Networks Interconnection TRIZ Cases
- SDN Controller End-Station Identification Across NAT
OpenFlow controller extracts pre-NAT IP addresses and maps them via hash values, resolving information loss without modifying legacy end-stations.
- TRILL Network Frame Routing via Service VLAN Identifiers
Service VLAN identifiers route TRILL frames through existing bridges, overcoming the 4096 VLAN limit and hardware constraints.
- Hardware MEP Search via ACL Packet Parsing
Hardware-based packet parsing identifies Maintenance End Points without software processing, eliminating CPU overload and improving performance.
- Graph-Based Network Fabric for Cloud Visibility
A graph-based network fabric manages virtualized traffic flows, resolving architecture complexity and performance degradation in public cloud monitoring.
- Multi-service VPN Client Dynamic Protocol Failover
A multi-service network client establishes secure enterprise connectivity on mobile devices using integrated security and acceleration modules.
- TRILL Remote Port Mirroring via Encapsulation
TRILL encapsulation preserves original packet headers for remote port mirroring.
- Hybrid Wireless Mesh Network Path Optimization
Centralized server coordinates hybrid wireless mesh nodes to determine optimal data transmission paths, reducing battery drain and network congestion.
- Moving Target Defense Protocol Obfuscation
Obfuscates protocol identifiers with faux headers and nonce permutations, increasing attacker uncertainty while managing data packet size overhead.
- Distributed Tunnel Aggregation for MSR Capacity Scaling
Segmented tunnel aggregators reduce managed security router routing burdens and latency by distributing encapsulation operations across the network.
- Adaptive Sub-Tunneling for Bandwidth Oversubscription
Adaptive sub-tunneling monitors resource utilization to adjust bandwidth allocation, resolving oversubscription and saturation in network tunnels.
- Hard Disk Controller MCTP Out-of-Band Management
A hard disk manager generates MCTP packets to enable out-of-band control of SAS or SATA drives via the controller.
- Link Aggregation Port Signal Degradation Detection and Protection Switching
A link aggregation port detection system monitors member port attenuation levels to trigger carrier-grade service protection switching.
- Active-Active Logical Service Router Session Consistency
Hash functions map tuple information to logical service routers, maintaining session consistency and throughput in active-active SDN environments.
- VXLAN RSS Queue Allocation for Multi-Core Processing
A load balancer instructs a physical network interface to allocate Receive Side Scaling queues for VXLAN encapsulated packets.
- DNAT-T Proxy Server for Multi-NAT VPN Traversal
A DNAT-T proxy server synchronizes external IP and port allocations to establish bilateral data traversal channels through multiple NATs.
- BGP Flow Spec Protocol Resource Association via Global Identifier
A BGP Flow Spec controller uses a global identifier to associate forwarding resources within extended community attributes.
- PCIe Network Management via Out-of-Band Ethernet Segmentation
Segmenting high-speed data transfer from control operations allows the system to add fault tolerance and quality of service without increasing complexity.
- EVPN VPLS Interoperability via Primary Mirrored Pseudowire Labels
Segmenting pseudowire label space into primary and mirrored components eliminates MAC flip-flopping in all-active multi-homed EVPN deployments.
- Virtual End-Point Mobility for Traffic Engineering Tunnels
Virtualized end-points allow automatic migration of ingress and egress locations, eliminating manual reconfiguration during network evolution.
- Relay Server Virtual Address Allocation for Secure Inter-LAN Routing
A relay server allocates virtual addresses to terminals and translates packets between these identifiers and actual IP addresses.
- Security Appliance Default Gateway for Ransomware Lateral Movement
A security appliance acts as a default gateway to force endpoint traffic through point-to-point links, preventing ransomware lateral movement in shared VLANs.
