What is the 100GE ATCA switch that we need today?

Though chassis and backplane vendors have announced support for 100Gb/s over the backplane (100GE), it does not appear that this capability will be required in the immediate future. In fact, it might be overkill for the time being. Just recently, Intel announced the general availability of the Fortville, a 40GE (and not nearly a 100GE) NIC, while other chipset vendors are not even able to deliver Fortville’s level of throughput. Furthermore, even if NICs are able to offer full 40GE backplane ports, this does not assure us that applications can…

Can an ATCA switch be used for SDN?

Software-Defined Networking’s vision is to separate the network’s control plane from the data plane and to encourage two layers of equipment: (1) simple, “bare metal” switches throughout the network running OpenFlow/NETCONF and (2) centralized SDN controllers to manage the data path. The controllers constitute the smart engines that carry a virtually unlimited quantity of Ethernet links to connect the simple switches running along the data path. The SDN controllers participate in a network that supports OpenFlow and NETCONF capabilities. They also reserve room for high-level applications such as load balancers and…
