Provided are apparatus, method, and device capable of forwarding E2 communication a network. According to embodiments, the apparatus may include: at least one memory storage storing computer-executable instructions; and at least one processor communicatively coupled to the at least one memory storage, wherein the at least one processor may be configured to execute the instructions to: obtain a mapping between a first IP address of an instance of E2 Termination deployed at the Near-RT RIC and at least one second IP address of at least one E2 node associated with the instance of E2 Termination; receive a data from an E2 node; determine whether to directly transmit the data to the instance of E2 Termination based on the mapping.

A communication device that performs packet communication includes a data storage unit that holds a rule of a value-added service policy, a transmission unit that inquires to a translation device that performs address translation about translation information including information before the address translation, a reception unit that receives the translation information from the translation device, and a control unit that determines whether to apply the rule to a packet after the address translation received from the translation device by using the translation information.

Techniques for identifying locations of network devices in a fabric network. The method includes a network controller and/or control plane of a network fabric coupled to an access switch at a software-defined access (SDA) site. At least one mapping is registered at the SDA site and sent with the location data from the access switch to the network controller. The network controller and/or control plane is configured to at least one of to learn, update, and publish location data of a destination address from at least one mapping received from the access switch by the location data being associated with a mapping at the SDA site and destination address. The network controller identifies the location of the destination address from a received request based on associating the destination address with the location learned from the location data of at least one mapping that has been registered at the SDA site.

The disclosure provides an approach for processing inter-network communications. Embodiments include configuring, by a management component of a data center, a first virtual private network (VPN) session between a first endpoint outside of the data center and a first gateway of the data center. Embodiments include configuring, by the management component, a second VPN session between a second endpoint outside of the data center and a second gateway of the data center. Embodiments include programming, by the management component, one or more network address translation (NAT) tables of the data center such that, for the first VPN session and the second VPN session, a single public network address of the data center is exposed to the first endpoint and the second endpoint.

Aspects of the subject disclosure may include, for example, remapping a first address bus into a first remapped address bus by replacing bit lines of the first address bus with attribute bit lines, the first remapped address bus supplying updated address information, connecting the first address remapped bus to an address translation unit (ATU), the ATU configured to translate the updated address information into translated address information supplied to a second address bus, and remapping the second address bus into a second remapped address bus by replacing a portion of the second address bus with the bit lines of the first address bus that were replaced by the attribute bit lines, the second remapped address bus changing the translated address information into updated translated address information.
