BAG stands for bandwidth allocation gap, this is one of the main features of the AFDX protocol. This is the maximum rate data can be sent, and it is guaranteed to be sent at that interval. When setting the BAG rate for each VL, care must be taken so there will be enough bandwidth for other VL's and the total speed cannot exceed 100 Mbit/s.
Bandwidth allocation is the process of assigning radio frequencies to different applications. The radio spectrum is a finite resource, which means there is great need ...
Transmissions onto an Avionics Full-Duplex Switched Ethernet (AFDX) network are required to be limited to a Bandwidth Allocation Gap (BAG). Conformance to this BAG (and maximum transmission jitter) is then checked in the network switches in a similar way to UPC in ATM networks.
Dynamic bandwidth allocation using resource reservation multiple access schemes or statistical multiplexing, for example Spread spectrum and/or packet radio; Channel-dependent scheduling, for instance Max-min fair scheduling using for example fair queuing; Proportionally fair scheduling using for example weighted fair queuing
Dynamic bandwidth allocation is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth. [1] This is a form of bandwidth management , and is essentially the same thing as statistical multiplexing .
The consumed bandwidth in bit/s, corresponds to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path.The consumed bandwidth can be affected by technologies such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth ...
With both AFDX and TTEthernet, there are additional functions required of the interfaces, e.g. AFDX's Bandwidth Allocation Gap control, and TTEthernet's requirement for very close synchronization of the sources of time-triggered data, that make it difficult to use standard Ethernet interfaces.
The Bandwidth Allocation Protocol, along with its control protocol, the Bandwidth Allocation Control Protocol, is used to add and remove links in a multilink bundle over PPP, and specifying which peer is responsible for making decisions regarding bandwidth management.
