SR-enabled network nodes capable of replicating and recombining data packets in a manner that enables reliable, low-latency communications. In an example embodiment, a replicator node transmits to a combinator node multiple copies of a payload over different respective network paths, with the SR headers of the corresponding packets each having a replication segment identifier or a respective SID stack that includes the replication segment identifier. The combinator node delivers/forwards to the corresponding application/destination only the first-to-arrive payload copy and discards any subsequent payload copies based on the replication segment identifier. Some embodiments may beneficially reduce latency and packet loss concurrently and consistently. For example, packet loss may be reduced due to the transmission of multiple copies of the same payload over multiple network paths. Effective latency may be reduced due to the selection of the first-to-arrive payload copy for delivery/forwarding.

Aspects related to application based routing of data packets is described. In an example, a method for enabling application based routing of data packets includes retrieving, by a client device, a prioritized list of client application parameters to process data packets from at least one client application. The prioritized list is generated based on application support capabilities of the client device. The method includes transmitting client parameters to a network server to create at least one multi-path proxy (MPP) instance. Each MPP instance of the at least one MPP instance is configured to aggregate and route data packets to a pre-defined core network link. The method further includes receiving identification information pertaining to the at least one MPP instance from the network server. Based on the identification information, the prioritized list is assigned to the at least one MPP instance to process data packets from at least one client application.

Aspects relating to data transmission are described herein. In an implementation, in a method for data transmission, a tunneling protocol header is appended to a payload to obtain an encapsulated data packet, and at least one field is modified in the tunneling protocol header to indicate at least one of an access network () and a core network () for transmitting the encapsulated data packet, and the access network () and the core network () belong to different communication networks (). Further, based on the tunneling protocol header, the encapsulated data packet is delivered to a routing unit for transmission.

Various exemplary embodiments relate to a method for determining whether to admit a query in a network, the method including determining a load for a network element type based on an adaptive history for that network element type; determining a cost of admitting the query based on the relative load that the query generates accounting for the amount of traffic the network element has admitted in the past; decreasing a total cost of all queries that can be budgeted during a subsequent interval when the change in load is within a specified range; increasing the total cost of all queries that can be budgeted during a subsequent interval when the change in load is below a threshold; and adding the query to a data structure which keeps track of potentially admittable queries.

A base station provides, a first number of probe packets to an access point for transmission to a user equipment over an access network path. The base station receives information indicating a bandwidth of the access network path estimated by the user equipment. The base station determines which of the base station or the access point to use for communication with the user equipment based on the bandwidth. The user equipment receives a second number of packets over an air interface and determines inter-arrival packet delays for the second number of probe packets. The user equipment estimates the bandwidth of the air interface based on the inter-arrival packet delays, the first number, and a time interval for transmission of the first number of probe packets. The user equipment transmits information indicating the bandwidth.

A method includes receiving at least one current network condition factor (NCF), each current NCF indicating a level of congestion of a corresponding network. The method determines that there is an autonomous report to be transmitted and in response determines a policy entry of a policy used for autonomous reporting based on matching values of one or more input parameters related to the autonomous report to values of one or more input parameters of the policy entry. A reference NCF for a first network is determined from the corresponding policy entry. The method then determines whether to request to transmit the autonomous report on the first network based on a comparison of the reference NCF for the first network and the current NCF of the first network.
