What have been the routing implications in regards to internet traffic with SMW4 cable beign down? Regards, Shake Righa
Re: BGP and convergence time
Believe have narrowed down problem to layer 2. A ping to address 224.0.0.5 shows no reply.

Testing Internet Speeds and Capacity
Hi, how does one truly test internet speeds provided by your provider. Speed test sits give different results that one provided by the provider. Regards, Shake
Re: Testing Internet Speeds and Capacity
The tools such as iperf need some level of expertise to use. some end users lack this level of expertise. are there any tools simply for end users to use that can accomplish the same task?\ Regards, Shake Righa On Fri, Nov 20, 2009 at 6:56 PM, Jeff Shultz wrote: > shake righa wrote: > >> Hi, >> >> how does one truly test internet speeds provided by your provider. >> >> Speed test sits give different results that one provided by the provider. >> >> Regards, >> Shake >> >> > Nice ISP's will put speed test software on their backbone so you can test > the speed of your circuit to the backbone. > > Remember that the speed your provider quotes you is probably the full > throughput of the circuit.

Re: Testing Internet Speeds and Capacity
At the moment the market is competitive and clients are getting various different offers from different competitors.Thus you find them enquiring about speeds hence need to check on the speeds. onsite engineers too need to be able to test and provide accurate results.thus need for a tool that can provide accurate results.

IPv6 Newbie
I have several queries in regards to ipv6 different documentation state that clients be given /64 with ISP's beign given /48 from assigned global /32. Can one subnet to include /127 for point to point connections? Is there any newbie guide for ipv6 subnetting? Regards, Shake
