Bandwidth to Support Convergence
Convergence means combining or converging voice, data and video
onto a single network. Enterprises usually need to expand their
LAN bandwidth and set up a QoS or Quality of Service priority
system to give priority to real-time streams such as telephone
calls or video conference feeds, which are more sensitive to network
delays than data transfers. Most often, the common protocol for
convergence is IP.
What are Typical Classes of Service?
Class of Services or CoS is established in MPLS networks to ensure the performance of each packet on the network. CoS classes include real time for voice and video, mission critical for time sensitive applications such as transaction processing, business critical for applications such as database access, and data for lower priority traffic that isn't time sensitive.
Transparent LAN Service
VPLS is sometimes called Transparent LAN service. That’s because WAN communications moves from level 3 to level 2. Your connection to the network is via a managed edge switch that is provided by the network operator. The inherent broadcast nature of Ethernet is preserved, creating a “plug and play” environment as new services are added to the network and discovered by other members connected to the VPLS.
Cost Advantage of Converged Networks
By merging voice, data and video onto a single network, the cost and support levels needed to maintain separate computer data, telephone and video networks is reduced to a single network staff. WAN networks may also be managed by the provider, if desired.
MPLS Network Configurations
The MPLS network can be thought of as a cloud that is accessible from many locations. Your service can be set up for a single point to point connection, a hub and spoke replacement for central offices serving many remote locations, or a fully meshed network where any site can communicate with any other site.
