SPEWS removal (SPEWS: S1970, 65.107.235.160/27)
by Michael L. Barrow 01 Oct '02

I believe that SPEWS has made an error by listing these 3 /24s (65.107.234.0 - 65.107.236.255, Chase Financial Funding (XO)) in its database as I my organization (using 65.107.235.160/27) has nothing to do with Chase Financial Funding. The fact that we're both connected to XO and are both in Laguna Hills, CA is merely a coincidence. It would be greatly appreciated if someone could correct this error.

RE: Economic Justification / Rationale for MPLS
by Matt Ryan 01 Oct '02

Whatever the relative technical merits of MPLS/BGP VPNs over other layer 3 VPNs (GRE, IPsec, L2TP etc) there are many service providers around the world selling these services. There is clearly a business need for them, and obviously customers how will buy them (well, we have managed to sell them anyway!), so there is an economic reason to deploy MPLS. Layer 2 based LAN extension services will only extend this market further and again uses MPLS as its base transport mechanism.
