10月20日 IPTV方案的启发...IPTV -- 电信增收之新篇章
好处: 在DSLAM设备上实现宽带网业务与IPTV业务分离采用专用链路连接到SR上,绕过BRAS
13.如果业务扩展,考虑采用专有RPR环承载IPTV
8月16日 随笔(下雨,打不了网球了~)1.思科对电信说,不要建MPLS网了,用QoS吧. --电信赚钱也不容易呀...
2.思科说不要肓目做QoS,先得分析够了再做呀. --QoS, 原来IPFIX是基础...
3."Forwarding outages < 3m (不用看其它的了,就这一条就知道此网有多变态了...)
Packet Loss 0.05% (不在设备里,而是光纤传输中)
Packet Reordering 1%
RTT US 100ms (美国国内延迟)
RTT World 380ms (哥哥呀,岳阳光缆就有一万多公里呀)
Jitter 30ms (设备的缓存看来是不能少的)
BW/Delay Quota 2.4G/350ms
MTU 4470B (Fragmentation越少越好了)"
--摘自"Sprintlink网站"
大家不要报怨IP没有QoS了. --网络原来可以做得这么好的...感慨万千...
总结: 规划 --> 监控 --> 调整 --> 规划 == 完美的QoS
(鼓掌~ 噼里啪啦, 噼里啪啦~)
6月14日 Words... A night when I don't feel like working, even though there are so much work pending. Don't know what happened, but my head just went blank... Yeah, don't wanna work...
Spent some time online searching for nice songs to listen to, didn't find any, so fell back to listen to the oldies. I guess most of the time I feel like writing is when I feel negative and have to get the crap out of my chest.
Let's see what happened since I came to work in Ruijie. Well, most of it was to prepare for DI training, and the VISA surely got a lot of people edgy and exhuasted. And there is this Arthur guy from Taiwan, who was definitely polite, even though, at times, I bet the only thing he felt was also edge and disappointment. Well, that reminds me of something else about this guy-- He talks slow... Which I "think" I've been trying to imitate at times... Why? Can't really say... Maybe for some guy that just graduated, I feel like the need to talk less and think more. Or maybe I wanna be more calm and don't wanna be agitated by my own "talking" -- if you talk fast, you would know what I mean...
Anyway, the 3 months since I got here were busy. Besides DI, I get to monitor network testings in India from time to time. And I even went to Chengdu R&D Center to stimulate some field testings in India. Now let's see what I've learnt the most from the 3 months working in Ruijie???
Yeah, big question mark~ can't answer that... At least not yet...
Yesterday on my way out of the metro, I ran into a small stall besides a construction site selling original English novels. Gotta say I haven't touched those babies for a long time, yeah, since I got involved with this networking training program in college -- it was almost like I "quite" reading English novels. Anyway, I bought two books and kept the phone number of the street vendor -- it was Jack Welch's "Winning" and "A Beautiful Mind". The second book is about John Nash, the mathematical genius who came up with "Game Theory" and won a nobel prize in economics, and his life struggling with paranoid schizophrenia. On my way home, I kept thinking about my conversation with my sister the other day -- she told me about her idea of opening a language school in Hengyang. But she's in Germany, so we both know that's gonna take a while. What kept me occupied was the thought --"If I did go back home and open a language school with my sister, I would probably have all the time I need to READ." You know what? That just sounded so tempting in my head, and it sounds tempting even NOW~!
Yeah, in my heart I know, for the moment, I need more insights into the networking industry, the knowledge and skills to survive... Damn, I miss those years of reading back in college, those crazy years~ I even thought I should go to a graduate school and study English literature -- well, that did almost happen...
Kinda late now...
Nighty nite, friends.... 3月16日 流浪的蜘蛛~今天鼓起勇气重开博客。
挺不容易的,一只蜘蛛从长沙流浪到武汉,从武汉流浪到深圳,从深圳流浪到福州--看样子还是要继续流浪下去。其实不为别的,只为这只蜘蛛想要变成大蜘蛛。其实我从小就恐惧蜘蛛,想不到长大了却变成了蜘蛛。
对以后的工作真没什么头绪,想着要和一帮印度阿三周旋,看着他们摇头是点头,吃饭用手抓还得一定用右手,用钱还得想着人民币和卢比怎么换,不然花钱还找不着感觉,最郁闷的是,不知道上哪里去找肉吃...到时候跟这么一帮人用英语讲技术,心里一个字--汗。。。不过我老爹倒是蛮happy的,还兴高采列的要帮我办护照。真是人不在江湖,不知江湖的苦啊。不对,应该是人不做蜘蛛,不知道蜘蛛织网的难啊...手里面还有一本书,不知道这几天能看完不。
为什么女人喜欢逛街,男人不喜欢呢?就算是女人上街帮男人买东西,男人也会觉得前途无光呢?不知道百度“知道”里可不可以搜得到答案的。。。
以后要多写写技术方面的心路历程,也好天下蜘蛛大家共同进步,能为社会织更好的网啊。。。 10月26日 Breathe Again...Have you wondered how it feels when it's all over?
Wondered how it feels when you just have to start anew? Never knowing where you are going, when you face a brand new day. It used to be that way... I just wanna close my eyes and say,
I just wanna breathe again, Learn to face the joy and pain. Discover how to laugh a little, cry a little, live a little more. I just wanna face the day,
forget about the woes of yesterday, maybe if I hope a little, try a little more, I'll breathe again... Starting out again is never easy,
disappointments come and go, but life still moves on. With a bit of luck, it's a brand new start, it just might work my way, no need to walk away. Don't wanna live lives of replay. ......
---- Breathe Again First heard the song many years ago, I still remember the first night I was listening to it. Yes, vividly. There are just so many things in my head now, feeling just a little messed up.
A cigarette may help.
I'm not sad, actually I'm feeling kinda happy now, happy that my darling is with me.
For the whole time, I think I've been trying to be a little more positive and have a little more faith -- after it was lost. Sometimes I wonder why it's so easy to loss heart, to loss faith. Maybe it's just easy, but it doesn't really make things better. You say bad things about the world, but the world won't pity you and make things right for you. I know I tried to hide a lot, even now I still do that, but it's a lot less than before.
Things are difficult sometimes, but maybe we just need the "courage to live through the night, and see the break of dawn!"
Darling, I can't describe it. You are a very strong girl.
Your strength has had me feel some feelings, feelings of peace and happiness. I can feel it, feel you with me. Even though I feel tired out of working the whole day, my heart is quiet and powerful and full. The cigarette is almost finished. Why it makes me feel more hungry? ...
Kisses and hugs, darling. 10月16日 Where is it?Haven’t updated it for an awful long time – but suddenly sitting before the screen, I feel wordless and kinda paranoid.
Just lit a cigarette, yeah, does feel better now.
Lately it’s just been so easy to loss control – can’t exactly tell why.
Slowly I puff in and out the smoke, and try to put my mind in an easy place. Memories are flashing back and forth – I feel edgy and restless now.
Don’t know why I suddenly felt like writing, maybe it's just to keep myself from getting more "out-of-control".
Will you hold on to me I am feeling afraid
Will you hold on to me, We will never fail
I want to be so perfect you see I want to be so perfect…
Things will be fine... |
