Virtual Bandwidth Management for Remote Branch Offices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprise networks face challenges in managing network bandwidth effectively, particularly at remote branch offices where physical bandwidth management infrastructure is not readily deployed, leading to network congestion and inefficient resource allocation.
Innovation Solution
The implementation of network application traffic management devices at data centers, which coordinate to manage network traffic at remote branch offices without the need for physical devices at those locations, using partitioning mechanisms and algorithms to allocate bandwidth hierarchically and enforce traffic controls across access links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical bandwidth management devices are deployed at remote branch offices, then bandwidth management capability is improved, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent introduces data center network devices as intermediary components that remotely manage bandwidth at branch offices. These devices at data centers act as mediators, controlling and monitoring traffic flows through branch offices without requiring physical presence at remote locations. The intermediary devices establish virtual connections and enforce bandwidth policies remotely, resolving the contradiction by providing management capability while avoiding complex local infrastructure deployment.
Solution Approach 2:
The patent implements virtual bandwidth management by creating a virtual representation of bandwidth control capabilities at remote branch offices through centralized data center devices. Instead of deploying physical devices at each branch, the system creates virtual instances of bandwidth management functionality that are remotely instantiated and controlled from data centers. This copying approach provides the necessary management capability without the complexity of physical deployment at every location.
2Productivity
If network traffic increases to support growing users and applications, then business functionality is improved, but network congestion increases
Solution Approach 1:
The patent segments network traffic into different categories and applies differentiated bandwidth management policies to each segment. By classifying traffic flows based on application type, priority, and business criticality, the system can allocate bandwidth resources efficiently across growing numbers of users and applications. This segmentation allows high-priority business applications to maintain performance while lower-priority traffic is managed during periods of congestion, resolving the contradiction between supporting increased productivity and preventing congestion.
Solution Approach 2:
The patent implements dynamic bandwidth allocation that automatically adjusts resource distribution based on real-time network conditions and business priorities. The system continuously monitors traffic patterns, user behavior, and application performance, then dynamically reallocates bandwidth to optimize business application performance during varying load conditions. This dynamic approach allows the network to adapt to growing productivity demands while preventing congestion through real-time resource adjustment.

AI summary
Control and management of bandwidth at networks remote from the physical bandwidth management infrastructure. Particular implementations allow network equipment at a plurality of data centers, for example, to manage network traffic at remote branch office networks without deployment of network devices at the remote branch office networks.
