发帖数: 231 | 2 Zher的关于tcp throughput问题面试经常考，以下几点答上了基本可以搞定工作：
layer1/layer2
1.整个path的MTU 能大尽量大。
2.网卡内的descriptor能设大尽量设大一些。
还有这些端口都有queue buffer,能大尽量大些。
有些网卡有tcp off-loader，不错，不过得根据应用而定。
3. 主机的总线得够大，不能告诉我说总线还是PCI 你要求用10G的速度啥的。
layer3以上：
4.tcp stack buffer 这个基本上可以根据BDP (bandwidth Delay Product)也是能大则
大（不是线性的增长，需要tunning), sliding window options 等等最新的linux/
window kernel 都有相应设定了，根据应用可以调节。
5.应用层/os socket的buffer.
整合：
6.最好用opnet 或者ns 先模拟一下，根据模拟的模型再测试调节。
最近做了个tcp 应用优化的项目，瓶颈基本上在storage. |

发帖数: 60932 | 13 Just a heads up, I have a Sony BDP-S270 Blu Ray player and just now had a
message to update my firmware so I did and now have Hulu Plus enabled.
Don't know if this is something that has been going on but the Hulu app
directed me to visit this site: Link:

I set it all up via the instructions on the Sony site and now my Hulu
account states the following:

发帖数: 60932 | 24 I updated the firmware in the Blu ray player from Sony Deals recently.. I
noticed that YUPP TV is available under the Video Apps section.
Opening the app, there is a section for Free Indian Channels.. which
includes many NDTV channels and few music channels in Malayalam, Telugu....
Confirmed in BDP-S580 blu-ray player
You can even subscribe to Yupp TV channels package and get Indian television
in Telugu, Tamil, Malayalam, Punjabi and Hindi...
Enjoy...
