Study Notes

ASN.1

A machine independent data description language
Basic building block of an ASN.1 specification is a module
ASN.1 lexical convention must start with an uppercase letter for Type Identifier, and a lowercase letter for Value Identifier
ASN.1 lexical convention with two hyphens ("--") and terminated either by another set ("-") or the end of line character are comments
ASN.1 lexical convention may begin with a letter, and may contain letters, digits, and hyphens, but may not end with a hyphen or contain two consecutive hyphens is called an Identifier
ASN.1 data types derived from other types are called Tagged
ASN.1 data types that are atomic types and with no components are called Simple
ASN.1 simple types which is define as the set of values associated with information objects allocated by the standard is called an Object Identifier
ASN.1 structured types lists of alternatives are called Choice
ASN.1 structured data types which is collection of a large number of variables of the same type and whose order is significant is called Sequence of
ASN.1 data type that has a collection of one or more types is called a Set

Network Design

Traditional Network Design includes only network analysis phase and implementation phase
Network Design Tools are not part of Needs Analysis
Risk Assessment is not part of Cost Assessment deliverables
Security is not part of the Building Block Approach to network design
Upgrade Costs are not included in Costs to consider in Network design
The key deliverable for the needs assessment stage is a Set of Network Maps
Baselining is a network design technique where the designers must review the applications currently used on the network and identify their location so they can be connected to the planned network.
Network requirements should be organized into mandatory requirements, desirable requirements, and wish list requirements
The object on needs analysis, which describes what network elements will be needed to meet the organization's needs is called a Logical Network Design
RFP creates a competitive environment for providing network equipment and services
RFP checklists includes Choice sets of possible network designs; Mandatory, desirable, and wish list items, Security and control requirements; Response time requirements; Guidelines for proposing new network designs are called Network Requirements
RFP considerations which include implementation time plan; training courses and materials; support services; reliability and performance guarantees are called Service Requirements
A network design parameter where the number and type of users that will generate network traffic may need to be reassessed are Network Users

Cisco Network Models

Cisco Enterprise Architecture is designed to provide network planners with a roadmap for network growth as the business moves through different stages
Cisco Data center architecture where employees, partners, and customers rely on resources in the data center to effectively create, collaborate, and interact
Cisco Branch Architecture module that allows businesses to extend the applications and services found at the campus to thousands of remote locations and users or to a small group of branches.
Cisco Needs Categorization module that recommends that connections from home using broadband services such as cable modem or DSL connect to the Internet and from there to the corporate network.
Cisco Edge Architecture pertains to module that offers connectivity to voice, video, and data services outside the enterprise.

Network Infrastructure

Backbone Cabling runs up through the floors of the building (risers) or across a campus and provides the interconnection for equipment rooms and telecommunication closets.
Equipment Room is wiring standards that provides a termination point for backbone cabling that is connected to one or more telecommunication closets
Telecommunication Closet is also known as the Intermediate Distribution Facility (IDF)
Entrance Facility is a facility that may also contain campus-wide backbone connections.

Active Directory

Domains are collections of users, computers, groups, and so on
Domains are a logical partition in Active Directory database
Organizational units are used to organize resources to reflect administrative divisions and may not map to organizational structure

Network Technology

It describes how data are actually represented in terms of bit patterns while in transit is called Transfer syntax
It specifies the mapping from one syntax to another is called Encoding Rules
The sequence of octets used to represent a data value is called ENCODING
Macro Notation means estimating the size and type of the "standard" and "advanced" network circuits for each type of network.
Macro Instance is generated from a macro definition by substituting values for variables.
Abstract Syntax describes the generic structure of data
BER is widely used in defining transfer syntaxes

Other Key Terms

Data Types are a named set of values -- may be simple or structured
Teleworker Architecture design module that recommends that connections from home using broadband services such as cable modem or DSL connect to the Internet and from there to the corporate network.
Trees are structures where Child domains derive their namespace from parent
Access ,distribution , core are being considered in Geographic scope of the network design
It provides an operator interface to allow an authorized user to manage the network is called Network Management System
