“…We compare the proposed scheme, RG‐MAA, to the following four schemes: (1) SWSC that allocates one gNB and one CN‐path, (2) MWSC that allocates several gNBs less than or equal to

m_{AN}

and one CN‐path [8], (3) SWMC that allocate one gNB and several CN‐paths less than or equal to

m_{CN}

[12], and (4) MWMC that allocates

m_{AN}

gNBs and

m_{CN}

CN‐paths. For a fair comparison, all comparison schemes allocate the optimal gNBs and CN‐paths to provide minimum network cost while ensuring the required reliability by considering the path setup time and dynamicity of the reliability of gNBs and CN‐paths.…”

“…A lot of work has recently been done to achieve reliable communication [7][8][9][10][11][12][13][14]. These works can be divided into two categories based on the target environment: (1) works for the wireless network [7][8][9][10][11]; and (2) works for the wired network [12][13][14].…”

“…However, more paths indicate increased network costs (e.g., traffic and control overhead) [7]. To balance the trade-off, several works have been proposed, which can be divided into two categories based on the target networks: works for wireless network [7][8][9][10][11] and works for the wired network [12][13][14]. However, since these studies did not consider the unique characteristics of the mobile network (e.g., path setup time and the dynamicity of the mobile network's reliability), they cannot effectively achieve high communication reliability and/or reduce network costs in the mobile network.…”

The mobile network allows redundant transmission via disjoint paths to support high‐reliability communication (e.g., ultrareliable and low‐latency communications [URLLC]). Although redundant transmission can improve communication reliability, it also increases network costs (e.g., traffic and control overhead). In this study, we propose a reliability‐guaranteed multipath allocation algorithm (RG‐MAA) that allocates appropriate paths by considering the path setup time and dynamicity of the reliability paths. We develop an optimization problem using a constrained Markov decision process (CMDP) to minimize network costs while ensuring the required communication reliability. The evaluation results show that RG‐MAA can reduce network costs by up to 30% compared with the scheme that uses all possible paths while ensuring the required communication reliability.

Ao migrar sofisticados recursos de hardware para componentes de software executados em sistemas de nuvem, as redes 5G proveem grande flexibilidade. No entanto, a softwarização das redes 5G impõe grandes desafios à gerência da rede, especialmente em relação à corretude do sistema em tempo de execução. Neste contexto, se torna essencial que o comportamento do sistema seja facilmente observável. Este trabalho apresenta uma investigação empírica sobre observabilidade em um sistema 5G formado pelas redes de núcleo e de acesso. Resultados mostram que a análise combinada de métricas e logs melhora a observabilidade do sistema e facilita a antecipação de ocorrências de falhas. Nossa investigação demonstra também que, apesar de úteis, as mensagens de logs geradas pelo sistema 5G implantado são pouco estruturadas e pouco inteligíveis.

TLS Performance Evaluation in the Control Plane of a 5G Core Network Slice

3GPP has recommended 5G service providers adopt Transport Layer Security (TLS) to secure communications among different Network Functions (NFs) in 5G core network slice. It is imperative to study the impact of TLS on 5G control plane traffic.Previous research has shown that TLS adds costs to protocols, like Session Independent Protocol (SIP) and The Onion Router (ToR). This study aims to study different TLS cipher suites impact on network performance parameters such as packet size, time, and the number of messages sent in distinct 5G control flows. We emulated a 5G core network slice using an open-source project and measured the overhead on the network parameters while 5G slice components transmit control plane traffic on both cases of TLS and no TLS. We examined the impact of different cipher suites of TLS namely, AES128-GCM-SHA256, AES256-GCM-SHA384, and 3DES-EDE-CBC-SHA with key exchange algorithms of RSA (Public Key Encryption) and Elliptic Curve Diffie Hellman Ephemeral (ECDHE) on the NF registration with Network Repository Function (NRF), UE registration, and PDU session establishment. We extended the analysis to TLS1.2 and TLS1.3 overhead using the same cipher suite (AES128-GCM-SHA256) on the NF registration procedure.
