At each functional layer of the network protocol, after minimizing the maximal load of links, the bottlenecks of the layer are discovered in a bottleneck detection process. At each iteration of the detection loop, we minimize the sending of traffic over all links having maximal loading, and being suspected as bottlenecks.
OSI layer 2 (data link layer, e.g. Ethernet frame in LANs or multi-link PPP in WANs, Ethernet MAC address) aggregation typically occurs across switch ports, which can be either physical ports or virtual ones managed by an operating system. Aggregation at layer 3 (network layer) in the OSI model can use round-robin scheduling, hash values ...
The existence of multiple layers (or dimensions) allows to introduce the new concept of network of layers, [3] peculiar of multilayer networks. In fact, layers might be interconnected in such a way that their structure can be described by a network, as shown in the figure. Network of layers in multilayer systems. The network of layers is ...
Cross-layer optimization is an escape from the pure waterfall-like concept of the OSI communications model with virtually strict boundaries between layers. The cross layer approach transports feedback dynamically via the layer boundaries to enable the compensation for overload, latency or other mismatch of requirements and resources by any control input to another layer, but that layer ...
The link layer corresponds to the OSI data link layer and may include similar functions as the physical layer, as well as some protocols of the OSI's network layer. These comparisons are based on the original seven-layer protocol model as defined in ISO 7498, rather than refinements in the internal organization of the network layer.
Multiprotocol label switching belongs to the family of packet-switched networks. MPLS operates at a layer that is generally considered to lie between traditional definitions of OSI Layer 2 (data link layer) and Layer 3 (network layer), and thus is often referred to as a layer 2.5 protocol.
The crypto firm Layer N announced on Wednesday a seed round of $5 million co-led by the Peter Thiel-backed Founders Fund and the decentralized investment group dao5, as well as Kraken Ventures and ...
In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer acts as an interface between the medium access control (MAC) sublayer and the network layer.
