SOE's Protocol is a systematic way to enhance the UDP protocol to make it more reliable, and also save bandwidth by merging and grouping packets. It can be combined in various ways, or not be used at all.
 
SOE's Protocol is a systematic way to enhance the UDP protocol to make it more reliable, and also save bandwidth by merging and grouping packets. It can be combined in various ways, or not be used at all.
  
 
The format of the SOE Protocol varies depending on what type of operation it is. SOE Protocol can function as a stand alone packet, or as a Header to SWG Packets. What is true about all of the SOE Protocol is that the beginning contains 2 bytes known as the SOE Opcode. Majority also contain a footer. Assume all packets have footers unless otherwise mentioned. The table of opcodes are as follows:

The first byte will be 0xFF. The next byte will be 0x01. The following byte will be how much to add to 255. Because no packet can exceed 496 bytes, The 3rd bye will never exceed 0xFF. We believe the 0x01 is the amount of following bytes to add to 255, but that cannot be determined.

Guides - SOE Protocol Breakdown

SWGANH Wiki is a repository of Star Wars Galaxies Developer information. This site is only meant to be used by SWGANH Developer team.

SOE's Protocol is a systematic way to enhance the UDP protocol to make it more reliable, and also save bandwidth by merging and grouping packets. It can be combined in various ways, or not be used at all.

The format of the SOE Protocol varies depending on what type of operation it is. SOE Protocol can function as a stand alone packet, or as a Header to SWG Packets. What is true about all of the SOE Protocol is that the beginning contains 2 bytes known as the SOE Opcode. Majority also contain a footer. Assume all packets have footers unless otherwise mentioned. The table of opcodes are as follows:

Note An SOE Opcode is stored as an unsigned short (uint16), and is in net byte order.


SOE OpCodes 
(SOE Opcode)"in hex"	(Meaning) 		(       (ENUM_NAME) "used in code"

00 01		Session Request				(SOE_SESSION_REQUEST)
00 02		Session Response			(SOE_SESSION_REPLY)
00 03		Multiple SOE Protocols			(SOE_MULTI_SOE)
00 04		Not Used				(SOE_NOT_USED)
00 05		Disconnect				(SOE_DISCONNECT)
00 06		Keep Alive				(SOE_PING)
00 07 		Client Network Status Update		(SOE_NET_STATUS_REQ)
00 08 		Server Network Status Update		(SOE_NET_STATUS_RES)

00 09 		Channel 0 - Data Packet			(SOE_CHL_DATA_A)
00 0A		Channel 1 - Data Packet			(SOE_CHL_DATA_B)
00 0B		Channel 2 - Data Packet			(SOE_CHL_DATA_C)
00 0C		Channel 3 - Data Packet			(SOE_CHL_DATA_D)

00 0D		Channel 0 - Fragmented Data Packet	(SOE_DATA_FRAG_A)
00 0E		Channel 1 - Fragmented Data Packet	(SOE_DATA_FRAG_B)
00 0F		Channel 2 - Fragmented Data Packet	(SOE_DATA_FRAG_C)
00 10		Channel 3 - Fragmented Data Packet	(SOE_DATA_FRAG_D)

00 11		Channel 0 - Out of Order Packet		(SOE_OUT_ORDER_PKT_A)
00 12		Channel 1 - Out of Order Packet		(SOE_OUT_ORDER_PKT_B)
00 13		Channel 2 - Out of Order Packet		(SOE_OUT_ORDER_PKT_C)
00 14		Channel 3 - Out of Order Packet		(SOE_OUT_ORDER_PKT_D)

00 15		Channel 0 - Acknowledge Packet		(SOE_ACK_A)
00 16		Channel 1 - Acknowledge Packet		(SOE_ACK_B)
00 17		Channel 2 - Acknowledge Packet		(SOE_ACK_C)
00 18		Channel 3 - Acknowledge Packet		(SOE_ACK_D)

00 19		Channel 0 - Multi SWG Packets		(SOE_MULTI_SWG_A)
00 1A		Channel 1 - Multi SWG Packets		(SOE_MULTI_SWG_B)
00 1B		Channel 2 - Multi SWG Packets		(SOE_MULTI_SWG_C)
00 1C		Channel 3 - Multi SWG Packets		(SOE_MULTI_SWG_D)

00 1D		*Serious Error Acknowledge		(SOE_FATAL_ERR)
00 1E		*Serious Error Reply			(SOE_FATAL_ERR_REP)

Note These functions are seen on very malformed packets. Very rare occurance and the client will usually disconnect. It's inclusion in the documentation is for completion ONLY. SWGEmu will disconnect automatically when reciving a Error Acknowledge, and it will NOT send any, rather just disconnect itself.


SOE has their protocol premade to allow various channels of data transmission. However, no game to this date utilizes the multiple channels. SWG will only be using channel 0 and it will be assumed throughout the rest of the packet documentation.


The following data is of packet breakdowns and explainations on each type. See the article "Packet Breakdown Format" for information on the specific used for documentation.

Packet Type -- 00 01

Packet Type 00 01 
00 01  -  Session Request (Client -> Server)
SOE Opcode	- Net Byte SHORT	
CRC Length	- Net BYte INT
Connection ID	- Net Byte INT
ClientUDPSize	- Net Byte INT
  • SOE Opcode is just the opcode number to identify the packet.
  • CRC Length is the amount of length of the CRC checksum to append at the end of a packet. SWG uses 2 bytes.
  • Note CRC32 checksums are 32bit, making them 4 bytes, but only 2 are appended.
  • Connection ID is some type of identification used for the connection. Only other time seen is during a disconnect.
  • ClientUDPSize is the maximum size allocated for the client's UDP packet buffer. No packet is allowed to exceed this size. If it is larger, it must be fragmented. This size is equal to 496 bytes.

Note This opcode DOES NOT have a footer.

Packet Type -- 00 02

Packet Type 00 02 - Session Response (Server -> Client) 
SOE Opcode	 - Net Byte SHORT
Connection ID	 - Net Byte INT
CRCSeed		 - Net Byte INT
CRCLength	 - BYTE
UseCompression   - BYTE
SeedSize         - BYTE
ServerUDPSize	 - Net Byte INT
  • Connection ID is replied using the same ID sent by the Session Request.
  • CRCSeed is a seed value used for the calculation of the CRC32 Checksum.
  • CRCLength
  • UseCompression 0/1 Compression on/off
  • SeedSize Size in bytes for the XOR encryption key. Strange that this appears after the CRCSeed. Seed seems to have a max value of 5bytes. Standard is 4
  • ServerUDPSize is the maximum size allocated for the server's UDP packet buffer. No packet is allowed to exceed this size. So far the client has not sent anything large enough to fill this, or be fragmented. This size is equal to 496 bytes.

Note This opcode DOES NOT have a footer.

Packet Type -- 00 03

Packet Type 00 03 - Multiple SOE Protocols(Various) 
SOE Opcode	- Net Byte SHORT
Data Size	- (VARIOUS)
DATA		- (VARIOUS)
Data Size	- (VARIOUS)
DATA		- (VARIOUS)
...

These packets allow the combination of 2 or more SOE Protocol packets or stand alone SWG Packets with SOE Protocol packets.

(SOE Protocol)((SOE Protocol)(SWG Packet)) or (SOE Protocol)(SWG Packet)

or as a better example:

(Multiple SOE Proto)(Ackowledge)(Data) or (Multiple SOE Proto)(Acknowledge)(SWG Packet) or (Multiple SOE Proto)(Acknowledge)(Acknowledge)

Each seperate packet is preceded by it's size. So a better example would be: (Multiple SOE Proto)(size1)(Acknowlede)(size2)(Data)

so a very basic hexadecimal version would be: 

(00 03)  (04)  (00 15 00 00)  (0A)  (00 09 00 01 01 00 FF FF FF FF)
 multi   size   acknowledge   size              data
  • NOTE: The Size field will never exceed 255.

Packet Type -- 00 05

Packet Type 00 05 - Disconnect (VARIOUS) 
SOE Opcode	- Net Byte SHORT
Connection ID	- Net Byte INT
Reason ID	- Net Byte SHORT
  • Connection ID is the ID number assigned during the session request. Each client sends its own Connection ID. Reason ID is an ID number that corresponds for a reason for the disconnection.

This packet is sent whenever one side wants to disconnect. It resends the clients specific Connection ID established during the session handshake, and then a reason for disconnection. The possible disconnect reasons and the associated ID seen in the packet are in the table below.

ID String
0 None
1 ICMP Error
2 Timeout
3 Other side terminated
4 Manager deleted
5 Connect fail
6 Application
7 Unreachable connection
8 Unacknowledged timeout
9 New connection attempt
10 Connection refused
11 Mutual connect error
12 Connecting to self
13 Reliable overflow

Packet Type -- 00 06

00 06 - Keep Alive(VARIOUS) 
SOE Opcode	- Comp / CRC

This packet is simply a keep alive to tell the other side that is still connected, but idle. It only consists of the opcode and a footer.

This packet is supposed to contain the Servers network statistics, however we felt it was a waste of time to reverse these as we do not care about the statistics. Instead we send 38 bytes of 0x00, and then compress the packet, but skip appending a CRC. The client seems to register that it recieved the servers statistics, but notices a bad CRC (or none in our case), and tosses out the packet as malformed. Because it recieved the packet it continues on without erroring.

Note: This packet is usually compressed but is optional.

Sequence # is a sequence number applied to every data packet. It increments in order for each packet and is used to help determine out of order packets. This protocol is used to send an SWG Packet that NEEDS to be recieved by the other end. The reciver is then supposed to respond with a an ACKNOWLEDGE packet that contains the same sequence so the sender knows it has been recieved. This system ensures packets not only get sent correctly, but also stay in order.

After the sequence # comes the encapsulated SWG Packet.

Note* it is possible to combine multiple SWG PACKETs into a single 09. This is done similar to the 0x0003 packet, a multi data example: 

(00 09) (sequence) (00 19) (Size1) (SWG PACKET) (Size2) (SWG PACKET)
SOE op.  sequence   multi   size       data       size      data

if the Size byte is FF the following 2 bytes are the size Word Little ended (16bit). Example: 

(00 09) (sequence) (00 19) (size byte) (size word) (SWG PACKET) (size byte) (SWG PACKET)
SOE op.  sequence   multi    FF          01 99        data         33          data

In the above the first packet size is 409 Dec.

Use these to combine SWG PACKETs together into 1 data packet/sequence number.

  • Sequence # is the same type of sequence number described in the "00 09 - Channel 0 Data" section. All the same rules apply.
  • FragmentSize is the total size of the combined fragments. This only appears in the FIRST packet of a group of fragmented packets.

Next is just the piece data of the large SWG Packet. Fragments are made when the total UNCOMPRESSED packet exceeds the packet buffer size, which is 496 bytes.

Packet Type -- 00 11

Packet Type 00 11 - Out of Order Packet 
SOE Opcode	- Net Byte SHORT
Sequence #	- Net Byte SHORT

Sequence # is the sequence number of the out of order packet recieved. It will send one for every packet that is out of order, and the ones following.

So if packet sequences recieved are: 

00 00
00 01

And then: 

00 03

an out of order will be sent for the packet with sequence 00 03.

If the packet sequences recieved are: 

00 00
00 01

And then: 

00 03
00 04
00 05

An out of order packet will be sent for all 3 of the out of order sequences.

Packet Type -- 00 15

Packet Type 00 15 - Acknowledge 
SOE Opcode	- Net Byte SHORT

  • Sequence # is the sequence number of the packet to acknowledge to the sender that it was recieved correctly.

Every packet sent with a sequence number MUST be acknowledeged.

They do not neccesarily need to be Acknowledeged 1 by 1. For example: If packet sequences recieved are: 00 00 00 01 00 02

An Acknowledge of 00 15 00 02 will cover all the packets up to the sequence 00 02.

The client will stop processing packets after about 4 unacknowledeged packets so frequent acknowledges are needed.
