Survivability of interconnected ring networks
… for survivability exists in most communication networks. Fiber optic networks concentrate large amounts of traffic within a few spans, using their high capacity to achieve a cost advantage. It is crucial to incorporate survivability at minimum cost in the design of such networks. This problem is …

Congestion control in resilient packet ring networks
The Resilient Packet Ring (RPR) is a new metro technology; RPR shares SONET's ability in providing fast recovery from link and node failures as well as inherits the cost and simplicity of Ethernet. RPR, like SONET/SDH, is a ring based architecture consisting of two optical rotating rings …

Running in circles : packet routing on ring networks
I analyze packet routing on unidirectional ring networks, with an eye towards establishing bounds on the expected length of the queues. Suppose we route packets by a greedy "hot potato" protocol. If packets are inserted by a Bernoulli process and have uniform destinations around the ring, and if …

Multicomputer Interconnection Using Word Parallel Shift Register Ring Networks
… structures and investigates the word-parallel ring network in detail. It proposes a design for constructing a multimicrocomputer using such a network. The ring network operates as both a memory switch interconnecting processor nodes and shared memory, and as a high speed block transfer medium …

Novel algorithms for fair bandwidth sharing on counter rotating rings
Rings are often preferred technology for networks as ring networks can virtually create fully connected mesh networks efficiently and they are also easy to manage. However, providing fair service to all the stations on the ring is not always easy to achieve. In order to capitalize on the advantages …

A recursively defined computer network
… comparison is made between triangles and various ring networks in order to show the meritt of the proposed topology. The research also leads to the definition of 'connectivity polynomials' and to a general formula to compute the connectivity of a network for a given number of failed links as a …

Study of Spin Configuration of Hexagonal Shaped Ferromagnetic Structures
… thickness range. By arranging the hexagons in ring networks, we found that there is an occurrence of alternating chirality configuration in the vortices when the inter-element spacing is small. The results imply that, in addition to the strength, the symmetry of the stray field also plays an …

Dynamic resource allocation in WDM networks with optical bypass and waveband switching
… allocation and node complexity in WDM optical networks Chapter 2 considers networks where the nodes have full wavelength accessibility, and investigates link resource allocation in ring networks in the form of the routing and wavelength assignment problem. In a ring network with N nodes and P …

PERFORMANCE OF A ROBUST MULTIPLE-RING, MULTIPLE-TOKEN NETWORK
Analytical and simulation studies of multiple-ring Token Ring Networks (TRNs) in which all nodes are connected to all rings [4,5] show that the packet transfer delay improves with the number of rings connected to each node. However, such multiple-ring TRNs are not economically feasible as the cost …
