Design and Implementation of Shortest Path Bridging For Network Simulator 3. SPB Shortest Path Bridging SPBM SPB Mac-in-Mac SPBV SPB Q-in-Q STP Spanning Tree Protocol. Shortest Path Bridging (SPB) resolves the main problems of STP’s data plane. 802.1aq Shortest Path Bridging is being standardized by the IEEE as an evolution of the various spanning tree protocols. 802.1aq allows for true shortest path Ethernet forwarding, multiple equal cost trees, much larger native Ethernet topologies, faster. 802.1aq Shortest Path Bridging is being standardized by the IEEE as an evolution of the various spanning tree protocols. 802.1aq allows for true shortest path routing, multiple equal cost paths.
Is network complexity impacting your ability to be agile? Are you looking for ways to enhance the security of your network that don’t compound complexity? Are you one of the estimated 89% of organizations that haven’t fully leveraged the power of network automation?
If yes, then read on to discover SPB. SPB stands for Shortest Path Bridging. It is the IEEE standard 802.1aq, which enables solutions over any fiber/copper/media topology, with unparalleled redundancy and re-convergence speed upon path or node failure. SPB combines the best of Ethernet with the best of IP by creating a multi-path Ethernet network that leverages IS-IS routing to dynamically build a topology between nodes. Traffic always takes the shortest, most efficient path from source to destination, guaranteeing optimal performance and failover. The Magic of Shortest Path Bridging. SPB is highly secure.
SPB greatly simplifies the data network. SPB is extremely flexible – support any physical topology. SPB was designed from ground up to support virtualization. SPB is scalable. SPB is faster to deploy. SPB is easier to troubleshoot. SPB lowers cost.
SPB has support for multicast traffic routing natively built in. SPB is an open industry standard, IEEE and IETF. SPB uses a link state routing protocol to allow switches to learn the shortest paths through an Ethernet fabric and dynamically adjust to topology changes.
With SPB you can build large loop-free multipath equal cost topologies. Feel free to use all physical layouts like star, ring, full mesh or whatever you prefer. SPB allows Ethernet networks to deploy multiple active paths to overcome the traditional active-passive redundancy of Spanning Tree, in which half of all ports could be in a non-forwarding mode. SPB replaces the traditional networking stack of over 20 traditional networking protocols and simplifies them into one protocol in one layer. SPB can provision millions of network segments automatically, both between and within sites.

This drastically simplifies the network segmentation security problem by allowing security zones to easily span sites using SPB, over the top of service provider links such as MPLS. SPB was designed to scale to carrier networks, and it also allows enterprise networks to be deployed with multiple active paths. With SPB some features similar to what MPLS provides are obtained. Packets that will be forwarded across SPB fabric will have an extra “TAG” like the label in MPLS, when the packet is forwarded to its destination the “TAG” is removed on the access switch, so your SPB network will always look like one hub for connected hosts. This is called mac-in-mac encapsulation.
An additional benefit is that the encapsulation process adds a service identifier or I-SID that brings 16 million service IDs and eliminates the limit of 4000 VLAN IDs. On SPB you can run different services, so once SPB is running on a network you can configure the services you prefer to utilize. Multicast is drastically improved by using SPB’s virtualized L3 multicast routing service without the need for additional protocols.
