Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
xGW(SGW/PGW)
SGW(Serving Gateway)
The SGW node handles the user data traffic, but isn’ t responsible for the signaling data used. It transports IP data from UE’s to the LTE Core Network. The SGW also routes incoming and outgoing IP packets for better system collaboration and serves as an anchor for the UE when it moves from one eNodeB to another.
PGW (PDN Gateway)
PGW is the network node that connects the EPC to external IP networks. What the PGW does is that it routes packets to and from external IP networks. Beyond that, it also allocates an IP address to all UEs and enforces different policies regarding IP user traffic such as packet filtering.

IPLOOK's Virtualized SGW/PGW The integrated xGW(SGW and PGW) enables virtualized network functions
- IPLOOK has combined SGW and PGW in LTE into one component xGW. Both of these two elements can be deployed as virtualized element. The SGW and PGW functions could be realized as a single network element.
- The SGW and PGW software processes support standard 3GPP interfaces and are interoperable with the products of other vendors.
- IPLOOK xGW processes can also be distributed in a number of different ways:
▫ A single instantiation, centrally located in a data center
▫ Separate instantiations, distributed remotely
▫ An integrated model, in which some processes are located centrally and others are distributed remotely

FAQ
What is IPLOOK’s xGW solution?
IPLOOK’s xGW is a virtualized LTE gateway solution that combines the SGW (Serving Gateway) and PGW (PDN Gateway) into a single integrated network function. It simplifies LTE core network architecture while delivering high-performance user data routing, mobility management, and policy enforcement capabilities.
What are the advantages of combining SGW and PGW into one xGW platform?
By integrating SGW and PGW into a unified solution, operators can reduce hardware requirements, simplify deployment and management, lower latency, and improve resource utilization. The architecture also reduces operational complexity and enables more efficient scaling in virtualized environments.
What deployment models are supported?
IPLOOK’s xGW supports flexible deployment models including centralized data center deployment, distributed edge deployment, and hybrid architectures that combine centralized and remote processing. It can run on COTS servers, cloud platforms, and NFV infrastructure.
How scalable is the xGW solution?
The platform supports deployments ranging from small-scale networks with 500 subscribers to carrier-grade environments with up to 10 million subscribers. Each instance can support throughput up to 30 Gbps, making it suitable for both enterprise and telecom operator use cases.
Does the solution support interoperability with third-party vendors?
Yes. IPLOOK’s xGW fully complies with standard 3GPP R14 interfaces and interoperates with third-party EPC components and eNodeB vendors. This allows operators to integrate the solution into existing multi-vendor network environments without vendor lock-in.
Which key functions are included in the xGW platform?
The solution supports session management, mobility management, IP address allocation, QoS control, charging functions, bearer establishment, paging, handover management, packet routing, and overload control. It also supports multi-PDN connectivity and lawful interception capabilities.
How does the xGW support mobility and roaming services?
The xGW acts as an anchor point during UE mobility between eNodeBs and supports interfaces such as S5/S8 for roaming scenarios. This ensures uninterrupted service continuity, seamless handovers, and stable connectivity for mobile subscribers across networks.
Is the xGW suitable for cloud-native and NFV environments?
Yes. IPLOOK’s xGW is designed for NFV deployment on COTS hardware and cloud platforms. Operators can virtualize gateway functions, dynamically scale network resources, and accelerate service deployment while reducing infrastructure costs and improving operational flexibility.
