Shortest Path Bridging (SPB) delivers traffic on the shortest path available and enables network virtualization in carrier grade networks and data centres.
802.1aq SPB is an IEEE networking standard with a primary focus on addressing STP challenges. However, SPB is more than just an STP evolution and unlike MPLS, which requires a “stack” of protocols (for example: LDP, OSPF, MP-BGP, among others), SPB relies on a single protocol to provide this functionality: IS-IS (Intermediate System to Intermediate System).
Alcatel-Lucent Enterprise Intelligent Fabric (iFab) provides further simplification by automating network node provisioning, client device attachment, and dynamic service instantiation. With this simplicity and automation, an ALE-powered SPB solution offers high-end services for a lower TCO.
