Two high-profile provisions twisting their way through the IETF agree to improve data center switching and service donor routing, but advances from Cisco and Juniper Networks raise questions about how much the goggles are even needed.
For switching, the IETF is functioning on Transparent Interconnection of Lots of Links (TRILL), which is anticipated to conquer limitations of the Spanning Tree protocol in scale and topology reconvergence. For routing, the IETF is investigating the Locator/ID Separation Protocol (LISP), which is intended to improve addressing and load balancing for enterprises working with multiple ISPs.
While these may appear like solutions to long tardy networking problems, they may also be surplus with capabilities already or soon to be on the market. In the case of TRILL, Ethernet switch market leader Cisco will quickly be shipping Fabric Path for its Nexus 7000 switch that accomplishes the same tasks TRILL is projected to address though providing many more capabilities.
