C# Class Microsoft.Protocols.TestTools.StackSdk.RemoteDesktop.Rdpbcgr.TS_FP_UPDATE_PDU

Fast-path revises server output packets from the first byte with the goal of improving bandwidth. The TPKT (see [T123]), X.224 (see [X224]) and MCS SDin (see [T125]) headers are replaced, the Security Header is collapsed into the fast-path output header, and the Share Data Header is replaced by a new fast-path format. The contents of the graphics and pointer updates (see sections and ) are also changed to reduce their size, particularly by removing or reducing headers. Support for fast-path output is advertised in the General Capability Set.

Property Details

dataSignature public_oe property

8 bytes. Message authentication code (MAC) generated over the packet using one of the techniques specified in section (the FASTPATH_INPUT_SECURE_CHECKSUM flag, which is set in the fpInputHeader field, describes the method used to generate the signature). This field is present if the FASTPATH_INPUT_ENCRYPTED flag is set in the fpInputHeader field.
public byte[] dataSignature
return byte[]

fipsInformation public_oe property

Optional FIPS header information, present when the Encryption Level selected by the server (see sections and ) is ENCRYPTION_LEVEL_FIPS (4). The fast-path FIPS information structure is specified in section .
public TS_FP_FIPS_INFO,Microsoft.Protocols.TestTools.StackSdk.RemoteDesktop.Rdpbcgr fipsInformation
return TS_FP_FIPS_INFO

fpOutputHeader public_oe property

An 8-bit unsigned integer. One-byte bit-packed header. This byte coincides with the first byte of the TPKT Header (see [T123] section 8), which is always 0x03. Two pieces of information are collapsed into this byte:Encryption dataAction code The format of the fpOutputHeader byte is described by the following bitmask diagram:
public byte fpOutputHeader
return byte

fpOutputUpdates public_oe property

An array of TS_FP_UPDATE structures (variable number of bytes) containing a collection of fast-path updates to be processed by the client.
public TS_FP_UPDATE[],Microsoft.Protocols.TestTools.StackSdk.RemoteDesktop.Rdpbcgr fpOutputUpdates
return Microsoft.Protocols.TestTools.StackSdk.RemoteDesktop.Rdpbcgr.TS_FP_UPDATE[]

length1 public_oe property

An 8-bit unsigned integer. If the most significant bit of the length1 field is not set, then the size of the PDU is in the range 1 to 127 bytes and the length1 field contains the overall PDU length (the length2 field is not present in this case). However, if the most significant bit of the length1 field is set, then the overall PDU length is given by the low 7 bits of the length1 field concatenated with the 8 bits of the length2 field, in big-endian order (the length2 field contains the low-order bits).
public byte length1
return byte

length2 public_oe property

An 8-bit unsigned integer. If the most significant bit of the length1 field is not set, then the length2 field is not present. If the most significant bit of the length1 field is set, then the overall PDU length is given by the low 7 bits of the length1 field concatenated with the 8 bits of the length2 field, in big-endian order (the length2 field contains the low-order bits).
