I. INTRODUCTION

The implementation of a Service Ready Medium Branch Network enablesenterprises with branch offices of 50 to 100 users to deploy high-value networkservices such as unified communication and application optimization on top of a

secure branch network infrastructure that is connected to a campus or data centercore (central site) over a variety of WAN technologies. The goal of the ServicesReady Medium Branch Network is to make deployment of these services fast,simple, and predictable.

The design, test and deployment of this Services Ready Medium Branch Networkwill focus on the key elements to ensure the consistent connectivity and mandatorysecurity requirements for data, voice, and application optimization services.

II. DESIGN CONSIDERATIONS

WAN Services

Layer 3 Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN)for increased flexibility and reduced bandwidth cost

Dedicated bandwidth ranging from 6 to 44 Mb/s to handle data, voice, andvideo traffic

LAN Services

Hierarchical network design to simplify deployment, troubleshooting, andmanagement

Connectivity to branch devices at Fast Ethernet or Gigabit Ethernet speeds Near-wire-speed performance between all devices Provisions for accommodating future expansion Networking device redundancy without traffic loops Power-over-Ethernet (PoE)

Network Fundamentals

High availability, rapid recovery, and disaster recovery Rapid recovery in case of component failure Automatic switchover to backup WAN link that has a minimum one-quarter of

the bandwidth of the primary WAN link Ability to restore service within 24 hours in the event of a disaster Quality of service (QoS)


4/24

3

Application-specific traffic prioritization both within the branch office andacross the enterprise

Bandwidth management for WAN-based traffic Provisions for IP telephony, business video, critical and bulk data applications Provisions to mitigate denial of service (DoS) and worm attacks Identification and classification of critical application flows for QoS IP routing and addressing Routing within the enterprise and between the branch and the service

provider network Direct Internet access from the branch Support for multicast applications Translation of private addresses and ports in order to access the Internet Dynamic allocation of IP addresses for end devices

Security Services

Infrastructure protection Physical securing of access to networking devices Disabling of unused services that may be used to exploit the network Authentication of routing protocol updates Access control Authentication and authorization services for controlling access to network

resources Logging capabilities for auditing access to network devices and resources Integration with global access management system to enforce access

privileges Secure connectivity Secure interoffice connectivity for full-mesh and hub-and-spoke WAN

topologies Secure access into the branch network for remote or home office workers Voice, video, and data separation on the LAN Separation of network management traffic Access to the server in the branch by home office users

Threat protection, detection, and mitigation Blocking of unauthorized traffic from entering or leaving the branch Access to servers in the branch by home office users Verification of source addresses for incoming traffic Identification and mitigation of common DoS attacks and worms Prevention of malicious attacks on the branch office network from outside Prevention of attacks and security breaches from within the branch office
