Summary

Designing, implementing, supporting and managing a wide area network is a huge

task even for the largest organisations. A technology exists today that helps small and

medium sized businesses resolve all the issues surrounding network management. It

is called Multi Protocol Label Switching (MPLS) and is easy to deploy, reduces network

management time and reduces costs.

Overview

MPLS - Multi-Protocol Label Switching[def] - a way of securely connecting multiple offices that promotes collaboration improves business resilience

Imagine being able to interconnect all of your offices to each other seamlessly, while housing

business critical resources in a central class 1 datacentre enabling access to all users across a

secure and resilient infrastructure. Trying to manage business critical tools in several, disparate

locations means that you create multiple points of failure, multiple environments to manage

and a potentially complex network infrastructure to maintain and support.

Imagine your business could enjoy true private networking but without costly security

firewalls at each site that each require resource and know-how to manage, and have

the ability to filter Internet access at one easily controlled point. Imagine implementing

new applications, such as Microsoft Exchange, combined voice/data networking and

videoconferencing, with ease.

A technology exists today that helps small and medium-sized businesses resolve all of these

issues. It is quick to deploy, reduces network management time compared with individual

sites and is cost-effective. It is called MPLS.

Sounds too good to be true?

Not any more! Connecting multiple, disparately located, offices, depots, temporary sites and mobile workers

into one corporate network is one of the biggest technology challenges for any growing

business. Traditionally it has required significant levels of investment to provide the dedicated

security, access control and dedicated line at each site. Connecting and maintaining multiple

offices also required a level of technological knowledge that extended beyond basic

IT literacy.

In essence, MPLS gives you the ability to build a private network over a public infrastructure,

so you don’t need expensive leased lines at each site.

An MPLS network also provides significantly higher levels of security than an IPSec VPN;

an intruder can try to connect to a computer using a VPN because they are all publicly

addressable. This may give multiple points of entry into your corporate network that need

to be managed and secured. An MPLS network is a true private network and has no public

addresses, any potential intruders are not given a window on to your corporate infrastructure.

Simply put, MPLS offers the flexibility of a public routed network with the speed and security

of a private network. Traffic can find its way quickly to an end point while also allowing the

underlying infrastructure network to be shared securely.

Prove it!If you are still thinking that MPLS sounds too good to be true, offering increased data

security levels, protection against unwanted, often malicious intruders, while costing less

than traditional IPSec VPN solutions and needing less management time, here is a little

more detail on why MPLS technology really can add value to your business.

Security:Despite the ability to set up secure ‘tunnels’ of encrypted traffic between two branch

offices using an IPSec VPN, a network is still potentially o pen to attack. MPLS removes

that particular vulnerability in one fell swoop because it has no publicly addressable

terminals. It also gives IT managers a single network to manage, rather than one at each

site, enables virus protection, malware detection and Internet monitoring.

ManageabilityReducing the amount of time needed to administer a multi-site network is critical for small

and medium-sized businesses. A large part of the day-to-day management is ensuring the

network is secure and protected from malicious attacks.

Conventional private networks that are connected to the public Internet need firewalls

and lots of them if there are multiple locations on the network. Administering firewalls,

with all the rules and updates, can be a complex task that needs well-trained operators, and

so is a significant overhead for growing businesses. While firewalls are an obvious choice for

outsourcing to providers such as Star to manage, they can be eliminated altogether at branch

level with MPLS.

“Simply put, MPLS offers the flexibility of a public routed network with the speed and security of a private network.”

Manageability is not just about direct security, but also about monitoring employee access to

the Internet to ensure they are not visiting inappropriate (as defined by an Acceptable Usage

Policy) or non-work related websites. With a traditional IPSec VPN this would require filters

set up at each location. Access to the Internet on an MPLS network however, can be through

a single point on the provider’s network; so all incoming and outgoing traffic can be easily

subject to a consistent set of rules and filters, and also to

email spam and content management.

PerformanceMPLS networks perform significantly better than IPSec VPNs because there is no need to

encrypt data as a result of its higher levels of security. Encrypting/decrypting data can be

a costly venture, and has an impact on the performance of a corporate network.

Should your business require ‘belt and braces’ peace of mind, MPLS traffic can be encrypted.

Another performance benefit of MPLS over IPSec VPNs is a quality of service. While MPLS

doesn’t quite go as far as guaranteeing end-to-end performance, you’d need to implement a

very costly solution to do that, it does allow traffic prioritization. The true benefits of this will

only be realized when a link reaches its capacity, but it does provide a degree of scalability for

fast-growing businesses who need to improve network performance until they can invest in

additional bandwidth.

FlexibilityMPLS’ true value is all about the services you can implement in the MPLS ‘cloud’, the data

centre, firewalls, email management, application hosting etc., it’s much more than just a

replacement for a wide area network.

MPLS allows up to 64 different types of service. It enables the set up of multiple virtual

networks; while it is straightforward to bring a community of home users into the network,

you may prefer to have a different acceptable use regime for accessing the internet, while

still allowing the same access to corporate applications, for example.

Star recommends defining three levels of traffic on an MPLS network - one for voice,

one for priority traffic such as console applications, and one for everything else. Email,

for example, doesn’t suffer if it takes a few extra milliseconds to send – but for other

enterprise applications where there are regular, repetitive processes to access data

performance degradation will be obvious.

“...it’s much more than just a replacement for a wide area network.”

MPLS and your businessMPLS is a mature technology, celebrating its 10th birthday this year. Star has implemented

more than 150 systems for its customers.

Star can help you find the right solution for your business and work with you to help migrate

from your existing network to an MPLS system.

However you interpret MPLS for your business, its benefits will be experienced across the

organisation. From greater efficiency and enhanced Inter-working, to security and resilience

and the capability of handling new, demanding applications such as those that use converged

voice/data, real time video, and peer-to-peer applications, MPLS delivers a compelling solution

for growing small and medium-sized businesses. It also comes at a price that fits, won’t break

the bank and reduces capital and operational costs, while reducing the resource needed to

mange your multi-site network at the same time.

Analysts are planning for this year to be the coming age of MPLS. The functionality and

stability of its implementations using equipment from established providers such as Cisco

now mean that small and medium-sized businesses can benefit from a virtual ‘cloud’ that

can encompass almost all IT and telecoms applications and services.

Cisco-powered NetworksMore than 300 of the most successful service providers around the world offering one or more

services, have earned the Cisco-powered designation. These providers offer a wide range of

services for small and medium-sized businesses. From the basics of Internet connectivity and

web hosting to managed services, they should be your first choice when you need to manage

your critical business functions. Star is one of thirty-five Cisco-powered Network providers in

the UK. A sole focus on small and medium-sized businesses makes Star unique among Cisco’s

UK partners.
