Each of a first group of gateway nodes of a communications network operates as a primary gateway identified by a respective unique gateway identification number (GWID), and each of a second group of gateway nodes operates as a backup gateway. Each gateway node has an assigned backup priority level with respect to each GWID. The gateway nodes are interconnected via a common local network. In the event that a primary gateway node becomes non-operational, the backup gateway that is assigned the highest priority level with respect to the GWID of the non-operational primary gateway assumes operation as the primary gateway identified by that GWID. Upon restoration of the non-operational gateway node, the gateway node operates as a backup gateway in place of the gateway node that assumed its operation as the primary gateway. A gateway node operates as a primary gateway for only one respective GWID at a time.

Gateway redundancy protocol for communications networks

Approaches for managing characteristics for inbound data communications between a first network site and a remote network site of a WAN are provided. The inbound communications are received by the first network site via a series of links of the WAN. Protocol overhead factors are determined based on overhead associated with network protocols applied to the data communications over the links. Link throughput limits are determined for the inbound data communications, wherein the throughput limits are determined based on the protocol overhead factors. The throughput limits are transmitted to the second network site for transmission of the inbound data communications from the second network site. The inbound data communications are received by a first device of the first network site via the first link, wherein the first link is between the first device and a second device serving as an exit point from a public portion of the WAN.

System and method for providing quality of service over dedicated local loop networks

An apparatus, method, and system for quality of service over dedicated local loop networks is provided. Information regarding uplink and downlink speeds, and information regarding WAN interface protocol and encapsulation mode, is received from a network device. A link throughput limit is calculated based on the uplink speed of the network device, and a link throughput limit is set based on the calculated uplink throughput limit. An uplink network protocol overhead of the network device is calculated based on the WAN interface protocol and encapsulation mode of the uplink device and is factored in upstream available bandwidth calculations. Communication data size(s) are set based on the calculated uplink network protocol overhead. The downlink throughput limit is set to match the downlink speed based on the downlink speed and WAN network protocol overhead. The WAN network protocol overhead is factored in the downstream available bandwidth calculations and communication data sizes.
