Texas-based NPE Parity Networks LLC has filed its first litigation, asserting six patents (6,252,848; 6,738,378; 6,763,394; 7,002,958; 7,103,046; 7,107,352) generally related to network traffic management against Huawei (6:16-cv-01306). The company is accused of infringement through the provision of enterprise network routers that utilize Multipath Label Switching (MPLS), a technology for routing data packets using shorter “labels” rather than longer network addresses. Also at issue are various Huawei gigabit Ethernet switches that include certain traffic management features and processors.
