Bottlenecks affect the performance of any type of system, even data transmission. The key focus for the operation of a high-performance transport network is to eliminate any potential bottlenecks that can slow this transmission. To accomplish this, the network must have certain characteristics and careful attention must be paid to the expansion of the network.
The key to any network’s optimal performance is to remember that it is only as strong as its weakest link. This concept heightens the importance of multiprotocol label switching (
Operators must also consider that the intelligent network cannot get in its own way. In other words, the core routing component cannot be a constraint when interacting with the Internet, network peers, and complicated internal networks; otherwise the “intelligence” of the network is negated by its own design. This goes against the concept of the high-performance
MegaPath (News - Alert) is one company focused on delivering and maintaining a consistent network infrastructure by using a series of techniques, such designing the
With MPLS, MegaPath can abstract the physical topology from the logical topology that is essential for the company when adding optimized routes and handling circuit failures. MPLS enables MegaPath to address these issues in such a way that a high degree of flexibility and performance is delivered. MegaPath can also leverage MPLS to enable the creation of additional logic to determine the network pathways used by the traffic traversing the network.
To optimize the value of the
MegaPath also uses an interior routing protocol MegaPathto handle the inter-network device reach-ability and run the border gateway protocol to pass internal routes around the network. All internal routing is maintained, so decisions can be made as quickly as possible. If an outage occurs, the technology in place with MPLS handles network failures transparently, so they do not impact network services.
MPLS, MegaPath maintains a partial MPLS mesh that enables the network to be broken into several components. These direct network ring paths, direct market connections, and various tertiary paths are used for redundancy in the event of significant network outages. Fast reroute allows the logical topology to update itself in the event of an outage along the traffic path.MPLS topology. This offers several advantages over a traditional network design, but simply having MPLS does not guarantee the operator will experience improved network performance. It does offer an additional toolset beyond standard routing protocols to determine the improved network path. MPLS solution. MPLS), and the role it plays in the intelligent network.Susan J.
