I am starting to deploy GigE as a WAN technology. One nice benefit is that the equipment (Cisco 6500/7600 class) has capabilities not usually found in routers (such as remote port mirroring). Coupled with VLAN ACL's, this can be quite useful for ad-hoc remote diagnostics. One particularly interesting adaptation is sFlow (RFC 3176), currently only implemented by Foundry (I don't know of any other vendors planning to implement sFlow). sFlow is usually pitched against Netflow, I see it more as a diagnostic tool. It works quite like port mirroring, but also allows sampling and only sends header information to the collection server. Pete.
