Question (fwd)

[Eric Henriksen]

>VPN means alot of different things to different people.  It's good that
>you have defined your terms clearly.  Within the IPSec VPN recomendations,
>what you are referring to are ESP Tunnels.  You could also use SSH,
>or PPTP, or L2TP encapsulating protocols combined with decent encryption
>to achieve this.  With this, AT&T's VPNS does NOT qualify as a VPN, since
>they are merely providing access lists in edge routers that the customer
has
>no
>management control over.  Many other carriers/ISPs are not providing
>integrated
>VPNs at all, but rather are partnering with vendors like ourselves to
create
>the solution (these include Cox, @Home, TGC/Cerfnet, etc).  Also, while QoS
>is an essential requirement of corporate network services, it is not
>presently
>available across the Internet, only on the access links via various queue
>mgmt
>schemes.  You may want to refer to one of the key players in bringing QoS
to
>the network layer via MPLS: http://www.ennovatenetworks.com/mpls/index.htm
>This will, however take some amount of time and cooperation by not just the
>vendors, but also the backbone Internet service providers to achieve this
>end-end
>with any reasonable coverage.
>
>Finally, it is the cost argument presented by the Internet that is offering
>IP VPNs
>the leverage and momentum they are enjoying over such connections over
>other more expensive backbones.  Anyone who can add QoS and security to
>the public Internet will be justly rewarded.

>>Thanks for responding Ryan; let me clarify more...
>>
>>1. I do agree and believe that VPNs can be implemented on top of any
>>network... and, i agree with yr def of seeing some tunneling and
encryption
>>in FR before calling them VPNs !
>>
>>2. I was reading a paper from Sprint; it says they offer Data VPNs that
can
>>be on top of FRs, IP and ATMs. I hope their def of VPNs is same as ours.
>>(i.e. use of tunneling and encryption)
>>
>>3. My understanding is that the growth of VPN-based services will be
>>largely as IP-based networks.  companies such as AT&T have their own IP
>>backbones and they can offer VPN data services on this backbone.  I
believe
>>many telcos and large ISPs will use Internet or their own IP-backbones to
>>offer VPN-based services, since, incorporating VPN technology basically
>>means tunneling, encryption, QoS, etc. Is this correct ?
>>
>>Also, even if some companies say that VPNs can be deployed on top of any
>>network (such as ATM, FR, etc.), is it not correct that IP-VPN based
>>services will have bulk of the market ?
>>
>>Any comments ?
