以winshark 和

假设我的snoop 结果 是 a.snoop,前文说的snoop.txt是我用
snoop -i a.snoop -x0 > snoop.txt 得到的. 但snoop.txt中可读的文本在最右列, 我
还得某种方
式把可读的文本取出来再search我要的字符串. 麻烦.
我现在想了一个别的办法:
snoop -i a.snoop -v > a1.txt, 这样我可以从a1.txt里得到packet headers 信悉了(而
我要找的字符串 就应在http header 里).如:

Guess it's not enough to just list reference, I should have copy/paste the
key points here.
The reason is IGMP Snooping, but only IGMP Snooping in very AGGRESSIVE mode,
which will also snoop on permanent group (i.e. 224.0.0.0/24). Most of IGMP
snoop apply to groups outside of that range, thus not causing problems for
OSPF and other routing protocols, such as EIGRP, RIPv2 and etc.
RRAS is only mentioned as one of multiple vicitims of this "aggressive" mode
of IGMP snooping from certain vendors.

据韩国《朝鲜日报》网站5月31日报道,以江南style在youtube上创造了20亿浏览记录的鸟叔,带着新歌《hang over》回来了。
31日,据YG娱乐公司透露,以美国东部时间为标准,鸟叔预定在6月8日晚7时播出的美国ABC脱口秀节目“吉米·基梅尔live:游戏之夜”中,与世界级hiphop音乐家Snoop Dogg一起出演“hang over”并亮相。
Hiphop歌曲“hang over”展现了鸟叔与“江南style“,“gentleman”完全不同的面貌,值得期待。
和鸟叔一起表演的Snoop Dogg的原名是小卡尔文 布罗德斯(Calvin Cordozar Broadus Jr.)。是美国hiphop界最有名的说唱歌手,曾作为电影演员在1992年参加了美国的hiphop歌手安德烈·罗米尔·扬(Dr. Dre)的专辑,开始了音乐活动。
直到2013年为止,Snoop Dogg发表了包括《转生》等10多张专辑在内的500多首歌曲,被评为“美国hiphop界教父”并积极开展活动。

大陆节目《中国有嘻哈》播出后引起热烈讨论,就算平时不懂嘻哈音乐的网友,也会加入讨论参赛选手的表现及花边新闻。陈冠希及欧阳靖(MC Jin)近日作为嘉宾出演大陆某直播节目,女主持人虽称自己平时有听嘻哈音乐,却把Snoop Dogg说成Snoopy Dog,让他瞬间暴怒。
陈冠希与欧阳靖在直播中与网友分享对嘻哈的看法,最刚开始欧阳靖对自己的规划侃侃而谈,女主持人话锋一转提及想知道陈冠希对于中文嘻哈的发展及氛围,此时他的表情严肃,反问“今天我们在聊Hip Hop,那你知道什么是Hip Hop吗”,对方表示“是种文化”,但他认为现在大陆的嘻哈风潮只是种娱乐,“我找不到真正Hip Hop的元素在里面”,甚至直接点名一些嘻哈的代表人物都被忽略了:“大支在哪?MC仁在哪?王波在哪?”

不觉得多夸张。
Each unit on the EIB can simultaneously send and receive 16B of data
every bus cycle. The maximum data bandwidth of the entire EIB is
limited by the maximum rate at which addresses are snooped across all
units in the system, which is one per bus cycle. Since each snooped
address request can potentially transfer up to 128B, the theoretical
peak data bandwidth on the EIB at 3.2 GHz is 128Bx1.6 GHz = 204.8 GB/s.

Doing a simple Google search on "igmp snooping" will give what you want, but
here we go, IGMP snooping is a L2 ethernet switch feature where switch can
intercept IGMP report/query messages exchanged between host and L3 router,
the switch then program it MAC forwarding table such that multicast traffic
is only forwarded to ports which have active receiver, without the feature,
multicast traffic will be broardcasted to all ports in the same VLAN. Of
course, all these have to be done in hardware.

igmp report/query doesn't have to be between hosts and L3 routers, a L2
switch can also send out igmp snooping querier and expect igmp join/report.
it was my understanding too that in the old time, ospf doesn't need to join
any mcast group. However, the fact is, on most high end or mid range switch,
igmp snooping is on by default for every VLAN, and not every switch vendor
seperates 224.0.0.x groups and treats them like broadcast. With this being
said, OSPF needs to do something in order to take

来自主题: EmergingNetworking版 - 今天的一个multicast session很失败
在mobile 里,handset/UE 的LAYER3 anchor 在 core network gateways, 例如 PDSN/
HA in 3GPP2, GGSN/PDN GW in UMTS and LTE 才是 mobile terminal 的IP 接入点。
所以基于目前3GPP, 3GPP2标准,真正做MULTICAST 功能aware 的在 UE/handset 和
mobile core gateway 上, 标准有 MBMS,BCMCS 等 。 至于L1,L2,L2.5
transport, 就算他是花样繁多的,乃至基于IP或甚至SCTP, HTTP tunneling 更高层
封装的,对MOBILE 而言是transparent transport 而已, 与这个topic 并不相关。何
况 UE 到核心网段还可以做加密,
至于 Cell site router enable PIM 我唯一能理解的是给Femto cell/HeNB 这样的
local breakout, 否则不太make sense. snooping 也许有用但不是MULTICAST 核... 阅读全帖
