Embodiment 1

[0032] As shown in Fig. 2, the present invention is the original main line between router and switch, adds a backup line, and installs a bridging mode network acceleration device FB2 (standby) in this backup line, and the bridging network in the backup line The configuration of the acceleration device and the bridging network acceleration device of the main line can be different. Since the bridge mode network acceleration device FB1 (activation) and the bridge mode network acceleration device FB2 (standby) in the standby line perform hot backup monitoring, when the two paths are normal, the network interface of the bridge network acceleration device FB1 (activation) allows The packet passes, except for the hot backup monitoring communication packet between the two devices, the network interface of the bridging network acceleration device FB2 (standby) blocks other packets to ensure that the backup line from point C to point D is unreachable, and that there is no communication b...

Embodiment 2

[0048] Add a connection line E between the bridged network acceleration devices FB1 and FB2 that realize dual-machine hot backup, and the active state device sends a status briefing to the standby state device on this connection line E, as shown in Figure 6, the bridged network acceleration When the device FB1 is activated, it will check the network status in two directions:

[0049] 1. Send an ICMP request to the uplink router or uplink switch or other IP devices on the uplink or external network websites or other IP devices on the external network on the network port of the uplink remote line A to determine the status of the uplink.

[0050] 1.1 If the ICMP response from the upstream device is received within the specified time, FB1 remains active.

[0051] 1.2 If there is no ICMP response from the uplink device within the specified time, FB1 determines that there is a fault between the uplink remote line A and the uplink device (as shown in Figure 7), and immediately connec...

Embodiment 3

[0069] When the upstream router or upstream switch and the downstream router or downstream switch start 802.3ad (LACP) multi-link aggregation (Figure 10), and connect to the bridging network acceleration device, there is a connection line E between FB1 and FB2, FB1 and FB2 Send a status briefing on the E line, which is also a data backup line. The two physical devices FB1 and FB2 will form a virtual bridging network acceleration device, and the virtual bridging network acceleration device will start the 802.3ad (LACP) multi-link aggregation protocol and The uplink device and the downlink device are connected (Fig. 11), and traffic can be accelerated through FB1 or FB2 at the same time (Fig. 12).

[0070] 1. When the uplink A fails:

[0071] 1.1 FB1 detects the failure of the uplink A network port, FB1 sends an uplink path failure report to FB2, and changes the traffic channel of the uplink A network port to the E line. When FB2 receives the uplink path failure report of FB1, t...

Abstract

The invention provides a multimachine back-up method of a bridge network accelerating device and a system thereof, wherein a plurality of bridge network accelerating devices accelerate the network flow at the same time. The method comprises: the plurality of bridge network accelerating devices detects the net mouth of an uplink network device and a downlink network device at the fixed period; when one of the plurality of bridge network accelerating devices goes wrong, or the net mouth of the uplink network device and the downlink network device goes wrong, the bridge network accelerating device is stopped, and the network flow is accelerated through the residue network accelerating device.

Description

technical field [0001] The invention relates to the field of network hot backup, in particular to multi-computer hot backup of bridging network acceleration devices. Background technique [0002] Existing network acceleration devices or proxy devices operate on a three-layer network (Explicit mode / Transparent mode / IPaddress Layer / Layer 3), and there are few network acceleration devices that support bridge mode (Bridged mode / Mac address Layer / Layer 2) . As shown in Figure 1, the existing bridged mode (Bridged Mode) network acceleration devices are generally located between routers and switches, and in the network structure, from routers to switches to users, they are all in the same broadcast domain, that is, they are all in the same broadcast domain. within the same IP network segment. For example, when the bridge mode network acceleration device fails in the network path, it will cause a single point of failure, resulting in network truncation, and users cannot connect to...
