WebSep 6, 2024 · In the 5GC, there is only a single user plane network function – the UPF – for transport of data between the gNB and the core. In 5G, there is a one-to-many relationship between the GTP-U tunnel on N3 and the DRBs on the air interface. Each QoS flow on N3 is mapped to a single GTP-U tunnel. The gNB may map individual QoS flows to one … WebMay 29, 2024 · In addition, the SMF also specifies the UPF to send the End Marker packets on the old N3 user plane path. After the UPF receives the indication, the End Markers are constructed and sent to each N3 GTP-U tunnel toward the source NG-RAN, after sending the last PDU on the old path.

WebOct 11, 2024 · GTP-U Echo Response is sent for the GTP-U Echo Request received from SMF over GTP-U tunnel. If Response is not received for the GTP-U Echo Request, the UPF retries Echo Requests based on configured retransmission timeout and maximum retries. When retries are exhausted, the UPF initiates PFCP node Report Request including … WebGTP-U Criteria that must be met before GTP tunnel acceleration is enabled: Generic tunnel acceleration is enabled under Device Setup Management (in General Settings, Tunnel Acceleration is checked). GTP Security is enabled under Device Setup Management (in General Settings, GTP Security is checked).
WebBy default, supported firewalls perform tunnel acceleration to improve performance and throughput for traffic going through GRE tunnels, VXLAN tunnels, and GTP-U tunnels. Tunnel acceleration provides hardware offloading to reduce the time it takes to perform flow lookups and allows the tunnel traffic to be distributed more efficiently based on ... WebLocal GTP-U entity and tunnel identification ¶ GTP-U uses UDP for transporting PDU’s. The receiving UDP port is 2152 for GTPv1-U and 3386 for GTPv0-U. There is only one GTP-U entity (and therefor SGSN/GGSN/S-GW/PDN-GW instance) per IP address. Tunnel Endpoint Identifier (TEID) are unique per GTP-U entity.
