发帖数: 17771 | 6 听君一席话胜读十年书啊，看来俺对mobile network multicast implementation理解
的确有偏差，俺看了你的帖子，又看了些MBMS和eMBMS的东西，甚至重新review了一遍
mobile network architecture的一些东西，终于发现俺为啥理解有偏差了。俺以前没
有认识到从eNodeB出来到SGW/PGW或者从NodeB出来到SGSN已经是在走GTP tunnel了，而
是认为这些Tunnle只是在SGSN, GGSN或者PDSN, HA或者SGW, PGW之间。一旦认识到这个
，你说的就好理解了，multicast replication的确是放在MOBILE GATEWAY上面。

I see Starent promoted Femto solution and guess Cisco has Starent Femto

How come Cisco has to reply on Siemens to sell its GGSN? Because Cisco doesn

能会有一点出入，比如有下传的包，在基站拥塞的情况下被基站丢弃了，这种大概还是
会被计入。不过这种情况应该很少见。也就是说应用层的重传都会计多次的。网络设备
不管应用层在干嘛，有一个字节，计一个字节。 |
