BIST FastCOM

Bist FastCOM is highly scalable, very fast and reliable stream transmitter library. It is mainly designed to elavate the capabilities of UDP to provide reliable and fast data transmission by using.

Package comes with

Tools

FastCOM also comes with handy command-line utilities that help u create/remove shared-memory, set shared-memory parameters and load data to the specified shared-memory.

ManageIPCS

Creates and removes IPC with MDSTStreamHeader struct:

struct StreamHeader
{
   struct sockaddr_in InfAddr;
   struct sockaddr_in RecoveryClientAddr;
   struct sockaddr_in RecoveryServerAddr;
   unsigned int MPListMPIdx;
   unsigned int MPListRPIdx;
   unsigned int StreamSize;
   unsigned int MPListSize;
   unsigned int MPListSem;
   struct MissingPage EOSRcvrPage;
   char EOSRcvrBufr[MAX_RCVR_PAGE_LEN];
};

This utility takes 4 arguments:

1. id of shared memory
2. operation (CREATE or REMOVE)
3. size of MissingPage struct (for recovery channel)
4. size of the stream data to be hold in shared memory

Example usage:

$ ./ManageIPCS 2 CREATE 65535 268435455
$ ./ManageIPCS 2 REMOVE

MDST_SetPrm

Assign values for socket addresses described in the struct below.

This utility takes 4 arguments:

1. id of shared memory
2. which socket value to assign (INF_ADDR, RCVR_SRVR_ADDR or RCVR_CLNT_ADDR)
3. IPV4 address for the socket
4. port number for the socket

Example usage:

$ ./MDST_SetPrm 2 INF_ADDR        0.0.0.0    2001
$ ./MDST_SetPrm 2 RCVR_SRVR_ADDR  0.0.0.0    2002
$ ./MDST_SetPrm 2 RCVR_CLNT_ADDR  127.0.0.1  2002

MDST_ManagePacketLog

You can save the data from shared memory to a file OR you can load data to shared memory at once.

This utility takes 3 arguments:

1. id of shared memory
2. operation (LOAD or SAVE)
3. filename to save or load

Example usage:

$ ./MDST_ManagePacketLog 2 LOAD data_load_file
$ ./MDST_ManagePacketLog 2 SAVE data_save_file

MDST SENDER

MDST_Sender

Sends shared memory data via broadcast.

This utility takes 2 arguments:

1. id of shared memory
2. loop number for send the other paket

Example usage:

$ ./MDST_Sender 2 2000
$ ./MDST_Sender 2 0

MDST_RecoveryServer

Sends shared memory data if broadcast not received by receiver.

This utility takes 1 arguments:

1. id of shared memory

Example usage:

$ ./MDST_RecoveryServer 2

MDST RECEIVER

MDST_Receiver

Receives data via broadcast and write to shared memory.

This utility takes 1 arguments:

1. id of shared memory

Example usage:

$ ./MDST_Receiver 1

MDST_RecoveryClient

Requests data if broadcast not received and receives data that send from MDST_RecoveryServer.

This utility takes 1 arguments:

1. id of shared memory

Example usage:

$ ./MDST_RecoveryClient 1
