What emerging WAN remote connectivity service you recommend and why

I would recommend the Cingular Wireless WAN connectivity service . It provides a secure high-speed back-up to their wireline data connections in case those will be disabled by cable cuts , weather or local access outages . It can also be used as a primary data connection for companies with remote or temporary operations where there is no readily available wireline access , or those looking for a cost-effective and fast deployment

Discuss how MPLS is used to ensure QoS for mission critical applications

MPLS

has the QoS feature that represents the capability to provide distinct levels of service and resource assurance across an MPLS network . Its label stack entry has a 3-bit field for QoS priority . It also has a set of techniques required to manage network bandwidth delay , jitter , and packet loss like the ability to mark packets with a certain priority combined with buffer management and queuing schemes ensures that voice traffic remains within the acceptable bounds for packet loss , delay , and jitter

What is your choice for such a service and why would you select this particular service

Would you add multiple remote sites over a single physical connection at the central site

Adding multiple remote sites over a single physical connection would add ease to the network 's end users . However , it could also compromise the connection 's bandwidth capacity , so extra configurations must be set up However , in my chosen WAN service , it is readily configured and available

Discuss when it is appropriate to use broadband fixed wireless services

It is appropriate to use broadband fixed wireless services when the availability of such service is at hand in the chosen area of operation Its use is desirable if it is needed that the network should have a guaranteed data rate , so that the communication between remote sites will not be spoiled
