IEEE 802.1aq is an amendment to the IEEE 802.1Q networking standard which adds support for Shortest Path Bridging (SPB). This technology is intended to simplify the creation and configuration of Ethernet networks while enabling multipath routing .
The virtual LANs can be deterministically assigned to the different multi paths providing a degree of traffic engineering in addition to multipathing and can grow or shrink with simple membership changes. 802.1aq is fully backward compatible with all 802.1 protocols. 802.1aq became an IEEE standard in April 2012.
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association. ... Incorporated into 802.1Q-2014 802.1aq-2012: Shortest Path Bridging (SPB)
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
IEEE 802.1aq (Shortest Path Bridging) is an alternative to MC-LAG that can be used for complex networks. [5] TRILL (TRansparent Interconnection of Lots of Links) facilitates an Ethernet to have an arbitrary topology, and enables per flow pair-wise load splitting by way of Dijkstra's algorithm, without configuration and user intervention.
IEEE 802.1aq, also known as Shortest Path Bridging (SPB), allows redundant links between switches to be active through multiple equal cost paths, and provides much larger layer-2 topologies, faster convergence, and improves the use of the mesh topologies through increased bandwidth between all devices by allowing traffic to load share across ...
ECMP animation using IEEE 802.1aq protocol. Equal-cost multi-path routing (ECMP) is a routing strategy where packet forwarding to a single destination can occur over multiple best paths with equal routing priority. Multi-path routing can be used in conjunction with most routing protocols because it is a per-hop local decision made independently ...
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
