Pros of Open5GS

• Lightweight and efficient implementation of 5G core network functions
• Easier to set up and configure for small-scale deployments
• More focused on core network functionality, making it simpler for specific use cases

Cons of Open5GS

• Less comprehensive ecosystem compared to Magma
• Limited support for advanced features like network slicing and edge computing
• Smaller community and fewer integrations with third-party tools

Code Comparison

Open5GS (C language):

ogs_socknode_t *ngap_client(ogs_socknode_t *node)
{
    ogs_assert(node);
    ogs_assert(node->sock);

    node->poll.read = ngap_recv_handler;
    node->poll.write = ngap_write_handler;

    return node;
}

Magma (Python language):

def create_service(mconfig: MagmaD, loop: asyncio.AbstractEventLoop):
    """Create magmad service"""
    service = MagmaService('magmad', mconfig, loop=loop)

    # Start services
    service.loop.create_task(service.run())
    return service

The code snippets demonstrate the different languages and approaches used in each project. Open5GS focuses on low-level networking in C, while Magma uses Python for higher-level service management.

Pros of srsRAN_4G

• Focused specifically on 4G/LTE implementation, providing a more specialized solution
• Lighter weight and potentially easier to deploy for smaller-scale or research-oriented projects
• More active development and frequent updates

Cons of srsRAN_4G

• Limited to 4G/LTE, while Magma supports multiple generations (2G, 3G, 4G, 5G)
• Less comprehensive network management features compared to Magma's end-to-end solution
• Smaller community and ecosystem compared to Magma's backing by major tech companies

Code Comparison

srsRAN_4G (C++):

int srslte_ue_dl_decode_pdsch(srslte_ue_dl_t* q,
                              cf_t*           sf_symbols[SRSLTE_MAX_PORTS],
                              srslte_pdsch_cfg_t*  pdsch_cfg,
                              srslte_pdsch_res_t*  data)
{
  // PDSCH decoding implementation
}

Magma (Python):

def allocate_ip_address(self, sid: SubscriberID) -> AllocateIPAddressResponse:
    """
    Allocate an IP address for a subscriber.
    """
    # IP allocation implementation

The code snippets highlight the different focus areas: srsRAN_4G deals with low-level signal processing, while Magma handles higher-level network management tasks.

Pros of free5gc

• More focused on 5G core network implementation
• Lighter weight and potentially easier to deploy
• Stronger adherence to 3GPP standards

Cons of free5gc

• Less comprehensive ecosystem compared to Magma
• Fewer integrations with existing network components
• Limited support for legacy networks (2G/3G)

Code Comparison

free5gc (Go):

func (smf *SMF) HandlePDUSessionEstablishmentRequest(req *nasMessage.PDUSessionEstablishmentRequest) {
    // Implementation details
}

Magma (C++):

void MagmaService::HandleSessionRequest(const SessionRequest& request) {
    // Implementation details
}

Both projects aim to provide open-source 5G core network solutions, but they differ in their approach and focus. free5gc is more specialized in 5G core implementation, while Magma offers a broader range of features and network support.

free5gc is written primarily in Go, which can lead to easier deployment and maintenance. Magma, on the other hand, uses a mix of languages including C++ and Python, potentially offering more flexibility but with increased complexity.

Magma provides a more comprehensive solution for mobile network operators, including support for older network generations and integration with various network components. free5gc, while more focused on 5G, may be a better choice for those specifically looking to implement a standards-compliant 5G core network.
