Synchronous Virtual Pipe
When realizing pipeline forwarding a predefined schedule for forwarding a pre-allocated amount of bytes during one or more time frames along a path of subsequent switches establishes a synchronous virtual pipe (SVP). The SVP capacity is determined by the total number of bits allocated in every time cycle Time is the continuous progression of existence that occurs in an apparently irreversible process, irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequ ... for the SVP. For example, for a 10 ms time cycle, if 20,000 bits are allocated during each of 2 time frames, the SVP capacity is 4 Mbit/s. Pipeline forwarding guarantees that reserved traffic, i.e., traveling on an SVP, experiences: # bounded end-to-end delay, # delay jitter lower than two TFs, and # no congestion and resulting losses. Two implementations of the pipeline forwarding were proposed: time-driven switching (TDS) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pipeline Forwarding
Pipeline forwarding (PF) ."applies to packet forwarding in computer networks the basic concept of '' pipelining'', which has been widely and successfully used in computing — specifically, in the architecture of all major central processing units (CPUs) — and manufacturing — specifically in assembly lines of various industries starting from automotive to many others. Pipelining is known to be optimal independent of the specific instantiation. In particular, PF is optimal from various points of view: # ''High efficiency in utilization of network resources'', which enables accommodating a larger amount of traffic on the network, thus lowering operation cost and being the foundation for accommodating the exponential growth of modern networks. # ''Low implementation complexity'', which enables the realization of larger and more powerful networking systems at low cost, thus offering further support to network growth. # ''High scalability'', which is an immediate consequence of the ...
