms (such as those found in TCP) do | |
# a great job of allowing network endpoints to negotiate transfer rates that | |
# maximize a link's bandwidth usage without unduly penalizing any particular | |
# stream. This allows bulk transfer streams to use the maximum available | |
# bandwidth without affecting the latency of non-bulk (e.g. interactive) | |
# streams. |
