Description
Technical Field
The invention relates to the technical field of network communication, in particular to a network interconnection equipment evaluation method based on EOS service.
Background
EOS is a frame mapping method, mainly defining the mapping method of encapsulating Ethernet frame and then mapping it into VC (virtual container) of SDH/SONET, and using the SDH positioned between Ethernet MAC layer and physical layer as data link adaptation layer. Because the technologies of SDH and ethernet are mature and fully standardized, the implementation method of EOS becomes a new core technology of MSTP, and is also the key for implementing intercommunication of MSTP of each manufacturer.
The RFC2544 protocol is an international standard proposed by the RFC organization for evaluating network-connected devices (firewalls, IDS, Switch, etc.). The test under the RFC2544 standard mainly comprises the following steps: throughput, delay, packet loss, back-to-back. The method is characterized in that no external test equipment is needed during testing, and the generation and the check of the test frame are finished through own hardware and software.
At present, the throughput, the packet loss rate, the time delay and the back-to-back of the EOS service are expected to be obtained through a tester. However, in some cases where the test environment and the test tool are incomplete, it is troublesome to know the throughput, the packet loss rate, the time delay, and the back-to-back of the EOS.
Disclosure of Invention
The invention provides an evaluation method of network interconnection equipment based on EOS service, which can solve the technical problem that the EOS service is difficult to evaluate under the conditions of incomplete test environment and test tools.
In order to achieve the purpose, the invention adopts the following technical scheme:
a network interconnection equipment evaluation method based on EOS service comprises the following steps:
comprises the following steps:
1. the control plane sets the basic configuration of the EOS service;
basic configurations of EOS traffic include creation of cpos slots, creation of vcg, binding of slots to vcg, and association of vcg with ethernet ports.
2. The control plane sets the content, maximum rate, minimum rate and time duration of the sending message.
The content of the sent message is the message content transmitted on the network, the maximum rate is the rate of sending the message for the first time, the minimum rate is the rate for calculating the next sending, and the duration is the duration of sending the message.
3. The control plane calculates the rate by a dichotomy method until the maximum throughput is obtained.
In the manner of calculating the rate by bisection, the control plane sets initial highest rate and lowest rate values, namely RateHigh and RateLow. The rate currrate of the first transmission is equal to RateHigh. If the sending rate is curRate, if the lot is not greater than the PermitLost, curRate is the maximum throughput rate of the current RFC2544, otherwise, the next sending rate is calculated downward by bisection method, where RateHigh is curRate, RateLow is RateLow, and curRate is (RateHigh + RateLow)/2. As a result of the currrate transmitted at this time, if the low is not greater than the PermitLost, the bisection method calculates the next transmission rate upward, where RateHigh is RateHigh, RateLow is currrate, and currrate is (RateHigh + RateLow)/2. Otherwise, the bisection method calculates the next transmission rate downwards, where RateHigh ═ currrate, RateLow ═ RateLow, and currrate ═ RateHigh + RateLow)/2. Until (RateHigh-RateLow) <2, currrate is the maximum throughput.
4. The forwarding plane is responsible for analyzing the message content and delivering the message content to a specific output interface according to a target IP or a label.
Compared with the prior art, the network interconnection equipment evaluation method based on the EOS service can realize more convenient understanding of throughput, packet loss rate, time delay and back-to-back of the EOS service under the conditions of some testing environments and incomplete testing tools.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
As shown in fig. 1, the method for evaluating network interconnection equipment based on EOS service according to this embodiment is based on RFC2544 test equipment and remote loopback equipment, where the RFC2544 test equipment specially sends a message to the remote loopback equipment, and the remote loopback equipment loops the message to the RFC2544 equipment after processing, and includes the following steps:
s100, setting basic configuration of an EOS service by a control plane;
s200, the control plane sets the content, the maximum rate, the minimum rate and the time duration of the sending message;
s300, calculating the rate by the control plane through a dichotomy method until the maximum throughput is obtained;
s400, the forwarding plane is responsible for analyzing the message content and delivering the message content to a specific output interface according to the target IP or the label.
Wherein, the basic configuration of the EOS service in S100 includes: creation of cpos slots, creation of vcg, binding of slots to vcg, and association of vcg with ethernet ports.
The content of the message sent in S200 is the message content transmitted over the network, the maximum rate is the rate at which the message is sent for the first time, the minimum rate is the rate used for calculating the next sending, and the time duration is the duration of sending the message.
The S300 control plane calculates the speed by a dichotomy method until the maximum throughput is obtained; the method comprises the following specific steps:
in the mode of calculating the speed by bisection, the control plane sets initial highest speed and lowest speed values, namely RateHigh and RateLow;
the rate currrate of the first transmission is equal to RateHigh;
if the sending rate is curRate, if the lot is not greater than the PermitLost, the curRate is the maximum throughput rate of the current RFC2544, otherwise, the dichotomy calculates the next sending rate downwards, where RateHigh is curRate, RateLow is RateLow, and curRate is (RateHigh + RateLow)/2;
if the result of the currrate transmitted at this time, that is, the low is not greater than the PermitLost, then the bisection method calculates the next transmission rate upward, where RateHigh is RateHigh, RateLow is currrate, and currrate is (RateHigh + RateLow)/2;
otherwise, the bisection method calculates the next sending rate downwards, wherein RateHigh equals curRate, RateLow equals RateLow, and curRate equals (RateHigh + RateLow)/2;
until (RateHigh-RateLow) <2, currrate is the maximum throughput rate
As can be seen from fig. 2 and 3, the specific operation steps of the embodiment of the present invention are as follows:
firstly, as shown in a test data stream networking diagram of fig. 1, a network in which two test devices are butted through a CPOS interface or a network built by the test devices are built, and the two test devices are RFC2544 test devices and remote loopback devices respectively. The RFC2544 device specially sends the message to the far-end loopback device, and the far-end loopback device loops the processed message back to the RFC2544 device so that the RFC2544 device can count the packet loss rate, the time delay, the throughput rate and the like.
According to the relevant configuration of the user, the parameters are sent to the control plane and the forwarding plane, and as shown in fig. 2, when the test starts, the configured maximum rate is first used as the currently sent initial rate. (1) After the message is sent out from the RFC2544 test device, the message passes through the intermediate network, and reaches the far-end loopback device as shown in fig. 1, and the far-end loopback device sends the processed message back to the RFC2544 test device. At this time, the RFC2544 device performs packet receiving statistics to calculate the packet loss rate; (2) recording the sending and receiving time of the data packet through the sent data packet, and calculating the time delay; (3) then calculating the maximum throughput through a dichotomy; (4) and the equipment can completely forward all the sent data packets, calculate the back-to-back value and finish the process.
