Wide Area Networks TRIZ Cases
- Forced MAC Learning in Bridged Ethernet Networks
A constrained-based source-routing method uses path learning frames to establish connection-oriented paths through intermediate bridge nodes.
- Remote IP Address Allocation via Detection Packets
A client configures its network address using detection packets forwarded by an access router from a remote server.
- Enhanced Multicast VLAN Registration Bandwidth Conservation
Enhanced IGMP snooping eliminates multicast stream duplication across subscriber VLANs, conserving bandwidth in ring-based metro networks.
- Multi-Protocol Gateway for AMM Metering Networks
A multi-protocol gateway relays commands and alarms between smart meters and management systems.
- Controller Node for Broadband Access Control Sessions
A controller node resolves n:m relation bottlenecks by performing repository lookups to route identity information toward specific external service edge nodes.
- Hybrid Port Merging Layer 2 and Layer 3 Services
A hybrid port combines VLAN switching and MPLS routing on one interface to deliver diverse network services.
- Router Relay Proxy for ISP Network Bandwidth Optimization
Designating routers as relay proxies allows network devices to communicate directly, reducing ISP server bandwidth utilization and infrastructure costs.
- Prioritized Configuration Error Reporting in Virtual BRAS
A user plane network element selectively reports configuration errors to a control plane based on defined service priorities.
- ANCP Relay for Access Node Multi-NAS Communication
An ANCP relay routes messages between an access node and multiple network access servers, reducing device complexity by extracting intelligence from the node.
- Anycast Routing Device Credential-Based Server Selection
Credential-based routing directs anycast messages to specific provider servers, resolving load imbalance and service specificity issues.
- Virtualized BRAS Protocol Component Dynamic Capacity Control
A virtualized broadband remote access server protocol component adjusts capacity by activating or hibernating instances within a shared resource pool.
- Stateless IP Routing via Embedded Affiliation Metadata
Processors embed affiliation metadata in IP addresses to route WAN traffic statelessly, eliminating complex dedicated software and stateful operations.
- LAN Traffic Shaping via Rules Engine and Sensor Feedback
Automated traffic shaping resolves the contradiction between manual configuration complexity and packet control quality by applying self-service feedback loops.
- Ethernet Access Network Traffic Diversion via Address Conversion
A routing node identifies peer-to-peer traffic and generates address conversion information to redirect packets through the access network.
- Remote Administration via Signaling Network Session Trigger
Administration equipment sends connection requests via a signaling network to trigger device sessions.
- Virtual BRAS Cluster Redundancy via Common Control Plane
A virtual BRAS cluster uses a common control plane to synchronize state across multiple chassis for seamless session takeover.
- Access Switch Network Link Allocation for Stable Transmission
Centralized node server allocates specific network paths to access switches, preventing packet loss and ensuring stable transmission rates under heavy loads.
- Automotive Switch Fabric Data Packet Segmentation
A vehicle switch fabric system segments large data records into smaller packets for network transmission.
- Network Device Automatic Parameter Configuration
A network device detects access protocols and automatically sets connection parameters.
- CPE DHCP Server Redundancy for Network Disconnection
Local DHCP servers on the CPE dispense addresses during virtual platform defects, ensuring continuous network functionality.
- Virtual Router Scaling for vWAN Throughput
Scaling virtual routers based on traffic load improves network throughput while managing system complexity.
