Redundant information

In this chapter, students will be able to understand: Routers receive packets and use the most efficient path to forward them to their destinations, complex internetworks can have redundant routers that provide multiple paths to the same destination, routers store information about the network in a routing table,...

Sentence Clustering is often used as a first step in Multi-Document Summarization (MDS) to find redundant information. All the same there is no gold standard available. This paper describes the creation of a gold standard for sentence clustering from DUC document sets. The procedure of building the gold standard and the guidelines which were given to six human judges are described. The most widely used and promising evaluation measures are presented and discussed. regenerated from all/some sentences in a cluster (Barzilay and McKeown, 2005). ...

Data transmission can contain errors. – Single-bit. – Burst errors of length n. (n: distance between the first and last errors in data block) • How to detect errors. – If only data is transmitted, errors cannot be detected. Send more information with data that satisfies a special relationship. -Add redundancy

GUIDELINE 3: Relations should be designed such that their tuples will have as few NULL values as possible  Attributes that are NULL frequently could be placed in separate relations (with the primary key)  Reasons for nulls: attribute not applicable or invalid attribute value unknown (may exist) value known to exist, but unavailable

For each weak entity type W in the ER schema with owner entity type E, create a relation R and include all simple attributes (or simple components of composite attributes) of W as attributes of R. In addition, include as foreign key attributes of R the primary key attribute(s) of the relation(s) that correspond to the owner entity type(s). The primary key of R is the combination of the primary key(s) of the owner(s) and the partial key of the weak entity type W, if any.

Which two statements are true of EIGRP topology depth? (Choose two.) Topology depth should be limited to 15 routers. Redundant links and alternative paths can be used to reduce topology depth. Topology depth is the maximum hop count between any two EIGRP routers in the topology. Route summarization can reduce the convergence time in networks with large depth. Topology depth is the number of router hops necessary for traffic to reach from access layer to core layer. Topology depth refers to the total number of hops that information must travel to reach all EIGRP routers in the network....

Offers hierarchy—each layer has specific role • Modular topology—building blocks • Easy to grow, understand, and troubleshoot • Creates small fault domains—clear demarcations and isolation • Promotes load balancing and redundancy • Promotes deterministic traffic patterns • Incorporates balance of both Layer 2 and Layer 3 technology, leveraging the strength of both • Can be applied to all campus designs; multilayer L2/L3 and routed access designs
