In a network that includes multiple hops or segments from the ingress LSR to the egress LSR of the LSP, a broken LSP can present a significant troubleshooting task to an engineer. For example, the engineer must check the routing table and label forwarding table at the ingress and egress LSR...
paths or path segments to bypass the fault are established using the signaling protocol. Note that reroute mechanisms are inherently slower than protection switching mechanisms, since more processing and configuring must be done following the detection of a fault. The advantage of reroute mechanisms is...
area --A logical set of network segments (for example, one that is OSPF-based) and their attached devices. Areas usually are connected to other areas by routers, making up a single autonomous system. OSPF and IS-IS define their areas differently. OSPF area bor...
approach when both objectives are measured using the Euclidean metric. The problem studied in [2] discusses a special instance of the problem studied here which proposes an algorithm for a set of vertical line segments as the obstacles. Here we study the problem for a set of polygonal obstacles...
2. More details can be found in the studies by Douglas Reynolds and Barbara Mittler in this volume. In the case of China, it might be argued that the great social changes at the end of the Ming, with large new segments of the population adopting urban and commercial lifestyles and becomin...
I normally have 3-4 natural resource segments in the portfolio that are somewhat countercyclical. When more economically sensitive segments have been weaker, we have seen the precious metals equity segment perform better. In 2022, with higher yields, we saw the shipping & fossil fuel segment compe...
virtual colors are assigned in order to handle the case where the network does not have sufficient redundancy for protection paths or in the case where fiber bundles are used. A network diagram illustrating an example optical network including WDM segments and non-WDM segments is shown in FIG. ...
