The invention enables high-availability, high-scale, high security and disaster recovery for API computing, including in terms of capture of data traffic passing through proxies, routing communications between clients and servers, and load balancing and/or forwarding functions. The invention inter alia provides (i) a scalable cluster of proxies configured to route communications between clients and servers, without any single point of failure, (ii) proxy nodes configured for implementing the scalable cluster (iii) efficient methods of configuring the proxy cluster, (iv) natural resiliency of clusters and/or proxy nodes within a cluster, (v) methods for scaling of clusters, (vi) configurability of clusters to span multiple servers, multiple racks and multiple datacenters, thereby ensuring high availability and disaster recovery (vii) switching between proxies or between servers without loss of session.

This application provides a packet transmission method, apparatus, and system, and relates to the field of network technologies. The method is applied to a network architecture including a user terminal, a first forwarding device and a second forwarding device. A tunnel is disposed between the first forwarding device and the second forwarding device. The method includes: The first forwarding device receives packets forwarded by the user terminal in the load balancing mode, where the packets include a keepalive packet, and the first forwarding device is a standby forwarding device corresponding to the user terminal. The first forwarding device forwards the keepalive packet to the second forwarding device through the tunnel, where the second forwarding device is an active forwarding device corresponding to the user terminal.

Novel tools and techniques are provided for implementing routing of network traffic across one or more network nodes or utilization of the one or more network nodes based on one or more demand classifications and/or based on detection of a trigger event associated with the one or more demand classifications. In some embodiment, a computing system might monitor network traffic across one or more network nodes or utilization of the one or more network nodes, the network traffic being routed based on a first demand classification. The computing system might determine whether at least one trigger event associated with a second demand classification has occurred. If so, the computing system might adjust the routing of the network traffic across the one or more network nodes or adjust the utilization of the one or more network nodes, based at least in part on the second demand classification.

Embodiments include methods, by a first radio access network (RAN) node, for load balancing with a second RAN node. Such methods include receiving, from the second RAN node, one or more first indications related to resource aggregation capabilities for a plurality of cells served by the second RAN node. Such methods include determining one or more of the following based on the first indications: overall capacity available for offloading user equipment, UEs, to the plurality of cells; whether resources from the plurality of cells can be aggregated to meet service requirements of one or more UEs served by the first RAN node; and one or more UEs to be handed over to the second RAN node. Other embodiments include complementary methods by a second RAN node, as well as first and second RAN nodes configured to perform such methods.

A communication method and apparatus. A user plane network element perform refined differentiated processing on different data packets to adapt to and meet different user requirements and network conditions. A first user plane network element receives a first data packet, where the first data packet carries first indication information. The first user plane network element processes the first data packet based on the first indication information. The first indication information includes one or more of the following: synchronous transmission indication information, packet discard indication information, data type indication information, charging indication information, statistics indication information, or priority indication information.

A first network device receives an association relationship sent by a second network device, where the association relationship includes an association relationship between a first path and a second path. The first network device generates first routing information between the first network device and a target network device based on the association relationship, where the first routing information is used by the first network device to send a packet to the target network device through the first path, and when a cross-slice condition is met, the first routing information is used by the first network device to send a packet to the target network device through the second path.

Examples described herein relate to a network interface device comprising: circuitry, when operational, to: in response to congestion related to a link, cause transmission of link event information to at least one sender of packets to the link, wherein the link event information is to identify congestion information of at least one link other than the link.

A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.
