In some aspects, the disclosure is directed to methods and systems for encapsulating intra-device protocols, such as CXL and/or PCIe packets, into inter-device protocols, such as IP packets, allowing resources across one or more networks to be shared. For example, CXL and/or PCIe address to IP address lookup tables may be used to determine destination IP addresses or source IP addresses such that CXL and/or PCIe packets may be sent across various networks. Layer 3 forwarding enables communication between large distributed systems while utilizing existing network infrastructure.
