去年不景气连带影响竹科人结交异性朋友、甚至结婚意愿,参加未婚联谊活动人数锐减
2-4成。今年景气好转,各单位举办的未婚联谊活动报名情形相当热络,不仅园区志工队

合法。注意不要写在合同里,也就是不要让银行看到(有的银行度 对自住房RENT BACK

品红酒,基本上记住五个S
see/swirling/smell/sip/swallow
see就是看红酒的颜色,属于品酒高人zhuangbility,不推荐
swirling就是前面说过的hold住支撑脚旋转,作用前面说过了,让空气和红酒充分混合,让香气散发出来
smell就是闻了,swirling完了之后赶紧闻,把鼻头凑到杯子里面闻,好的红酒闻起来绝对令人陶醉,此步骤绝不是装B。书上推荐说像狗一样sniff,似乎有些不雅
sip就是抿一小口,在舌头里面咣当两下,然后吞下去,我个人喜欢用鼻子把酒气喷出来,享受那个微醉的味道,跟抽烟一样
swallow就是一口干了
我认为中间三个步骤非常重要,有研究的没研究的都会有自己的感受。你拿瓶长城干红和napa valley的cabernet, 差别大了去了。
swallow反而是least pleasant的步骤。
见过国内大多数喝红酒的人只有swallow,而且是用塑料杯,喝的是长城干红(没办法,没得选),这么喝确实是相当之无聊的一件事情。

发信站: BBS 未名空间站 (Sat Nov 24 11:35:00 2012, 美东)
经常有人问电话卡的事情,我一直都在用skype,完全可以替代掉电话卡。
给大家科普一下:
skype推出两个新的功能(推出来也大概有1年了):
1. 可以给你一个接入号,打入以后就跟电话卡(免密码)使用
拨打接入号,会提示,按2后拨打对方号码,例如861013112345678,就可以了。
2. 你常用的号码给你绑定成本地号码(例如把你要打的中国号码给你绑定一个美国号
码),以后打这个本地号码(美国号码)就自动转到中国号码上去
这两个方式都可以直接用你的手机使用(不需要wifi),特别是2,可以把常用号码直
接保存在手机自己的contacts里面。非常方便。例如,你可以把861013112345678在绑
定一下,skype会给你分配一个号码,例如是718-555-5555.以后你要拨打
861013112345678的时候,只要拨打718-5... 阅读全帖

NP的优点缺点都很明显,ASIC也是。
一个例子就是Cisco 7600的SIP-400和SIP-600,sip400就是NP based,feature上没得
挑,可是虽然每个端口在任何feature打开的情况下都号称line rate,但是端口密度怎
么也上不去。而sip600就不一样,有限的feature的情况下,端口密度很大。
你说的第二点,俺同意50%。backbone的bandwidth暂时来看,不是当前最严重的问题,
当前的热点的确都在edge上。但是backbone之所以可以这样,都是因为这些年MPLS有关
的技术不断成熟,加上硬件的突飞猛进,但是当流量一旦上去了,就会面临河edge很多
类似的情况,
end to end的qos/cos,将来一定会流行。目前的implementation已经很多乐。
其实你所说的differentiate incoming packets就是术语上说的classification,这个
相对容易点,比较难的是后续的处理,比如如何处理oversubscription,这个对line

对,10G以上产品目前主要还是asic,sip--600也是asic的,因此功能上比np based
sip-400差一些。原先intel的np 部门上次卖掉了,忘记卖给谁了,不过他家本来在当

嗯,SIP + fax? 扫地老太太掩面遁走.....

低声提醒对方
说:小心,你要在 Voice Gateway 配置一个 transcoder, 你的 SIP trunk 的

算了,还是全英文吧,太不好翻译了。
Traditional:
PSTN - PRI ports on voice gateways - CallManager,PBX,Asterisk...Each PRI

I am reading something on Avaya Aura too. Implementations detail might be
different, but still very similar on big pictures like SIP/MGCP/H.323,
gateways, call agent, SBC, Session Manager, virtualization etc.
How do you guys think of SIP trunking to verizon etc, even skype?
