发帖数: 292 | 4 我是怀念黑莓的键盘，而且我觉得Q10黑色边框比9900和将来要出的classic都要低调好
看，所以买来准备收藏。
这两天完成一次100%到5%的循环，用黑莓自带的软件查看了一下，用掉的这95%的电量
里面，System加上PIM service就用掉了50%，standby好像是10%几……所以耗电的原因
就是系统没优化好…… |

发帖数: 806 | 6 the good thing of 5gt is that it uses same code base as large box, same UI
1. surely it supports QoS/Traffic Shaping
2. supports multicast routing protocol (PIM), haven't checked ospf/rip, may
require advanced license
3. supports URL Filtering/AntiVirus
4. It does support IPSec/L2TP (not sure about pptp, maybe a bad choice for OP)
5. Deep packet inspection (supports SIP NAT, no need for UPnP)
6. Route based or policy based NATting
7. many others

发帖数: 66 | 8 224.0.0.5 is for allospf router, 224.0.0.6 is used for DR router in multi-
access network only. Although they are multicast groups, an OSPF router does
not send out IGMP joins for the groups, when OSPF is enabled on a router's
interface, this interface will be programed to send/receive packets destined
to those IP addresses. Since all happens across one directly connected link
, there is no need to build multicast tree, igmp join/query and pim process
are unnecessary. |

发帖数: 1055 | 9 Assuming we are talking about IGMPv1/v2 with PIM SM ...
Where did you get the idea that (*,G) will be pruned when traffic switches
from shared tree to source tree? (*,G), as its name implies, includes all
sources for group G, (*,G) will be pruned on shared tree routers ONLY when
last receiver from last hop router leaves the group, which is not the case
in your question.
So back to your question, when new source comes in, traffic will flow
through shared tree from RP to receiver normally, which h |

发帖数: 3271 | 12 Please ask Eric rosen, why virtual router is beat by RFC 2547 back to 10
years ago, control plane signaling aggregation for sure better than
virtualizaing for each customer instance. if multicast bgp can just use PIM
without BGP, can we consider further to remove BGP for unicast as well? i.e
run ospf to cpe, extend ospf to cross the core. |

发帖数: 17771 | 18 有肯定还是有的，不管几G，从cell site总得出来吧，厚厚。而且这段是所有运营成本
里占最大头的一块儿，怎么可能没有了。4G里照样需要aggregation。
这段backhual可以是layer 2（比如纯carrier ethernet），也可以是layer 3（纯IP网
），也有layver 3 over carrier ethernet，最后这个可能在美国更加普遍些，因为不
管哪家的coverage都没有那么大，很多都要租用其他家的carrier ethernet。
不管哪种，都可以有multicast需求，纯layer 2（其实也是一张layer 3/mpls网，只不
过上面提供EVC而已）有IGMP Snooping的需求，layer3的就不用说了，现在新的cell
site router一个重要feature就是要支持PIM，不过大部分只需要static RP就可以，没
有auto-RP or BSR的需求。毕竟现在有刚性需求的BACKHUAL还很少很少，不代表1、2年
之后需求不强劲。而且现在好多项目都被IPV6给占了。
对于基于PON的backhaul，不是很熟悉... 阅读全帖 |

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

每个网里按一个rp, 现在源和终点各在一边。允许SPTswitchover.
问题是，有些组的终点到源的SPT 是错的，此时，东西传不过去。
有的组，好像也能找到正确的SPT,
当源和终点在一边的情况下，似乎总不出问题。 |

发帖数: 1953 | 24 Are the sender and receivers of multicast traffic are
all within the same home network? If that's the case,
you don't even need a PIM(or some multicast routing
protocols like that)-capable router to connect all
devices up. Just hook all boxes up with a switch if you
don't have too many devices. Linux kernel2.4/2.6 has
built-in IGMP support. |

L2VPN and MPLS L3VPN, MPLS L3VPN is standardized in well known RFC2547,
payload is IP, MPLS L2VPN is a general term for (Cisco)AToM, EoMPLS and
VPLS, payload is FR/HDLC but more commonly Ethernet/Ethernet VLAN.
ISPs need to run IGP in their own internal network, because MPLS LSPs are
typically among iBGP loopbacks, iBGP has to be on top of TCP/IP, of course
you can have MPLS LSPs that are purely used to transport IP tra... 阅读全帖 |
