IEEE 802.1aq

Shortest Path Bridging (SPB), specified in the IEEE 802.1aq standard, is a computer networking technology intended to simplify the creation and configuration of networks, while enabling multipath routing.For non-experts, or non-technical readers SPB is an IEEE standard that combines many functions of routing, bridging, load balancing (link aggregration, multi-chassis link aggregation, equal-cost multi-path routing, network virtualization) and tunneling (virtual routing and forwarding, stealth networks, layer-2 virtual service networks (L2VSN), and layer-3 virtual service networks (L3VSN)) into a single easy to configure protocol, which can yield a variety of benefits such as better fault tolerance, increased bandwidth, and improved security.Shortest Path Bridging is the replacement for the older spanning tree protocols (STP) (spanning tree protocol IEEE 802.1D, rapid spanning tree protocol (RSTP) IEEE 802.1w, multiple spanning tree protocol (MSTP) IEEE 802.1s) that permitted only a single path toward the root bridge and blocked any redundant paths that could result in a layer 2 loop. SPB allows all paths to be active with multiple equal cost paths, and provides much larger layer 2 topologies (up to 16 million compared to the traditional virtual local area network (VLAN) limit of 4,096 specified in the IEEE standard 802.1Q). It also supports faster convergence times, and improves the efficiency of the mesh topologies through increased bandwidth and redundancy between all devices, allowing traffic to load share across all paths of a mesh network. To enhance resiliency in the access layer SPB can also be integrated with link aggregation functions, such as standards-based link aggregation (IEEE 802.1AX) and proprietary multi-chassis link aggregation (MC-LAG) implementations.The technology provides logical Ethernet networks on native Ethernet infrastructures using a link state protocol to advertise both topology and logical network membership. Packets are encapsulated at the edge either in media access control-in-media access control (MAC-in-MAC) 802.1ah or tagged 802.1Q/802.1ad frames and transported only to other members of the logical network. Unicast, multicast, and broadcast are supported and all routing is on a symmetric shortest paths.The control plane is based on the Intermediate System to Intermediate System (IS-IS), leveraging a small number of extensions defined in Request for Comments(RFC) 6329.
