A communication apparatus connected to a virtual apparatus having an address dispensing function via an access network is provided, wherein the communication apparatus includes a communication confirmation unit configured to perform a communication confirmation between the virtual apparatus and the communication apparatus; and an address dispensing unit configured to dispense an address to a user terminal under control of the communication apparatus when communication between the virtual apparatus and the communication apparatus is not able to be confirmed by the communication confirmation unit, and the address dispensing unit causes the user terminal to forcibly release the address when the communication between the virtual apparatus and the communication apparatus is able to be confirmed by the communication confirmation unit.

According to some embodiments, a method performed by a first software defined wide area network (SD-WAN) edge router communicably coupled to a public network comprises: receiving a transport location (TLOC)-extension configuration for a known interface of the first edge router; detecting a second edge router attempting to connect to the known interface of the first edge router; and transmitting, to the second edge router, configuration information for the second edge router so that the second edge router is able to communicate with the public network through a TLOC-extension with the first edge router. In some embodiments, the second edge router receives device configuration information (e.g., PnP, ZTP, etc.) from the public network via the TLOC-extension.

In an FTTDP optical fibre network, Distribution point units are reverse powered by customer premises equipment and therefore liable to power failure. When the distribution point unit loses power it is unavailable to respond to requests for performance or metric data. A persistent manager agent functions as a proxy for the distribution point unit, gathering metric and performance data from the distribution point unit using at least one EOC channel and handling requests for performance and metric data issued from other network devices. The persistent manager can also schedule downloads of firmware and configuration data to the distribution point unit.

Methods, systems, and computer readable media for network function (NF) service instance wide egress rate limiting include a process performed at a service communication proxy (SCP) and at a rate limiting policer. The process includes receiving service requests from consumer NFs and forwarding the service requests to SCP worker instances. The process further includes, at the SCP worker instances, requesting, from the rate limiting policer, which is separate from the SCP worker instances, producer NF service instance capacity for handling the service requests. The process includes, at the rate limiting policer, performing producer NF service instance wide egress rate limiting between the SCP worker instances and producer NF instances by granting or denying requests for producer NF service instance capacity from the SCP worker instances such that combined egress traffic from the SCP worker instances does not exceed rate capacities of the producer NF service instances.

A Device Abstraction Proxy (DAP) interface receives a request for operational data relating to broadband access line services provided to a plurality of broadband access terminals in a network by multiple providers. The DAP interface receives, in response to the request, operational data for multiple DSL lines coupled to the multiple broadband access terminals. The DAP then identifies multiple broadband access lines as belonging to a common neighborhood of broadband access lines, each of the multiple DSL lines respectively associated with multiple broadband access terminals being provided the broadband access services by different providers. Embodiments correlate a condition and/or a performance of one of the multiple broadband access lines identified as belonging to the common neighborhood with a condition and/or performance of another one of the multiple broadband access lines identified as belonging to the common neighborhood.

Present disclosure relates to system and method for providing SIP trunk service to at least one telephone system by an application server over a network, comprising establishing a connection between at least one telephone system and a first network entity via a first access node, and availing at least one SIP trunk service. Next, the at least one telephone system dynamically checks connectivity with the first network entity. The at least one telephone system establishes a connection with a second network entity via a second access node, in an event the connectivity with the first network entity fails and transmits a signal request to the application server. The application server processes the signal request and provides the at least one SIP trunk service to the at least one telephone system.

The present technology provides a system, method, and computer-readable medium directed to dynamic implementation and management of multi-provider internet access featuring multiple access points across a multi-site overlay network fabric. An aspect of the technology is directed to the implementation of a common fabric-wide Virtual Network (VN) with a unique Internet Instance Identifier (Internet IID) that is dedicated to internet access traffic. Default access routes from multiple service providers (SP) are leaked into the VN with the Internet IID at exit points of the fabric using local Extranet policies. Internet-bound traffic generated from any point within the overlay fabric network is then redirected into the Internet IID, using remote Extranet policies. Internet-bound traffic, once in the Internet IID, follows the SP default access route(s) towards the exit points where SP specific access policies may be applied to the traffic which is then forwarded to the corresponding SP network.

A Device Abstraction Proxy (DAP) interface receives a request for operational data relating to broadband access line services provided to a plurality of broadband access terminals in a network by two or more providers. The DAP interface receives, in response to the request, the operational data, including operational data for a plurality of DSL lines coupled to the plurality of broadband access terminals. The DAP then identifies at least two of the plurality of broadband access lines as belonging to a common neighborhood of broadband access lines, each of the at least two of the plurality of DSL lines respectively associated with at least two of the plurality of broadband access terminals being provided the broadband access services by different providers. Embodiments correlate a condition and/or a performance of one of the at least two broadband access lines identified as belonging to the common neighborhood with a condition and/or performance of another one of the at least two broadband access lines identified as belonging to the common neighborhood.

A network device including an Ethernet transmission interface and a processing unit is provided. The Ethernet transmission interface is provided with at least one Ethernet transmission port. The processing unit is coupled to the Ethernet transmission interface and is configured to: in order to detect whether a packet looping exists, send out a dynamic host configuration protocol (DHCP) discover message through a linked Ethernet transmission port in response to linking one of the at least one Ethernet transmission port to a network and determine whether a DHCP offer message is received; determine whether to prohibit data transmission of the linked Ethernet transmission port according to whether the DHCP discover message returned through the packet looping is detected; classify the linked Ethernet transmission port as an uplink transmission port or a downlink transmission port according to whether the DHCP offer message is received.
