The present disclosure discloses a method and network device for control plane protection for various tables using storm prevention entries. Specifically, the disclosed system receives a first packet, and creates an inactive entry in a table. The system then forwards the first packet from a first processor to a second processor for processing. Also, the system associates the inactive entry with a timestamp indicating when the first packet is forwarded to the second processor, and determines a configured interval (CI) associated with the table. Further, the system compares a difference between a current timestamp and the timestamp associated with the inactive entry against the CI upon receiving a second packet. If the difference is longer than the CI, the system associates the inactive entry with the current timestamp, and forwards the second packet to the second processor for processing. Otherwise, the system discards the second packet.

A method includes determining a delivery performance of a data flow being transmitted from a first network equipment to a second network equipment over a network; determining whether the network is congested based on the determined delivery performance of the data flow being transmitted to the second network equipment; and pacing delivery of the data flow to the second network equipment by reducing a rate at which the data flow is delivered to the second network equipment when the network is determined to be congested.

A device may receive an indication to establish a communication session between a first device and a second device for a file transfer. The device may receive, from the second device, metadata. The metadata may be used to identify files of a set of files. The device may identify the files for transfer from the second device to the first device based on the metadata. The device may cause multiple communication sessions to be established between the first device and the second device. The multiple connections may be used to transfer the files from the second device to the first device. The device may receive, from the second device, the files. The files may be received via the multiple communication sessions.

Techniques for propagating routing awareness for autonomous networks are described. In at least some embodiments, routing awareness refers to attributes of autonomous networks that route communication sessions between different endpoints. According to various embodiments, routing awareness indicates whether a particular autonomous network supports a protocol for propagating routing awareness among different autonomous networks. Routing awareness may also include performance attributes of autonomous networks. Such routing awareness enables entities involved in routing communication sessions to make informed decisions regarding routing and handling of communication sessions.

Some embodiments provide a method for implementing a logical router in a network. The method receives a definition of a logical router for implementation on a set of network elements. The method defines several routing components for the logical router. Each of the defined routing components includes a separate set of routes and separate set of logical interfaces. The method implements the several routing components in the network. In some embodiments, the several routing components include one distributed routing component and several centralized routing components.

A flow-based network switching system includes a memory having a flow table and a packet processor coupled to the memory. The packet processor includes a user-programmable flow-based rule storage that includes a plurality of flow-based rules. A flow-based handler and session manager in the packet processor is operable to retrieve application layer metadata from a first packet received over a network, determine a first flow session associated with the first packet using the application layer metadata from the first packet and the flow table, and retrieve at least one of the plurality of flow-based rules from the programmable flow-based rule storage using the application layer metadata from the first packet. A flow-based rule processing engine in the packet processor is operable to apply the at least one flow-based rule to the first packet. Packets with applied flow-based rules are forwarded through the network.

Disclosed are a method for selecting a session and a service continuity mode in a wireless communication system and a device therefor. Specifically, a method for selecting a session-and-service continuity (SSC) mode associated with a protocol data unit (PDU) session by a user equipment (UE) in a wireless communication system supporting a plurality of SSC modes may comprise the steps of: receiving a data transmission request from an application; checking whether a first PDU session can support an SSC mode associated with the application; and when the first PDU session can support the SSC mode associated with the application, transmitting data of the application to a network by using the first PDU session without sending a request for establishment of a new second PDU session to the network, although an SSC mode of the first PDU session does not match the SSC mode associated with the application.

A communication method is provided, which is implemented by a routing device in an information-centered communication network. The method includes the following steps to process a request relative to a data segment from a given stream, the request being routed on a link of the routing device: checking that an input bit rate for said link is higher than a threshold, the input bit rate for the link corresponding to that which is necessary for the device to receive, by using the link, a set of data segments corresponding to pending requests; and timing the request to be routed. The threshold may correspond to the bit rate available on this link at the device input, or the input bit rate may be determined for pending requests related to data segments from the given stream, and the threshold may correspond to a fair bit rate, for example.

The technology disclosed enables understanding the user experience of accessing a web page under high loads. A testing system generates a simulated load by retrieving and loading a single web object. A performance snapshot is taken of accessing an entire web page from the server under load. The performance snapshot may be performed by emulating a browser accessing a web page's URL, the web page comprising multiple objects that are independently retrieved and loaded. The simulated load is configured with a number of users per region of the world where the user load will originate, and a single object from the web page to retrieve. Performance data such as response time for the single object retrieved, number of hits per second, number of timeouts per sec, and errors per second may be recorded and reported. An optimal number of users may be determined to achieve a target user experience goal.
