Remote Network Requirements

The central site must:

Provide secure and reliable access to resources forremote users.

Accommodate many types of WAN connections fromremote locations.

Remote sites:

Branch office A remote location thataccommodates employees who have a reason to belocated away from the central site. A branch office isalso called a remote site or remote office.

SOHO site A small office with one to severalemployees or the home office of a telecommuter.

Mobile workers sites Remote locations for mobileusers who tend to access the company network using

an asynchronous dialup connection or access thecor orate intranet usin broadband Internet service.

Setting Up WAN Connections for Remote Sites

Factor Options

Multiple access options Leased line, broadband, MPLS, FrameRelay, VPN, ISDN

Cost Permanent, on-demand, public or private

Access control Router and firewall rulesets

Secure connectivity IPsec or MPLS VPN

Authentication Remote to central

Redundancy Duplicate services in case of failure

Infrastructure availability Not all services are available in all areas



Example: Integrated Services for SecureRemote Access



Intelligent Information Network

Intelligent Information Network (IIN) integratesnetworked resources and information assets.

IIN extends intelligence across multiple products andinfrastructure layers.

IIN actively participates in the delivery of services andapplications.

Three phases in building an IIN are:

Integrated transport

Integrated services

Integrated applications



Cisco SONA Framework

The Cisco Service-Oriented Network Architecture(SONA) is an architectural framework.

SONA brings several advantages to enterprises:

Outlines how enterprises can evolve towards the IINIllustrates how to build integrated systems across afully converged intelligent network

Improves flexibility and increases efficiency



Cisco SONA Layers



Self Check

1. What are the 3 layers included in the traditional

hierarchical model?

2. What 3 types of remote sites that must beaccommodated at the central site?

3. What are some examples of the types of WANtechnologies used to connect a remote site to thecentral site?



Summary

The traditional three-layer hierarchical model no longer

completely meets the needs of large enterprise networkswith remote sites.

Cisco Enterprise Architecture integrates the entirenetworkcampus, data center, branches, teleworkers,

and WANto provide secure access to all tools,processes, and services across all sectors of thecompany.

Providing secure remote access is a key feature of Cisco

Enterprise Architecture. The infrastructure layer of SONAaddresses remote access.

IIN aligns IT resources with business priorities.

Cisco SONA provides an evolutionary path to IIN.
