Cited from NSN people blog, new iPhone OS, iOS 4.2, tests by Nokia Siemens Networks have shown that iPhone iOs 4.2 support a technology called Network Controlled Fast Dormancy, which have already introduced into NSN networks. This will cut smartphone signalling down to size.  Basically, the technology makes the network and the handset work together to create the best conditions for smartphones to work quickly, yet have a long battery life and minimize network congestion.

Today internet is rather different with few years ago.  Few years ago, internet is very dependent to Tier 1 ISP.  If you have many Tier 1 IP Transit, you can have better internet access, because more route can you reach with best path. 

Many IP transit now have their own CDN, but it is likely not a free service.  Traditional CDN, like Akamai, are open for ISP to partner with them.

Deleting Statement from JunOS Configuration
Here example for deleting a statement from JunOS Configuration.  I use BGP configuration for example.

Cisco router can be used as VPN server, using L2TP and IPSec, for client from internet accesing private network.

This post will describe how to create VPN Client using L2TP and IPSec on Windows 7.

This post will describe how to create VPN Client using PPTP on Windows 7.

Cisco router can be used as VPN server, using PPTP, for client from internet accesing private network.

As using route reflector is a way simplifying and scaling iBGP configuration, it is recommended to use if you have many routers in your AS.

IBGP require all BGP systems within the AS are a fully meshed, so that any external routing information is redistributed among all routers within the AS.
