Paul, I would think that a laugh from enterprise datacenter operators is definitely not a reason not to innovate or evolve the technology; and more importantly, should not be a reason why certain protocol is not chosen as an effective solution. Unless there is a fundamental technical issue with any protocol, that given protocol should be considered a viable option.
Now, in terms of protocols at hand, ie BGP and MPLS, - yes there was a time many years ago, when IGP was sufficient to run the network, but as soon as that network grew into N x networks = internetwork, we all moved to BGP as the former was not suitable - and guess what - operators started reading RFC 1771 and 2547. Similarly, there was a time when we all run Spanning-tree and IGPs in data centers. But as we evolve DCs into complex networks of networks with scale requirements of millions of VMs, as charter states, we should reuse what's available and innovate when needed, but certainly not based on the premise of someone's comfort level, but actual technical requirement not addressable with existing tools. Protocols will evolve and operators will read; and this is just a beginning. Simplicity is a relative term. --- Senad On Thu, Apr 19, 2012 at 4:41 PM, Paul Unbehagen <[email protected]> wrote: > I usually hear a laugh from enterprise datacenter operators when BGP and > MPLS are mentioned as a option inside the DC. > > It comes down to the point of view that BGP and MPLS are too combersome to > be worth the time and effort for their environment when there are simpler > ways to solve the problems they've had and need just as simple ways to > solve the new generation of problems. > > -- > Paul Unbehagen > Director, PLM - Avaya Networking > Office: 303-538-1219 > Email: [email protected] > > Sent from my iPhone > > On Apr 19, 2012, at 11:28 AM, AshwoodsmithPeter < > [email protected]> wrote: > > > > >> I am very much concerned about this.
