Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing IPoE, and a home gateway.
Background
A Bandwidth Remote Access Server (BRAS) is a novel Access gateway for bandwidth network application, which is located at the edge layer of a backbone network and can complete data Access of an IP/ATM (asynchronous transfer mode) network of user bandwidth, thereby realizing bandwidth internet Access of commercial buildings and residential households, IP VPN (virtual private network) service based on IPSec (internet security protocol), Intranet (Intranet) construction of enterprises, and application of supporting ISP (internet service provider) to wholesale services to users.
IPoE (IP over Ethernet, internet protocol based on Ethernet) dial-up service is a major service supported by the existing BRAS. Currently, the IPoE service has the following problems in practical use:
the home gateway RGW of the user starts normal service access after IPoE access is successful, and at this time, if a link between the RGW and the BRAS fails, the BRAS deletes the IPoE list item of the user and recovers the IP address allocated to the user after detecting the link failure.
When the link failure is repaired, the service access is still performed by the user RGW using the original IP address because the lease of the IP address of the user RGW is not expired (the lease is generally long, for example, one week), which may result in an access failure. Unless the user restarts the home gateway RGW, service access will not be possible and the user experience is poor.
In other words, after the link between the RGW and the BRAS fails and is repaired, the user RGW still uses the original IP address to perform service access because the lease of the IP address of the user RGW is not expired, and at this time, the BRAS deletes the IPoE entry of the user, thereby resulting in access failure. Unless the user restarts the home gateway RGW, service access will not be possible and the user experience is poor.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for processing an internet protocol IPoE based on an ethernet, which is applied to a home gateway, and includes:
and step 11, the home gateway periodically sends an echo request message to the IPoE server through a link between the home gateway and the IPoE server.
In this step, the home gateway detects whether a link has failed and whether the failure is recovered through an echo request message. Wherein, the IPoE server is a BRAS server or a DHCP server; and the home gateway is an IPoE client.
And 12, releasing the IP address currently allocated to the home gateway under the condition that the link is detected to be in failure.
In this step, the home gateway RGW directly returns to the initialization state after detecting the link failure, thereby locally releasing the IP address applied by itself.
And step 13, sending a Dynamic Host Configuration Protocol (DHCP) discovery request under the condition that the fault recovery of the link is detected, and applying for an IP address to the IPoE server through the DHCP discovery request.
In this step, after the home gateway detects the failure recovery, it initiates a DHCP discovery process to reapply a new IP address. The new IP address is used for information interaction between the home gateway and the IPoE server.
As an alternative embodiment, the method further comprises:
determining that the link failure is detected in the case that no echo response (echo) message sent by the IPoE server is received in N consecutive echo request (echo) messages sent by the home gateway;
wherein N is an integer greater than or equal to 2.
For example, since the home gateway does not receive the echo response message after continuously transmitting the echo request message 3 times, the home gateway determines that the link is failed at this time.
Further, the method further comprises:
determining that failure recovery of the link is detected upon receiving an echo response message sent by the IPoE server.
It should be noted that, no matter whether the link fails, the home gateway sends an echo request message according to the current probing period, and the home gateway determines that the link fails to recover when receiving an echo response message.
In order to reduce the processing pressure of two communication parties (a home gateway and an IPoE server) on echo messages (the echo messages comprise echo request messages and echo response messages), the detection period of the home gateway in the embodiment of the invention can be dynamically adjusted, namely the echo request messages carry the detection period; it should be noted that the echo request message is a DHCP message, and an M-bit reserved bit in a DHCP message header is used to indicate the probe period; m is an integer greater than or equal to 1. For example, M equals 8, and 8 bits reserved in the DHCP message header identify the probe period for flexibly adjusting the probe period and alleviating the pressure on the IPoE server. For example, the detection period is set to be short after the outgoing link fails, and the detection period is long after the failure is recovered, so that the pressure of the server can be greatly reduced.
The cycle length of the sounding cycle carried by the echo request message sent before the link fails is greater than the cycle length of the sounding cycle carried by the echo request message sent during the link failure.
The cycle length of the detection cycle carried by the echo request message sent after the failure recovery of the link is greater than the cycle length of the detection cycle carried by the echo request message sent during the failure of the link.
In other words, under the condition that the link state is normal, the sounding period carried by the echo request message sent by the home gateway is a long period (for example, T1 period); under the condition of link failure, the sounding period carried by the echo request message sent by the home gateway is a short period (for example, T2 period); when the link state is changed from normal to failure, the home gateway sets the detection period to a short period (T2 period) so as to be discovered in time after the link failure is recovered; after the home gateway detects that the link failure is recovered, the detection period is set to be a long period (T1 period), so that when the link state is normal, the processing pressure of the echo messages of both communication parties is reduced.
It should be noted that, in the embodiment of the present invention, the echo request message and the echo response message are DHCP messages, and different messages are identified by different types of DHCP; for example, Type 10 represents an echo request message Type; type 11 represents an echo response message Type.
As an optional embodiment, if the IPoE server does not receive the echo request message sent by the home gateway within the preset time length, it is determined that a link between the home gateway and the IPoE server fails (i.e., it is considered that the home gateway has lost connection); and deleting the IPoE session table entry of the home gateway, recovering the IP address allocated to the home gateway, and taking the user corresponding to the home gateway offline through an AAA (authentication, authorization and accounting) server.
After the failure of the link is recovered, the IPoE server receives a Dynamic Host Configuration Protocol (DHCP) discovery request sent by the home gateway, and allocates an IP address to the home gateway according to the DHCP discovery request.
As shown in fig. 2, a flow of the processing method of IPoE provided by the embodiment of the present invention is as follows:
the home gateway uses IPoE mode to successfully authenticate and charge, and allocates IP address, then external service access is normally carried out between the home gateway and the network. Under the condition that the link state is normal, the home gateway sends an echo request message (carrying a detection period of 3min), the home gateway continuously sends the echo request message for 3 times and does not receive an echo response message, the home gateway determines that the link fails at the moment, and the home gateway returns to the initialization state, so that the IP address applied by the home gateway is locally released.
The IPoE server does not receive an echo request message sent by the home gateway within a preset time length, determines that a link between the home gateway and the IPoE server fails, deletes an IPoE session table entry of the home gateway and recovers an IP address allocated to the home gateway, and a user corresponding to the home gateway is offline through the AAA server.
The home gateway continues to send an echo request message (the carried detection period is 20s), and after the link failure is recovered, the home gateway receives an echo response message, and then judges that the link failure is recovered. The home gateway can continue the echo request message (the carried detection period is 3min), successfully authenticate and charge through the DHCP discovery process, and allocate the IP address. And subsequently, external service access is carried out according to the newly allocated IP address.
In summary, the embodiment of the present invention increases the active detection capability of the home gateway, so that the home gateway releases the current IP address when detecting that the link has a failure, and re-applies for a new IP address through the DHCP discovery request when detecting that the link has a failure and recovers, thereby realizing automatic online without restarting the device after the failure recovery, and reducing the operation and maintenance cost while greatly improving the physical examination of the user.
