Shortest Path Bridging (SPB; IEEE 802.1aq) vs TRILL/VCS

Hello all.

We are getting more and more in the discussions and competition at customers on how to setup a DC network and especially how to interconnect to DCs which have a big distance (>5 kilometer) in between.

Current Brocade VCS and Cisco FabricPath technologies could not be used to interconnect both DC networks over this long distance.

But other vendors step in with Shortest Path Bridging (SPB; IEEE 802.1aq) and tell the customers "forget TRILL or anthing like this, SPB is the future for DC and DC interconnect".

What do you think about this?

What are the Pros and Cons on Shortest Path Bridging (SPB; IEEE 802.1aq)?

Thank you very much for your input,

Karl

Hi all,

The following is a good overview on why both protocols will be with us moving forward.

Also a good read here

http://wikibon.org/wiki/v/Network_Fabrics,_L2_Multipath_and_L3

Notes - Please remember I do not work for Bocade

VDX will get L3 code at some point - no idea when

Brocade have at their technology day announced a product to do DC to DC connectivitiy.  Notreleased as yet.

Brocade have talked about distance ISL links before as well (and do now on the FC side)

Brocade also have made mention of VCS cloud ID's

Thanks

Michael.
