A Secure, Cloud Native Signaling Solution for the New 5G Core
Oracle 5G Service Communication Proxy (SCP) helps operators to efficiently secure and manage their 5G network by providing routing control, resiliency, and observability to the core network. Oracle’s SCP leverages IT service mesh (ISTIO) and adds critical capabilities to make it 5G-aware, thereby addressing many of the challenges caused by the new service- based architecture (SBA) in the 5G core.
SCP Business Benefits
Increases network efficiency by providing effective load balancing across 5G core network function instances
Provides visibility into the 5G core network
Eases the introduction and scaling of new services and features
Assists in reducing network complexity and maintenance cost
Helps Communications Service Providers (CSPs) to resolve interoperability issues and deliver better services to their customers

2 Service Communication Proxy System Architecture
This section explains the Service Communication Proxy
system architecture.
The Service Communication Proxy is a decentralized solution and composed
of control plane and data plane. This solution is deployed along side of 5G
Network Functions (NF) for providing routing control, resiliency, and
observability to the core network. The Service Communication Proxy has a
control plane and a data plane.
Figure 2-1 Service
Communication Proxy Architecture
The Service Communication Proxy solution is deployed either as a default
outbound proxy to NF instances or as a router model where SCP is configured as
2 outbound proxy at each NFs in cloud native environments. SCP provides the
following benefits to the 5G core network architecture:
Improved Load Balancing
Routing Control
Message Priority
Assignment/Override
Circuit Breaking and Outlier
Detection
Overload Control
Observability
Improved Load
Balancing
The 5G core network is a service based architecture which does not
lend itself to an efficient load balancing of provider NFs and by introducing
an Service Communication Proxy in the midst, load balancing across available
NFs can be significantly improved. The Service Communication Proxy has a
complete view of all the messages arriving for a given NF type and supports
schemes such as round robin, weighted round robin, transaction latency, etc
while factoring in the current load and NF availability.
By leveraging its position in the network, the Service Communication
Proxy provides better routing control and bring resiliency to the network. It
relieves user NFs from remembering and interpreting complex routing rules
associated with next hop selection and at the same time makes re-routing
decisions based on load conditions and health status of NF providers.
In the absence of an alternate route, the Service Communication Proxy
rejects requests destined to a failed or degraded NF, thereby acting as a
circuit breaker. This prevents valuable resources at the user NFs from being
tied up waiting for responses from providers. The Service Communication Proxy
can also perform Retries on behalf of the service user there by relieving the
service user from this burden and leaving it to focus on the application.
3gpp-Sbi-Message-Priority
header is defined to carry the message priority of 5G messages. The SCP
includes or modifies the header based on the configuration parameters. See
Configuring MessagePriority Options.
Circuit Breaking
and Outlier Detection
Service Communication Proxy tracks the status of
each individual endpoint of the producer NFs/NF Services. Upstream producer
EndPoints that continually return 5xx errors for service requests are ejected
from the routing pool for a pre-defined period of time. Outlier detection is a
form of passive health checking of producer NFs. Outlier detection is per
endpoint (of producer NF instance) and triggers when SCP receives consecutively
5xx error response and exceeds the configurable number of consecutive 5XX
errors.
Overload
Control
The overload control protects the pod (server) from overload with
respect to various system resources such as memory, CPU, or file descriptors
due to several client connections or requests.
The SCP worker and controller supports overload control based on the
usage of below listed resources:
Memory
CPU
File descriptors
The SCP worker and controller considers itself to be overloaded if the
usage associated with memory, CPU or File descriptors exceeds the operator
configured threshold values.
In the event of overload, the SCP performs the below configured
actions
Refuse new connections
Respond to new ingress
requests with a configurable Error ( status) and code (Default Error code –
503).
The following are available in observability.
Metrics
Metrics services requests are proxied through the Service
Communication Proxy, the Service Proxy Controller can collect Metrics and KPIs
related to message processing. With this information, the Service Communication
Proxy is in a unique position to provide a view of health status the network at
a given time. See
Metrics, KPIs, and Traces.
Tracing
Compliant with open API tracing
Logging
Compliant with ELK stack.
