A method for configuring a first network node using a first autonomous system (AS) number in at least one session established with another node according to a dynamic routing protocol is described. The method is implemented by the first node and includes receiving a configuration message comprising at least one piece of information that is representative of a second AS number intended to be used by the first node as a replacement for the first number, configuring the first node with the second AS number, identifying at least one second node having at least one session according to the dynamic routing protocol, active with the first node, in which the first node is associated with the first AS number, and sending a control message to the at least one second node requesting the replacement of the first AS number with the second AS number by the at least one second node, such that, after the replacement, the first node is associated with the second AS number in the at least one active session.

Some embodiments provide a method for configuring an edge computing device to implement a logical router belonging to a logical network. The method configures a datapath executing on the edge computing device to use a first routing table associated with the logical router for processing data messages routed to the logical router. The method configures a routing protocol application executing on the edge computing device to (i) use the first routing table for exchanging routes with a network external to the logical network and (ii) use a second routing table for exchanging routes with other edge computing devices that implement the logical router.

A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected. Further, the smart process control switch can implement an address mapping routine to identify “known pairs” of physical and network addresses for each device communicating via a port of the smart process control switch. Thus, even if a new hostile device is able to spoof a known physical address in an attempt to bypass locked ports, the smart process control switch can detect the hostile device by checking the network address of the hostile device against the expected network address for the “known pair.”

One or more embodiments of the invention may relate to a method, and/or non-transitory computer readable medium including instructions, for distributing link state information. In one or more embodiments of the invention, the method includes building a link state database on a plurality of network devices; electing a leader from among the plurality of network devices; computing, by the leader, a flooding topology; encoding, by the leader, the flooding topology to obtain an encoded flooding topology; distributing, by the leader, the encoded flooding topology to other network devices of the plurality of network devices.

A system includes a plurality of communication apparatuses grouped into groups, a delivery apparatus that delivers content to the communication apparatuses that belong to the groups, and a communication control apparatus that performs grouping. The communication control apparatus acquires transmittability of the delivery apparatus, acquires transmittability of the communication apparatuses, and acquires bit rates of the content, and the grouping unit determines total transmittability of the communication apparatuses of each of the groups and a total of the bit rates, and performs grouping such that either higher one of the total transmittability and the total bit rate does not exceed transmittability of the communication apparatuses of a group in a higher hierarchical level.

A system described herein may provide a technique for the seamless failover of devices in a network, such as a wireless telecommunications network. For example, embodiments may identify a particular device, such as a Call Session Control Function (“CSCF”), that has failed or that does not meet particular performance metrics. An Internet Protocol (“IP”) address of the failed device may be assigned to a functioning device of the same type (e.g., another CSCF). The functioning device may be instructed, in accordance with some embodiments, to output routes between itself and other devices or IP addresses, based on which traffic originally intended for the failed device may be routed to the functioning device.

Responsive to receiving the BGP UPDATE message, a route reflector may (1) update a CLUSTER_LIST value and, if needed, an ORIGINATOR_ID value, in a path attribute section in the BGP UPDATE message to generate a revised BGP UPDATE message, and (2) send the revised BGP UPDATE message to a client of the route reflector, regardless of whether or not one of (A) field validity checking of the BGP UPDATE message, (B) Adj-RIBS-In update using the BGP UPDATE message, (C) decision processing for route selection using information in the BGP UPDATE message, or (D) Adj-RIBS-Out update using the BGP UPDATE message, is completed (or perhaps even started). This provides faster route propagation and avoids delays associated with processing BGP UPDATE messages (NLRI with advertisements and withdrawals) at each hop the NLRIs using conventional BGP such as next-hop validation, best path selection, etc.
