Abstract: A packet processing method includes a first network device receiving a first Bit Index Explicit Replication (BIER) packet including a first BIER header. When the first BIER packet is a packet sent to a second network device, and in response to determining that the second network device is an edge node device in a BIER communication network and does not support BIER packet forwarding, the first network device determines a target label used for a reverse path forwarding (RPF) check, updates the first BIER packet to obtain a second BIER packet, where the second BIER packet includes the target label but does not include the first BIER header, and sends the second BIER packet to the second network device.

Abstract: Some embodiments provide a method for forwarding data messages between edge nodes that perform stateful processing on flows between a logical network and an external network. At a particular edge node, the method receives a data message belonging to a flow. The edge nodes use a deterministic algorithm to select one of the edge nodes to perform processing for each flow. The method identifies a first edge node to perform processing for the flow in a previous configuration and a second edge node to perform processing for the flow in a new configuration according to the algorithm. When the first and second edge nodes are different, the method uses a probabilistic filter and a stateful connection tracker to determine whether the flow existed prior to a particular time. When the flow did not exist prior to that time, the method selects the second edge node for the received data message.

Abstract: A method and system of a low-latency FPGA framework based on reliable UDP and TCP re-assembly middleware is disclosed. The need for low-latency communication in digital systems has increased drastically. The disclosed FPGA framework enables low-latency communication as a hybrid framework that supports both UDP & TCP communication.

Further, the disclosed system proposes a TCP re-assembly middleware architecture for processing TCP with a lower-latency, wherein the TCP re-assembly middleware is an independent middleware that is a modular and a plug-play independent middleware.

Abstract: A network device receives an attribute identifying paths associated with an open shortest path first (OSPF) domain of a network and an intermediate system to intermediate system (ISIS) domain of the network, and provides the attribute to other network devices of the network. The network device receives traffic destined for one of the other network devices of the network, and determines that a primary path is unavailable for routing the traffic to the one of the other network devices. The network device selects a secondary path from the paths identified by the attribute. The secondary path is selected based on determining that the primary path is unavailable, and the secondary path is associated with the OSPF domain or the ISIS domain of the network. The network device provides the traffic to the one of the other network devices via the secondary path.

Abstract: A software defined networking (SDN) controller or routers in a network determine unicast paths from an ingress router to egress routers from the network based on quality-of-service (QoS) metrics for links between routers of the network. A subset of the unicast paths is associated with a multicast flow based on one or more QoS criteria for the multicast flow. A router pushes a label stack onto a packet of the multicast flow. The label stack includes labels that identify the subset of the unicast paths. The packet including the label stack is multicast through the network to the egress routers. Routers that receive the multicast packet selectively modify the label stack in the packet based on the labels that identify the subset of the unicast paths. The routers selectively forward the packet based on the labels.

Abstract: A multi-tenant computing system provides services to a number of different tenant organizations. To address the problem of failure of portions of the system, the hardware infrastructure of the system is located at a number of different geographical locations. The various tenants are assigned to one of a set of “cells,” each cell corresponding to one of the geographical locations. Additionally, each cell has another one of the cells assigned to it as a backup cell, and the data of each cell is replicated within its assigned backup cell. At system run time, if a failure is detected within one of the cells, the network redirection is used within the multi-tenant system to reflect that the backup cell for the failing cell is now handling requests for the failing cell. Upon determination that the failing cell has been repaired and is now again correctly functioning, the network redirection is no longer employed, such that the (formerly) failing cell again handles its own requests.

The technical problem of generating connection recommendations for a user at registration time in a privacy-safe manner is addressed by a recommendation methodology that obscures the connection source and the connection distance of the recommended profiles.

Abstract: Approaches, techniques, and mechanisms are disclosed for maintaining efficient representations of prefix tables for utilization by network switches and other devices. In an embodiment, the performance of a network device is greatly enhanced using a working representation of a prefix table that includes multiple stages of prefix entries. Higher-stage prefixes are stored in slotted pools. Mapping logic, such as a hash function, determines the slots in which a given higher-stage prefix may be stored. When trying to find a longest-matching higher-stage prefix for an input key, only the slots that map to that input key need be read. Higher-stage prefixes may further point to arrays of lower-stage prefixes. Hence, once a longest-matching higher-stage prefix is found for an input key, the longest prefix match in the table may be found simply by comparing the input key to lower-stage prefixes in the array that the longest-matching higher-stage prefix points to.

Abstract: A system and method for FIB aggregation. FIB Aggregation with Quick Selections (FAQS) is a FIB aggregation algorithm that leverages compact data structures and three unique optimization techniques to quickly and incrementally select next hops when handling route updates. As a result, FAQS can run up to 2.53 and 1.75 times faster for IPv4 and IPv6, respectively, than the optimal FIB aggregation algorithm while achieving a near-optimal aggregation ratio. Meanwhile, it consumes much less memory and generates much smaller number of FIB changes when carrying out frequent updates. The performance enhancement of the new algorithm addresses many concerns from ISPs regarding performance issues, and enhances the probability to push FIB aggregation techniques further to the level of production adoption by the industry.

Abstract: Disclosed is a method and apparatus for performing steps to cause encoded information to be stored at a client device during a first network session between a server and the client device. To cause encoded information to be stored at a client device, the server first determines a set of network resource requests that encode the information.

The server then causes the client device to initiate the network resource requests. The server may cause this initiation by, for example, redirecting the client device to the network resources. The client device initiating the network resource requests causes data representative of the network resource requests to be stored at the client device.
