Novel tools and techniques in a telecommunication network are provided for implementing a data link layer control plane that may comply with the Ethernet standard and with sub-millisecond transmission control capabilities across multiple dis-similar technologies and bandwidth links. The framework provides a dynamic modular traffic control function insertion, removal, mapping function by having interpreter functions in the protocol agents that can map states and commands to sub-service chain functions that are configured per path and quality of service (QoS) flows. The control protocol provides high levels of resiliency and reliability by having a replicating function that transmits the same control protocol frames across multiple links simultaneously. The agents are multi-chassis capable and support hitless service impacts for administrative changes. Control plane messages may be encoded as a data plane frame and be transmitted at a high rate using the data plane.

Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

Systems and methods include a method for securing an Internet protocol (IP) Multimedia Subsystem (IMS)-based voice over IP (VoIP) network with multiple virtual private networks (VPNs). A call sent by a first user endpoint (UE) to a second UE is received by a SBC. The SBC provides security for an IMS-based VoIP network and controls traffic between a first VPN connecting IMS core servers, a second VPN connecting IP phones, and a third VPN connecting non-IP-phone devices. The call originates from either of the second VPN connecting the IP phones or from the third VPN connecting the non-IP-phone devices. A signaling for the call is encrypted and routed by the SBC to the second UE. A media flow for the call is encrypted and routed by the SBC through the third VPN before routing the call to the second UE.

There is provided a software-defined networking, SDN, architecture network, comprising a first network node (100) and a second network node (300), the first network node being configured to transmit data packets comprising: user data packets belonging to two or more user data packet flows, the user data packets of each user data packet flow comprising user data plane information; and control data packets each comprising OSI layer 7, L7, information for controlling the processing by the second node of the user data packets of a respective one of the user data packet flows. The SDN architecture network further comprises an SDN architecture forwarding element configured to forward user data packets received from the first node towards the second node using forwarding information that links a forwarding address to information in an IP 5-tuple of a data packet. The forwarding element is further configured to selectively forward a control data packet received from the first node towards the second node by: receiving and storing L7 information and the forwarding information; performing deep-packet inspection of the received control data packet to extract the L7 information therein, and selecting the received control data packet for forwarding towards the second node when the received control data packet comprises L7 information matching the stored L7 information; determining information in the IP 5-tuple of the received control data packet; and, where the received control data packet has been selected for forwarding, forwarding said control data packet towards the second node using the forwarding information and the information in the IP 5-tuple of the control data packet. The SDN architecture network also includes a controller (620) configured to transmit the L7 information and the forwarding information to the forwarding element (610).

The disclosure relates to a message distribution system configured to provide traffic messages received by at least one base station of a telecommunications network to at least one traffic control system capable of controlling traffic infrastructure. The message distribution system comprises a detection module and a routing module. The detection module is configured to detect traffic messages from user devices in a radio coverage area of the at least one base station. The routing module is configured to access association information associating at least one routing address of the at least one traffic control system with the radio coverage area of the at least one base station and to route the detected traffic messages to the at least one routing address associated with the radio coverage area of the at least one base station receiving the traffic messages from the user devices.

A Fibre Channel Forwarder (FCF) routing system includes an FCF device that is coupled to a FC networking device through a first FCF device port, an initiator device through a second FCF device port; and a target device through a third FCF device port. The FCF device receives, at the second FCF device port, traffic that originates from the first initiator device and that is addressed to the first target device. The FCF device determines, using an FCF device association table that identifies zones provided by the FC networking device, that the target device is associated with the initiator device. The FCF device then routes, in response to determining the target device is associated with the initiator device, the traffic through the third FCF device port to the target device without forwarding the traffic through the first FCF device port to the FC networking device.

This disclosure provides a data sending method and apparatus, and a device, and pertains to the field of communications technologies. An example method includes: receiving an uplink data packet sent by UE; if a signaling message is carried in the uplink data packet, separating the signaling message from the uplink data packet, where the signaling message is used to request to establish a PDU session or request to activate an established PDU session; forwarding the signaling message to a control plane device; and before an available PDU session exists, forwarding, based on a data forwarding message carried in the uplink data packet sent by the UE, data in the uplink data packet sent by the UE.

Remote management of an information handling system is based on a dynamic port assignment. A port number in the TCP/IP protocol identifies packets of data reserved for the remote management of peripheral devices connected to, or communicating with, the information handling system. When a network interface card receives the packets of data, the network interface card compares headers of the packets of data to the port number reserved for the remote management. The network interface card identifies and routes the packets of data having the headers specifying the port number for the remote management of the information handling system.

Embodiments of the present invention disclose a signaling packet processing method and an entity. The method may include: obtaining, by a gateway user plane entity, processing information of a target signaling packet; and receiving, by the gateway user plane entity, the target signaling packet, and processing the target signaling packet based on the processing information. Network costs can be reduced in the embodiments of the present invention.

Methods, systems, and computer readable media for supporting multi-homed (MH) connections are disclosed. According to one method, the method comprises: determining that an MH connection is enabled; identifying a local initiate port associated with the MH connection; using the local initiate port to configure connection rules to allow traffic associated with a plurality of paths associated with the MH connection; and using the connection rules to process traffic received over the MH connection.
