Abstract

In a method for developing a communication protocol for transmitting binary instructions between devices in a network, each instruction comprising at least one of a binary transmitter identifier, a binary receiver identifier and a binary operation identifier, a set of alphanumeric identifiers for each transmitter of the network is determined, each alphanumeric identifier having the same number of characters. Then a set of binary transmitter identifiers having a same number of bits is generated by converting each alphanumeric identifier of said set into a binary identifier using a compression function. Finally binary instructions are formed having as transmitter identifiers a binary transmitter identifier from said set.

determining a set of alphanumeric identifiers for each operation identifier and each transmitter or receiver of the network, respectively, each alphanumeric identifier having the same number of characters;

generating a set of binary operation identifiers and transmitter or receiver identifiers, respectively, each type of binary identifier having a same number of bits, by converting each alphanumeric identifier of said set into a binary identifier using a compression function, wherein the compression function is the same for each type of identifier; and

forming binary instructions having as transmitter, receiver, or operation identifiers, respectively, a binary identifier from said set.

2. Method according to claim 1, wherein the number of bits is the same for each type of identifier.

3. Method according to claim 1, wherein each alphanumeric character has an integer numeric value unambiguously assigned to it, and the compression function has the form

F(A)=( . . . ((s[a₀]*c+s[a₁])*c+s[a₂])* . . . )*+s[a_n-1],

n being the number of alphanumeric characters in the alphanumeric identifiers,

s[a_i], i=0, 1, . . . , n−

1 being a numerical value assigned to the i-th alphanumeric character a_i of identifier A,

c being an integer larger than the largest one of said integer numeric values.

4. Method according to claim 3, wherein the set of alphanumeric characters comprises between 36 and 63 different characters.

5. Method according claim 1, wherein the number of bits in each binary identifier and the number of bits simultaneously processed by an instruction in a processor of any of the devices of the network are identical.

6. Method for operating a network comprising the steps of transmitting a binary instruction between devices of said network using a protocol obtainable by a method according to claim 1;

and

receiving said binary instruction and transforming an identifier of the received binary instruction into alphanumeric form using a decompression function inverse to said compression function.
